Rad Power RadCity 5 Plus Review

Rad Power Bikes has been the default answer to "which electric bike should I get" in the United States for the better part of a decade. The company has been building since 2007, has sold in the hundreds of thousands, and for a long stretch was the only ebike brand a non-cyclist could name. The RadCity is its city bike: upright, 27.5 inch wheels, a rack, fenders, lights, and a throttle.

Read the specification next to a Velowave or a Heybike at the same price and the RadCity looks distinctly ordinary. Similar money buys more amp hours, a bigger nominal motor rating, sometimes a torque sensor. If you rank bikes by spreadsheet, the RadCity loses.

That comparison misses what people are actually buying. An ebike is not a one-off purchase like a blender, it is a vehicle with consumable parts, a battery with a finite life and a proprietary controller. What matters at year four is whether anyone will sell you the part and whether anyone will fit it. That is the axis Rad competes on, and it is worth being clear-eyed about how much it is worth to you.

Verdict

Build and support carries this score. Rad sells spare parts for its own bikes directly, publishes service documentation, and has a track record long enough that a five-year-old RadCity is still a supportable machine. Ride quality is held back by cadence sensing, which makes power delivery feel switched rather than proportional, and by a weight in the mid-60s. Range is solid rather than special: a roughly 670 Wh pack is competitive but not class-leading. Value scores lowest of the four because the sticker price sits above bikes with better paper specifications, and that gap is the price of everything else on this list.

What buying from the biggest brand actually buys you

Three concrete things, none of which appear on a spec sheet.

A parts supply chain. The failure mode that ends most cheap ebikes is not a crash, it is a dead controller, a cracked display or a battery that has lost half its capacity, on a bike whose importer has moved on to a new model with different parts. Rad sells its own spares directly and has done for years. That is the difference between a repair and a skip. It also means an independent shop can order the part rather than telling you they cannot help.

A service route. Rad has run mobile mechanics, company stores and partner shops at different points, and that footprint has been reorganised more than once, so verify what exists at your postcode rather than assuming national coverage. Where it exists, the value is that somebody else diagnoses the electrical fault. Diagnosing an intermittent cutout through a support chat window, with your bike in your garage, is genuinely miserable.

Documented failure modes. A bike sold in very large numbers over many years accumulates a public record. Forums know which connector corrodes, which bearing goes, which firmware version misbehaves. On a bike that has sold two thousand units, you are the test programme.

Weigh this honestly rather than romantically. If you plan to ride two miles a day for two years and then move on, none of it is worth paying for and you should read best electric bikes under $1,000 instead. If this bike is replacing car trips and you expect to keep it until the battery is done, supportability is worth several hundred dollars. Our ebike maintenance and repair guide puts numbers on what that ownership actually costs.

How it rides, cadence sensing included

The RadCity is a classic upright city bike. Swept bars, a tall head tube, a saddle you sit on rather than perch on, and 27.5 inch wheels with a commuter tyre in the region of 2 inches wide. That geometry does two useful things: it puts your head up where drivers can see your face, and it makes low-speed manoeuvring easy, which matters on a bike this heavy.

The 27.5 inch wheel is an underrated choice in a market that has drifted towards 20 by 4 inch fat tyres. A larger diameter wheel rolls over a pothole edge at a shallower angle and loses less speed doing it, and a narrower commuter tyre at proper pressure has far less rolling resistance than a balloon tyre at 15 psi. On pavement, this is the faster and more efficient setup, and it is one of the quiet reasons the RadCity feels better than its motor rating suggests. There is more on this in ebike tyres and wheels explained.

Now the honest part. Rad has traditionally used cadence sensing on the RadCity, and cadence sensing has a characteristic feel that some riders never stop noticing. A ring of magnets on the crank tells the controller only whether the pedals are moving. Turn them and you get whatever power the assist level dictates, after a short delay. Stop and the power runs on for a beat. The bike does not care how hard you are pushing, so your gears become close to decorative and the assist buttons become the throttle.

Two things soften this. The RadCity has an actual throttle, so when you want fine control you use your thumb rather than fighting the sensor. And Rad tunes its assist levels conservatively, so the arrival of power is less startling than on some budget bikes. It is still a step behind the proportional feel of a torque sensor, which is the single clearest ride advantage a bike like the Aventon Level holds over it. Check the current specification, since Rad has been introducing torque sensing across parts of the range.

Braking on a bike in the mid-60s carrying a rider and a load is not a place to economise. Hydraulic discs with rotors of 180mm or larger are the appropriate specification for this weight class, and they are the component you should verify before ordering rather than assume. The reasoning is laid out in our guide to ebike brakes.

