  • An approachable, comfortable, and relatively affordable, city style electric bicycle that comes in one frame size, two colors, has an adjustable stem, swept-back handlebar, and suspension fork with lockout adjust
  • Ready for all sorts of ride conditions and applications with full-coverage plastic fenders, integrated LED lights (including a brake light that goes bright), reflective tires, sturdy rear rack, and large mechanical disc brakes
  • Twist throttle provides instant power as well as safety because it features an on/off button, pedal assist is responsive and the motor ramps up smoothly, this drive system offers regenerative braking to reduce brake pad wear and recapture some energy on long descents
  • Mechanical disc brakes require more hand strength than hydraulic would and the levers don't offer adjustable reach, gearless motors tend to be durable and quiet but weigh more and produce some magnetic drag, RAD sells direct but has partnered with some mobile bike shops and has excellent customer service from what I've seen

Written Review

To run the forums, host the website, and travel, I charge a universal service fee for my reviews. This review was sponsored by Rad Power Bikes. My goal is to be transparent and unbiased, this video and written review are not meant to be an endorsement of RAD products.

The RadCity Step-Thru is an approachable, value-priced electric bicycle, built for urban landscapes. Its full length plastic fenders, reliable drivetrain, sturdy custom rack, and integrated lights make it a capable choice. It holds up well in varied weather and functions safely and reliably whether you’re commuting daily, running occasional errands, or simply riding for pleasure. Co-branded tires feature puncture protection and reflective sidewall stripes. Both brake levers had motor inhibitors and activate the back light in bright mode to generate awareness. The battery pack is cross compatible with most 2018/2019 products (except the RadBurro), there’s a healthy offering of accessories that are guaranteed to fit, and the company provides leading customer service based on what I have seen and heard from actual customers. RAD is based in Seattle Washington, USA with two new locations for 2019 including Canada and the Netherlands (though I am not sure the RadCity Step-Thru is available in Europe). These three flagships stores provide test ride opportunities, but most sales are done online with products shipped direct. This helps to keep costs down, but introduces some unboxing, light assembly, and indirect post-purchase support. Rad Power Bikes has partnered with a number of mobile bike repair services, such as Velofix, to address this. Priced at roughly $1.6k, this is still a great deal from my perspective, and most competing products have also seen a price jump. By choosing the RadCity verses one of the trail bikes (RadRover or RadMini), you’re gaining some efficiency. The Step-Thru model offers a very low stand-over height, making it easy to approach and mount. The seat tube is cut short, allowing the saddle to go low enough that many riders will be able to sit and touch the ground without going on to tip toes. This particular model only comes in one size, but RAD sells the high-step RadCity in two sizes (one the same, and one slightly larger). For 2019, the’ve introduced a second color option for the step-thru, which only came in white before. All models offer adjustable angle stem, swept back handlebars for an upright relaxed body position, and adjustable suspension fork. I found the faux leather saddle and grips to be comfortable beautifully matched. Slightly larger 2.3″ wide tires further increase comfort, stability, and add traction with a light checkered pattern. There’s a lot to celebrate with this ebike, but much of my own excitement comes from the value price point. You don’t get hydraulic disc brakes, which would be easier to pull, the bike is heavier than average at 65lbs (not a dealbreaker when you consider the fenders, rack, lights), the two amp charger is slow and steady vs. many three and four amp chargers, and the drivetrain is limited to seven speeds. This last point is a lot less relevant with the upgraded 11-34 tooth cassette (compared to 14-28 tooth before). Almost every compromise I found on this ebike had a purpose. For example, the larger cheaper thumb shifter was chosen to make room for the throttle housing and on/off switch. Many little things stand out when you really look close. Bottle cage bosses added to the downtube… high up, so you won’t kick the accessory. A faster 1 amp USB port on the display, so you can power a range of portable electronics on the go. Updated brake caliper mount position to reduce rack crowding and conical washers that are easier to adjust for brake rub. There’s a lot to say about this product, and I’ve gone especially deep with the video and writeup here because RAD sells a lot of bikes, they’ve become one of the biggest brands in the ebike space. I welcome your feedback and input in the comment section at the end of this review :)

