Another downside and word of caution: I left my $1200 Rad City bike in the garage over the winter and it got unplugged somehow. By spring it was no longer able to charge, and replacing just the battery cost another $600.
- jacquesm 5y agoIt should have kept charge easily if it was full when the winter started. I've two 36 V nominal packs here lying around in case the other one dies (but it never does) and they've dropped 0.5V from 39 or so over the winter. Quite probably there was something wrong with that previous pack already that caused a self discharge rate so high that the pack had gone completely empty. The best way to store them for long term is to charge to either 3.7 or 3.9 V / cell (depending on whether you want to check them in 3 or in 5 months).
- jdboyd 5y agoI hope that your bike failed like that was a fluke. I didn't recharge my $1100 Ancheer all winter and it was fine when I started using it again 2 weeks ago. I didn't even think it might be a problem to worry about. I'll have to be more careful next winter. FWIW, I would encourage anyone who isn't certain enough about it to buy a $3,000 bike to start with a cheaper Chinese model to decide if it is for them. There are things I don't love about this bike, but it definitely has me sold on electric assist bikes given the hills I have around me and my knees, and when it comes time to replace it, I expect I will get a nicer model.
