Out for a leisure ride yesterday with +April Armstrong
. That's a 48V 1000W 9Continents hub motor with a 20Ah LiFePO4 battery.
I used to scoff at electric bikes until a knee injury had me just looking at my bikes, instead of riding them. The motor has allowed me to return to bike commuting (15 miles each way), thereby getting my knee and supporting muscles into fighting shape. I don't have to worry about my knee getting angry while not yet halfway to work. The motor also gives the tandem serious hauling capacity. I have been able to pick up the weeks' groceries while hauling my monstrous work laptop, tools, packages, and my busted knee.
Plus, it's a lot of fun.
