Small and clear
Design meets functionality: Purion is the minimalist on-board computer for everyone wishing to have a neat look on the handlebar, 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 handlebar. Five different riding modes give you the correct support in every situation.
Riding modes
 Turbo |  Sport/eMTB* |  Tour |  Eco |  Off |
|---|---|---|---|---|
| Direct, maximum powerful support up to the highest cadences for sporty riding styles. | Powerful support for universal usage | Uniform support for long range rides. | Effective support with maximum efficiency for the longest range. | No support, all on-board computer functions can be accessed. |
*The eMTB mode, which is specially designed for Performance Line and Performance Line CX, dynamically switches between the Tour and Turbo riding modes, offering progressive motor support for maximum performance on the trail.
