I think I’m about to buy a Velotric T1 ST Plus which would be my first ebike.

The manual says to store it indoors at a temperature of 50°F to 77°F (10°C to 25°C). However the location I actually have to store it in is in an uninsulated shed that will probably reach 120ºF (50ºC) in the summer in baking sun, and below freezing in the winter.

Is this going to kill the bike or its battery?
