  • A funky miniaturized folding fat tire bike with two cargo racks! Truly capable of sand and snow riding, LED lights guide and keep you safe, the bike offers assist and throttle drive modes
  • Basic seven speed drivetrain from Shimano, plastic chain guide keeps things on track, metal derailleur guard protects the sensitive bits if the bike tips over to the right
  • Nice 180 mm mechanical disc brakes with e-bike specific brake levers that cut power to the system when pulled, I like the integrated bell on the left lever and rubberized front edges for comfort
  • The front rack turns as you steer the bike and if you aren't careful when parking, it can tip to the side and spill your gear out, no bungee or clasps to keep it from unfolding

Written Review

The RadMini combines two bicycle concepts that at first seem a bit opposite but ultimately pair well… Namely, a “go anywhere” fat tire bike and the “take anywhere” folding bike. What you end up with is an electric bicycle that shorter riders can enjoy more comfortably, a fat bike that’s truly sand and snow capable (as demonstrated in the video review) and a bike that will fit inside the trunk space of most SUV’s and station wagons… and even some sedans. At roughly 62 lbs this is not a light bike but you can remove the battery and front wheel easily, shaving 10+ lbs. While not as smooth riding as a full sized 26″ fat tire bike, it worked surprisingly well and I appreciated the larger chainring used in combination with the basic seven speed drivetrain. Pedaling felt natural and I loved the larger metal folding pedals by Wellgo. This is one area a lot of folding ebike skimp on, opting for flimsy less-grippy plastic. The RadMini is off-road capable but still shines on road if you’re in need of a fun commuter, perhaps a road + trail bike to get you from the city into the woods?

Powering the bike is an impressive fat-bike specific 750 watt internally geared hub motor. I say fat-bike specific because it’s wider than most planetary geared hubs I see and this allows for wider spoke mounting and thus, stronger wheels. It really does pack a punch at 750 watts, which is the maximum allowable rating for electric bicycles in the USA. But I was impressed with just how quiet it operated. Having tested this back to back with some other fat bikes using different motors, I found it to be a leader sound wise. I absolutely love that the bike can be ridden with one of five levels of pedal assist AND overridden with full power using the twist throttle at any moment. This is especially useful for getting started in soft terrain like sand. You can even use the throttle from rest in level zero and furthermore, can switch the throttle completely off. This is useful for bumpy sections where you might bear down on the grips and accidentally activate. Considering some electric bikes have trigger throttles while others have half-twist like this, it’s just nice to have that extra off switch.

The drive system, large backlit display and front headlight are all powered by a large 48 volt 11.6 amp hour battery pack. Inside are name brand, extra durable Panasonic cells that should age well if cared for properly. That is, kept in a cool dry location and topped off every month or so if not in use. This is easy to do given the removability of the battery… though it’s not as easy as some competing models. In order to get the pack off you need to insert the key, twist to the left then either remove the seat post or twist so the saddle doesn’t block the path of the up-sliding battery pack. I don’t love the battery design, especially since the keys must remain in to activate it. I noticed that it must be firmly pressed down in order to lock and once powered on, you cannot remove the keys which may jingle. Ultimately, I can appreciate that it’s mounted low and relatively center on the frame. You may leave it here and charge it this way as long as you can get the bike reasonably close to a power outlet.

Charging the bike takes around five hours from completely empty while powering it up takes just a few seconds. Twist the key, hold the power button then watch as the fixed display blinks to life. It is backlit by holding the mode and up button (which also activates the headlight). I appreciate how large and easy to read it is. Press mode again for different menu readouts or arrow up and down to navigate the five levels of assist. It would be nice to have a removable display, especially given the off-road nature of the bike. I found that even on rough terrain the frame felt solid and became curious about the rack systems. The rear rack slides out horizontally for maximum storage space (though I’m not sure what I’d put there? Perhaps a large pizza?!) and the front rack is about the size of a six pack of beverages. Note however, that if the front cargo is not secured, it may dump out as the fork turns when you park and lean the bike. Unlike some sturdier racks, it is not mounted to the head tube.

