I'm looking for an electric mountain bike that I could use for commuting, touring, and some not-too-technical trail riding. Until now - I've only ridden road bikes. I'm leaning toward a 2018 PF5. I'm thinking the E-bikes designed for commuting might not do as well as PF5 off-road. For commuting, I'd like to get a rear rack, lights and perhaps fenders. Has anyone outfitted a PF5 or 7 this way? Would a rack rattle around too much off-road? How much of a pain would it be to take rack & fenders on/off? Any lighting option that would tap into the main battery?
