Written Review

Easy Motion is one of the only mainstream electric bike makers to deliver an all-wheel drive electric fat bike and the result is pretty impressive. You can actually specify that the bike use just the rear motor, just the front motor, a combination of the two (for a zippy start with efficient cruising) or two-wheel operation with a bit of traction control… where the motors pass power back and forth if one starts to slip. This would be an excellent ebike to use in soft sandy conditions or the snow and Easy Motion sells an optional Neoprene cover to help insulate the battery from the cold (allowing it to last longer). With a 16-speed drivetrain that is independent of the motor, you can switch gears without the strain and mashing that some mid-drives are known for and the 180/160 mm hydraulic disc brakes stop the bike and the motor systems when pulled. They are ebike specific and help to cancel out a bit of motor delay that the Emotion Evo products are known for. All in all, the bike feels smooth and powerful without sounding as loud as it might on concrete only (you can hear the differences in the video review above). I found that it climbed well, the front motor kept the front tire from pushing soft terrain and losing traction and instead pulled me forward, and I love the balanced weight distribution. There are a few missing pieces to this product in my opinion including the lack of a viable kickstand mount, bottle cage bosses and singular charge interface (you have to use a dongle to charge the battery when it’s off the bike) but for the price, it’s pretty well done.

Driving the bike are two Dapu planetary geared hub motors, the rear is rated at 350 watts nominal and the front at 250 watts. At first, I was surprised that a heavier bike like this wouldn’t be using the new 500 watt motor that other Evo products from Easy Motion have adopted. I wasn’t sure how it would perform on steeper hills and really questioned the 250 watt up front. It’s easy to get distracted by numbers in this industry because some electric bikes have 750 watt rated motors! But the experience, the actual climbing, changed my mind. Instead of feeling weak or struggling, the motors got me and my friend Mark up a steep dirt hill and I could actually feel the front motor pulling me and maintaining traction in places where other models had slipped. The combination of larger 4″ wide fat tires and two high-torque motors results in an impressive experience. The real benefits of these compact hub motors include efficient use of battery power, reduced weight on the bike (and especially on the front wheel where it might otherwise impact steering) and a blended design that doesn’t stand out as some crazy ebike contraption. I’m very fond of the way this bike performs, it’s the best all-wheel drive ebike I have tested and while the cable for the front motor is a bit exposed and could get snagged, the rear motor cable is very tucked in and the rest of the cables are all internally routed. That front cable is no different from a lot of lower-end ebikes and it shouldn’t be an issue… but on a platform where everything else is so well done and durable, that’s one area I’d be careful with.

Powering the two motors and the backlit display panel is an efficient 48 volt 12.6 amp hour battery pack. With over 600 watt hours of capacity, it’s larger than most of the other products out there and that’s a good thing when you’re lumbering along in the snow. Not only is snow a challenge to navigate and push through, it usually exists on colder days and that can impact effective battery capacity. You may have charged the pack up to 100% but if it gets cold, you just won’t get the range you might have otherwise. To address this, Emotion sells a zippered Neoprene cover that fits around the battery and downtube to insulate it from wind and cold air. It’s just like the Neoprene slap guard on the right chainstay but larger. There’s a lot to celebrate about this battery, just how seamlessly it fits into the frame and how nice it looks being paint-matched… but there are some difficulties and shortcomings as well. Becasue the battery seats down into the downtube, you have to pull it up when removing. This process gets the lower edge of the pack VERY close to the seat tube where it could bang and chip. The paint on the pack looks good but is white underneath so any scratches or chips that you take on will show and look bad. Once the pack is off of the bike, it can be difficult to grip and carry (no handle and smooth surfaces). It’s 8.2 lbs which is quite a bit heavier than other ebike packs and charging it requires a dongle piece be added to the standard plug. There is a little plastic wingnut to help secure this dongle but I feel it would be easy to misplace and wish the pack and frame charging ports were the same so the dongle wouldn’t be required at all. I do like that at least the battery has a little LED display to give you charge level even when it’s off the bike. This makes it easier to maintain when not in use for longer periods (charge it every couple of months and store in cool dry locations).

Powering the bike on is very intuitive and requires fewer steps than some products. Just charge and mount the battery then hold the center button on the display panel for several seconds. I do mean several… because it’s not as quick as some other displays I’ve tested. Do not press on the cranks or ride when power the system on because it takes some measurements as it boots up and this can confuse the systems and make it ride differently than you might want. Once the display is on, it shows battery level, speed and assist level of which there are four different steps. You can definitely ride this ebike unpowered but there is no throttle and with the heavier footprint of nearly 65 lbs it might not be fun, even in the lower gears offered. I usually arrow up to the second level for easy terrain and jump way up to the highest levels for any sort of climbing. Arrowing up or down is easy using the plus and minus keys on the left side of the faceplate. If you hold the minus key for a couple of seconds it turns on backlighting and if you hold plus and minus together it enters into the settings where you can change from standard to metric, adjust wheel size (if you swap the wheels for some reason) and adjust from rear, front, eco or all wheel drive. One thing I noticed about the display when riding is that it can estimate your range (just click the power button a few times until trip stats go from distance and avg. speed readouts to something that says “m to go” which stands for miles to go. It’s not dynamic, meaning it won’t change as you arrow up or down through different assist levels, but it’s better than nothing and compliments the battery percentage readout nicely. I prefer having more info than less on how my battery capacity is doing, especially on heavier off-road e-bikes like this because it’s no fun walking them home ;)

It’s probably clear that I like this bike… It’s really just surprising how well it works and it’s a one of a kind system. In a world where more bikes have a Bosch mid-drive, I love this variety and feel that Easy Motion has balanced style, performance and weight well. You get some higher-end components and a two year warranty (that can be upgraded to five years if you register) as well as access to a wide dealer network worldwide. Easy Motion was one of the first big brands to enter the United States but its parent company, BH, has been operating out of Spain for over 100 years since 1909. They design their ebikes to blend in with non-electric bikes and emphasize the experience of riding. As a Class 1 electric fat bike, this is designed to be allowable on more trails than if it had a throttle and it’s quiet enough that most people probably wouldn’t notice it’s any different than a normal fat bike. I do wish it had a kickstand and feel that they could have squeezed in some bottle cage bosses at the seat tube for use with a side-entry cage, a 180 mm rear disc brake rotor would have been nice vs. 160 mm just given the size and weight of the bike but the hydraulic setup they used is good enough. Overall, it’s a solid offering in a space with very few entrants.