Driving this ebike is a a Shengyi gearless hub motor that weighs about 10.2lbs and is spoked into a sturdy double-wall Weinmann rim with extra-thick 12 gauge spokes. I hadn’t heard of this brand before reviewing some of the earlier first-generation Rad Power Bikes, but it seems to be working well year after year. Gearless motors need to be larger, and are usually heavier than geared, because they produce power through electromagnetic staters and rare earth magnets pushing against each other. This, compared with a geared motor that uses a faster-spinning motor that is geared down for power through planetary gears. With a gearless motor, the further out those magnets are, the more leverage the staters benefit from when repelling. This is why the gearless motor is physically larger, having a wider diameter. The advantages to this type of motor are that you don’t have plastic gears rubbing against each other to produce power, making it quiet and more durable over the long run. The magnets and staters don’t actually touch, so propulsion is smooth and quiet. However, when the motor is finished pushing, it also drags a bit because there is no freewheel mechanism. RAD and other ebike companies that use gearless direct drive motors has designed their controller to recapture some of this magnetic drag as electricity for regeneration. The bike has regenerative braking that activates even more strongly when either brake lever is pulled, capturing up to 250 watts (which is stabilized by their controller, shown in the video around 16:23). This function combines with instant motor cutoff, for safety. To keep the axle from rocking back and forth, damaging the aluminum alloy frame droputs, RAD has implemented a steel torque arm on the left side of the frame, and this is an important feature in my opinion. Rad Power Bikes built a reputation around higher powered electric bicycles, starting with their fat tire off-road RadRover model. It’s nice to see them carrying the thicker spokes, torque arms, and motor inhibitors over to their city bikes as well. And, it’s relevant, given the high power rating of 750 watts nominal output here. Peak torque output was estimated at 40 newton meters, a bit lower than the geared hub motors rated at 80Nm. In short, this motor is quiet, tough, and very capable of transporting heavy loads and climbing moderate hills, as long as you have some speed going in. It can take a moment to start from zero without help, but it feels smooth and responsive in pedal assist mode, thanks to the upgraded 12-magnet cadence sensor, and zippy when using the twist throttle. Now that RAD has switched to a wider 11-34 tooth cassette, climbing is a lot easier, so you won’t strain your knees. Compare 28 tooth as the lowest gear in previous versions to 43 tooth here, and you can start to see how a slower cadence and improved mechanical advantage translates to easier starts and climbs. I also want to call out and compliment the slap guard and alloy chainring guide that RAD has chosen. These little upgrades will protect the frame, reduce the possibility of chain drops, and help to keep your pant or dress leg from getting greasy or snagged. The large alloy pedals provide a stiff stable platform, and won’t be as slippery as plastic or rubber.

Compared to the first generation of Rad Power Bikes, the current generation battery pack offers ~20% higher capacity and only weighs 0.5 lbs more. It allows you to go further, use the throttle or higher levels of assist without as much range anxiety, and is cross compatible with most RAD models dating back to 2018. This custom pack mounts securely to a plastic track that’s attached to the seat tube with three bolts, and secures with a keyed locking core. Notice how the battery is positioned at the center of the frame at a low point for improved balance and bike handling. It’s protected on both sides by additional aluminum tubing, which double as a frame support – reducing frame flex. The battery pack has two fuses built in for safety, and is physically separate from the motor controller. Notice the little black box behind the seat tube, that’s the controller unit. I was told that separating it out reduces heat exposure and makes replacement batteries less expensive. At $550 per pack, you get a lot of bang for your buck here compared with $800+ for many competing offerings from leaders like Bosch, Yamaha, Shimano, Brose, and others. I like the physical design of this battery, being smooth and rounded, though it does not include a handle or loop for easy lifting and carrying. Since the battery is more of a short thick design, it’s likely easier to stuff into trunk bags, panniers, and backpacks for extended rides than a squared rectangular brick. Many competing cruiser step-thru ebikes utilize a rear rack mounted battery which isn’t as sleek, balanced, or transportable in my opinion. The trade-off with Rad’s two-box solution is aesthetics, but they blend in very nicely if you opt for the black frame. Rated at 48 volts and 14 amp hours, this pack offers a total of 672 watt hours, which is above average for this generation of ebike batteries. And, I’m told that it contains high quality Samsung 35E high capacity lithium-ion cells. The battery casing has an LED charge level indicator built into the top edge, allowing you to determine roughly how full it is whether it’s on the bike or not, and you can charge the pack while mounted or separated from the RadMini frame. The battery powers the backlit LCD display panel and both lights, which is another upgrade from previous models. The rear light used to run off of two AA batteries, which was easier to forget and leave on after rides while also producing more waste. To maximize the lifespan of this and other lithium-ion battery packs, I’ve been taught to store them in a cool dry location and avoid complete discharge. In fact, it’s best to stay between 20% and 80% and aim for 50% if you know you won’t be riding for an extended period of time.

