  • One of the most affordable recumbent tadpole trikes I've tested, you do have to pay an additional $350 for shipping but it comes "ready to ride" so you can hop right on
  • The 48 volt battery supports increased power and higher speeds for the 500 watt internally geared hub motor, this thing can reach ~26 mph or you can set the speed much lower using the display
  • Solid rack with pannier blockers and two bottle cage bosses on the seat frame for fluids, locks or a mini-pump, independent mechanical disc brakes from Tektro with electronic sensors and a parking brake
  • The trike is rear heavy with both the battery and motor positioned at the back but the battery is removable for charging or lightening the load, it's also not a proprietary battery so you can upgrade or replace it more easily

Written Review

In my experience there are two main kinds of three wheeled bicycles. The ones with a single wheel up front called a tricycle or delta trike and the ones with two wheels up front called a tadpole or tad for short. The Sun Seeker Eco Tad SX is the latter type which tends to steer tighter and position riders closer to the ground. As a recumbent trike, it offers a lower seating position which improves aerodynamic efficiency and for some a more relaxing ride. Getting on and off involves a bit of maneuvering, I usually back up towards the seat and reach down to either side using the front wheels as hand positions for stabilization… but once you’re seated, the bike is very stable. It’s a bicycle that only comes in one frame size but offers lots of adjustability for your leg length and seating (the canvas chair slides forward and back with adjustable struts for a more upright or reclined body position). Perhaps this is all known to you but as the most affordable entry-level electric trike I’ve covered I thought it would be nice to do a quick refresh and overview. What you get with the Sun Seeker Eco-Tad is a purpose built recumbent tadpole trike professionally converted to be electric by Electric Bike Technologies, sold through It’s a complete offering, shipping fully assembled and ready to ride. They will even customize some of it for you by request but the service doesn’t come free at $350 (for the contiguous USA). You get a trigger throttle, pedal assist, seven gears and a solid warranty here. If you’ve considered other trikes like the Eco Delta but want a sportier feel, higher top speed and more powerful motor without breaking the bank… this would be a good option to consider.

The motor offered with this trike is a 500 watt nominal internally geared hub mounted in the rear wheel. This is really the best place to put a motor because weight is shifted towards the rear as you’re propelled forward. Also, in this case the battery pack is mounted above and much of the rider’s body weight is also positioned towards the rear. You get excellent traction and the simplicity of a geared hub which tends to offer great torque while minimizing weight and no cogging drag. The motor freewheels meaning you’ll coast further and have a slightly easier time pedaling without any power assistance (in case you run out of battery or just want the exercise). One thing you don’t get is a quick release wheel or absolute silence when riding. Perhaps you can hear the motor whining a bit in the video review above. In my experience it’s more apparent to the rider than surrounding pedestrians… I commented several times on how quiet the bike was given its size and power. You can hit 26 miles per hour with this thing and that’s unique. Technically the bike is a speed pedelec but you can manually adjust the top speed using the feature rich display panel. This is a neat feature for riders who want to take it easy and maximize range. I had a blast with the trigger throttle but noticed that it didn’t work in level zero and seemed limited by the power level chosen. That means there’s a bit of extra screwing around pressing buttons sometimes and the button pad itself isn’t super easy to reach (being positioned behind the trigger throttle and right brake lever clamp).

Powering the motor and big bright display panel is a 48 volt 10 amp hour battery pack. This thing is well protected in an Aluminum shell, easy to access but fairly secure in the rear rack and convenient to slide on and off (for reduced weight or independent charging). I was told by the Electric Bike Technologies folks that the battery pack is not proprietary and I noticed that their connectors looked more standard, similar to a computer power plug. This means you can upgrade or get a replacement without spending as much money later on and without worrying about whether the company stays in business. I like that and was impressed to hear that they also spent extra time and energy programming custom battery curves into their controller to match each battery pack on offer. You get a much more accurate power indicator as a result of this and shouldn’t have that “oh crap” moment out on the trail when the battery goes from half to nearly empty on the display. This used to be a big deal with some kits, especially those with just a few LED lights indicating charge level. The whole setup here is professional and easy to work with… but it’s not perfect. The battery pack requires that you leave the key inserted and turned to “on” in order to operate the bike. That may not sound like an issue, and it’s really not so bad, but it can become annoying if you’ve got the key connected to a keychain rattling along the way. Consider a small carabiner clip or carry the key on its own. The other slight inconvenience is that the key must be completely removed in order to slide the pack off the back of the bike rack mount. If you don’t take the key out it will collide with the left side of the rack and could even get bent. I show this in the video and again… not a huge deal but it does represent one more opportunity to misplace the key. At the back of the pack is a flip out handle and underneath is the charging port. I wish it had a built-in LED light for safety, and I’d love to see a similar integrated light up front because recumbents just aren’t as visible as upright bicycles, especially at night. Perhaps an LED tail-whip flag pole add-on could be worth considering as an after market purchase? I like the 3 Amp charger, which is made from a similar Aluminum box design, because it’s durable and faster than average. This is the kind of thing you could toss into a trunk bag or panniers and always take along to extend the ride. Again, the rear rack is very solid with extra support arms and nice pannier blockers on either side. It’s not as capable as it could be if the battery were mounted separately but it’s good for what it is.

