Bosch Smart System (BES3)Does the Bosch PowerTube 800 (smart system) fit a Bosch Smart System (BES3) bike?
Whether the Bosch PowerTube 800 (smart system) fits a Bosch Smart System (BES3) e-bike, and what to confirm on your own frame first.
Yes, with the right mount. The Bosch PowerTube 800 (smart system) is the native pack for a Bosch Smart System (BES3) bike (800 Wh, 36 V), charged through the Bosch smart-system round charge port.
| Battery | Bosch PowerTube 800 (smart system) (800 Wh, 36 V) |
|---|---|
| Native drive system | Bosch Smart System (BES3) |
| Verdict | fits (native pack) |
| Charge port | Bosch smart-system round charge port |
| Will not fit | a different drive system, or a different Bosch/Shimano generation even if the shape matches |
The Bosch PowerTube 800 (smart system) is proprietary to the Bosch Smart System (BES3) drive, so it fits that system and no other. The PowerTube 800 is the largest current smart-system in-tube pack. It needs a frame built for the 800 mount and does not drop into a bike designed around the 625 or 750.
Confirm the mount and the Bosch smart-system round charge port on your own frame, because packs that look identical across generations do not always interchange.
