https://electricbikereview.com/rad-power-bikes/2015-radrover/ The Rad Rover by Rad Power Bikes is an Indiegogo funded electric fatbike with a powerful 500 watt motor, ample 48 volt battery and seven speed drivetrain. Comfortable saddle, ergonomic grips and suspension fork with lockout, two color choices but only one frame size 19″. Integrated headlight, sturdy mechanical disc brakes, quality Kenda fat tires and two drive modes (throttle and pedal assist). No quick release on the wheels, battery has to be powered on independently from the display, no bottle cage or rack bosses but there are optional fenders available and you get a solid one year warranty (unique for a crowd funded e-bike). RadRover is currently for sale direct.
