Battery Sport Drive 504 Wh (14 Ah)
Fully integrated battery with the 4th generation Sport Drive system. The battery has a capacity of 504 Wh. At the same time, it's still easily removable so you can charge it separately if needed.

The battery can be charged directly in the frame of the e-bike, or it can be removed for charging. You can travel up to 100 km on a single charge (depending, of course, on the profile of the track and how the assistance is used).