I had a blast testing this bike and came to appreciate all of the little nuances that Rad Power Bikes dialed in. You get a saddle that has an integrated handle at the back for easier positioning and folding. You get a derailleur cage to protect the sensitive bits near the rear wheel which keeps things in shape once folded. You get nice brake levers with rubberized edges and an integrated bell. The grips are a bit larger and fairly comfortable (though they may spin if you bear down since they are not locking). Keep an eye on the rear light, remember to turn it off when you stop or the batteries will run out quicker. The disc brakes are solid, fairly large and work well considering the price point. This is an electric bike that can handle rough terrain but won’t break your heart when it ultimately gets beat up and rusty if you really do go to the beach. That’s one of the trade-offs with fat ebikes specifically. Do you get the premium one that you’re afraid to ride in hazardous terrain or maybe two of the cheaper ones that you can afford to lose? Regardless of use, this one will fit those petite riders which means more people can come along for the good times. Big thanks to Rad Power Bikes for partnering with me for this review.


  • Uses a fat-bike specific hub motor which spaces the spokes out wider for improved strength, I found that it was quieter than similarly specced geared hub motors
  • I like that the bike offers both pedal assist and twist throttle mode, it’s useful to have immediate access to full power when you’re riding in sand or snow even if you don’t have assist enabled or are in a lower level… but they also included an on/off switch for the throttle so you can avoid accidentally activating it
  • The bike seems pretty tough overall, designed to handle bumpy terrain with a plastic chain guide and there’s a metal guard around the derailleur on the right in case it tips, simple black or white paint choices are easy to touch up or cover if it gets scratched
  • Neat rack system, plenty of extra space for hauling food on a picnic or tents and other gear on an adventure, the rear rack extends horizontally for increased cargo space
  • The folding design of the bike works well enough but I appreciate the extra locking clips that reduce any potential for loosening or opening while riding
  • Despite being a mid-step folding frame design, I found it to be fairly stiff and solid feeling… the double tube design definitely improves strength
  • My girlfriend isn’t especially tall but she was still able to use this bike and ride on the beach with the rest of us, stand over height is ~26.5″ but there is a wide point where the frame folds so even if you can stand over it be careful with your knees and inner legs to avoid scrapes and little bruises from this
  • If the tires are run a bit low, they add some cushion along with the ergonomic grips and comfort saddle… no suspension fork or seat post suspension on this bike but the price is pretty competitive at ~$1,500 and you could add your own basic 27.2 mm seat post suspension after market for as little as $30
  • I like the disc brakes because they don’t get as wet or dirty as rim brakes (being mounted higher) and found the brake levers to be comfortable with rubberized edges, I like that they chose the models with a bell integrated into the left grip and appreciate the integrated motor inhibitors
  • I love that the bike comes with LED lights, it’s handy that the front one is designed to run straight off the main battery… they didn’t wire in the rear because it’s further back at the end of the rack and I’m told that in flashing mode it can last quite a long time
  • Normally I dislike folding pedals because they’re shorter and less rigid than traditional platforms (being made of plastic), in this case however, the pedals are a bit larger and made from Aluminum allow so they work pretty well
  • I like that they included a slap guard on the right chainstay (to protect it from the chain bouncing and chipping it on rough terrain) and that they used a torque arm washer for the rear wheel AND that the front wheel is quick release so you can reduce weight and size further when folding if you wish
  • I love that it comes with an adjustable kickstand and that it’s mounted towards the back, out of the way of your cranks and pedals because that makes it easier to maneuver when parking


