I have just purchased a new Kalkhoff ProConnect B10 but have upgraded to the Nyon unit which was fitted by my supplier. I therefore have a brand new complete unused Intuvia Performance Line unit for sale. I will only sell the complete unit + controller. I do not have the user manual for this unit but it can be downloaded from https://www.bosch-ebike.com/en/service/downloads/. There are no fitting instructions. (The unit should be fitted by a Bosch trained fitter.) Price £90 for complet kit! Please contact me if interested.
