https://electricbikereview.com/rad-power-bikes/radrover/ The 2016/2017 RadRover from Rad Power Bikes strikes an excellent balance delivering high power with mid-level components for a reasonable price, you get throttle and pedal assist with an on/off on the throttle! solid one year warranty for the original owner, flat rate $175 shipping in the US. Even though the battery and controller box are bolted on vs. integrated into the frame, they use extra bolts for strength and kept them mostly out of the way, both are mounted low for improved stability. Nice extras including an integrated LED headlight, stand alone rear light, USB charging outlet on the battery, handle at the back of the seat, quick release front wheel, bash guard on the chainring and derailleur… optional fenders and rack. Only available in one frame size but comes in black or white color choices, the 180 mm disc brakes work well enough but hydraulic would be nice, the grips spin a bit if you squeeze hard, excellent kickstand placement, clean wire integration.