  • The front rack turns as you turn the handle bars and steer the bike, I noticed that if it’s loaded and you park the bike without stabilizing the front wheel it will tip to the side and sometimes dump your gear out
  • The RadMini uses a cadence sensor to activate pedal assist and the part only uses six magnets while some other bikes use 12, in practice it worked fine (perhaps their software is really dialed in?) but this is an area that gave me pause
  • I like how the twist throttle feels but sometimes people with smaller hands or those worried about bumpy terrain don’t like them as much as trigger throttles
  • Some folding electric bicycles have magnetic clasps or rubber bungee loops that keep the bike from coming unfolded or rattling around and scratching but this one does not, consider using your own bungee cords or an adjustable cord like this
  • While the battery is removable, you basically have to slide the seat tube out or twist the saddle sideways in order to get it off, I do like that the saddle has an integrated handle for moving the bike or working with the battery in this case
  • There are labels on the side of the tires that say “inflate to 35 PSI” but in my experience you want to hit between 5 to 30 PSI depending on terrain, go much lower towards the ~5 for soft sand or snow
  • Two step on/off process wit this bike… first you insert and twist the key (which has to be left in the battery while riding) then hold the power button on the control pad near the left grip, this takes longer and the key can jingle if you have anything connected to it
  • For a folding bike, this thing is definitely on the heavy side… as you might expect with the fat tires and racks, still worth considering (remove the battery and front wheel to reduce weight somewhat)

How does the bike fit a taller rider? I noticed in some of the video, you have the seat set very low…..were you able to dial it in for a taller rider?

Court Rye
5 months ago

Hi Nirmala, yeah the seat can go higher… it was set low in this video for my girlfriend Mony. We were all riding around the beach swapping bikes and I should have raised the seat but knew I was going to hop back onto one of the larger models so I did not. You can indeed raise the seat and there are even some extra-tall seat posts that you could buy to replace the included 320 mm post if needed. Hope this helps :)

Hi Court, I’m thinking about getting this bike for my commute to work which includes taking the T. How does the dimensions (folded) and weight of this bike compare to regular folding bikes like Dahon? The weight is almost twice as a regular folding bike but, I’m not sure about the dimensions. Do you think it would be a good option if a part of your commute is to get on a train with this folding bike?

Also, recently I came across a folding ebike from Genesis. Seems like a nice affordable ebike but, I couldn’t find any reviews on YouTube or other website. It would be nice if you can review it. Thanks, Mehdi

Hi Mehdi! I’d say there is a hug difference in both size and weight of the RadMini fat folding ebike vs. a more traditional sized folder… As a smaller, not super strong guy myself I’d probably opt for something else if I was going to take it on the train. There are lots of folding options that I have reviewed here but not the Genesis model yet. Thanks for the heads up, I’ll keep an eye out for them in the future :)

Curious. I’m 5 feet 10 inches. 200 pounds. How does this thing handle San Francisco hills?

Court Rye
5 months ago

Hey James, I didn’t climb the steepest hills in SF when I reviewed the older version but for me (a 135 lb guy) it worked fine there and surprisingly well on the sand. One advantage it has for climbing and soft terrain is the smaller diameter wheels… when used with a hub motor there’s a mechanical advantage because it’s easier to turn. The bike isn’t especially light and there is more drag from the fat tires but again, it worked fine even with the larger guys in our group on the beach :)

Love the look of this one. I live on top of a hill that’s about a 15 to 23 degree incline for about a block and a half. Based on your experience with it, how well do you think rad mini would handle that?

Court Rye
5 months ago

Hey JP! Without knowing your weight and intended cargo it’s difficult to say for sure bit I was VERY impressed with the power this little thing had, being able to ride through the sand on the beach. If you approach your hill with a bit of momentum I bet it would do fine, especially if you pedal along a little bit on the steepest part. Shouldn’t be too much work and I find that it helps the motor a lot (I often pedal along when starting from zero in sand).

This looks like something I could use for RVing. I like the idea of durability for trails and trips to market. What do you think? Also does a folding design like this lend itself to use of a small trailer, for groceries and such?

Court Rye
5 months ago

Hi Bruce! Despite the smaller wheel size, this is still a very powerful electric bike. If you could figure out how to attach a trailer (possibly using a custom mounting plate) I’m sure it would pull fine. The fat tires make it a bit more comfortable and trail-capable so it sounds like a good fit for what you’re thinking. I also like that the battery comes off (to reduce weight) because even though it folds, this is still a heavy machine ;)

Court. Keep up the good work. I’ve watched a few of your reviews, and like how comprehensive they’ve all been. I am full time RV’er and was contemplating buying a gas powered scooter or dirt bike for fun and for short hops. I’m touring the SW right now, Arizona, Colorado, Utah, and Montana, and I think this is a good fit for my situation. A RV park neighbor had two of these hanging off the back of motor home, so I decided to check them out on-line, and found your review. I do think the folding version makes sense for me, as I may want to store it inside the motor home at times, or put it in the back of my Kia Soul.

