Rad Power Bikes RadCity Overview

Rad Power Bikes RadCity

The RadCity is great for the neighborhood and urban commuting. Rad Power Bikes designed this bike to be a comfortable cruiser, thanks to the low-profile design and the upright frame.

The combination of its 1 x 7-speed drivetrain, half-twist throttle, and puncture-resistant tires provides an excellent riding experience, even when climbing foothills.

Of course, the RadCity 4 top speed of 20 mph does not exactly classify it as the fastest electric bike, but that’s more than enough speed for your everyday commute in the city.

Let’s begin the Rad Power Bikes RadCity 4 Review with a few of the good stuff and some areas that need improvement.


  • Hard-to-beat price for a Class 2 (Throttle on demand) e-bike.
  • Rear rack can support up to 60 lbs load.
  • Durable motor with quiet operation.
  • Puncture protection and reflective stripes on tires.
  • Comes complete with fenders, rack, and integrated light.


  • Available in only one size and color.
  • The location of the water bottle cage below the downtube is not very convenient to reach on the go.
  • The bike is heavy at 64 lbs.
  • Not as efficient at climbing steep hills compared to other mid-drive electric bikes.
  • Assembly can take up to an hour, which is a longer time than some other e-bikes.

Things to Consider Before Buying an E-bike

Buying an e-bike is usually an investment because even the most affordable models can cost up to a thousand dollars or more. For this reason, I strongly advise that you take a few moments to ponder the following suggestions before making any financial commitment.

  1. Purpose and Terrain:Consider what you want to use the e-bike for and where you will mostly use it before opting for a model. A commuter bike would be your best bet if you want something to cruise around town.

A cargo model works best if you want to carry plenty of stuff or an additional passenger during rides. Consider an electric fat bike for tackling challenging terrains.

  1. Batteries: Lithium-ion batteries are widespread, but choose one from a reputable brand, such as Sony, Samsung, and Panasonic. Consider a battery with not less than 800 charge cycles if you want one that will last for a long time.
  2. Range: The range refers to the total distance the bike can go on a full charge. An e-bike that can travel more than 25 miles is a great choice if you plan to use it for your daily commute.
  3. Motors: Geared hub motors with 500-watts or higher are an excellent choice. Entry-level and mid-entry bikes typically have their motors on the wheel. It will cost you more if you prefer one with the motor inside the frame. In either case, motor performance is far more important than its location.
  4. Assist Level: Consider an electric bike that offers up to three or four motor-assist levels. A walk-mode is a big plus if you prefer more sophistication.

Features and Benefits

Now, let’s take a closer look at the RadCity 4 specs and see why it ranks as the best commuting electric bike of 2021.



Rad Power Bikes built this bike with a 6061 aluminum alloy – a durable construction material. The bike is only available in one color and one frame size of 18.5 inches.

Short riders who prefer high-step frame style bikes and very tall riders who prefer more than average leg clearance may find the one-size frame limiting. Thankfully, the bike’s stem is adjustable.

The aluminum material adds to the bike’s weight. At 64 pounds, the RadCity is on the heavy side. You may find it difficult to carry the bike upstairs if you live in an apartment.



The bike is engineered with a 750 watts direct drive hub motor with 40 Nm of torque. This motor won’t power through steep hills and is definitely not a great choice for long-distance rides. But it is more than enough to zip through city traffic.

RadCity 4 top speed of 20 miles per hour is a direct function of the motor assist system. While engaging the motor usually drains battery power, the RadCity 4 specs feature a motor with a regenerative braking system.

What this means as you pedal around town and apply the brakes, some pedaling power goes back into the motor. This can increase brake life and extends the battery range.



The RadCity is built for urban cycling. This explains its rather basic spring fork. But with 100 mm travel, lockout, and preload adjustment, it is adequate for the everyday city rider.

The spring fork adds to the bike’s weight, but the low profile and the wheel size combine to provide smoother rides, even on rough city roads.

Wheel & Tires

Wheel & Tires

Fitted with 26” Weinmann Goliath, double-wall alloy wheels, and 2.3” puncture-resistant tires, there is little chance of experiencing flats with the RadCity, even when you ride on bad city roads.

The tires are grippy than others on many commuter e-bikes, thanks to the treads, which are more prominent.



The drivetrain on this bike comprises a Shimano SL-TX50-7R thumb shifter and a 7-speed Shimano Altus derailleur. This combination makes shifting very smooth and consistent with the pedal-assist system.

Plastic fenders provide full coverage for the drivetrain, protecting it from dust, sand, and debris. Chain drops are rare with this level of protection.




RadCity features mechanical disc brakes 180 mm front and rear rotors. This braking system is highly responsive and can bring the bike to a quick stop. Fortunately, more tire treads on the tires mean you are less likely to experience skidding.

Also, the brake pads last longer than those on similar bikes because of the regenerative braking system of the bike.



One impressive RadCity 4 specs are the removable 672 Wh Samsung lithium battery pack. I like that I don’t have to bring the entire bike indoors during charging. I can simply detach the battery and charge it inside.

A removable battery also means you can easily detach it during cleaning and reinstall it afterward.

In terms of performance, the battery can last for a long time and can supply power for a decent range.

The 2 amps charger is pretty basic, though. Consider upgrading to a 3 or 4-amp charger for faster charging.

Display/Assist Modes

Display/Assist Modes

Sitting squarely in the center of the handlebars is a 2.75” backlit LCD with bold readouts. You don’t have to look sideways or take your eyes off the road to steal a glance at the display, thanks to the center positioning.

The display is fixed, so you can’t take it off during cleaning, but you can easily adjust the angle. This is a useful feature because it helps you avoid flare, especially when riding in bright light conditions.

Thankfully, you can easily see the readouts even in low-light conditions since it is a backlit display.

The display comes equipped with a USB port at the bottom, allowing you to charge your phone and other portable devices on the go.

The LCD shows the following metrics:

  • Battery level indicator
  • Speedometer (current speed, average speed, max speed)
  • Pedal-assist level
  • USB charging
  • Odometer
  • Light indicator
  • Wattmeter

The twist throttle and pedal-assist system are noteworthy RadCity 4 specs. The half-twist throttle features a 12-magnet cadence sensor that offers five pedal-assist levels.

In a nutshell, twisting the throttle minimizes pedaling and provides supplemental speed up to 20 mph, which is the RadCity 4 top speed.
