Why Choose the Rad Power RadRunner 2?
Powerful motor, throttle, and battery
Like all Rad Power e-Bikes, the RadRunner 2 is powered by a rear hub motor. It’s rated 750W for extra oomph on steep gradients or under heavier loads, with pedal-assist or throttle mode up to 20 mph. This Class 2 e-Bike lets you choose between pedal assistance or pedal-free cruising while using the throttle.
Important: If you’re considering a used Rad Power RadRunner 2, double-check that its battery is not model RP-1304 or HL-RP-S1304. The CPSC recently issued a safety alert regarding these batteries, which have been linked to fire hazards across several Rad Power Bikes models, including the RadRunner 2.
Compact cargo design
The RadRunner 2 is what’s known as a utility electric bike, which can also be described as a compact cargo bike. It has a shorter wheelbase than long-tail cargo bikes or front-loading cargo models, which preserves more nimble handling closer to that of standard bikes. But there’s still plenty of room for cargo or space to transport kids at the back of the bike, thanks to the integrated rear rack. Rad Power offers tons of cargo accessories to fully customize your ride according to your needs— child seats, seat pads, baskets, panniers, handrails, footboards, and more.
Simple and reliable components
The RadRunner 2 is an approachable entry-level e-Bike with a comfortable setup and easy-to-use components. The single-speed gearing, externally mounted battery, and upright riding position let you simply focus on the ride ahead, especially for beginner e-Bikers. The wide tires help cushion the ride, and the step-thru frame makes mounting and dismounting a breeze. However, this older version of the RadRunner uses mechanical disc brakes instead of more powerful hydraulic brakes.