Two questions:

  • Is the full size Rad bike quicker, or does it travel farther because of the larger tires?
  • Is the folding version easier to handle in soft sand, gravel, or snow because of the smaller tires and lower center of gravity?
Court Rye
4 months ago

Cool! So glad you found my work here useful. Sounds like your friend is having a blast with their ebike and I’d be happy to help answer your questions. In my experience, the larger wheels smooth out the ride a little and might coast easier but they shouldn’t change your range much. Both the full sized RadRove and RadMini should go similar distances if they have the same motor and battery size. To extend range, it’s best to pedal along and help the bike get started vs. just juicing it from standstill. As far as soft sand goes, both the standard 26″ and smaller 20″ wheels worked well for me in the recent beach reviews. The larger wheels had a slight edge in terms of “float” because more surface area made contact with the sand due to a larger diameter (more forward and backwards contact). I’ve got footage here of both bikes in the sand and large and small riders tried both with success… just be sure to lower the air pressure to 5 to 10 PSI and note that this will reduce range due to increased drag. We still went a LONG way per charge with low PSI but it’s not as far as full tires. I think the bigger consideration is how tall you are, how comfortable the larger frame might be (as it’s higher and maybe difficult to mount if your legs aren’t super long) and also whether you want to get that thing and put it on a rack vs. packing your bike in the back of your car with the folding version. I bet the RadMini would fit in your Kia Soul. Hope this helps :D

Thanks for all the comprehensive reviews. Quick question, I’ve had problems with mechanical breaks in the past, are the breaks on radmini ok and is it possible o upgrade from mechanical to hydraulic disc brakes?

Court Rye
2 months ago

Great question Pete… my guess is that yes, you could convert to hydraulic disc brakes yourself (or with help from a shop) but I don’t think this is an upgrade that Rad Power Bikes offers themselves. Their customer service email and phone number are pretty responsive, I’d suggest reaching out directly to see what they say, and I’d love to hear back what you decide on and what the options are :D

Nice job on the fender fix. I have the fenders made for the RadMini. Other than having to fix one of the pre-drilled holes (it was off by maybe 1/8 of an inch) mine went on fine and have been solid.
Yeah I just bit the bullet for something made for the bike. I think ideally they should be included however for the price compared to many ebikes I was okay with it. It does have a nicely done cutout for the bike chain as well. I've ridden through highly flooded paths worried about splashing and possibly getting the controller or something wet but it was fine. Not sure if it would be the same story without the fenders but again I ordered them with the bike so I have no idea.

Hi @LimboJim

Here are a few follow ups to your post to help better inform customers and thank and credit you for your input:

- We recently added a sizing chart to the RadMini tech specs page and also changed the disk brake sizing for the front and rear disks to 180mm to reflect the correct production spec, as you are right the rear was still listed as 160mm on the site, but we had changed this earlier last year. https://www.radpowerbikes.com/pages/radmini-technical-specs

- Both the 500 watt and 750 watt stamped Bafang motors we have used from the start have both been mechanically equivalent, the only difference being the stamping/label on the side of the motors. After some negotiations and additional lab testing we were able to get Bafang to agree to change the stamping on the motor to reflect our 750 watt use case, until this time, they had only rated the motors to 500 watts from the factory, but we had been successfully implementing the motors at higher wattages in high volumes without issues. All Rad Power Bikes have been full 750 watts since the early days, the motor controllers power output to the motor is the true measurement, not the sticker/label on the motor.

- All battery packs use Panasonic cells. We had been using an equivalent Samsung cell in the first quarters of production but made Panasonic cells standard for supply reasons. The original weight of the packs was a little over 7 pounds and the current pack weight is 7.4 lbs (rover, city, and wagon) and 7.7 lbs (mini) mainly due to slightly heavier cells and more supporting materials used in the internal pack construction.

