Looking to start taking your e-assist bike on longer journeys? An extra battery might bring you peace of mind!

The Bosch Performance Line 500 Wh battery is available in 4 different configurations depending on what is compatible with your bike: the Power Packs, rack- or frame-mounted, and the Power Tubes, with a horizontal or a vertical orientation. When using the Bosch Standard Charger (not included), this lithium-ion battery requires about two hours to charge to 50% and approximately 4.5 hours to charge fully. These batteries have no “memory effect”: interruptions of the charging process do not harm the battery, thus a complete discharge is not required before plugging it back in.

Please note: no shipping is available for batteries at this time.

Compatibility:

Please check your bike for its battery compatibility. All batteries are final sale.