Operating the bike is a two step process with the battery charging, mounting and key insertion covered earlier followed by a control pad button press. The M button activates the display and from there you’ve got several power options and supporting stat readouts. The display itself is a monochrome LCD with lots of space to show battery level, power, odometer etc. and it’s right up in your face… at least if you look slightly to the left. Electric Bike Technologies did their best to mount this thing in a convenient spot. It’s a really beautiful display and holding the up button on the button pad will activate backlighting. I love that you can turn this completely off to avoid distraction during night rides. Following from before, you can enter the display settings to adjust top speed, current, units and several other options. This is the kind of customization that is often foregone on mainstream ebikes. Given the more sporty nature of this e-trike, I like that you get more control over how it works… The display can be swiveled to reduce glare but is otherwise not removable and that’s my one big complaint. I guess I’d be okay with a slightly smaller display if it could be removed and I’d love some sort of USB charging port for my phone but that’s just not part of the deal here. Overall, the battery works well with the display and the motor and you get a mostly durable setup. I can’t comment on how strong the display actually is and being a recumbent, it probably stays out of the way and won’t be left at bike racks all crammed together but I might carry an opaque bag or sock just to avoid unwanted attention and weather damage. It just looks so good :)

At the end of the day, this is still a converted trike. It’s not as polished or perfectly executed as the $5,000+ models I’ve ridden but in some ways it gives you more… More speed, a more open battery interface and even more options for how the bike works. This is one of the few recumbent electric trikes that lets you purposefully limit speed and power. It’s definitely one of the cheapest options but that doesn’t mean it’s not sturdy or lacking on the support side. Yes, you pay extra for shipping… you have to unless you live near Pennsylvania and can drive to their headquarters. But this is an electric bike that’s designed and assembled in America by a team with a long track record of selling kits then doing a few custom ebike projects. I admire them and love that they actually sell the electric drive system separately so you can convert your own SunSeeker trike (if you already have one). I’m more of a delta trike kind of guy because my neck has some injuries and the way-back seating position just isn’t comfortable. But it’s hard to deny the quick steering and sports-car feel of this and other tadpole trikes. There’s not fancy suspension but the canvas seat takes the edge off. The tires are average (not especially high quality or thick) but they’re all the same size so you can upgrade all at once. I like the mechanical disc brakes and thought the independent braking was cool since it can help you turn or even slide a bit and drift. It’s a neat product that would work well as a stable utility hauler during the week and a sporty racer on the weekends. Big thanks to Electric Bike Technologies for partnering with me for this review.


  • You get power on demand with a trigger throttle but the trike can also be setup for pedal assist, Electric Bike Technologies uses 12 magnet sensors which tend to be more responsive, it’s not a torque sensor so there’s a feeling of on/off but you don’t have to push hard in order to activate it
  • I was surprised to find out that the trike can be set at higher than 20 mph and used as a speed pedelec… it can also be set to lower than 20 mph for those who want to conserve power or ride in areas where high speed is not allowed
  • You can turn on backlighting for the display panel for use at night by holding the up arrow… or turn it off to reduce distraction, I like that it’s not just automatic based on the surrounding light
  • This is one of the more affordable electric recumbent trikes I’ve seen and tested, it is more of a conversion rather than purpose built but it works well and offers a lot of flexibility and options (in terms of speed and how you activate power)
  • This trike can fit a range of body trikes thanks to its adjustable boom (which the pedals connect to) and the sliding and tilting seat
  • As a tadpole trike, your body is positioned lower and steering feels very quick and nimble, it’s a bit sportier than the delta style trikes but can be trickier to mount
  • I absolutely love the cargo rack and two bottle cage mounting points on the seat frame, this gives you options for bringing along the battery charger, some extra water, a lock, mini pump and other cargo like groceries or supplies
  • The rack has pannier blockers on both sides and a mount at the back for adding a little license plate or light, I’d probably add some after market rechargeable LED lights on the front and back
  • The Promax mechanical disc brakes offer solid stopping power and work independently so you can actually brake in such a way that it helps you turn more sharply, the Promax calipers can be adjusted by hand without tools on the go using a little red plastic finger circle adjust thing
  • The rear wheel uses heavy duty 12 gauge spokes with brass eyelets to reduce rim issues like cracking, there’s also a sturdy torque arm attached to the axle which spreads force through the frame and not just the dropout
  • Both brake levers have motor inhibitor switches so you won’t be trying to stop while the motor is still running… I also like the built in parking brake on the left brake lever