- Your comment about the tier of the Shimano components used on our bikes not being specified is because we have to change the specific model used in production almost on a yearly basis, since Shimano makes frequent changes to their product lines. The Shimano Acera and similar tier derailleurs and drivetrain components we use are trouble free on all the Rad bikes we run through the ringer here, and they are one of the lowest volume service/warranty parts we send to customers.

- The Front forks switched to Top Gun on all RadRovers in late 2015 if I remember correctly, will go look that date up in our BOM's.

- Wheel size on the RadMini is 20’’x 4’’ we will be on the lookout for any text that says otherwise.

- Seatpost length did get extended on all bikes. The current website specs are accurate.

- Apologies the mini was listed as a step-through, which was an error, it is more in the “mid-step” category with a 26.6’’ standover.

- The metal gears/oil bath in the original Hengtai motors were a nice improvement, but we had been testing the new Bafang fat bike hub motors in a parallel path of testing, and Bafang’s a more consistent supplier and the motors performance and durability were superb. Sorry if you did not get what you expected, but I hope that you have been happy with the Bafang motor. Most electric fat bike manufacturers followed our lead and have started adopting the same motor late last year and now in 2017 they are on a lot of bikes.

- The discrepancy in motor weight I believe was the weight of a rear wheel versus the weight of a motor.

- The spokes on all of our bikes are 12 guage.

Thanks for your comments, it helps us continue to improve and evolve, happy ebiking

i dont have as much time in on my radmini as the rover but have gotten 35-40 miles on the mini a few times

probably have 1400 miles on the rover now and i always get 40- 50 miles on my battery and this is always with 1-2 bars left
but am almost always in the flats, on good pavement and was running my tires more at 25-30 psi- have changed that and am trying 20psi because of the way the tires are wearing

get a little less mileage on gravel road rides
it is rare for the first bar to go down on my battery before 20-25 miles

mine has the controller that is controlled watts and cuts out completely when it reaches a certain speed
so level 2 cuts out at 7.5-8 mph, if i can maintain 8.5-9 etc i am peddling with no power until i hit an uphill slope

level 3 cuts out at 13.5-14 mph and once i get it to speed and can maintain 14-15 then not using any power

it is very rare for my bikes to be over 15mph unless going down a hill where it may hit 18mph for a minute - obviously under no power

think my rover has seen level 4 twice in its lifetime and never level 5

so i probably ride slower than most of you

hey dave

i like the fat tire bikes and most of mine are fat tire

have a rad rover and radmini, these are decent bikes for the price- 48 volt 750 watt - excellent customer service - replacement parts/batteries easy to get
on all the cadence sensing bikes i have ridden/owned like these the pas is not great
in my experience they all tend to be too fast in the lower levels, rad has worked on this and my bikes have an older controller that is pretty controlled in level 1 and 2

an 2016 easy motion street torque sensor 48 volt 500 watt which is my most expensive/higher end bike- excellent warranties
it is a nice bike but i do a decent amount of dirt/gravel roads and do not like the skinny tires so will be selling/trading it
it was a good deal

have a 2016 prodeco mariner folder which is a decent bike , throttle only but my lightest bike, easy to fold up and put in a car

a couple of cheap chinese bikes i bought at interbike- both 48 volt 500 watt cadence, although one has 9 levels of pas and is actually pretty good control/smoothness in pas and throttle
one is so ridiculous fast in pas i have it turned off and only use throttle on that one

and have a folding full suspension cheap mtn bike called a cemoto that was my first bike and fine but i would not buy that one again
the battery is in the frame which is a major hassle and cheap full suspension bikes are just cheap
this bike is going on 2 years old so a lot of stuff has changed battery wise etc since then

personally i am a big fan of having the throttle option, think it has a lot of good uses like being able to get the bikes home if something breaks or i get hurt somehow, especially on cadence bikes the ability to go slow is nice

