RadCity 4 – Electric Commuter Bike Review

The RadCity 4 is a powerful city commuter with a comfortable upright seating position, thick puncture-resistant tires, front and rear lights, and a luggage rack on the back. It’s the perfect bike to hop on and get going straight out the box.

The 750W pedal-assist motor will push you along at a decent 20mph (20km/h), helping you to get around town without breaking a sweat. The long-lasting battery will take you up to 45 miles on one charge and can be conveniently removed to charge indoors overnight.

1.1 Tech Specs of RadCity

The RadCity 4 runs a 750W Shengyi Direct Drive Hub Motor which provides up to 40 Nm of torque and features regenerative braking. The pedal-assist motor offers 5 varying degrees of assistance controlled by a convenient Twist Grip throttle on the handlebar. To save battery, you can lower the assistance level and push harder on the pedals.

The integrated rear rack is welded from strong 16mm tubing and can hold up to 60lbs (27kg) of luggage. It fits all commonly available clip-on pannier bags and fits several other RadPower accessories.

Complete 45 miles or more of effortless cycling every day with a single charge of the battery which also powers a handlebar-mounted, backlit LCD display. Pop it out and charge it overnight with a supplied 2A smart charger that runs off standard 100-240V AC power outlets.

For instant stopping power, you get Tektro mechanical disc brakes with 180mm rotors, providing more than enough grip to stop you in any weather conditions.

With a tough aluminum frame capable of carrying a payload capacity of 275lbs (125kg), you should easily be able to carry yourself and as much luggage as you can handle.

1.2 Electronics

The rear hub motor is powered by a 672 Wh Samsung Lithium NMC Battery that can be removed and taken indoors to charge overnight. While attached to the bike it is secured by a keylock so that it cannot be stolen while parked.

The battery should last most cyclists an entire day of riding around town, typically covering up to 45 miles or more from a single charge. The battery also powers the front and rear lights plus the LCD Display which shows your speedometer, odometer, trip, watts, and pedal-assist level.

The RadCity 4 uses a Half Twist Throttle on the right handlebar grip to change between pedal-assist levels. This allows you to easily increase the power without taking your hands off the handlebars if you’re getting tired or need to go uphill.

Front and rear LED lights are included for night riding, with a lever-activated brake light on the rear for extra safety. All wiring and connectors are water-resistant and you even get a useful 5V USB port on the display.

1.3 Frame and Geometry

Unlike the previous RadCity that had both 16″ and 19″ versions, the new 4th-generation RadCity only comes in one size – 18.5“. However, it is very versatile with highly adjustable handlebars and a telescoping seat post, fitting riders between 5’11” and 6’5″.

The standover height on the standard version is 31″ with a seat height of 28″ – 37″. This means anyone with a leg length of about 2’3″ should be able to reach the ground while seated. There is also a step-through version for shorter riders.

The full length of the bike is 70″ across with a 43″ wheelbase and 14.5″ handlebar reach. The handlebars can be slightly adjusted for either a more upright or aerodynamic posture.

The frame is built from strong 6061 aluminum and features a front suspension with 100mm of travel, perfect for hopping curbs and bouncing over debris. You also get a heavy-duty kickstand, plastic fenders, and a 7-speed Shimano Altus drivetrain for gearing adjustments.

All this means the bike weighs a relatively heavy 64lbs (30kg) so it’s lucky it has such a strong motor to help you along.

1.4 Wheels and Braking

RadPower Bikes use 26″ x 2.3″ K-Rad tires supplied by Kenda, featuring the K-Shield puncture-resistant lining. The wide, soft tires help to reduce vibration while rolling easily over most obstacles and debris in the road.

They feature a medium-thick tread perfect for wet pavement or mild off-road riding through parks or along dirt tracks. The tires are fitted to 36H Weinmann Goliath alloy rims using strong 12-gauge stainless steel spokes.

Powerful braking is supplied on both front and rear wheels by Tektro mechanical disc brakes, using Tektro Aries levers and 180mm rotors. These provide excellent stopping power in all weather conditions and include a motor cutoff switch for extra safety.
