Summary

  • A folding, fat tire electric bike that's approachable, stable, and off-road capable. The custom 3.3" wide tires have reflective sidewalls, puncture protection, and all-terrain tread. This is the second generation RadMini Step-Thru, and it comes standard with wide plastic fenders, integrated lights, and an adjustable suspension fork with preload and lockout
  • Only available in one frame size and one color, but the handlebar and seat height are adjustable so it can accommodate a wide range of body types. The stand-over height is very low and the folding joint is fairly narrow, so you won't bump your knee. The frame feels very solid and doesn't suffer from frame flex, but does weigh more than the high-step RadMini at 69lbs vs. 68lbs
  • Large 180mm disc brake rotors provide excellent stopping power and control, both brake levers activate the rear light for safety and cut power to the motor. RAD optimized 750 watt geared hub motor feels powerful but smooth, you can adjust the top speed down from 20mph in the settings menu. Large aluminum alloy folding pedals feel solid and sturdy, chainring guide keep your pants clean while reducing chain drops
  • Wide 11 to 34 tooth gearing makes it easy to pedal up steep hills and comfortable to maintain ~20mph top assisted speeds without feeling outpaced, large thumb shifter is intuitive but a little difficult to reach compared to triggers. The new twist throttle design feels good and overrides pedal assist at all levels for easy starts and extra power when needed. Full sized 1 amp USB charging port below display, excellent kickstand placement, wide range of compatible accessories

Written Review

To run the forums, host the website, and travel, I charge a universal service fee for my reviews. This in-depth review was sponsored by Rad Power Bikes. My goal is to be transparent and unbiased with you, this video and writeup are not meant to be an endorsement of RPB products. I welcome your corrections, additions, and feedback in the comments below and the Rad Power Bikes electric bike forums.

Observations:

  • Starting in 2020, customers in some major cities including Austin, Seattle, Sacramento, and Vancouver Canada can pay $149 to have the Rad Mobile Service van deliver, assemble, and provide maintenance support for their ebike. The company is also offering demo rides and post-purchase service, including warranty work. I got to see the van and interact with some of the Austin team members, and was impressed with this unique service that blends the predominantly online presence of Rad with a local shop feel
  • This is the 2nd generation RadMini Step-Thru product, but the 4th generation RadMini! All of the kinks have been worked out, but some of the hardware components are decidedly mid-tier to keep the price down… those include the non-locking grips, square tapered spindle, spring suspension fork with 9mm quick release vs. thru-axle, Shimano Altus derailleur, and freewheel vs. cassette. This bike also comes in a high-step version, which only comes in black and does not offer bottle cage bosses like the step-thru
  • Rad Power Bikes introduced a new metallic head tube badge, updated headlight with LED light ring and focused beam, and smoother twist throttle that foregoes an on/off toggle switch for this generation of bikes. The RadMini models moved from 20″ x 4.5″ smooth tires to slightly narrower 20″ x 3.3″ studded tires for all-terrain use. The reps I spoke with explained that the new tires are more versatile and nimble, and that the new throttle is more reliable and tends to be less confusing for riders who would occasionally turn off the original throttle by accident, and then become concerned

Pros:

  • Rad Power Bikes custom engineers their frames and puts a lot of attention into the details of which components are used… even going so far as to co-brand them with parter companies like King-Meter for the LCD display, Bafang for the hub motor, and Kenda for the tires. Note the longer seat post binder lever that Rad uses, it’s much easier to unlock and then tighten without straining fingers vs. a traditional shorter binder… though it does add a little extra weight, and also note the gray decal on top of the main tube which helps to hide shoe marks when you step over the bike
  • Rad Power Bikes really nails it with the integrated lights because they run off of the main battery, have quick disconnect points for easy replacement if damaged, and the rear light has a blinking mode as well as a bright braking mode! They’re far ahead of other similar priced products… even some higher priced ebikes!
  • Excellent headlight upgrade here, you get a bright 80 lumen beam that is focused for spotting the path, and a secondary LED ring that keeps you visible from the sides. There’s even an aluminum alloy heat sink built into the top of the headlight housing to dissipate heat! At first, I thought that it was just for show, but it’s actually metal and actually connects to the internal LED housing
  • By default, the new RadMini models come with durable plastic fenders. They’re wide enough to keep you dry (as I tested in the video review above), and they are lightweight and durable… without producing a lot of noise. I really appreciate that the company designed a rear light riser, to help boost it up above the rear fender! Furthermore, if you purchase the optional rear rack, there’s an extender cable so the light fits further back. It’s protected by the rack tubing but isn’t blocked from the sides… excellent placement
  • Overall, this ebike is very comfortable and capable. The 3.3″ wide fat tires offer a 5 to 30 PSI range and have puncture resistant casing. I’ve tested them in soft sand and mud during a trip to Mexico, after lowering the pressure to ~5 PSI, and they worked pretty well, though not as well as the full sized fat tires which are 4″ and have a larger contact patch due to the wider diameter of the wheel! The adjustable length stem and low-rise handlebar on this bike are sturdy and capable, they don’t require riders to reach or lean so far forward, which I find to be more comfortable. The spring suspension fork offers enough travel and adjustment to reduce wrist, arm, shoulder, and back pain, and the bike gets even more comfortable if you purchase the optional suspension seat post
  • Matching faux-leather ergonomic grips and saddle look great and provide good comfort. I’ve tested a bunch of seats, and this one is soft enough, but not so wide that it will chaff your inner thighs when pedaling. It also has a handle built into the back for easier folding and lifting of the bike
  • I really like the bell that’s built into the left brake lever, it’s compact and stays more protected when folding while keeping the handlebars clean, but works reliably and produces a friendly chime. I also like the rubberized brake levers, which don’t get as cold or feel as sharp as all-metal
  • Some folding bikes skip the bungee cord, magnet, or a Velcro strap to keep them from coming unfolded but the RadMini does not, it comes with a Velcro strap! You could still use your own bungee cords or get an adjustable one like this to keep the frame extra secure when transporting in a car, boat, plane, RV, etc. I often place a towel or t-shirt between the frame components when folding and transporting, to reduce scratches and chips. Some owners have purchased large plastic tubs and posted about it in the forums here
  • I like that Rad Power Bikes is using the same battery pack for all of their models now. This means you can purchase a few bikes and easily swap the packs around if you forget to charge, or decide to take two packs along for an extended adventure! The battery itself uses high-quality Samsung lithium-ion cells, is warrantied for a year, and is cheaper to replace because it doesn’t contain the bike controller. You can charge this pack on or off the bike frame, and it has three key positions for unlocked, locked to frame but powered off, and locked to frame powered-on. This helps you to deter tampering without having to take the battery pack off. For best results, store the battery in a cool, dry location. Extreme heat can damage the cells and extreme cold will stunt them and limit your range temporarily
  • Note the stainless steel torque arm on the rear left dropout that reinforces frame strength! This will keep the motor axle from chewing into the softer aluminum alloy dropout over time, which is important for such a high-powered hub motor
  • Even though the battery and controller box are mounted externally, this is a purpose-built electric bike with internally routed cables and wires (impressive for a folding model!) The black wires and controller box are more prominent on the white frame here, but still well protected based on their position and surrounding tubing
  • Many step-thru models, especially folding ones, can feel flexy if you’ve got a heavier load… but this frame uses thicker tubing and reinforcement gussets to offer 275lbs of max load capacity, and it doesn’t flex very much or suffer from speed wobble. Notice the additional tubing around the battery pack that connects the seat tube to the main tube, that really adds strength
  • Excellent weight distribution here, notice how low and centered the battery is on the bike frame, this improves stability and frees up the rear for adding a rack and cargo, I’m very impressed that they also included bottle cage bosses on the downtube
  • Both of the frame folding points (at the center of the frame and on the stem) have a locking mechanism for safety when riding, the main joint uses an extra large stainless steel clasp for durability