  • Unless you live on the East Coast of the US and are willing to drive and pick this thing up, shipping will add another $350 to the price… though it does come fully assembled and ready to ride which is nice
  • I love how large the display is, it’s easy to see and understand, but I wish it was removable… you can swivel it to reduce glare but I’d be careful leaving it at a bike rack and maybe even cover it with a sock or something to reduce scratches
  • Being a converted ebike, there are more wires tacked on and the cadence sensor is a bit more exposed. I also felt that the drivetrain was lower quality because SunRace is an in house brand vs. Shimano or SRAM that I’ve heard of and used frequently, it all still worked well enough
  • Tadpole trikes like this are flippable, you can roll it if you’re turning on uneven terrain but overall it’s very stable when mounting and at rest
  • At ~72 lbs this isn’t the lightest ebike but it’s not terrible for a recumbent (given the extra wheel and larger frame), this trike is very rear heavy and while the battery is removable for transport or charging you still might need a little trailer to carry the bike around with your car (Harbor Freight sells affordable trailers like this)
  • In order to operate this e-trike you have to leave the key in the battery slot (which could jingle and snag if you’ve got it on a keychain, consider using little carabiners to make this key easy to separate from your main set), you also have to remove the key in order to slide the pack off because otherwise it will collide with the rack arms
  • At least for the test unit I reviewed, the trigger throttle and button pad were both on the same side (near the right grip) this made it a bit of a reach to get to the buttons and change power levels but I liked how easy the throttle was to use
  • The 48 volt battery and 500 nominal wattage motor are designed to be quick and powerful, you can still dial it down if you want but the bike is capable of sportier riding, because it’s a geared motor there’s no drag from cogging

I am surprised that with all of that space between the seat and the rear wheel, that they did not mount the battery on the frame, leaving the rear rack just for cargo.

Being rear heavy might not be such a bad thing. One thing that takes getting used to on a tadpole trike is that you can stand it up on the front wheels when braking hard, just like you can go over the handlebars on an upright bike if you slam on the front brake. It takes a bit to get used to the limits of any bike, and that extra weight in the rear might just keep your rear wheel on the ground a little more often :)

Court Rye

Yeah, I think one of the other models had a frame mounted battery like you’re describing but no rack. I believe it’s a delta so there are two wheels in the back and the seat is further back which takes up a lot of space. Another design has the battery mounted to the back of the chair in a near vertical position :)

NIRMALA: Mounting the battery to the frame is possible, but it limits your seat adjustability and makes it hard to remove the battery quickly if you need to take the battery with you (EX: if you charge the battery indoors but keep the bike in the garage). Anyway, our mechanics can do a number of things to customize your installation if you don’t want the battery on the rear rack, just call us up and we can discuss it. +1 800.375.0224

Hi Jon! Unfortunately… no, I think they only sell online. It’s one of the reasons their trikes are more affordable but you do take a risk ordering, receiving and THEN test riding vs. going in person. Very few shops around the country sell electric trikes, especially recumbents like this BUT you can sometimes find an unpowered recumbent bicycle just to see how they feel. Check on Craigslist and call your local shops :)

I recently saw a lady on an electric trike with her two little kids in the back. The trike had flags and a bright tail light for added safety. I'm not sure what brand it was but it look really cool. I think electric trikes are awesome and would be a lot of fun for people with well behaved dogs or kids.

Break -- I'm looking to do something similar. Have you gone through with the conversion? Was it difficult to install? Any thoughts on difficulties?