  • Given the heavier weight of this ebike, nearly 65 lbs, I’m glad they offer more gears to pedal with (16 combinations in total), just in case the batteries run low or you want to challenge yourself unpowered
  • With a little bit of extra weight in both wheels and the battery weight low and center on the frame, this is a balanced electric bike that handles better on trails
  • The battery mounts almost seamlessly on the lower mid-section of the frame and the hub motors are compact enough that they blend right in, the bike doesn’t stand out as being electric
  • Easy Motion further updated their quick release systems from past years and while only the rear wheel has it on this bike, I like that it’s an alloy lever on the left side only vs. the older plastic levers that were on both sides
  • The motors are zippy and powerful, the two-wheel drive feature actually works and depending on what mode you use it can be quite efficient (front wheel, eco or all wheel drive), though they do produce a bit more noise than some given the weight of the bike and their smaller sizes
  • Solid hydraulic disc brakes 180/160 offer the stopping power you need for the weight and intended use of this electric bike, whether it’s snowy streets, light trail riding or some time at the beach in sand… the brakes are responsive and even have motor inhibitors built in to cut power as soon as you squeeze them, I also like that they have adjustable reach in case you’re wearing gloves
  • Emotion sells this cool Neoprene cover that zips over the downtube (and battery) to keep it warmer in cold riding conditions and helps to extend range, when batteries get extremely cold they tend to dissipate quicker and since this is an AWD fat ebike which is snow-capable it’s the perfect use case for the Neoprene cover, the bike comes stock with a smaller Neoprene slap guard on the right chainstay to keep the frame chip-free
  • In All-Wheel-Drive mode, the control system can sense if a wheel is slipping and transfer more power to the other motor… it’s like traction control
  • While it isn’t exactly cheap at $3,500, I feel like the Evo Big Bud Pro offers great value for the price considering most of the other Evo models from Easy Motion are $3k and they only have one motor and aren’t fat tire bikes which use more materials
  • At ~600 watt hours, the battery capacity here is higher than average but given the weight and off-road use, that’s important, the 48 volt system sends power more efficiently than the older 36 volt
  • I love how small the display is… but that it has a fairly large display and is easy to reach and use… but most of all I love that it’s removable! this reduces sun damage, scratching and theft
  • There’s a deep bend in the top tube which brings the standover height lower, this is great for people with shorter inseams or those wearing snow pants that might sag down :D


  • Unfortunately, no bottle cage bosses have been added to the frame, it seems like there was space lower down on the seat tube (especially given there is only one frame size here) but at least they added rear rack bosses so you could mount a fat bike specific rack and carry a trunk bag with bottle holster like this
  • No kickstand and I’m not sure how easy it would be to add one of your own aftermarket, some ebikes have a hole near the bottom bracket or a metal plate near the left dropout… and the Big Bud Pro does have holes on the left side but they are crowded by the disc brake rotor so may not be useable, the bike can be leaned against a wall just fine but it’s just a little easier to tip over and given how heavy it is that could cause more damage or harm
  • There’s only one frame size and one color choice, I preferred the all-black look of the older Big Bud Pro but the neon accents here aren’t terrible
  • While the rear hub motor has a power cable that’s tucked in and very well situated out of the way, the front hub motor isn’t fat bike specific and has a wire that extends out and might be prone to snagging or bending if the bike tips (which could ruin it if the cable frays or breaks)
  • Some fat-tire ebikes are starting to offer suspension forks to further cushion the ride (if you ride lower air pressure in the tires they can be quite comfortable on their own), consider swapping the bars for riser or swept-back and adding a 31.6 mm seat post suspension to make the Big Bud Pro more comfortable
  • The key slot and charging port are positioned very close to the crank arms near the bottom bracket and could get snagged or caught, be careful here, I was also bummed that you need a different dongle to charge the battery on the bike vs. on its own off the bike (don’t lose this piece!) I also think the little plastic cap covering the port on the frame should have opened the other way (right to left) so that it would be inline with the direction that the bike normally travels… right now it opens like suicide doors on some older cars
  • Be careful removing the battery pack from the bike frame as it’s easy to bump on the seat tube (since it pulls upward) and if you scratch or chip it, the plastic underneath is white and will start to show… there is also no handle or easy way to grip the battery and at ~8 lbs requires a bit more strength than the other 5 to 6 lbs batteries from Bosch and Yamaha, don’t drop it because that could damage it
  • There’s a bit of delay for the motor to cut out, it’s not as responsive as some multi-sensor ebikes I’ve tried but the brake inhibitors overcome this, also, at times if the chain is bouncing a lot and you’re in a higher level of assist it may activate the motor without you pedaling

Range at cold temp: My intent would be to ride this bike as fast as possible to get to work during winter at 5-10 Farenheit (-10-15C) and at a distance of 12 miles or 20 km. Do you think the range is enough? I could charge it during the day…

What could I expect as an average speed? I am currently riding a BionX 500W rear motor mounted on a old chromoly road bike and making a 31 km/h (19mph) average speed over the entire ride… during summer and fall season.

