Which battery should I take? The standard 7Ah/252Wh or the extra power 10Ah/360Wh?

For our BZEN Bikes you have the choice between our standard battery with 7Ah/252Wh and the extra power with 10Ah/360Wh. Depending on the terrain and assist mode used, the 252Wh battery offers assistance for 35-75 km and is perfect for your city rides. The 360Wh battery has 50% more power and can provide assistance for 50 up to 90 km. It is therefore useful when you regularly want to cover longer distances. 
The 10Ah/360Wh adds 600 grammes to the bike versus the 7Ah/252Wh battery.