Hi all,

I'm going to be getting an Azub Fat trike: and I'll need an electric conversion kit with both a throttle and pedal-assist.

It seems like the best motor option for me is a 750 watt Bafang mid-drive motor. I'd like to have a torque-sensing motor, but I understand that Bafang is behind on releasing theirs, and they only have a cadence-sensing system at the moment.

I'm wondering what the difference in practice would be between a 48v and 52v battery. I also want at least a 17 amp hour battery, and if it's not too heavy, something around 20 amp hours or more would be nice.

I'm looking for suggestions on where the best place is to get the kit. And how hard would it be to install it? Should I have a shop do it, or is it easy enough to do it by one's self?

Here are the stores I know of for electric conversion kits:

Let me know what you think, thanks!

An electric tricycle is perfect for the person who would love to ride but is not quite up to a conventional bike, or trike. You can sit back and let the trike do the work or pedal when you want some exercise.It's sort of the best of both worlds.

The Electric Shopping Cruiser Any opinions?

A 250 watt hub is minimal assistance for a lightweight two wheeler. That trike is heavy. Slight boost would be noticed on level ground but there wouldn't be much energy on inclines and zip on hills, especially with a load of stuff in the basket.

If you need a trike, get one and put a stronger mid-drive kit on it.

New to the forum.
Introduction: 64 years young, male, 6'2" 280 lbs live in the Texas Hill Country.
I bought a Terratrike Allroad Rambler with BionX P350 DX20 electric assist , 24" tires about 90 days ago.
I really like the trike. However we have about 1/2 mile of a 12% increase in elevation and the electric assist just doesn't have it. What can I do to improve my situation?

3 weeks ago

I own a Fat Tad. I bought it a couple years ago, planning to convert it to electric, but haven’t gotten around to it. I’ve only put on a few miles but would be happy to answer any questions you might have.

It’s a big heavy trike, but the suspension and fat tires make for a nice, comfortable ride. Ride height isn’t very low, so ground clearance is good and getting in and out of the seat is relatively easy. I wobble when I pedal, but I assume that’ll go away with practice. I haven’t gone very fast on it yet.

It doesn’t roll though standard doorways and is heavy and awkward to carry. Im hoping it’s not too much worse when converted with the battery removed. I wouldn’t want to have to carry it twice every time I rode. I have it I my garage.

Most of the components are acceptable quality. I don’t think I’ll be swapping them out for better ones. I’m not that picky.

Overall, I’d recommend it, but it’s obviously not the right ride for everyone.

This summer I started riding my full suspension mtb along the Hennepin Canal. It's like 75 miles of basically a straight line and little elevation change. We also have a crushed rock rail trail that goes about 30 miles in a similar fashion. I'm thinking a Fat-Tad from Electric Trikes on slicks would be the perfect nature cruiser for those rides. Heads up and a relaxed position for the miles. The canal ride is so enjoyable with birds and water views the entire distance, I think the heads-up ride would let me enjoy the view better. Any opinions about the recumbent trike?

I have successfully modified a tool to pop pins out of white connectors so I can do unplanned things behind the axle nut. I put fork stiffener struts on made of aluminum angle. So I took a pick from big lots store ($2.89), and ground the tip down almost needle fine, using a bench grinder. use Safety glasses. Don't overheat. Then I could push on the tabs of the pins to flatten them, and let the pins back out of the block. When putting the pins back you have to rebend the tabs out to pop out a bit again and hook the connector body.
The reason you can't use an actual needle, they are not long enough and you need a handle to hold the needle with and apply force.Sears also used to sell a .050" thick pick in a handle. Also General Tool. The big lots one was so fat it was almost scrap to start with.
Good luck on the uncooperative vendor.

You really should not need a tool or at least we shouldn’t have to pop any pins out or remove any plug. Prior to the sale I was told specially we needed to use two torque arm kits by this company. The reason given was the cassette version of the axle was 12mm vs the freewheel version which is 14mm.

That should have been reason enough to ship the Motor without the small wires in the contacts mounted in the White Plastic Plug causing a problem for the buyer.

In addition, instructions were never sent with shipment. We were finally send an email after being told their “One Drive was down” (maybe this is there file sever), from there own company in emai, that clear states in writing on page paragraph 6, that until the motor is fitted to the Bike the White Plastic Plug should not be fitted on the contacts on the end of the electric wire, because it will prevent the Nuts and Washers from sliding off and on.