Thanks, great reviews by the way, the reference on the web for E-bike!

Hello Jean-René, I have not ridden the Evo Big Bud Pro to exhaustion and I only weigh ~135 lbs, but I would guess that a 12 mile ride would be possible… and you could charge at the half way point as you suggested. Worst case scenario is that you could ride partway in a lower assist level when it is flat and smooth. If you are not going through deep snow, soft terrain, or up hills for the entire ride, I think you could expect to make it. Cold weather does have an impact and you might want to buy the Neoprene battery cover and store your pack somewhere more warm before the rides to maximize range. My guess on top speed (if it’s smooth, no wind, no deep snow etc.) would be in the 16 mph to 18 mph range if you use the higher assist and pedal constantly. I hope this helps, without knowing more about your ride conditions and weight it is difficult to guess.

Salut Jean-René, I imagine you’re a Montrealer (or somewhere in Quebec, me too). I bought one of these and my intent is to use all year long… Right now, it’s already amazing (average of 30km/h without forcing too much) and I’m really looking forward to the first snow! BUT I don’t think I would do 30km/h on snowy and icy roads (specially in Montreal with the mega potholes) but I intend to maintain a decent commute time without breaking my neck… Let me know if you have questions about it… J

I recently purchased the FLX Blade and couldn't be happier. After spending the last 8 months dealing with a different, terrible buying experience from another vendor, I got in touch with FLX. Rob, one of the founders, called me back immediately and answered my questions and confirmed that the bike was in stock and ready to ship. I made the purchase on a Thursday and had the bike the following Tuesday morning.

This is the third eBike in my personal fleet. The others are an Easy Motion Evo Cross 48v 500w hub and a Juiced OceanCurrent 48v hub, so I was excited to transition into a mid-drive system. All of the specs listed on the website were 100% accurate. It was packaged and secured perfectly in a box (inside another box) with padding and other instruments to make sure no component on the bike could be damaged in shipping. Following the youtube video for assembling the bike, I had it put together in less than 30 minutes.

This bike is fast. It is scary-fun fast. I mostly ride in eco mode as I'm trying to actually get a workout when I bike, but man... when you put it in SPORT mode and set it to assist-level 5, it's insane. I put on https://www.schwalbetires.com/bike_tires/road_tires/super-moto-x on it for a smoother ride in town... they're great for the road and the hike/bike trails.

I've put on about a 130 miles on it so far and it's been an amazing time! I am in bike-love. Austin is pretty hilly and the Blade just tears it up and is so much more battery-efficient when it comes to drivetrain power. Something that would eat 20% or more battery on the hubs, takes a 1-2% hit to the battery on the same given path. That's not a scientific study, just an observation of riding the same paths everyday.

If you're questioning or considering the Blade, feel free to reach out and I'll give my honest answers to your questions. I'm not affiliated with any eBike company... just became a fan of FLX with this purchase. :)

Hi Sidney-I have the EasyGo street, (same motor and battery) however, based on your question, I would checkout the Speed dongle discussions on this forum that talks about the Bikespeed or Badass box. I would think you would need to get an extra battery due to the size and Amp Hrs on your bike:

@Ed D Good option for short riders. I'm quite happy with my Easy Motion Evo Street (bike is in Avatar) and have no plans to buy something else.

Check out the Stunner LT on the Biktrix website. Appears to check all your boxes except the torque sensing. I have a Biktrix Juggernaut Classic HD and I have the cadence sensing and I'm very happy with it. When I was researching which bike to buy, I called Roshan, the owner of Biktrix on three different occasions, twice he answered the phone and once he called me back within an hour. I am confident he will give you an honest assessment of the bikes he offers.

Personally, I wanted an eBike I wouldn't need to change out parts. I'm not a bike mechanic and I have no intentions on becoming one. I looked for an ebike that would:

1. Fit me (a short female), and have a step-thru frame and 26" tires
2. Match my style of riding (more upright)
3. Match a certain budget I had to work with
4. Have a good solid warranty
5. Come with lights, fenders, rear rack and an integrated battery
6. Have torque sensing, geared rear hub
7. Be able to allow me to ride for 30mi or more

Back in 2015 there weren't nearly as many choices as there are today. Easy Motion was the brand that checked all the boxes and the Evo Street was the obvious choice for me. I got to test ride it's little sister, the Evo Eco, which was the same size frame, and I knew I would enjoy the Evo Street. I ordered my ebike from CrazyLenny's a couple months later and it's been a great choice for my needs.

Sounds like an efficient system. I would expect a great company like Easy Motion to design something that has the rider in mind. This kind of system reminds me of my electric lawnmower with twin power. The system automatically transfers power to the blade that endures the most load which in turn, cuts more efficiently. Thanks for sharing.

Yes, I have seen this bike and got me curious. How well does it perform in the snow opposed to your other single wheel-driven ebikes? Can you actually maintain control without going into sideway skids?
Make a deal at CL and you are bound to walk out with a smile on your face! :)

I have several ebikes but my current favorite commuter is an Easy Motion Evo Snow Pro. It is 48v, all-wheel drive with 29er Schwabe tires and hydraulic brakes. The components are medium quality but fine for commuting. And because the battery is totally integrated into the frame, it doesn't look like an "electric bike" at first glance.

I purchased it new from Crazy Lenny at a price even less than RadPower, Juiced or Biktrix commuter ebikes. The overall build quality is fantastic, no issues in the past year and Easy Motion has a 5-year warranty on frame and electronic components like controller and motor etc and 2-year on battery - which I believe are up there with the industry bests.

The only things I added were a thudbuster seat and rear rack.

