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.
Charging status, speed, riding mode, range, trip distance, total distance.
The backlit, non-glare display allows you to read all riding data clearly, even in direct sunlight.
The optional service interval display reminds you to fix the next service appointment for your eBike with the specialist dealer.
The specialist dealer can monitor the status of your Bosch eBike System via the micro-USB port.