Once the battery pack is mounted and locked, simply hold the mode button located at the center of the control pad, which is mounted within reach of the left grip. The large grayscale LCD unit blinks to life showing your battery level, odometer, current speed, assist level (starting in 1 by default), and watts being used. You can cycle from odometer to trip distance by tapping the mode button, cycle from current speed to average and max speed by holding the up arrow, activate the lights by holding up and mode simultaneously, and initiate walk mode by holding the down arrow. Walk mode is especially useful if the bike is loaded with gear, if you’re crossing a park where it’s not appropriate to ride, or perhaps the terrain is too steep and unstable for comfort. Another scenario is if you got a flat tire and had to limp home, trying not to damage the tires and rims. With the upgraded Kenda puncture resistant tires, hopefully you won’t end up in a flat-tire situation too often. For those who want to adjust more settings on the display, hold the up and down arrows simultaneously. This allows you to change the wheel size, backlit brightness (1-3), and units (mph or km/h). Press mode to navigate through the settings menus and hold mode to exit settings. Finally, the most common interaction with the display is to press up or down to navigate through 0-5 pedal assist levels. The higher the level, the more power and speed you’ll get, but you can always override the current level by activating the half-grip twist throttle on the right. And, I love that RAD has included an on/off button for the throttle! This, combined with the brake lever motor inhibitors, provides maximum control over all modes of operation. The bike is enjoyable to ride and the drive system offers full control so you don’t have to compromise or limit yourself. Throttles can be useful when starting out from traffic signals or gaining momentum in soft terrain. Not all ebikes have them, but that does make this a Class 2 product vs. Class 1, which is allowed in more environments (mountain bike trails). Even though the display panel is now branded as Rad Power Bikes, it is actually a very common SW-LCD from King Meter; the same display used on many prior models (in case you wish to look it up). Rad Power Bikes has a great video overview of their display here, but it doesn’t go quite as deep as I’ve described above. I love that the company has included a full sized USB Type-A port built into the base of the display with high output, as mentioned earlier. The display can be swiveled forward and back to reduce glare if you don’t over-tighten the clamp, but it is not easily removable. Given the positioning, above the stem at the cent of the handlebar, this display should be fairly well protected from scratches at bike racks and tips, but it will still take sun and weather damage over time. Just like the rest of the electronics here, this display is water resistant, and I noticed that RAD opted for a nicer threaded connector point for the display while other connections are plastic press fit. I was told that the this and other parts can be replaced through the company, and are warrantied for one year as a part of the comprehensive warranty. I’ve noticed that some owners will secure their helmets over the display and others will use plastic bags for protect against heavy rain and snow. Just make sure to air them out because a sealed bag could result in condensation inside the display when ambient temperatures rise! Anyway, I really like being able to activate the the lights through the display, being able to adjust backlighting there, and having the ability to change the rear light from off or solid to blinking mode. To accomplish this last function, you actually have to reach down and press a little rubber button on the lower left edge of the rear light, once it’s activated. This step cannot be completed through the display. Most ebikes I see only offer lights off or solid on, but a blinking rear light can generate more awareness and is a unique upgrade. It’s something we see on most aftermarket lights, but very few integrated ebike lighting systems. Note that both brake levers have motor inhibitor switches built in to safely disabling the motor when you want to stop but now they also activate the rear light! This works even when lights have not been turned on through the display. Finally, the headlight has a light sensor built into the back, so it goes extra bright when riding during the daytime and dims slightly when it’s very dark out. Both lights are designed to be re-mounted to racks if you purchase them aftermarket, and Rad Power Bikes includes extender cables to make it easy. Note that if you do get a front rack and reposition the light, it will no longer point where you steer, because the rack is frame mounted for extra strength.