I have two 2016 Radrover with +4500 miles between them and just purchased a RadCity Step-Thru for the wife a few weeks ago. I've got caught in a few rain and hail storms with my Radrover and she had zero issues with the mechanical or with the ebike electronics afterwards. Everything is sealed up nice and tight with Rad Power Bikes. We don't get a lot of snow in the southwest and usually don't ride if it is snowy/icy out.

The wife and I really like the Radcity step-thru because of the upright seating position, cruiser style handle bars, 750w rear hub, easy on/off step-thru frame, 2.3 inch plus size tires, adjustable stem, fenders, rear rack, front suspension, 14 ah battery with regen braking, throttle, and very stable at 20 mph. We added the Cloud-9 11.5X12.5 cruiser seat and Bodyfloat suspension seatpost and that made for a very comfy ride on almost any terrain.

One good thing about Rad Power Bikes are they are regular bikes with ebike components added. Any local bike shop, Amazon, or eBay will have parts for this bike if you need to upgrade the bike components. The Rad ebike components are just the LCD, wiring harness, light, controller, battery, or rear hub. Each of those parts are zero maintenance/tuning/firmware upgrades, inexpensive, and easy to exchange if defective.

I was in vacation in California and an EBR forum member suggested I rent the Radcity Step-thru from a local bike shop in Newport Beach to try before I buy. The wife love the step-thru and we were able to take our time and put around 40 miles on the bike in all kinds of commuter situations around Newport Beach (even took the ebike on a ferry).

I would check to see about ebike rentals and plan a weekend trip try or eliminate possible candidates. We did another ebike rental in Santa Barbara and we didn't like the Electra Townie Go or the BH Easy Motion Evo City Wave mid-drives at all compared to the Rad ebikes.

My 2 cents-You mentioned "The Panasonic is a very reliable motor,". There are not very many E-bikes currently that I have seen with this motor. Back in 2015, Easy Motion had one on a race bike. The other motors you have listed are the most well known brands on E-bikes today, for the exception of the TQ120S. Nice post though about motors and their characteristics. I would pick any of those from the list for each selective terrain you will be riding. Just to know they can be serviced is a big plus IMHO.

Today, I decided to wander over to Electric and Folding Bikes Northwest, which is in the Ballard neighborhood about 11 miles away.I checked, and they close at 6, which surprised me. So I headed out at 4:30. Some confluence of circumstances apparently caused massive traffic jams throughout Seattle today, and at 5:45, Google Maps said I was still 20 miles away. I really wished I had an electric bike the whole way. I called and asked the guy if he would mind sticking around for 10 minutes so I could pop my head in and take a look around, and he said he would be happy to.

Electric and Folding Bikes was an entirely different experience than E-Bikes Seattle. They carry more brands and have newer models out. They also carry non-electric bikes and are an actual bike store. The guy I talked to was a lot more knowledgeable that the one at E-Bike. I really was not impressed with E-Bike, but I was very pleased with Electric and Folding Bikes. I did not try to test drive anything because it was late and raining, but we looked at a number of bikes and discussed my needs. He said that with my hills, he would tend to prefer a mid -drive bike. He also said that they can build a custom bike using a kit, but apparently the trade war is going to his those kits hard. I asked him out if a carbon fiber frame could be used, and he said it could, but he would not advise it because when carbon fiber fails, it does do catastrophically. I actually looked that up, and it is amazing.

They had a Specialized Turbo Como and Turbo Vado, which both were impressive and a number from Easy Motion. They also carry Orbea, which is a Spanish brand. Their Keram bike is nice, but their Wild FS mountain bike pretty much steals the show

Looks like it was well received. It sells for $4,700, but bikebling.com has it on sale for $3,760. The frame looks like carbon fiber, but is alloy, and is has a Shimano Motor DU-E8000 motor and a Shimano Steps E8010 500Wh battery

An article came out in ebike-mtb.com four days ago called "The best eMTB motor 2018 – 6 powerhouses go head to head." The Shimano DU-E8000 was one those included. It did not rank them in the end, just compared. But its discussion of the DU-E8000 was very complimentary

"The compact Shimano motor gives developers and engineers the most freedom when designing frame geometries, which explains its popularity with bike designers and engineers. On top of that, it’s a whole kg lighter than the big Bosch Performance CX, which also requires considerably more room for installation and thus limits both the geometry and the positioning of the bearing points. "

"When it comes to displays, bike manufacturers have the choice. Almost every motor supplier offers a number of options and different sizes. For their Brose motor, Specialized dispense with a display altogether and rely on a minimalist charge-indicator placed on the downtube. You also have the option of sending all of the most important data via Bluetooth directly to an external device such a Garmin or a smartphone. With their high-resolution display mounted behind the handlebars, Shimano currently offers the best compromise between integration, legibility, and protection. Shimano also offers a very intuitive remote system which derives from a Di2 shifter and allows you to switch between support levels. "

"Which motor is the best?
If we were exclusively looking for power, the TQ 120S would be the undisputed winner. However its sheer power is difficult to modulate and eats through a lot of energy in the higher support levels – plus not many manufacturers are using it at the moment. The Yamaha PW-X churns out decent amounts of power at low cadence, but eventually runs out of steam when riding at high cadence. Its turbulent nature in standing starts is not to everyone’s liking either.
The Panasonic is a very reliable motor, but its performance loss at a high cadence is irritating at best and the display integration still needs more sorting.
The Bosch Performance CX is currently the most common motor on the market and has repeatedly proven its capability over the years. Thanks to its updated software and the progressive eMTB mode, it is now even better equipped for all off-road scenarios. Unfortunately, its large dimensions and the noticeable drag above the 25-km/h limit is still a major drawback and represents a serious challenge for ebike designers.

