Can I put a rear rack on it?
Some racks fit, but the wide rear tires require you to choose carefully when picking out a rear rack. Racks that connect directly to the seat post are the easiest to install, but do not have the payload of some full featured rear racks.
How Steep of a hill can the bike go up?
Hill performance depends on the weight of rider and gear and the steepness of the hill as well as some other factors. The 48 volt 15 amp continuous motor controller surprises everyone we have had test ride the RadRover, the hill climbing power is what distinguishes our bikes from competitors with lower voltage battery packs, lower current controllers, and higher speed motor windings.
