Does a Specialized M3-700 fit a Bosch Smart System (BES3) bike?
Whether a Specialized M3-700 fits a Bosch Smart System (BES3) e-bike, and the pack you actually need.
No. The Specialized M3-700 is a Brose pack and a Bosch Smart System (BES3) bike needs a Bosch pack. Batteries are proprietary per drive system and do not cross over.
| Battery | Specialized M3-700 (Brose, 700 Wh) |
|---|---|
| Target system | Bosch Smart System (BES3) (Bosch) |
| Verdict | does not fit |
| Reason | different brand, mount and charge port; Brose and Bosch packs are not interchangeable |
| What to buy instead | a Bosch Smart System (BES3) pack such as the Bosch PowerTube 500 (smart system) |
E-bike batteries are proprietary to the drive system, which is the whole point of the design. The Specialized M3-700 is a Brose pack for Brose Drive / Specialized Turbo (Full Power), while a Bosch Smart System (BES3) bike needs a Bosch pack with the Bosch mount and charge port. They do not cross over.
For a Bosch Smart System (BES3) bike, fit a Bosch pack such as the Bosch PowerTube 500 (smart system) (500 Wh, 36 V, BES3).