Motor, battery and what range to actually expect

The RadCity runs a geared rear hub motor in the 750W class, which is the legal ceiling for a compliant ebike in the United States. Geared hubs are the right choice here: the internal reduction lets a small motor produce useful torque at low wheel speeds, which is what you want pulling away from a light with groceries on the rack. What they cannot do is use your gears. A hub motor's speed is locked to the wheel, so on a long steep climb it falls out of its efficient range and starts making heat instead of progress. That limitation applies to almost every bike in this category and is explained properly in mid-drive versus hub motor.

The battery is the number that predicts range, and the number to use is watt hours, not amp hours. A 48V 14Ah pack is 48 times 14, or roughly 670 Wh. Compare that figure across bikes and you are comparing like with like; compare amp hours across different voltages and you are comparing nothing. That distinction is worth ten minutes of your time in 36V vs 48V vs 52V ebike batteries.

These are estimates derived from pack size and the power a heavy upright bike needs at city speeds, not measured results. A 220 lb rider, a headwind, cold weather or a hilly route will move every row down, sometimes by a third. The useful takeaway is the shape: the difference between the top and bottom rows is a factor of two and a half, and it is entirely under your right thumb. Anyone shopping primarily on distance should read longest range electric bikes before choosing on a headline number.

Payload, frames and the kit that comes fitted

Rad quotes a total payload for the RadCity in the region of 275 lb, covering rider, cargo and anything on the rack together. That is a system limit set by the frame, wheels and brakes, not a marketing number, and it is one of the few specifications worth treating as a hard boundary. A 210 lb rider with a 25 lb load and a laptop is already close to it. Riders near or above that figure should look at the purpose-built options in best electric bikes for heavy riders, where frames and wheel builds are rated higher.

The rear rack is rated separately, typically in the 50 to 55 lb range, which is enough for two loaded panniers and a week of shopping. Rad also sells an unusually complete accessory catalogue for its own platform: baskets, passenger kits, bags and mirrors designed to bolt to the mounts the bike already has. That sounds trivial until you have spent an evening trying to make a generic rack fit a frame that was not designed for one. The upgrades that are actually worth money are covered in ebike parts and accessories.

The step-through frame deserves more respect than it usually gets. On a 65 lb bike with a loaded rack, swinging a leg over the saddle is the least stable moment of the whole ride, and it is where a lot of low-speed falls happen. A low standover removes that moment entirely. It is not a womens frame or a compromise for shorter riders, it is the better ergonomic choice for most people carrying anything. Both electric bikes for seniors and electric bikes for women go through the fit implications.

Lights are wired into the main battery, and a brake light in the rear unit is a genuinely useful safety feature on a bike that decelerates hard from 20 mph. Fenders are fitted rather than optional, which matters if you intend to ride in the wet. See riding an ebike in the rain for what the rest of the bike needs in that weather.

Specifications at a glance

Rad revises the RadCity between generations and the plus designation has covered more than one configuration, so confirm the motor, sensor type, brake type and battery size for the exact model in front of you rather than relying on any of these bands.

Who should buy it

Buy it if this bike is going to be transport. If it replaces car trips, carries shopping, gets ridden in weather and needs to still work in year five, the supportability argument is real money rather than sentiment. Buy it if you want a throttle, which the RadCity has and a great many bike-shop brands do not. Buy it if you want a step-through commuter that was designed as one rather than converted into one.

Buy something else if your priority is the specification per dollar. There is no version of this comparison where the RadCity wins on paper, and pretending otherwise would be dishonest. Direct-to-consumer brands will sell you more capacity and more power for less, with the trade-offs set out in our Lectric brand guide and the Lectric XP 3.0 review.

Buy something else if you need to keep pace with 35 mph traffic. The RadCity is Class 2, which means the motor stops helping at 20 mph, and no amount of pedalling makes a 65 lb upright bike comfortable above that. If your commute is arterial roads rather than bike lanes, you want a Class 3 bike instead. Read ebike classes explained and then the Class 3 explainer to see what changes, then compare against the bikes in best electric bikes under $2,000.

Buy something lighter if the bike lives up a flight of stairs or goes on a trunk rack. Sixty-five pounds is a two-person lift in practice, and no amount of good engineering elsewhere makes up for it. The lightest electric bikes covers what is available when weight is the constraint.

Where to buy

Rad sells direct and through partner shops depending on the market. Before you order, do one piece of homework: search for what service coverage exists at your address. The entire argument for this bike over a cheaper rival rests on that answer, and it varies enormously between a dense metro area and a small town.

If the answer is nothing within an hour, the support premium mostly evaporates and you should be shopping on specification like everyone else. If there is a partner shop nearby, ask whether they will assemble and safety check a direct order, and what they charge. That combination, a mainstream brand bought direct and set up by a mechanic, is quietly the best version of this purchase. From there, compare against the rest of the Class 2 field and read buying a used electric bike if you would rather let someone else take the depreciation.