Shimano’s STEPS E8000 motor offers the fewest compromises and suits a wider range of applications. Its intuitive operation system and well-balanced power delivery (especially in Trail mode) are truly pleasant – plus the compact design and light weight are the ideal prerequisites for manufacturers to design the perfect eMTB.

The brand-new Brose Drive S motor offers the most natural and controllable ride. If its predecessor was lacking power, the updated version of the Brose motor stands right behind the TQ motor. On top of this, it runs very quietly, can be finely modulated even in the higher support levels, and presents virtually no resistance at speeds above 25 km/h.

However, the motor is only half of the story. Factors such as geometry, suspension, and spec of a bike are the keys to a comfortable, safe, and pleasant ride. When deciding on a bike you should consider all of these decisive factors carefully."

Overall a surprising and somewhat compelling bike. They did not have one these in stock, but I will check their plans. I will try to head back tomorrow to test a few.

If you sensed a rabbit hole developing, you were right. That article refers to a TQ 120S motor that is described as far more powerful than anything else. TQ used to be Cleanmobile but changed its name. The TQ 120S appears to be a radical development. It is very small and extremely powerful.

I only found one bike for sale with the TQ 120S http://www.togoparts.com/marketplace/ad-details/1003913/new-m1-spitzing-race-850-watt-e-bike-carbon-colour

[QUOhttps://http://www.radpowerbikes.com/products/radrover-electric-fat-bike?variant=1121017969TE="Rooster, post: 120185, member: 15666"]Yes but this ocean current already has vee tire co. Speedster 2.80x26 fat tires and looks the roll[/QUOTE]

I actually got the idea from watching youtube video's of actual e-bike product demonstrations that featured bikes with both front and rear wheel electric hub motor drives; now with both front and rear wheel electric hub motor drives engaged with the ground all the time one can actually ride on the beach even thru dry and/or wet sand without getting potentially stuck; while at the same time being also able to go directly thru muddy trails without getting potentially stuck; to be able to actually have a powered e-bike that is actually capable of powering as if one had the equivalent of all terrain 4wd for a bicycle is something that can be realized with a relatively modest additional investment in ones existing e-bike purchase;

for example consider the Radrover E-Bike Fat Tire Bike for $1499(link below); just imagine the actual potential possibilities of having an all terrain 4wd fat tire E-Bike with a powered front wheel electric hub motor drive; yes one can go on amazon and literally add a 750 watt powered front wheel electric hub motor for a relatively modest e-bike upgrade cost; that would give even the Juiced Bikes Hyperfat E-Bike that is currently still in product development; some rather serious no nonsense E-Bike fat tire ultra performance potential market competition at a very competitive price point offering to boot easily under $2,000;

which is still a very easy modest doable post purchase e-biker end user upgrade project that can actually be purchased right now as we speak(all component parts needed); and yes it would be a turbocharged version of Juiced Bikes Hyperfat with 500 watts in your case combined with 750 watts from front powered front wheel electric hub motor drive; for a combined 1250 watts or 1.25Kw of pure 4wd turbocharged performance one could literally in fact go up a truly massive 25 degree hilly incline if actually needed or if the need ever potentially arose; heck I might just go looking for a 25 degree incline to actually see how it does performance wise to witness and experience the e-bike performance wow factor before and after the turbocharging of the Hyperfat Ebike;

now one of course might have to contact Court and have him do a performance test evaluation review of ones end user post purchase modified E-Bike whether its a CCS, OceanCurrent, or even a custom modified RadRover E-Bike; especially if one also added a Cycling Analyst 3.0(by Grin Technologies) to actually control and customize the end user actual output power levels going to the motor controller that would be delivering the actual adjustable variable output power to the front wheel electric hub motor drive; all to deliver a end user totally customizable 4wd turbocharged surrealistic terra firma ground gripping engaging 4wd E-Biking experience;

as that is truly something that may not have been done before or be directly customized and/or adjusted by the end user in "real time" on the fly; one could for example easily adjust for more or less desired end user target objective needed customized power going to the forward front wheel electric hub motor drive in relative comparison to the actual power going to the rear wheel electric hub motor drive; now the end user might be able to actually go into the Cycling Analyst and set up a custom power level preset to deliver an end user defined custom output power level going to the motor controller that would be effectively delivering and transferring a certain amount of end user pre-defined usable output power to the front wheel on demand.

One can literally turn it into a super cool urban assault commuter bike; by swapping out the default tires for the higher end Kenda Juggernaut Fat Bike tires; just imagine for a moment riding up intense mountain trails being a breeze to pedal and having the time of ones lives cycling enjoying the great outdoors e-biking; now the dual forward and rear electric hub motor pedal assist experience would be nothing short of amazing to realize in real life; by being able to take on mountain trails terrain with the kind of aggressive dual traction being provided from both ones electric powered wheels that one really needs on typical mountain trails;

one can literally be suddenly able to selectively carefully climb and pick ones way through potential sand, snow, loose rock, loose gravel, grass, rough fields and even climb some steep boulders also as well; for at least 25 miles to 30 miles and for about at least 3 to 3.5 hours time worry free with a decent generously sized lithium ion battery pack; now this dual purpose urban and mountain trails assault e-bike would be an absolute blast to experience riding indeed and one could definitely see how much fun it could actually be to get out on some rather grueling mountain trails that I have hiked on before previously to look forward revisiting once again using this very powerful e-biking mountain trail touring tool;

now the Easy Motion Evo Big Bud Pro has the dual wheel electric hub motor setup for $3,600; with 350 watts for the rear wheel electric hub motor and 250 watts for the front wheel electric hub motor; while the Rad Rover has its fat e-biking setup for $1,500; the Rad rover has a 750 watts for the rear wheel electric hub motor and one can rather easily as another add on optional front wheel driven 750 watts for the front wheel electric hub; for a total potential combined total power output of up to 1,500 watts in 4wd mode if needed;