  • The planetary geared hub motor offers great power for starting, navigating soft terrain, and climbing. Although it ramps up steady and smooth vs. zippy, it’s still very capable and pushing the 750 watt max limit for US ebikes. You get 80 newton meters of torque, which is also at the higher end of what’s available in the legal Class 1 and Class 2 system (meaning you can ride without a license and enjoy on more trails and parks)
  • The geared hub motor is zippy and powerful, more so than the RadWagon and RadCity models, which use a gearless hub motor. The geared motor doesn’t offer regeneration and it does produce some more noise, but it’s torquey enough to power through snow and soft sand if you lower the tire PSI to the 5-10 range. The geared motors also freewheel without introducing magnetic drag, so they can pedal more easily if the motor is turned off or if you try to exceed 20mph by pedaling extra hard
  • I love the sturdy aluminum alloy folding Wellgo platform pedals (most folding ebikes use plastic that flexes), the durable alloy chain guide, and the steel derailleur guard because it means you won’t slip off as easily, won’t have the chain bouncing off, and can protect the sensitive shifter parts and motor power cable from getting bent or snagged if the bike tips, is parked at a crowded rack, or gets tossed around in shipping or when folded during transport and storage
  • In addition to the standard fenders, bottle cage mounts, and rear rack bosses, this e-bike offers sturdy front rack mounts! Rad sells a bunch of accessories that all work well together on this and other models, they’re interchangeable with some baskets working on the front and I especially like the insulated bags, waterproof panniers, and child seat option
  • I love that the LCD display panel is fairly large, has adjustable backlight brightness, and offers a full size USB charging port built into the bottom. This is very convenient if you are using the optional phone mount for GPS and need a bit of extra juice for your phone on long rides
  • For me, the three-button control pad that’s mounted near the left grip is easy to reach and simple to use. You press up or down to raise and lower assist, you press mode to cycle odometer and trip meter, you hold up to cycle current speed, average speed, and max speed, and you can hold up and mode simultaneously to activate the lights or hold down to activate walk mode. Walk mode is especially useful if you’ve got the bike loaded up with gear or a child seat and just want to play it safe without over-exerting yourself up a hill or through a technical section of terrain. Hold up and down simultaneously to get into the settings menu and adjust wheel size, top speed, and backlight brightness
  • The RadMini models use a high-resolution 12-magnet cadence sensors, which makes starting and stopping more predictable. I love that they also included motor inhibitors on both brake levers (which also activates bright mode on the rear light!) It seems like they really dialed in the controller settings too, because the motor is smooth and predictable when starting vs. delayed or jerky
  • The throttle setup on all of the Rad Power Bikes is perfect, in my opinion. It provides you with full power, anytime the bike is turned on. This means that you can zip around without pedaling in assist level zero, without worrying that you might accidentally activate assist by moving the cranks as you get on and off. It also means that you can override assist levels 1-4 with full power to climb a hill or catch up with friends… all without clicking buttons or looking down, just twist and it goes! For people who don’t want a throttle, there’s a quick disconnect cable right near the handlebar that’s easy to access, and doing this will convert the bike to Class 1, which is legal on more mountain bike trails
  • The kickstand is adjustable, has a wide platform at the bottom to keep it from sinking in to soft terrain, and it works well if you’re loading the bike with gear. Note that the kickstand is positioned far enough back that it won’t cause pedal lock when backing the bike out, or cause heel strikes when pedaling
  • I love that the optional front rack is frame-mounted so it won’t interfere with steering or tip the bike sideways when parked like fork mounted racks… but it does change how the headlight is mounted, and fixes it straight vs. turning as the bike turns
  • Both wheels are built with thicker 12 gauge spokes for increased durability and weight capacity support. I like that Rad chose to paint the spokes black on the Mini models to blend in with the rims and hubs. Note that the official max weight rating on both RadMini and RadMini step-thru is 275 pounds (~125 kilograms)
  • Great drivetrain on this ebike, Rad has chosen an 11 to 34 tooth freewheel over the conventional 14 to 28 tooth design. This provides a wider range of pedal options for easier climbing and more comfortable high-speed riding. The cogs are nickel coated, which makes them rust resistant and a lot smoother to shift. The Shimano Altus derailleur is lighter and more reliable than Tourney, but not quite as good as the Acera used on full sized Rad models like RadRover and RadCity
  • The battery slide rack uses three bolts to attach to the frame. Some of the really cheap ebikes use a mount that only has two bolts. I have found that the batteries don’t rattle much and I haven’t ever seen one come loose
  • I think the standard free shipping is a great option, and Rad Power Bikes has updated their box to include some fun artistic graphics. Note the plastic handles built into the sides of the cardboard box for easy lifting and dragging (I suggest asking a friend to help you move the box safely, because these are heavy machines)
  • It’s cool that Rad Power Bikes has expanded to Canada in recent years. They specced their motor down from 750 watts to 500 watts in order to comply with local rules. Both countries offer free shipping and Rad has offices in both locations, including shops and mobile delivery service vehicles that provide assembly and test ride options

