Price: $1499.00 | Model Year: 2020 | The high-step version of Rad's folding, fat tire, off-road capable, compact electric bike. Custom 3.3
The high-step version of Rad's folding, fat tire, off-road capable, compact electric bike. Custom 3.3" wide tires have reflective sidewalls, puncture resistant lining, and all-terrain checkerboard tread. This is the fourth generation RadMini, and it comes standard with wide plastic fenders, integrated lights, and a spring suspension fork with preload adjust and lockout
Only available in one frame size and one color, but the handlebar and seat height are adjustable so it can accommodate a wide range of body types. The folding joint is fairly narrow, so you won't bump your knee, but there are no bottle cage bosses. The frame feels very solid and doesn't suffer from frame flex, it's lighter than the RadMini Step-Thru at 68lbs vs. 69lbs
Large 180mm disc brake rotors provide excellent stopping power and control, both brake levers activate the rear light for safety and cut power to the motor. RAD optimized 750 watt Bafang planetary geared hub motor feels powerful but smooth, you can adjust the top speed down from 20mph in the settings menu. Large aluminum alloy folding pedals feel solid, alloy chainring guide keep your pants clean while reducing chain drops
Wide 11 to 34 tooth gearing makes it easy to pedal up steep hills and comfortable to maintain ~20mph top assisted speeds without feeling outpaced, large thumb shifter is intuitive but a little difficult to reach compared to triggers. The new twist throttle design feels good and overrides pedal assist at all levels for easy starts and extra power when needed. Full sized 1 amp USB charging port below display, excellent kickstand placement, large selection of racks and accessories that are cross-compatible with other RPB models
