Rad Power Bikes RadCity 5 Plus Step-Thru Review 2024
A reserved, reliable, and hard working commuter e-bike with a new hi-vis color!
At the heart of the RadCity 5+ ST (and all Rad bikes) is a dependable motor with relatively reserved power output. With 750 watts of nominal power, this bike isn’t lacking – but Rad’s dialed-in approach gives it a safe and steady feel that’s still fun to ride.
As you’d expect from a bike made to cover lots of time and distance on a daily basis, the RadCity 5+ ST is also remarkably comfortable. The custom saddle is ergonomically-shaped with just the right amount of squish, while the Dutch-style handlebars and ergonomic grips provide a similarly comfortable fit.
The special edition of the bike leans into its commuter side with straighter low-rise handlebars and a non-adjustable stem to offer more precise steering control and stability. Additionally, with a bright, contemporary Tiger Orange paint job, it’s impossible to miss out in the wild!
Dive into the full Rad Power Bikes RadCity 5+ ST review below to see the bike’s test results and more.
- Reliable and steady power from the 750W rear-hub motor. It’ll get you moving quickly, but not TOO fast.
- A comfortable ride for long commutes with a well-designed saddle, ergonomic grips, and a mostly-upright riding position.
- Pros of the Special Edition include a high-visibility Tiger Orange paint job, a stable standard stem, and low-rise 730mm ergonomic handlebars for excellent control and steering response.
- Easy to hop on/off with a step-thru frame that has a 16” standover height.
- A high-tech look and feel with Rad’s dual displays.
- More room than usual for cargo on the rear rack; instead of 55 lbs, it holds up to 59.5 lbs.
- We liked the comfort and modulation of the twist throttle.

Rad Power Bikes RadCity 5+ ST Review: Speed Test
Our Speed Test entailed riding the RadCity 5+ ST along a predetermined section of our local bike paths. While doing this, we recorded our maximum speeds without pedal assistance and in each of the bike’s 5 pedal assist system (PAS) settings.
When using no power from the motor, we applied a casual level of effort to observe the difference the PAS would make; our speed was 9.7 mph. In PAS 1, we felt a mild increase in speed up to 10.7 mph. PAS 2 brought a measured boost up to 14 mph, while we noticed a significant jump in power using PAS 3 that carried us to 18.8 mph. In PAS 4, the difference became more subtle, with a push up to 20.1 mph. Our measured speed actually decreased slightly in PAS 5; we reached a maximum of 19.7 mph.
This decrease was most likely due to variations in the path we were riding on, as the power level of the bike did not feel different between PAS 4 and PAS 5. Upon further testing, we observed that PAS 5 did have a noticeable difference in power output when traveling on an incline, but due to the RadCity 5+ ST’s 20 mph motor-assisted speed limit (as a Class 2 e-bike), the bike’s highest settings seemed identical in power on flat ground.
When considering the RadCity’s distribution of speed and power, as shown in the graphic above, the bike performed decently in this test. We typically prefer a more linear distribution with even, incremental increases in speed and power throughout – similar to what is shown between PAS 1 and PAS 3 – but we appreciate the flexibility provided by the current programming.
PAS 1 removed most of the RadCity 5+ ST’s weight, making it feel much like a non-electric bike for those who might seek a workout. PAS 2 provided a moderate level of power for casual rides , while PAS 3 felt more appropriate for faster travel. For those in a hurry, PAS 4 and 5 allowed for maximum speed, while offering flexibility for smoother or more difficult terrain, respectively.
During this test, we also evaluated the bike’s throttle, accessed with the half-twist grip on the right handlebar. This functioned effectively in carrying us up to 20 mph, with gradual, steady acceleration.
Overall, while we wouldn’t mind seeing more evenly-distributed levels of power and speed in each of the RadCity 5+ ST’s PAS settings, we generally liked its performance. It provided a functional range of assist settings for different types of riders and purposes, with a characteristic steadiness that was both confidence-inspiring and fun.
Rad Power Bikes RadCity 5+ ST Review: Range Test
Rad Power Bikes advertises a range of between 25 and 50 miles from the RadCity 5+ ST’s 672 watt-hour (Wh) battery. To evaluate this claim and measure the bike’s performance in real-world conditions, we pedaled it along our local bike paths in PAS 1 and PAS 5 until the battery was fully depleted.
We exceeded Rad’s advertised range in both tests, with results of 37.3 and 64.3 miles in the bike’s highest and lowest assist settings, respectively.