Cons:

  • The RadMini Step-Thru only comes in one frame size, but the steering tube and seat post can telescope up for taller riders, the frame only comes in one white for the step-thru model but black is available if you opt for the high-step. Note that the high-step version of the RadMini is about the same size but has a higher stand-over height and does not have bottle cage bosses
  • The internally routed cables look nice, but they can be pinched more easily when unfolding… so be careful. Also keep an eye on the front cables when the stem is fully extended or folding and twisting the handlebar because this could pull on the some of the cables
  • The display is large and easy to read but not removable, so it could take extra weather wear and possibly get scratched at a bike rack. I appreciate that it’s well protected by the mid-rise handlebar, and that the electronics on the bike can be completely disabled by turning the key to the locked-off position (between locked-on and unlocked).
  • I love that you can enter into the display settings area and adjust units by holding the up and down buttons, but I wish there was more feedback about range and remaining battery capacity, it only shows five bars which relay 20% steps vs. 10 bars or a full 100% readout
  • Because the battery pack slides down and mounts in front of the seat tube, you may have to loosen and raise the seat post and saddle anytime you want to take it off of the bike (depending on how low you mount your saddle), this is not always the case for the full sized RadRover and RadCity models
  • The battery charger is fairly compact and lightweight, RAD says it’s reliable and works between all models, but it would be nice to have a faster charger given the higher capacity 672 watt hour battery pack… it’s another part that will be less expensive to replace, because it’s more basic, but they say it’s very reliable
  • Despite its compact size, the RadMini Step-Thru is a fairly heavy folding electric bike… most fat-tire models are! It’s slightly heavier than the high-step version (69lbs vs. 68lbs) because that one doesn’t require as many reinforcement plates and welds, it uses two smaller tubes vs. one really fat one. Anyway, I feel that they could reduce some of the weight on both models, without compromising frame integrity, by using punched-out rims vs. the solid ones we see here
  • Rad Power Bikes has been using the large Shimano SIS index shifters since the beginning, and they aren’t my favorite. You have to reach up with your thumb to press the main paddle to get to lower gears, and that can require a bit of hand flexibility and even looking down for a moment. I much prefer smaller trigger shifters, but I don’t think those will fit with the twist throttle housing, and they might not be as simple and intuitive for some riders… so I see why they stick with them, and they do work fairly well if you’ve got gloves on
  • The 180 mm mechanical disc brakes worked well during my ride test, especially with the smaller 20″ wheels, but I definitely prefer hydraulic because the levers are easier to pull and can be reach-adjusted for small or large hands, this is one part on the bike that seems to be a compromise in order to keep the price lower and the folks at Rad told me that mechanical brakes are easier for people to work on themselves vs. needing help from a shop
  • It’s great to have suspension, and I feel that Rad Power Bikes chose the best option they could for the price here, offering lockout and preload adjust. Ultimately, it’s still a pretty basic spring fork that adds a lot of weight to the frame vs. an air fork. In short, I’m glad that these mini folding fat bikes include a suspension fork, compared to the 2016 and 2017 first-generation RadMinis which used a rigid steel fork
  • Earlier RadMini products shipped with the rear rack included and it was paint matched (black or white) but starting in 2019 you had to pay $80 extra for it and it… at least they now include fenders stock, and the racks come in black or bright orange (as shown in the photographs above). Note that the same racks work for both high-step and step-thru models)
  • Minor considerations here, the headlight is mounted to the lower portion of the suspension fork and will bounce up and as a result, will bounce up and down when riding over bumpy terrain vs. if it was up on the stem, also, if you opt for a front tray rack, the headlight will have to be moved onto the base of the tray because otherwise it would collide. The thing is, the light isn’t as adjustable in this position and it no longer points where you steer because the front rack is frame mounted
  • Rad Power Bikes sells mostly online, which means that there’s some extra hassle unboxing and preparing the bike for riding, however they have partnered with some mobile bike repair services offering a $149 setup, keep in mind that the folding models are the easiest ones to get going if you do it yourself

Another great review, Court. I really appreciate when you have the opportunity to give a “real world” test ride vs. the ride around the parking lot tests. It’s interesting to hear your comments on the performance of the ride qualities and motor performance. What I admire about Rad is that they do not just make electric bikes but e-bike systems with their wide range of accessories that increases the utility of their bikes. I think it was smart to make fenders standard (except rad runner) as having to attach the rear fender has been a deal breaker for me. Now I am seriously considering a Rad Mini if my LBS will fine tune it for me.

Hi DrJay! I realize that many of the Rad Power Bike reviews have had shorter ride segments… and I actually recorded more off-road and some water fender tests, but the camera malfunctioned! Super disappointed about that. We were in a rush in terms of filming all bikes, because there was a lot of rain on the trip. I try to speak to the performance and write it here, I appreciate your encouragement!! Yeah, the RadMini models are a great combination of comfort, portability, and utility. I’d love to hear your thoughts if you decide to buy one!

EBR is a tremendous reservoir of information on E-bikes and the industry. I can imagine the logistical difficulties for you, Tyson and Mikey in scheduling trips and evaluating multiple bikes in a limited time frame. Without EBR and the Forums it is impossible to get a sense of the breadth of this industry. In my area there are no large e-bike retailers like Electric Bike Center or Crazy Lenny’s or Pedego to sample different drives and styles. Most dealers have one or two e-bikes on the floor amid their better selling acoustic bikes. So for me, EBR is essential to learning what the advantages are for different drives and bike styles. It is a way to “cut through” the slick marketing hype. In a direct to consumer marketplace, self-education is the only way to minimize the opportunities for disappointment.