The RadMini Step-Thru is an exciting electric bike for me because it’s so approachable. People who might have struggled with hills, felt concern about arriving to work sweaty, or been left behind when riding with friends or partners… people who might have know about ebikes but struggled to find one that was approachable and well balanced, now have a great option. It’s priced well, looks great (especially with the two colors and upgraded graphics), and should perform reliably. Compared to many other wave style step-thru models, this one does not flex as much. RAD designed the downtube to be extra thick, have a gusset plate reinforcing the head tube connection point and added the extra tubing near the bottom. I was told that this and other RAD bikes can officially support up to 275lbs of capacity, and I’ve seen them handle even more. This model is being used by some delivery companies now, to transport food around crowded city environments efficiently. With its adjustable seating position, handlebar, and suspension fork, it’s a bike that could be used for rentals or shared within a family. I was told that the rear rack is Yepp! child seat compatible straight away, no adapter required, and got to see one of the optional seat post suspension accessory upgrades. This is something I have enjoyed on other ebikes, because it offers an even more comfortable “full suspension” feel, without the higher cost. Keep in mind however, the addition of a suspension post will raise the minimum saddle height by a few inches. Other quick callouts are the steel derailleur guard, which protects the drivetrain and motor power cable on the right side of the rear wheel, the quick release front wheel, and the bell that is built into the left brake lever for friendly signaling. As always, I welcome your input and feedback in the comments and invite you to participate in the EBR Rad Power Bikes Forum here, sharing pictures or videos of your own and making some friends :)


