Why Bosch?
Share
Select Salsa ebikes use Bosch mid-drive motor systems. Bosch has been a technology innovator since 1886, and you almost certainly use Bosch products in your daily life. Now, the company we trust with everything from our car’s stability control to our power tools and electronics offers one of the most-trusted ebike systems on the market.
The Experience
Salsa uses Bosch ebike systems for their powerful, reliable motors, efficient batteries, intuitive displays and controls, and technology integration. Bosch Class 1* ebike systems give you a powerful 85Nm** of torque for getting up and over any obstacle, even fully loaded with bikepacking gear. Bosch’s large, efficient batteries grant you the range to wander as far as your curiosity takes you — or even farther with the range extender battery (sold separately).
The Tech
We value versatility and customization here at Salsa. Bosch’s smart system and eBike Flow App are the perfect pairing, allowing riders to personalize their experience with:
- Custom ride modes
- Ride tracking and data
- Route planning and navigation
- Security
