What happens when the battery is low during my ride?
- Below 10% Charge: The bike enters "Conserve Mode," limiting power assistance to help you pedal more efficiently.

Yes. Removing the battery (and the Top Frame) can help reduce the overall weight of the
TM-B when transporting the bike in a vehicle or carrying it upstairs.