Those are not the exact words as written but I have printed the email and can scan and upload it if necessary. I am past this point unless PayPal or American Express wants it for evidence.

Point being, Motor should have been shipped end user ready from this vendor. There are a lot of first time builders out there like us. It does not mean we are stupid just because we might be inexperienced at building or converting to an E-bike/Trike at this time. This is only our first attempt. Many of us own multiple bikes s/Trikes. I personally own 5. What that means to this vendor is that by treating me poorly as he did he at least lost 4 potential future sales. Also I am not likely to say good things about this vendor to others on the forums I regularly participate in, or when I am out riding events like Ragbrai.

Lastly it should not have been assumed I was going to purchase a controller or other parts from this vendor. Motors have the capability of using various controllers. This company was told up front I was not using their controller. I will have to check my email but I believe I told them I was using a Phase Runner.

Seems there were and are enough reasons to have left that White Plastic Plug off instead of shipping the way they did.

Look at the YouTube video of an unedited ride through the rain puddles. The EFF rider screams as he gets his pants soaked. Anybody contemplating purchasing an electric trike should watch that video.

That was exactly my thought when I saw an ELF yesterday in Vancouver (nickname: Raincouver), BC.

All my e-rides have been heavily modified, and all (10+ easily, maybe even 20, since 1998) of them were working well when I either sold, gave away, or stolen.

If I owned an ELF electric trike, here's how I would mod them, for reliability:

- Install water splash shields by cutting coreplast and installing with zipties

- Make a partial floorboard of some kind. If would be a partial cover due to the components that would prevent building a complete floorboard.

- Liquid Tape in specific areas (a lot)

- Spray MG Chemicals Super Contact Cleaner where needed

- Add lockwashers on nuts

- Create a splash shield for the motor and other components underneath that are vulnerable to salt/rust

- Install two chain-cleaning wells as oil baths

- Get an air-bottle air horn

- Prevent the rubber grommets (where cables enter the ELF trike's body) from loosening, as seen on the one I saw yesterday.

For a future ELF trike re-design, or mod:

- Change to a gearless, brushless hub motor on the rear wheel, preferably a QSmotor with a matching sine-wave controller.

For those new to electric trikes: This "industry" has a history of failure. Look up the "cemetery" of electric bikes and electric trikes, at

For 10-year, daily drive durability, an ELF owner will need to do what I did to my electric rides. There are very few electric bikers in Vancouver with a working 8+ year electric rides. I still have all of my electric scooters in working order.

Wondering if anyone has or thought of leasing an E-Bike? It would be nice to use the bike for two years then either buy it out or up it

Bicycle Blue Book use local bike shops with their trade in program, it covers ebikes. All Performance Bike stores use it. If it’s in good mechanical condition you will get a certain % of what you had paid towards a new model.

I’ve also seen independent stores/chains offer their own trade in programs, locally a chain called Conte’s offers up to 40%. Some brands like Woom and Trek offer a loyalty/buy-up program on children’s bikes which seems a good way to help your child ride a bike that fits them.

If you sell privately I’ve noticed some higher end cargo ebikes hold their value, I saw a fairly new imported electric Nicola trike on sale on CL recently in my city for 2/3 of its new cost. But those are the exception, buying used ebikes you’ve gotta assume you’ll have to replace the battery.

By my math, I would have gotten less than 40% back, after I pay for all the shipping.
As it stands now, I have the trike, I will rip off all their electronic crap, bring it down to the frame, and just rebuild it somehow, as motor kits are becoming cheaper now.
It is literally just a normal trike, that was modified to become a "purpose-built electric". you can see the where they added holes to bolt in the motor and battery cage.
luckily I think I can use the same holes to mount a different motor. possibly even a gas lawn mower. turn it into a hybrid electric/gas. lol

yeah, they have my money, and it would cost me more to fight them. But I can warn others away from them, and that I can do for free!

About me:

The biggest reason for wanting an electronic bike is to help me get over hills. My price range is no more than $2,000 ($2,199 absolute max) (but not including accessories or shipping/tax). I'm 5'11", weigh 190 lbs (with a 10-15 lbs variance over time). Eventually, I'll live somewhere in the outer Boston area and will commute into Boston, (mostly on roads/sidewalks) possibly 6 - 18 miles one way (16- 36 both ways), 5 days a week. This bike will be my primary source of transportation.