Compared to similar commuter-style e-bikes we have tested, the RadCity’s PAS 1 results were relatively average, but its PAS 5 results far exceeded those of other bikes with similar specs. Its 672 Wh battery is smaller than we typically prefer in relation to its motor (a 1:1 ratio of battery watt-hours to motor watts is a good starting point), but the RadCity 5+ ST performed as well as some other e-bikes with larger batteries.
You’ll notice that the RadCity went further than the Ride1Up 700 Series and the Aventon Level.2, and went less distance than the Velotric Discover 2.
This efficiency was apparent when comparing the bike’s test results to our estimates based on its specs. With a 750W motor and a 672 Wh battery, we anticipated that its PAS 5 test would last roughly 54 minutes and yield approximately 17 miles of range, but its real-world performance was significantly better. We measured 119% greater distance and 126% more time on the bike than expected.
This improved efficiency is likely due to the bike’s programming and motor limitations. Where most brands using 750W rear hub motors will spec components with a higher peak wattage, Rad Power Bikes does not allow their motors to peak above the nominal wattage. Additionally, their e-bikes’ nominal output is limited below the usual 750W to comply with CPSC guidelines.
As such, the RadCity 5+ ST uses less energy than many of its competitors, thereby extending its range. The roughly 37-64 miles of range we observed should give most commuters plenty of breathing room to soothe range anxiety; this bracket is likely to account for a single extreme commute or several shorter commutes across multiple days.
Rad Power Bikes RadCity 5+ ST Review: Hill Test
Using only the power of its motor, the bike carried our test rider Justin up the path in 1:54 with an average speed of 9.5 miles per hour. Its results improved with added human input in our PAS 5 test, where Justin made the climb in 1:30 at 12.1 mph.
On paper, the RadCity 5+ ST’s results were relatively slow in comparison to similar commuter bikes we’ve tested, though this was not unexpected. Rad Power’s e-bikes are typically slower in this test for the same reasons the RadCity performed well in our Range Test; with no higher peak wattage, the bike simply lacked the power needed to climb the hill quickly.
The 750W motor did not struggle or falter during our test, which indicates that it possesses the power needed to handle intimidating hills. As such, the RadCity 5+ ST can clearly assist its rider with steep inclines, but may take more time while traveling at a slower speed than some of its competitors. This lines up with our previous experiences with Rad Power’s e-bikes; they may not be the fastest, but they are reliable and effective.
Rad Power Bikes RadCity 5+ ST Review: Brake Test
We used the above process to evaluate the performance of the RadCity 5+ ST’s hydraulic brake system. Rad’s website does not specify any particular brand of brakes, but those on our test bike were made by NUTT (as we’ve seen on other Rad Power e-bikes we’ve tested) and use 180mm rotors.
After three tests, we calculated the RadCity’s average stopping distance to be 24’-5”. This is a relatively extended distance when compared to the results from similar e-bikes we tested previously, though it is still within our range of expected performance. The category average for all other commuter-style e-bikes using hydraulic disk brake systems is currently 21’-9”, placing the RadCity 5+ ST over 2.5 feet beyond the average.
Considering that previous Rad Power Bikes with the same brake system performed much better, this is likely a result of the bike’s tires; we noticed during braking that the wheels had a tendency to lock up and slide. This sometimes resulted in significant fishtailing, though in most cases the bike remained stable. With a relatively light tread pattern, the tires seemed to lack some grip, resulting in a “skating” effect that extended the bikes’ stopping distance.
While the RadCity 5+ ST’s brakes successfully stopped the bike safely and effectively in a reasonable distance, we recommend that Rad consider equipping the bike with tires with a greater coefficient of friction. We appreciate the custom tires’ low rolling resistance in increasing energy efficiency in other tests, but we think the bike’s braking performance has some room for improvement. “Stickier” tires would help it to stop faster and likely remain more stable while coming to a stop.
Rad Power Bikes RadCity 5+ ST Review: Ride Quality
With just a single frame size, the RadCity 5+ ST is designed to fit riders from 4’-8” to 6’-1”; taller riders will likely want to consider the standard high-step version of the bike which accommodates those up to 6’-5”. In our experience, the geometry worked better for those in the low and middle sections of the spectrum; with the seatpost fully extended, our testers around 6’ tall had less leg extension than expected.
The bike’s step-thru frame design makes mounting and dismounting a breeze; with a standover height of 16”, riders need only to lift a leg and pass it over the bottom bracket. Speaking of the frame, however, we absolutely adore the special edition’s Tiger Orange color! The most recent generation of the RadCity (and many of Rad’s e-bikes) has a unique, contemporary design with an industrial feel, but the new high-visibility paint job elevates and completes the design while making the bike stand out on the road.