  • The cadence sensor uses 12 magnets for quick starts and stops in pedal assist mode, the brake levers both have motor inhibitors built-in to cut power instantly when stopping and now they also activate the back light in bright mode to keep you safer, the rear light also has a flashing mode if you press the little rubberized button on the bottom
  • All of the new Rad Power Bikes share a mounting interface on the head tube for adding a porteur rack, you can add a small or large basket and cargo on this platform which won’t tip when you steer or park the bike, note that the rack accessory comes with an extension adapter for the headlight
  • You shouldn’t have any issues with the chain falling off of this e-bike thanks to the durable Aluminum alloy chain guide, it doubles as a bash guard and pant/dress protector as you pedal, and the tubing that surrounds the battery pack also clears pants/dresses so it’s almost like a full chain protector, I also like the large grippy pedals that they chose vs. flexy plastic or narrow cage style
  • The step-thru frame only comes in one size but features an adjustable-angle stem to bring the handlebar up and back, note that the bar is also swept back so there’s better comfort and more versatility here than a lot of other ebikes, RPB also makes two sizes of the high-step RadCity model which could fit taller riders or those looking for more frame stiffness, lighter weight (by ~2 lbs), and easier mounting on hang style racks
  • RAD updated the logos and paint job on their electric bikes for 2019, which looks pretty good to me, I like how they added gray chevrons along the top tube to hide any shoe scuffs that might appear as you stop over the frame, this is especially relevant on the white frame and is a clever stylish solution
  • Another cool upgrade is the use of conical washers for the disc brake caliper which makes adjustment easier (to reduce brake rub), and they re-positioned the calipers to stay clear of the rack and any pannier bags you might add
  • One of the major highlights across the entire range of RAD bikes for 2019 is an upgraded drivetrain, moving from 14-28 tooth to 11-34 tooth for easier climbing and more comfortable high-speed pedaling, they’ve also moved to nickel plated cogs which are durable and environmentally friendly to manufacture
  • I was told that the adjustable angle stem has been custom made to stay tight and uses hardened materials that won’t dull as easily as some competing parts, for those with back and neck sensitivity RPB sells an optional suspension seat post, another small detail is the gnarled hardware used for the front headlight mount that keeps it from slipping side to side
  • I love that Rad Power Bikes managed to squeeze in some bottle cage bosses on the high-step and step-thru frames, and that they positioned them high on the main tube which is less likely to get kicked or impede your pedaling! this attachment point could also work for folding locks, mini pumps, or other accessories
  • The RadCity Step-Thru comes with 26″ x 2.3″ tires that were custom designed with Kenda to offer reflective stripes and puncture protection, they feel pretty comfortable and offer all-terrain traction with a checkerboard pattern so you can cut across gravel paths without feeling unstable
  • Instead of opting for the cheapest suspension fork they could find, RAD picked one with lockout and preload adjust so you can optimize efficiency and dial it in to your body weight, pre-loading the spring if you weigh more or have a heavy load
  • It’s a little thing, but the kickstand is positioned well and has a wider foot so it won’t get in the way and won’t sink into soft ground, I also like the little handle that is built into the saddle which makes lifting and maneuvering the bike easier
  • Rad Power Bikes sells a great range of optional accessories that are guaranteed to fit their bikes and look great, for the RadCity Step-Thru you can choose from a small or large metal basket, small panniers, an extra-bright RAD rear LED light that attaches to the seat post, the SR Suntour NCX suspension seat post, and a handlebar phone mount, their rear rack is Yepp! child seat compatible and has standard gauge pannier hangers for third party bags that click on and bungee loop rods towards the bottom
  • If you do get that phone mount, or use one of your own, you can charge all sorts of portable electronics directly from the display panel thanks to a USB Type A port integrated near the bottom, this port puts out 5 volts at 1 amp directly from the battery pack, which is enough to maintain and charge most devices… many competitors only offer 1/2 an amp output
  • I love that the battery pack is mounted to the frame with three bolts vs. just two and that the power cable running to the hub motor is really tucked in and well protected at the back
  • The new battery design is sleek, offers 20% higher capacity than the first generation of products (and more than many competing current gen products), while only weighing 0.7 pounds more, and does not have an integrated on/off button that you have to press before each ride, you don’t have to leave the keys in like some packs, and it has two fuses built in for safety
  • Rad Power Bikes offers free shipping if you don’t mind a bit of setup work yourself and and they’ve built a partnership with mobile bike repair venders who will deliver, assemble, and repair the product for $100, it’s a neat service for those who don’t want to deal with a big box, weight, and complexity of setting up an e-bike (but this service may not be available everywhere)
  • Gearless hub motors tend to be very durable and quiet, you don’t get as much torque and raw power at low speeds and there is some magnetic drag when coasting, but the RadCity recaptures a bit of energy when braking which reduces wear on the brake pads and might extend your range just a bit, I like that they mounted the motor with a stainless steel torque arm to keep the dropouts from getting bent over time given the weight and power in use here
  • Both wheels are built with thicker 12 gauge spokes and sturdy Weinmann rims to handle the additional weight of cargo or heavy riders, it’s rated to carry up to 275lbs
  • So many wave style step-thru electric bikes have opted for rear-rack mounted batteries which raise weight and impact steering and handling so I LOVE that the RadCity Step-Thru mounted their battery near the middle of the frame and even reinforced it with a gusset near the head tube and extra bar near the base to reduce frame flex
  • I was amazed by how low the saddle could go, it fits between the rear rack stays and allows riders who want to maximize stability and safety to put their feet down at all times, note that the optional seat post suspension will raise this minimum saddle height but two or three inches


