I've given up on e-bike conversions for now. It looks like at least $400 to get a decent kit and a Li-Ion battery, and to do it right at least $100 in bike shop labor. And that's not including the bike itself. You can get a 250V entry-level bike for $700-900 and it has a warranty. However, some of the reviews on those bikes sound like one or more have the old friction twist-shifters on the bikes, and I really don't want those. Are there any cheaper e-bikes out there that are aluminum and have real Shimano trigger shifters, with at least a 21-speed freewheel? Only that pedal drivetrain level or above would be worth buying, I'm not going to spend $700+ on a friction twist-shifter bike. Thanks for your input.