this being said all my throttles act different and some seem to be touchy/wide open or off which i do not like
all my bikes are hub motors

i am looking to sell a few and get down to 4-5
most likely will buy a juiced hyper fat if the frame fits me ok, very excited for this bike to get released
also want a plus size tire mid drive yamaha or brose

at this point my riding time is limited and i am aggravated having to adjust disc brakes etc too often, would like all my bikes to be higher end with hydraulic brakes etc
since i like fat tire bikes finding 20 inch fat tires with torque sensor/throttle and hydraulic brakes is not easy, so my 20 inch fat tires/pretty much friend bikes may eventually get mid drive kits on them with those options...

just reread all this and i agree with some of the other comments, you wont be unhappy spending more money and getting a better bike
since you have a lot of hills a mid drive might be better but most of them are more expensive

i think the rad power bikes and voltbikes are good starter bikes, both companies seem to have very good customer service

hope this helps some

Nice job on the fender fix. I have the fenders made for the RadMini. Other than having to fix one of the pre-drilled holes (it was off by maybe 1/8 of an inch) mine went on fine and have been solid.

A modification I have made is for the fenders that Radpower Bikes now offers for the Radmini. Hope @mbirds knows about these now since he is a huge reason why this forum was exciting to find people who also own Radmini's and the modifications they make to them.

The modification has to do with the front fender. The back fender is solid with no rattling but I found the front fender to wobble while riding and make A LOT of noise and kind of sounded "cheap" if that makes any sense. I saw that the fender comes right up to where the light mount on the front cargo rack is which has a little indent. Will post pictures but I drilled 2 holes to slip in an included black zip tie and totally fixed the rattling and wobble that was happening which also raises the fender a bit for more tire clearance.

One issue I had also with the front fender prior to the mod was when I used the mini for fat tire trail riding purposes (so more rigorous off road riding than regular commute) I bent the thin L bracket that holds the mid portion of the fender. I ended up just forcing it back but it's definitely not L shaped anymore hah.

Hello fellow Radminites!

I just received my Radmini last week and have tinkered and adjusted a few things over the week. Now at 40 miles on the odometer. Thanks to this forum the few tweaks came easy in the settings menu at least to choose from.

I'm curious and wondering what the Everyday Carry (EDC) is for Radmini owners, ESPECIALLY those who use it for daily commute but not biased. Along with pictures of the bags, saddles, panniers, bottle carriers or whatever else you strap onto your Radmini to make it the travel mule it is. I'll post pictures soon of what I have so far, which I plan on a lot more later but essentially I have one bag that straps to the front and helps keeps the cables from protruding out so much and keeps some zip ties, the toolkit it came with, and a small towel to wipe down brakes, battery terminals, and screen when raining.

I'm using a Ibera RA5 rack on my radmini. The fat tubes of the OEM rack wouldn't fit my panniers.

these are 20 inch bikes and fat but what about the radmini or voltbike mariner
think a lot of people have put smaller tires on them like 2.5 inch wide tires if you dont want a fat bike

i know for sure the radmini does throttle from a stop- with or without pas on
and pretty sure the voltbike does too

know what you mean about the pas - even at level 1 being too fast
that was a big turnoff for me on a lot of bikes also

My Radmini should arrive in the next day. Hubby has Rad Cruiser. I test rode the Volt and liked it but opted for the Radmini for a couple reasons. Battery Volt a bit better, has dual carrier racks on front and back and the stand over. I'm short...5' 2" so the extra 8" on the stand over make a big difference for me :}. Also prefer the white vs. the black only offered by Volt. Agree that either would be a good choice but you can get $200 off when you buy two Rads at same time!!

EBR shows two reviews for the RadMini, one from April '16, the other posted in November of the same year. There are some insignificant differences, but some substantial ones as well. I'm hoping to help potential buyers find out what they're actually buying.

The more recent RadMini review says it comes with Panasonic cells in its battery, but Rad's own specs currently reflect what the April review does - Samsung cells. Both reviews show capacity at 11.6Ah, but the Samsung's weight is 1.1 lbs lighter? RadPower's Mini page also refers to the April EBR review, which makes me wonder why the November review even exists. If the earlier review was of a prototype, why does Rad still refer to it and not the more recent one?