We experienced a mostly-upright riding position (a slight forward lean) with the special edition’s fixed handlebar height and standard-style stem. The standard version offers greater customization in rider positioning with an adjustable stem that allows for changes to the handlebar height, reach, and overall verticality.
We liked the bike’s custom saddle and ergonomic grips, though operation of the bike took some getting used to. It is common for e-bikes to have their throttle on the left handlebar, but the limited edition of the RadCity places its over-the-bar Shimano Altus thumb shifter and half-twist throttle both on the right handlebar. These did not interfere with each other, though we did exercise a bit more care to avoid accidentally engaging the throttle. The standard version’s below-the-bar shifter felt a bit more natural.
On the special edition, the combination of 27.5”x2” tires and 730mm handlebars resulted in predictable and relatively precise handling, while the standard version’s Dutch-style handlebars felt more relaxed. For a commuter, we preferred the comfort and control of the wider, flatter handlebars in general, though both setups were fine – just different!
The bike’s ride was made relatively smooth due to the larger tires and suspension fork with 50mm of travel. We wouldn’t mind seeing a fork with greater travel, as the included fork bottomed out on a few occasions even with its preload set high.
We found the bike’s interface to be both cool and unique overall; with dual displays, the RadCity has a high-tech feel (although we’d prefer a percentage-based battery readout over the bar system). When we originally reviewed the bike in early 2022, we pointed out that its cable management (a series of zip ties) could use some improvement and this critique still stands. Especially on a limited-edition version of the bike, we would prefer a neoprene sleeve, a coil wrap, or some other method of taming the myriad of cables.
One area that Rad excels in is accessories. The RadCity 5+ ST includes full-coverage fenders with mud flaps, a high-capacity cargo rack (up to 59.5 lbs), an integrated tail light / brake light and headlight; in short, all the commuter essentials. The brand offers a host of optional extras, however, including child seats, cargo baskets and bags, ride quality improvements, and more.
To summarize, we found the overall ride quality of the RadCity 5+ ST to be great – and with a couple of minor improvements, it would be even better!
Rad Power Bikes RadCity 5+ ST Review: Summary / Where to Buy
The standard version of the bike is tried and true, while the limited edition version of the bike includes some appreciated design changes; we hope Rad continues to offer the bright and eye-catching Tiger Orange paint job! Additionally, while we liked the casual feel of the original/standard version of the bike, the limited edition seems to take itself a bit more seriously as a commuter with its wide, low-rise handlebars.
When it comes to performance, there were some artifacts of Rad’s standard approach that, at face value, may initially seem to be a downside. But we’ve come to appreciate the brand’s thoughtful, thorough approach and the RadCity’s tuned-down feel. The bike proved to have impressive range, a decent balance of speed and power, and slower – but quite steady – climbing ability.
We’d (still) like to see improved cable management, and we think the bike’s braking ability would benefit from different tires, but overall, we’re very pleased with the feel and function of the RadCity 5+ ST.
If safety, reliability, and performance are at the top of your list when considering a commuter-style e-bike, we highly recommend this (or really any) bike from Rad Power!

I just replaced my RadCity with the RadCity 5 Plus Step-Thru. I unboxed it and took it for a spin yesterday. At my age I really appreciate the added safety that the step-tru provides me. In my opinion, the improvements noted in the article are well worth the cost increase. My wife has the earlier version of the step-thu and both of us really like the extra space available with the new battery placement on the 5 plus. Sadly, my suspension fork needs warranty work. Even with max pre-load, my 190 pound weight made the fork bottom out when going over any surmountable curbs. With no forks in stock at RadPower I estimate that I will be riding with the suspension locked for 3 to 6 months before I can get a new fork.
John Snyder says
I purchased a Rad City S/T in 2019. It is a great bike, but does lack enough torque to do any serious hills. The specs for torque on my bike is 40NM. What is torque rating on City 5? Thanks
Griffin Hales says
58Nm on this one.
Jack says
My wife and I both have RadCity5+ bikes.
Both required replacement controllers almost immediately. Mine is currently out of commission with undiagnosable electrical problems. Please beware purchasing RadPower. They don’t provide any warranty service either, though they will send warranty parts.
I will say when they work they’re a ton of fun. And price is great… with the caveat that you get what you pay for. The front cargo rack and a big basket on the back made these bikes our grocery haulers, work commuters, and weekend go anywhere bikes.
The Step through version is not big enough for me and I’m only 5’10” with 32″ inseam… So take their fit suggestions with a grain of salt. My wife’s is Step Through, mine is Step Over. I’d say 5’2″-5’8″ for Step Through, 5’9″-6’2″ for Step Over unless you want to start swapping seat posts and stems.