so for the Rad Rover fat bike setup for $1,500 that comes with its included 750 watts rear wheel electric hub motor and let's say about $300 conservatively for the option to add the 750 watt front wheel electric hub motor from Amazon along with a Cycling Analyst 3.0; and even adding $500 for another 11.4 lithium ion battery pack mounted to a front rack mount; that is still only about $2,300 in total costs as compared to the $3,600 Easy Motion Evo Big Bud Pro; that is still a major savings in cost of just over $1,300;

now the other major thing to consider of course is the Easy Motion Evo Big Bud Pro for $3,600 is only 600 watts total combined power output for both the front and rear electric hub drive motors; while the Rad Rover fat bike setup has for just about $2,300 only has just over 1,500 watts total continuous combined power output for both the front and rear electric hub drive motors and that is not even considering what the total peak power output might actually turn out to be;

now guys the actual total cost for the modified dual drive all wheel drive customized fat e-bike setup for the Rad Rover is only $2,300(as described previously above); while still able to deliver at least 1,500 watts of total potential continuous output power to ones dual wheels on the ground thru its dual all wheel drive fat e-bike specific top quality Kenda Juggernaut tires; now with the customized fat e-bike setup described Rad Rover described above that is actually just a bit over two and a half times the total combined power output of the Easy Motion Evo Big Bud Pro dual drive all wheel drive fat e-bike setup and yet it still somehow manages to cost basically still somehow less than $1,300; holy cow that is basically a "steal of a deal";

now that is definitely a fat e-bike project that is practically basically begging to be built just for the upgrade performance cost in parts in terms relative to the cost of the basic core $1,500(about 1.5x) Rad Rover fat e-bike itself versus about 2.4x the cost of a core Rad Rover $1,500 fat e-bike; for the Easy Motion Evo Big Bud Pro turn key fat e-bike configuration; while it basically costs just about only $800 additional to performance upgrade ones Rad Rover fat e-bike with some additional upgrade parts($300 for the 750 watt front wheel hub electric motor drive and $500 for the second lithium ion battery pack); and we are not even talking about the potential doubling of the power that the Rad Rover is going to be definitely experiencing going from 750 watts on the rear wheel electric drive hub motor to another 750 watts on the front wheel drive hub motor; for heavens sake, that is another whole additional 900 watts of pure total watts of potential unmitigated continuous output power that can be potentially applied "in real life" to ones dual wheel Rad Rover fat e-bike tires and any terra firma that may yet lay beneath them to be explored on mountain trails and the like hopefully;

and yet another point for potential contention and mutual consideration; exactly how many dual wheel all wheel drive capable fat tire e-bike configuartion does one know of; that can actually provide 1,500 watts of total combined output power thru its massive dual fat e-bike tires for not more than $2,300? Tora Harris(founder of Juiced Bikes) eat your heart out we just may have in fact just taken out his very own Hyperfat fat tire e-bike still in actual product development currently having ongoing problems still trying to be developed and built successfully in their asian chinese factories; and their is a very strong distinct chance and actual "real world reality" probability possibility that this dual wheel all wheel drive customized Rad Rover fat tire e-bike design can easily beat not only the Hyperfat fat tire e-bike and but also perhaps even the original "all wheel drive" flagship design by Easy Motion Evo Big Bud Pro($3,600) quite badly on a performance specification wise basis at least also as well; and one can actually build it actually right now without any further waiting and also build it at a significant anticipated project cost savings over the projected cost of the actual HyperFat fat tire e-bike when it does actually come out and easily beat the cost of the Easy Motion Evo Big Bud Pro($3,600) also quite handily by a huge cost factor and absolutely ridiculous cost savings margin; at the same time also as well.


One horsepower equals 745.7 watts; 1,500 watts divided by 745.7 watts equals 2.01 horsepower; and guys that is only the defined rated continuous output power; as the actual peak output power is actually not 750 watts but actually 1095 watts maximum peak output power; or

1095 watts peak maximum output power times two wheels equals 2,190 watts peak maximum output power; 2190 watts divided by 745.7 watts equals 2.94hp actual total maximum peak output power in terms of rated equivalent horsepower; holy cow guys that is almost 3 horsepower peak total maximum power output in terms of rated equivalent horsepower; that would seem like more than enough to potentially beat the HyperFat fat tire e-bike at least on a paper technical specification basis; for not much more money to boot also as well(no brainer-build it and find out; no worries Cycling Analyst 3.0(Grin Technologies-they also actually sell pairs of massively heavily reinforced hardened steel(think lawn mower blade hardened reinforced tempered steel) torque arms for ones front fork-cannot be to safe they say its actually true in real life) will confirm ones actual power output is all genuine, authentic and real for "real world" confirmation and proof of actual power output in terms of maximum continuous power and maximum peak power total actual power output figures-so their will be no doubt at all if one actually somehow beats the HyperFat fat tire e-bike and/or the Easy Motion Evo Big Bud Pro fat tire e-bike; then one can go on youtube and actually go viral after proving one has beat any of the other fat tire e-bike potential competition hopefully and then go on to hopefully even extensively document this do it yourself (DIY) fat tire e-bike upgrade project on Youtube to also enable other potential hardcore fellow fat tire e-bikers to be able to put their very own custom dual wheel all wheel drive fat tire e-bike together for themselves also as well); now this fat tire e-bike would also make for the ultimate all terrain vehicle snow bike(with both ice and snow hardened steel studded equipped fat bike tires-same kind they use on bmx enduro downhill motocross snow racing tires) thanks to its highly variable customizable adjustable power output dual wheel all wheel drive fat tire e-bike drive power transmission system;

yes guys one can actually do a do-it-yourself(DIY) Rad Rover end user customized fat tire e-bike build for just about $2,300 that will definitely result in at least 1,500 watt or at least two horsepower of total potential continuous output power(2.94hp actual total maximum peak output power in terms of rated equivalent horsepower-see above actual derived calculation) being directly applied to ones dual wheels on the ground thru its dual all wheel drive fat e-bike specific top quality Kenda Juggernaut tires; now if that is actually worth $2,300 to any hard core fat tire e-biking individuals out their; please report back if anyone has built anything remotely like this previously in the past or even considering also building something along the lines of a dual wheel all wheel drive fat tire e-bike as previously extensively described and discussed above.