Other differences:
Brake rotors = 180mm (Nov) vs. 160mm (Apr) - Rad's site says 180 font, 160 rear.
Wheel size = 20" (Nov) vs. 26" (Apr) - this HAS to be a mistake in Apr, clearly they're 20"!
Bike weight = 62.1 lbs (Nov) vs. 61 lbs (Apr) - 60.8 lbs on Rad's site.
Motor Weight = 12 lbs (Nov) vs. 8 lbs (Apr) - not shown on Rad's site, but 4 lbs. difference?
Seatpost Length = 320mm (Nov) vs. 266mm (Apr) - not specified on Rad's page.
Spokes = 13 Gauge (Nov) vs. 12 Gauge (Apr) - Rad's site says 11 Gauge.
Frame Type = Step-thru (Nov) vs. Mid-step (Apr) - clearly it's not a step-thru!

There are more variations (like worldwide availability vs. just US and Canada), but I digress... My late-2015 RadRover hyped a 750W Hengtai metal-geared motor on Rad's site at the time, but came with a Bafang with plastic-gears that was clearly stamped as 500W. Rad claimed it switched to Bafang for reliability and tuned the system for 750,* but the bike really struggled on hills, and I felt duped.

Additionally, my Rover came with a flimsy, no-name suspension fork. Another EBR forum member posted how his Rover's generic fork collapsed and Rad sent him a Top Gun brand fork to replace it - apparently newer Rovers now come with the branded fork. I proactively purchased the Top Gun from Rad but still sold my Rover at a loss 6 months and ~200 miles later, offering full disclosure to someone who just wanted to ride around his mostly flat neighborhood.

Rad still seems to be pretty "fluid" in its specification listings, not stating what brand fork or which Shimano gearing components they're equipping their bikes with, etc. This might allow for flexibility, but the Tourney derailleur specified in both EBR reviews is Shimano's low-end offering and won't hold up long, just like their original forks. Rad also doesn't specify the brand of motor - they clearly dropped Hangtai for Bafang in late 2015... who's to say they'll keep using Bafang?

Despite my obvious misgivings, I believe that Rad Power Bikes offers decent value for the money and has many happy customers, but urge potential buyers to be aware of possible inconsistencies between the specs shown on EBR's reviews and what you might get.

* Quote from RadPower email addressing my complaint: "The stamping on the motor, and the continuous power rating are largely unrelated since we program our controllers to provide a 750 watt continuous output power..."

Hi everyone, I received my RadMini a couple weeks ago but finally got the fenders so the bike is now complete, at least for now...
I added a BodyFloat seat post, Garmin Explore 1000 GPS, Dinotte lights, Spank Oozy Trail Platform Pedals, Zydek cargo bag, Mountain Mirrycle Mirrors, Kenda Sunlite XL Cruiser Tires, 20 x 4-1/4, and fenders. The lights and GPS I transferred from another bike.
So far, the bike performs beautifully!!

I was able to find a rear rack that accommodates the 20x4 tire size and has similar mounting brackets. It cost me $60 along with $18 for installation at my local bike store. The advantage of this rack over the original is that the tubes themselves are not as wide, so you can actually use standard bags/panniers on your rack without relying on velcro or zipties. Another nice thing is that the bags can be placed further back so you are less likely to hit your foot on a bag/pannier.

I also found front and rear fenders that could be cut and molded to fit the Radmini. I bought the front and rear for about $44 total. I think the fenders look a bit funky but $44 is much cheaper than the ~$150 for the fenders Rad Power Bikes sell, and I'll take funky over an empty wallet.

If you know any cheaper 3rd party rear rack/fender solutions for the Radmini, please post here, this is the best I've found so far.

