Small and clear
Design meets functionality: Purion is the minimalist on-board computer for everyone wishing to have a neat look on the handle bar, be it for use in the city or the countryside. You get all important information conveniently at the touch of a button during the ride, with both hands remaining on the handle bar. Five different riding modes give you the individually correct support in every situation.
Riding modes
 Turbo |  Sport/eMTB* |  Tour |  Eco |  Off |
|---|---|---|---|---|
| Direct and maximum powerful support up to the highest pedalling rates for sports riding. | Immediate, powerful support for sports riding on natural terrain and even in city traffic. | Uniform support for long stretches, with clear focus on long ranges. | Effective, but gentle support, designed for maximum efficiency for long ranges. | No support, Purion continues to provide all important information. |
*The eMTB mode, specially designed for the Performance Line CX, dynamically varies between the Tour and Turbo riding modes, progressive motor support for maximum performance on the trail.