P.S. to Andy in Ca; it need not be a lithium ion battery pack hog; that is what the Cycling Analyst 3.0 is for; as it is being used as a programmable cycling computer, where it can supposedly set up a end user defined customized power output profile to drive ones front wheel electric hub motor drive; so one can very precisely and accurately dial in the exact end user defined power output going to the motor controller that is driving the front wheel electric hub drive motor; and yes it can actually be both varied and also adjusted on the fly in "real time" to fit ones "real world" and "real time" conditions on an as needed "user defined on demand" basis; naturally of course one can also do the same with setting up another Cycling Analyst 3.0 programmable cycling computer to also actually customize and control the actual amount of power going to the motor controller for the rear wheel electric hub drive motor also as well similar to what is going to be done in conjunction with the front wheel electric hub drive motor; also Andy the Cycling Analyst 3.0 can also if needed to conserve both power and range on ones lithium ion battery pack if needed by also being able to put a optimal end user defined maximum speed velocity threshold cutoff value if actually needed and/or also be able to additionally put a optimal end user defined maximum current threshold cutoff value if also actually needed and/or necessary to still make it to home base without potentially running out of critical potential needed power on ones lithium ion battery pack also as well in an potential unexpected emergency for example of course.

I'm not sure if this is exactly the same problem, but yesterday morning I couldn't start my Evo Big Bud Pro (have had it for 3 months). I knew the battery was 100% charged (the green led lights on the battery confirmed that as well), but the display continued to show 0% and the 0% was flashing rapidly. After numerous attempts to remove and mount the battery again, checking the cables and the contacts, reset the display, etc. etc., nothing seemed to solve the problem. I realized that I had to ride the bike unpowered all 7k to my ferry and then another 3k to the Evo store.. However, after only like 7 minutes on the bike cursing loudly the display suddenly showed 100% battery and the motors kicked in. Puh! When the store opened at 10 am I called them and explained the issue and they told me to bring it in after lunch.

At the store the service guy informed me that some of the early 2016 bikes had some kind of problem with the battery (don't ask me the details) due to a bad construction/production choice, and that the store had received information about how to fix it. It took about 45min to fix and it looks like he took the battery apart and at least glued a bit since I could notice some glue around the contact. They also adjusted something so that the battery is easier to remove and put back in, and also the key for the battery is easier to turn now. Hopefully the fix will do the trick so I won't be standing there in the morning with a "dead" bike knowing that it will be an absolute nightmare to commute to work.

As I said, I'm not sure if this is the same issue as you are experiencing, but I guess that it could happen during a ride as well.

Updated free hub overhaul guide: Since I have two motors and rear wheels, one of them just sitting in the corner, I thought I'd revisit the Dapu free hub overhaul procedure.

The magnets will suck them up and you'll never get them out.

Step 1. To make cleaning and reassembling the free hub easier, let's just lift the whole thing off the motor housing. To do this, we need to unscrew the two locknuts on the axle. Use an 18mm cone wrench or a long socket to do this. Hold the axle with a wrench on one end and unscrew the nuts one at a time. Take note of the number of shims underneath, if there are any, and set them aside. I prefer to put everything in a mineral turpentine bath.

Step 2. Now loosen the cone nut that has two notches in it. You may need a special cone nut socket for this, but I was able to use just a pair of angled pliers and slightly tapping one jaw of the pliers in the clockwise direction (left-handed thread) to loosen the cone nut. Don't unscrew it, just get it loose and back to finger tightness so you don't have to do this in Step 5. (Note: user @eiKei reports that the SuperB TB-1018 cone nut/crown race tool works a charm for this application. So any tool with similar dimensions should work).

Step 3. By removing the smaller Allen machine bolts near the free hub body, you can lift the free hub out of the motor housing. Find the correct size hex key, clean the hex holes if the key doesn't seem to fit all the way. Find a rod or punch tool to lightly tap the hex bolts before trying to open them (see optional Step 21 below). Keep tapping if they feel like they won't come loose with sensible force. You can easily strip the bolt holes with too much force!

Step 4. Lift the free hub assembly out of the motor shell by twisting it against the pawls (ratchets) and wiggling it while pulling it out. Only an O-ring between this part and the motor housing / lid is holding it in at this point.

Step 5. With the entire free hub assembly now in hand, you can try to unscrew the cone nut by rotating it with a hex key tip or similar small tool, clockwise as before. Do this on the floor or over a pan or tray, as some of the the bearings will fall out, and the free hub core will separate from the shell (splined part) and cone nut. The actual load bearing sealed bearing is on the bottom of the free hub core (inside the motor housing), and a third free hub bearing is a sealed bearing on the inside of the cone nut. This shouldn't need servicing, but you can pull it out at this point and replace it with any matching sealed bearing . Do not apply solvents or excessive cleaners on the sealed bearings, just lightly clean the exterior and remember to apply grease before assembly.