I've seen/ridden a RadMini but I've lost the folded measurements I took. The 37"x30"x23" measurements given on the website seem larger than I remember. Could someone put a tape to their FOLDED mini? Would it's folded size be smaller without the front rack? Thanks

Thanks Cnugget. There was an ad on here for two nearly new Mariners in my area (Raleigh NC); $2K for both but I missed the opportunity. I was thinking about splitting the difference and getting the Radmini for me and the Mariner for my wife; then I could really do a comparison.

Haha.. Now that would be a worthy video and I would watch. :)

Some things are hard to tell until you get on them. Looks like the bike has had some new updates... Hopefully it's all good. I wasn't sure if I would use an ebike at all. My bow and I decided it would be better to have two bikes at ~3,000 instead of just one.. It is a great cheap date and we have fun saving the money and commuting. It is a good launcher into the world of ebikes.. I don't expect it to last forever nor compete with some of the other amazing things out there but happy so far.. but that is just me. Good luck with your purchase. Rad or Volt or whatever.. May it be fun and give you lots of grins and chuckles.

Don't forget accessories will cost ya as well.. I've probably dropped about $500 on stuff for the bike since I've picked it up. It's a can of worms so save some dollars for that too.. :D

Mariner.. but I am biased. :D I don't have the most recent upgrades they have done to the Mariner. Never tried a RadMini.
Easier to fold/lift. If you can at all test drive them, I recommend it.

Are you using 20x4 tubes? I was wondering if you have to get 20x4.25 tubes for 20x4.25 tires? I'm going to order those tires for my street riding and didn't know if I should order tubes too.

I'm using the tubes that came with my RadMini (20x4)

For spare tubes, I purchased Mongoose 20x4 tubes from amazon

For future reference, when others start contemplating swapping out the freewheels on their Radrover, Radmini or other electric bikes with similar wiring. On the left is an old Shimano freewheel tool I got years ago with a 10mm opening (same as Park), and on the right is the DNP epoch tool with an ~18.5mm opening. So no drilling or grinding necessary to get around the wheel hub motor wire connector. Thanks for finding it.

Edit: Oh shi.... still isn't going to work. Here's something I totally forgot to account for, the nut that's holding the wheel to the frame. That nut is also in the way like the connector. At the widest point, it's 20.5 mm so there is no way to pass through that freewheel tool. Maybe with some strategic grinding on the tool for 6 corners of the nut, and a little touchup on corners of the nut itself (about .5mm). Still might be possible.

Ok, I ended up splitting the tool. Wasn't too bad with a Dremel tool plus fiber reinforced-cutoff-wheel. At least the DNP tool is easier to split than the Park tool, thinner walls. I'll see how it goes this weekend when I take off the rear wheel from the bike.

Ok, so maybe I hadn't rode a bike for a year or so before I got my RadMini. And maybe I don't know the correct seat sizing / setting for this type of bike. In any event, until just now it was very difficult for me to get on and off the bike, and to stop and start the bike. Going back to when it arrived, after assembly I got on and almost messed up my knees trying to pedal the bike. The seat was all the way down, and my knees were bent like crazy. Ah yes, "When the pedal is almost down and the leg is at its furthest extension, the knees should just be slightly bent". I fiddled with the height of the seat, and set it. Nice - lots of power when pedaling, and very comfortable. But, with that seat rising up in the air so high, I was either going to need a ladder, or was going to have to lean the bike almost flat to get on and off. And when I went to stop, my feet did not reach the ground, so I was forced to jump forward and straddle the bike (I have fallen a couple times though). I learned to live with it, but was not happy. So today, I decided to revisit the seat height. I lowered it so I could touch the ground with my toes, or lean slightly and put my foot down. Pedaling was not quite as powerful as before, but I think it is close (I wouldn't win any races before anyway). My knees feel the extra bending a bit, but I think will be fine. All in all, a completely different and I think better and safer experience.

Cassette removal tool I just remembered I had in the bottom of my bike tools

I've used it on my older bikes, wondering how it would work on the RadRover & RadMini...

From the article, it looks like there are a few other touring style freewheel lockring removal tools:

Found one on Amazon: Stein Mini Cassette Lockring driver 30+ bucks


Damn, I totally forgot about those types of tools. Just the ticket for those with the wire in the axle. Well done!