I will be riding in the rain and snow. Eventually I’ll either buy or make a rain/snow shield. (which will increase drag). I’d also rather buy snow tires than a fat bike.

Features I want:

Mid-drive with throttle (prefer a trigger throttle, and that the mid-drive and throttle can handle being used together)
Class 3
Riser bar
Rear rack to be able to carry groceries and things.
Removable Display in center of handlebars
high step
Prefer a 28mph bike (the speed demon in me)
Long lasting battery (I’ll charge the battery at work, and eventually will buy a 2nd one)
Durability to handle New England weather (hot and cold temps, rain, snow)

Features I do NOT want:

Twist throttle
Half-twist throttle
Low step
Drop handlebars
Small tires
Small frame
Fat bike

What frame size should I buy? Any suggestions on which electronic bike to purchase with these guidelines? I do understand that there won't be a perfect bike for a low price. Thank you.

Based on your particular needs, I would strongly recommend taking a look at the electric trike from Priority Electric Transportation. They build a high quality etrike that is quite affordable. Call me if you have any questions.

I am a casual rider who now needs to be concerned about stability when riding. I'm in Florida and it's flat, flat, flat. I have tried riding a regular trike and find it very uncomfortable and unstable because the trike does not tilt on turns. I want the ability to bike to the store and get some power if needed.

I'm convinced a trike with 2 wheels and some type of suspension in the front will work for me, but I'm not in the market to spend $6k on a Butchers & Bicycles trike or even $2,300 on a PFIFF

Certainly, there is a source in the USA to purchase this China Made trike I have posted above or something similar. Can someone direct me to a source? Thanks in advance for the assist.

Hi all,

I'm going to be getting an Azub Fat trike: and I'll need an electric conversion kit with both a throttle and pedal-assist.

It seems like the best motor option for me is a 750 watt Bafang mid-drive motor. I'd like to have a torque-sensing motor, but I understand that Bafang is behind on releasing theirs, and they only have a cadence-sensing system at the moment.

I'm wondering what the difference in practice would be between a 48v and 52v battery. I also want at least a 17 amp hour battery, and if it's not too heavy, something around 20 amp hours or more would be nice.

I'm looking for suggestions on where the best place is to get the kit. And how hard would it be to install it? Should I have a shop do it, or is it easy enough to do it by one's self?

Here are the stores I know of for electric conversion kits:

Let me know what you think, thanks!

I have a Hilltopper 250W 24V front wheel on my 7-speed Schwinn. I don't use it for sport, just for day-to-day transportation. (I almost never use my car any more.) My terrain is flat city roads, and my typical trip is 2 to 4 miles one way.My kit has no throttle, just a push button to kick in the motor.

Most of the time I pedal in gear 5, and just use the motor for assist when I get below 10 MPH, and usually only goose myself until I'm back up to 12-14 MPH. Even pulling a bike trailer loaded with 20 pounds of groceries, I have no trouble cruising along at 12 MPH or so, although I do use the motor more when I'm fully loaded. (I'm only 150 lbs myself.) I don't need more speed than that since, at age 72, my reaction time isn't as quick as it used to be, and I find 15 MPH to be very comfortable, and 20 MPH to be a little on the "break-neck" side for me. hehe.

So as far as power is concerned, I seem to have all I need. What I'm wondering is, is there any efficiency advantage to a higher voltage, or higher power motor? Could I maybe get more range, or less battery wear by using a system that has more power than I really need, rather than pushing my 250W motor harder? I see that so many bikes use higher voltages and wattages, even when they are still topped out at 20MPH, so I assume there must be some advantage.

I'm also looking into these issues because I'm thinking about making a home-built trike just for fun, and as a better grocery-getter.

Gary-I agree with Mark's comment. You are only 150lbs and with a 250 watt motor, sounds like it is pushing you just fine. I asked the same question when purchasing my ebike. I am at 135lbs and my 350 watt motor on my ebike pushes me along at fast and furious speeds that are more than adequate. I can top out at 22.5 mph without a whole lot of exertion I asked about a 500 watt motor and they indicated it is too much power for someone in my weight class.

I like the concept of the Hilltopper. I was thinking on making one of my mtn bikes into an electric with the kit. Sounds like it is performing well! Ride safe!

I need some help finding the best electric conversion kit for my needs.

I'm probably going to end up buying a Sun Seeker Fat Tad trike, since it seems to offer the best bang for the buck when it comes to fat tire trikes for off-roading.