  1. You mention the Velcro strap the bike comes with to hold it together when folded. Does this hold it firmly in place against stops, or do you just sort of make it tight enough. (I’d sort of prefer a firm magnetic latch.) The reason has to do with item 2. below.
  2. When held folded, is it possible to grab the bike somewhere near the hinge and roll it around on the two wheels? The bike is kind of heavy and I am thinking about the ease of rolling it between your house (or apartment) and car if you are going to another location to ride. Or even just getting out of a multi-story apartment to ground level, or into your office once there. It is sort of heavy, so it would be convenient to be able to roll it around when folded. A convenient hand-hold, plus having the wheels able to turn without binding up the pedals or something else would be nice.
  3. Are there after-market hydraulic brake lever assemblies with motor inhibitors that would be a more-or-less direct replacement for the mechanical ones the bike comes with? (I’m really sold on hydraulic brakes and would probably want to switch right away.)

Howdy! To answer your questions: I haven’t actually seen or tested their Velcro strap system, I just heard about it from the reps. The magnetic clasps are great because they keep frame tubes from colliding… but I’ve mostly seen those on lightweight non-ebikes. With such heavy tires on the RadMini models, I feel like you’d need very strong magnets, which would add a lot of weight to the bike, so I see why maybe they skipped it. As for rolling in the folded position, yeah, I think it’s possible! I’m sorry I didn’t test and show that. You’d have to roll forward so the cranks don’t turn, and probably fold with the handlebar on the outside of the fold vs. inside, so the tires are parallel. Finally, yes, I do think that it would be relatively easy to replace the mechanical brake system with hydraulic and even keep the existing rotors. Now I say “easy” here with a grain of salt, because it’s not something I’ve done or have experience with. Keep an eye out for Tektro Auriga levers, because they can be ordered with motor inhibitors just like the mechanical Aries levers used here. However, you will lose the integrated bell… I’d love to hear how that project goes for you, and you could post about it in the Rad Power Bikes forums and even search if others have already done this sort of thing ;)

I’m looking at getting this or the M2S All Terrain Scout. Any reason I should get one over the other? Or anything else I should consider at this price point?

Hi Skylar, cool name! I think M2S has more variety with their products but are a smaller company than Rad and may not be able to offer the same high level of customer support. The name probably isn’t as widely recognized, so that could also impact resale value. Otherwise, I feel that they both offer a good product :)

Hello. I’m considering this ebike, but my question is if the throttle is a variable speed throttle. Id ratter use it on mode 0 and regulate the speed according to how much I pull the throttle or mode 3 and add a boost. Thank you

Hi Fernandito! Great question. Yes, Rad does use the same variable speed twist throttle on all of their 2020 ebikes (and a slightly different version with an on/off toggle button on all of their older 2018, 2019 models. You can indeed regulate your speed solely by twisting the throttle, and note that the brake levers always override the motor for safety… even in throttle mode ;)

Am I able to put a rear passenger rack for a full sized adult weighing 120 lbs in the RadMini ST?

  Reply
Court

Hi Kevin, I have no idea on this… probably not. Most of these ebikes are rated at 250lbs or 300lbs (rider and all cargo combined) so adding a second 120lb adult passenger onto a rack that might only be rated 55lbs is really pushing it. People do all kinds of things, so whatever you choose… good luck! However, no smart company or individual will feel comfortable assuring you of something that clearly violates the recommended hardware spec because that would make them liable in the event that you or a passenger got injured due to mechanical failure :)

Hi, I am contemplating buying an e bike and thinking the Rad mini step thru might be good. I am a short female, 5’1″ do you think this would be a good match? It will be mostly used for commuting. Are there any other bikes you might recommend? Thanks for your reviews. They have really helped me to understand the bikes more.

Hi! Thanks for explaining your situation and height. Yeah, Rad Power Bikes makes one of the better products for the money… and include a lot of safety and utility features. The RadMini Step-Thru would be a good fit, the stand over and minimum saddle height are fairly low, but keep in mind that it weighs 69lbs (31.29kg). The fat tires are fairly comfortable and offer stability, and I like that they have reflective stripes and puncture protection. All things considered, it’s a good brand, and approachable bike… I think I’d just remove the battery when lifting and make sure the tires are taken care of because changing a flat is no fun ;)
