The Rad Rover is an affordable, powerful, electric fat bike with responsive 12-magnet pedal assist and twist-throttle on demand that has lots of accessory options including fenders and racks. The Rover has only one frame size but the top tube is sloped and the shorter stem pairs nicely with the mid-rise handlebar for upright or forward body position and taller or shorter riders, and also comes equipped with sturdy, oversized pedals.