My questions are, what's the best electric conversion kit for this trike? And should I have it done professionally, or attempt to do it myself to save money?

So far I'm aware of the E-Bike Kit company from the EBR video on the Fat Tad e-trike. They sell a completed, ready to ride out of the box e-trike here:

And I called Utah Trikes earlier and got their pricing: Fat Tad CXS: $1,899, with 500 watt Bafang mid-drive motor: - $795, and 36v 13.5 amp hour Panasonic battery (I believe it's this one: but I'll need to confirm on Monday): $389 - Total: $3,083. And I'll need to get installation charge, and shipping pricing.

There's also a somewhat local company that could do it. I'd need to call them for specifics.

I want to get the absolute best products for the best prices that I can, so are there other recommendations for converting the Fat Tad trike to an e-trike?

Let me know, thanks!

Today I was able to try the Rad Mini, and a step-through Electra. It's not safe for me to ride a bike, at least for now. I am thinking about getting a scooter that I can go off-road with, for traveling with a truck camper though. Any thoughts on what would be good for that? Something like a scooter version of a Rad Mini might be cool.

I was able to try a Catrike Trail, non-electric version. For working out my legs, I'm strongly leaning towards getting something like the Sun Seeker Fat Tad e-trike:

I want the fat tires for off-roading, so is this the e-trike to get? Or are there competitors?

If I want it, should I get it from here:

Or should I buy a battery and motor kit elsewhere, and do a custom electric conversion?

Ideally I'd like to find a used one in excellent condition to save money. Any ideas on where these might pop up for sale? I'll ask at the Bent Rider Online forums as well.

So I'm about to pull the trigger and buy an e-bike (yay!). However, I am concerned about service. I'm OK traveling 30 or 40 miles to an e-bike shop once or twice for the initial purchase, but not basic maintenance year after year.

Do you have any suggestions for finding a local e-bike mechanic (Long Beach, CA) competent to work on (my) bike? Questions to ask, things to look for when visiting the shop, etc.? Are the differences between e- and non-e bikes small enough that skilled bike mechanics can work on everything other than the motor and battery? Does it matter in this regard whether the bike's mid-drive or hub drive? ... Sorry for all the Q's!!

Beeline bikes will come to you in their awesome mobile bike shops and fix your nonebike issues and depending on the tech some of your ebike issues. Also Southern California is the ebike capitol of the USA, do a google search and I bet you'll find a lbs that will help you. Things have have changed since I bought a recumbent trike and a ridekick power trailer. Back then I was a double heretic for the recumbent nature of my bike and the electric motor in my trailer. Now my lbs has an entire section for ebikes and recumbent and erecumbents. Is that a word?

My wife has a Liberty trike. I would not let the smaller wheels stop you from buying. It has plenty of power and is able to climb very steep hills.

One thing you do not get pedal assist, the hand throttle is how you control the electric assist. My wife has MS and the low height of the Liberty makes it easier to climb on since she has to lift one of her legs with her hands

Good luck in your search.

Have you considered electric trikes? Court has reviewed a number of them. Personally, I would go for the "tadpole" style, where there two wheels in front and one in back. The tadpole configuration is more stable in turns. (I remember as a child being thrown off my trike because I took a turn too quickly!) Yes, most of the tadpole trikes are recumbent, and that may or may not appeal to you.

i built one of these custom. (bought the bike then modified to electric) you get way less resistance in the pedaling if the bottom chain tube is below the steering rod. also, im over 6 ft tall, although the crankpost is in fact adjustable, if my seat were in your seats position, it would endo on a sudden stop. i have the bottom seat bracket (the quick release)about 6 to 10 inches further back. im almost at 1200 miles since the build. our local shop uses Shimano for powertrain on (chainrings, brake and shifter kits, derailleurs etc)sun ecos, works beautifully pedaling or throttling or both. 500w hub, 36v 12ah li-ion battery. average of 17.2 mph for 25-30 miles depending on conditions. i will mention, the promax stock brakes have a defective caliper that sun acknowledges, i wrecked them rapidly because of it, i recommend the bb5 or bb7 mechanical disc brakes, they work awesome and arent terribly pricey, and my bb5s came with the rotors included in the boxes. im digging alot of your conversions, hopefully my recommendations are useful to you. thanks for the video and the detail.

