In our bike shop, we had been waiting for a solution to mount the Bosch Kiox 400C display on non-compatible frames for our customers… and it has finally arrived. Riderwalker’s Mastermount400 is easy to install, fits perfectly, and lets you enjoy all the improvements the 400C offers. Highly recommended.
Perfect fit
This unites designed to house the Bosch 400C display, and is easy to fit to E bikes with insufficient capacity to accommodate this larger control unit. It is a must do upgrade as the 400c control/display is a massive upgrade to previous Bosch units. Riderwalker have put hours of design into this unit which can fit any bike with the new Bosch 400C control unit and link via the Bosch flow app . I recommend this Riderwalker Mastermount 400 to everyone who wants to upgrade to the 400C . John Sutcliffe LAKEDISTRICTBIKES uk