  • The drivetrain on this electric bike offers seven gears, which is on the lower side, but the Shimano Acera derailleur is two steps up from base level and RAD upgraded the cassette from 14-28 to 11-34 tooth so the range is much better (for easier climbing and more comfortable high-speed pedaling), I feel that the addition of throttle mode kind of makes up for the seven gears whereas many other city bikes offer nine or eleven gears but only pedal assist
  • If you decide to add the front rack, it’s great that the headlight can be repositioned on the bottom (for maximum exposure) but it will no longer point where you steer because the rack is frame mounted
  • The RadWagon and RadCity models aren’t as capable at climbing steep hills as some of the new mid-drive ebikes, the motor doesn’t operate as efficiently or provide the same range potential because it’s not being run through your gears… but very few mid-drives offer throttle operation, this gearless hub motor is more smooth and quiet but offers a lot less torque from standstill and for climbing than even the RadMini and RadRover because they use geared hubs
  • I’m mixed on the brakes for this bike, the 180mm rotors provide good leverage but you cannot adjust the brake lever reach and have to use more physical effort pulling them than a hydraulic disc brake setup would require, for riders with smaller hands and those without as much hand strength, that could be a point of fatigue or difficulty, but at least they have motor inhibitors built in for safety and the rubber edges and an integrated bell on the left, I’m also told that they tend to be easier to adjust by hand by the owner vs. needing a shop
  • The display panel is not removable and could take some weather-wear or get scratched at bike racks… I do like that it has a USB type A port for charging your phone or other portable electronics on the go and that they’ve upped the output to 1 amp vs. 500 milliamps for faster fills on the go
  • I prefer little trigger shifters vs. the large SIS Index thumb shifters used here because they don’t take up as much space and are easier to reach when holding the grip… but an engineer from Rad Power Bikes told me that they chose these larger shifters to make room for the twist throttle and cutoff switch on the right side, also, the big shifters can be easier to use with gloves
  • Minor gripe here, the headlight is mounted to the suspension arch vs. the head tube or stem and that means it could bounce around on rough terrain vs. being suspended and smoother, if you get the optional front rack, it can be relocated to the bottom and then it becomes “sprung”
  • The battery position is good, but the top might get a little dirty or scratched if you’re not careful about how you step onto the bike, it’s right there in the main standing/pedaling area so a bit more exposed
  • The step-thru size felt a bit small to me, I’ve got a 30″ inseam and am 5’9″ tall and would probably opt for the larger high-step model to get full leg extension
  • There are some advantages to the new rear brake caliper position (wires aren’t in the path of the optional rear rack) but the way it’s tipped back, it seems like water and dust could collect on the wire and get pulled down into the cable housing over time, creating some friction and drag in the brake system and more work for your right hand pulling the rear brake lever, this would not be an issue if it used a hydraulic brake line vs. mechanical

Court, I can’t tell you how much I appreciate your detailed, comprehensive e-bike reviews. You have helped me so much. Not just with which bike might be best for me but understanding e-bikes in general. Thank you!

One thing I noticed while reading the RadCity step-thru review is you mention it has a Shimano Acera derailleur. According to the Rad website the 2019s have the Shimano Altus derailleur. Does this make much of a difference? One other question, does the rear brake light go on when you apply the brakes even if the lights are not on?

Again, thanks so much for all you do.

Hi Sandra! The bike I reviewed definitely had the Shimano Acera, you can see it in the second photograph, but it’s not a dealbreaker if they no longer include it or it was a mistake on the demo bike. It’s a step up from Altus, might be slightly lighter or more precise. I remember asking about this during the review, so I’m surprised that their website says something different. Dare I say, maybe THEY are wrong :D In any case, yes, I believe that the rear light does switch on even if the lights aren’t officially enabled. It’s a great safety feature. RAD did a wonderful job with the 2019 models, it’s a great lineup and I’m excited for them and you if you get one! So many awesome products to check out this year. Thanks for your comment, I’d love to hear back if you get one and care to share your experience riding :)