Personally I like my Terra Trike with a Magic Pie conversion. My unit lets you use the motor without any pedaling at all. I also have 24 speeds. I got my trike because I was having balance problems and with a trike I could ride instead of giving up the Electric Bike world of riding. I do have to admit I have more money invested because the trike itself is a 24 speed.

As always a good review from EBR.

I had a great idea for how to make a long range/ unlimited range solar bike. Basically you would need an e-bike with adjustable assistance to run in eco mode, two batteries that you can switch from one to the other, and a solar array, both on the bike (between the downtube and the top tube on the sides, and on a tow behind trailer. You would have to figure out the wiring, but the idea is ride in eco mode on one battery while the other one is being solar charged, then swap out. At the very least it should give you a bike that will go hundreds of miles with electric assistance, if not a theoretically infinite range

I was thinking about something and was hoping to get your input. What do you think about the Tour de France or some of these other major cycling races having an ebike support class race specifically for amateurs to get into the sport? I think that would be great to get more people into bicycle racing
11 months ago

That's a neat idea Jessa! There are many people who enjoy cycling and the fun of making new friends at events... like 5k runs. Perhaps an open or ebike specific ride would be more accessible for people like this. I know I'd be much more open to it than a hard core race :)

Why are Americans so obsessed with throttle over pedal assist and power over economy of movement that comes with a good pedal assist system. The focus on how fast you can go seems to be looking at re-inventing the car or motor bike. I have used a 250 watt pedal assist that, though cuts out at 25 kilometres/hour, allows me to comfortably pedal at 25 kph assisted by the motor. This is my car replacement and I love it. I do not feel the need to have the bicycle get up to 40 kph with a throttle. I had a moped that did that.

I should say "Gidday" as I live in Aussie Land. I have been following your videos for a couple of years now and have enjoyed them all, so keep up the good work. I've been riding a pedalec for about three years now and it has replaced the moped I used to ride. Wouldn't go back to a non-peddalec as it is too hard on my knees and the hills are too steep (Ferny Hills, Brisbane). I like the 25kph restriction as it means I am able to work myself if I want to go faster, but after riding for thirty five years I am happy to stick to the 25 limit with the motor assist. To be honest I usually only engage the motor on the hills and when I need a recovery break. I tend to use the motor like extra gears on a bike, so my range on a full charge (hub motor with 7 speed on a 20 inch) is around 100 kilometres (not pushing it) at smell the roses speed. Anyway, thanks for writing and if you ever find yourself in the land Down Under I'll be happy to show you around.

Hey Peter! Where are you from? I was born and raised in the US and have discovered that in many areas here the distance between home and any of the stores or work or school can be quiet far. This might be the cause of high-speed obsession. Maybe it's also a cultural thing with hot rods and race cars being popular here. I like that the Sun Seeker conversions (like this one here) can be set to go slower if you want. I'd rather have choice to go fast than not... even if I skip it, maybe someone else will really value it. We're not super fond of laws and regulations in the US... There's this attitude of "leave me be" which can result in some accidents and harm but also innovation and a sense of individualism. Hope this helps shed some light :)

Unfortunately here in the UK we are prohibited by the law and are only allowed up to 250W which is pathetic. There are some 'vigilantes' out there who modify their machines to over 1000W but in London aka big brother you will get caught .
11 months ago

PURE FUN! Actually, you have a good point there... I think this bike maxes out closer to 26 mph which is achievable with the drivetrain, you just pedal at a higher rate at those top speeds. You can also swap out the chainring at the front to have more teeth if you spend the majority of your time riding fast or even swap the cassette

Bottles behind the rider are useless.
I would mount it up front between my legs.
I'd also find a way to have both front brakes run off the left lever and have the rear one run off the right.
Other than that, this is seriously on my list of things to buy this year. Simplistic style and great affordability.

If leaking is a potential issue, then maybe mount it to one of (or both of) the vertical posts for the handle bars? I'm sure there would be a workaround for it.

As for using a camelback, I can'rt see them as being very comfortable when seated on this bike with a seatback. You'd be leaning back on it, thus warming the fluid with your body heat, no?

It's a shame they don't deliver to Canada.
11 months ago

Thanks for your feedback! I think this trike skipped having a rear brake at all but I'm sure one could be added with a bit of inginuity. The bottle idea is good but sometimes horizontally mounted cages let your bottle leak. I tend to use a camelbak and now they have waist packs which could be attached to the seat and sit right behind you (with the straw coming up to sip whenever you want)
