I live in the Memphis area and the temperatures get down to below zero for weeks at a time. What happens to an ebike battery in below freezing temperatures? Does the battery life go down? Is there any speed or performance degradation?
Ebikes work fine in winter. In my experience with cold weather riding there is no noticeable different in the speed, power or range of my ebike.
Just make sure you have studded tyres if you are riding in icy conditions. One benefit with an ebike is that you don't notice a difference in speed with studs on the tyres. Without an ebike studs make it much harder to pedal.