Step 6. Make note of the number of shims and their order underneath the cone nut. This stack determines the tightness of the free hub (how much the cone is allowed to press down on the bearings), and you might want to get rid of one of the thinnest ones if your free hub was loose and had some play in it.


Step 7. Drop all the ball bearings into a solvent bath (turpentine, gasoline etc.), and clean the pawls, ball bearing races and inside of the shell and ratchet teeth with towels tipped in a solvent. Do not spray the sealed bearings with a brake cleaner or immerse them in a solvent, this can dry them out and ruin them. Add only a thin coat of grease to the pawls, as they need room to operate and thick grease may prevent this. Make sure the bent end of the spring is in the notch meant for it, and that the pawls are oriented and seated correctly.

Step 8. Apply grease to the races, a grease gun helps this step immensely. Shake the cup of solvent bath you had your ball bearings in, and seat the cleaned ball bearings in the races with tweezers, first dropping the balls onto a towel and drying the solvent. There should be 27 balls on the inner (lower) race nearest to the motor housing shown here, and 26 on the outer race (inside the splined shell). The bearings are ~3.11mm in diameter, which is a common size in many standard free hubs, and you can salvage bearings from old ones should you misplace one or two in this step.





Step 9. Reassemble the free hub body. Now this is the most difficult part, and you need enough grease to hold the bearings in their races, and might need to repeat this and Step 8 a few times. Place the shims onto the free hub core axle in the right order (thickest one with a slight cut beneath). Put the cone nut into the top of the shell, and look inside to see if the bearings are still in place. Keep holding the cone nut in, and position the core of the free hub into the shell carefully, turning it slightly so the pawls will be compressed and the shell and ratchet teeth can slip past them. Don't force the pawls or they will jump out of their seats, or the spring will come out of its groove. Now, hold the parts together with the tips of your fingers and carefully turn the cone nut with a hex key or other, counter-clockwise to screw the free hub core and shell together. Tighten the cone nut with your special two tooth socket or pliers. It doesn't need to be very tight at all since the thin lock nuts on the axle will hold it together too. Rotate the free hub and listen to the pawls ratcheting (should make a decent noise) and feel if the bearings are smooth. Try to turn against the pawls a few times to see that they hold and don't slip. If the cone wont screw in, or the free hub feels loose or wrong, one or more balls fell out of their race, and you need to re-do this part.


Step 10. Clean the O-ring (motor housing cover side) and the inner side of the free hub core (that holds the load bearing sealed cartridge bearing) and the inset pit on the motor housing cover where it sits, if it has sand in it, and re-grease with a light coat of grease or oil. Greasing it will help seal water out, and it did come greased from the factory. Push the free hub back into the motor housing, turning it as you go to avoid tweaking the O-ring. This shouldn't need any force when lubed correctly. Clean any dried Loctite from the ends of each M4 hex bolt thread with your fingernail, add a drop of grease on each near the tip, and carefully** thread them in.

**Caution: when screwing in any of the bolts, if they want to start off skewed, stop, clean the tip-end of the thread again. Should the bolt start squeaking or feeling really tight even with grease, STOP, and unscrew it. You'll then need to see optional Step 23 to move forward.

Step 11. Add the shims on top the free hub sealed bearing, add some grease underneath to seal the end of the axle. Screw in the lock nuts one by one, to a sensible tightness. Grease up the gap between the free hub shell and the lock nuts to keep water and dirt out.


Step 12. Don't forget (or lose) the small lug on the end of your axle, on top of the lock nuts and cassette, that indexes the torque sensor dropout slot. Seen (poorly) above the solvent bath in Step 1.

Maybe riding it up a steep dirt hill wasn’t the best demonstration you could have done. It showed me how much your legs had to work and how tired you got, but it didn’t show me exactly what the motors were contributing to the effort. As someone with arthritic knees, that’s important.

I saw a solution for a rack, but is there something for mudguards ? I had an interest in the Volbike Yukon 750 that comes with mudguards and rack (special edition or something like that) but I was wondering for this one as, for the Montreal weather, it would be even more fun to be able to commute all year long and have fun in trails...

The battery does not need to be warm lol. Batteries create heat as they discharge. The neoprene cover would insulate that heat. Still thumbs up review though

Thanks Gary! Yeah, they are great for a wide range of people... I got into it after suffering from a knee injury but I know hard core mountain bikers who use them to build trails and Mark (the other guy in this video) has a heart condition so it's an enabler for him to ride tougher terrain without overexerting himself

Can you ride with out pedalling

Jay Starr

That's so strange to me. Electric skateboards have throttles so do electric scooters. Even electric hoverboards move forward under their own power. In fact, what electric mode of transportation _doesn't_ have a throttle other than this?

1 year ago

Not on this one, it's a Class 1 model which means pedal assist only... but there are lots of others that do have throttles. They are classified as Class 2 which means that they can't be ridden legally in quite so many areas. There is also Class 3 which offers up to 28 mph top speeds, great for commuting, also only allowed on streets and ebike paths in many places

Court what gear were you in when climbing that hill? Also great listening to Mark explain how the all-wheel-drive system works I will definitely use that in my sales technique when selling these in the future I was unaware of the eco-mode feature it was never explained to me by the manufacture and having an inside guy like Mark to explain that helps a lot.

1 year ago

I don't remember the gear but I'm sure it wasn't the lowest... filming and climbing make for quite the challenge but yeah, was great to have Mark there helping and showing how the bike rides, he's a good guy :)

Nice review Court.

Couple of corrections.
The rotors are 203/180mm.
The rear motor is very powerful and the nominal rating is very conservative.
The new console comes standard. The bike you tested had older display.

Thanks Ravi... I visit Easy Motion HQ and they let me demo these bikes for review, but it's like they aren't the final versions or something. That's a little frustrating, sorry for the misinformation :/
