November 22, 20205 yr Hi Thought I would have a go at converting my old Specialized Hardrock just as a project and fact finding mission. I bought the cheapest kit available 1kw rear hub and a 52V 17.5 Ah Battery. A bit of overkill I know! Not a straight task as many have you believe. Various mods required but not a real problem. Flipped the switch on completion and off like a banshee. With it being a cheep kit there wasn't a PAS level assist setting or screen with it so it was either ON or OFF. No fun when you are on a ride out with a buddy on an organic bike. Caught me out a couple of times, head butting a tree on one occasion. Thankfully had a helmet on. Connecting the speed restriction wires for road use (250 Watts) meant the battery lasted for 40 ish miles on a good flat ride day. Bike now Sold and moved onto my second project.
