  • The VOLspeed V4 Bosch is the latest generation of this popular tuning chip. The casing of the module is even more robust and comes with extra functions. Now even more robust and with a greater range of functions than ever before. VOLspeed V4 is not only compatible with most previous Bosch E Bike engines, but also with the new Bosch 2022 (Gen 4) drive systems. 
  • The VOLspeed tuning kits are one of the most popular e-bike tuning devices on the market. Their popularity is due to their unique engine optimisation feature that allows to reduce the annoying ‘wall effect’ of the engine when reaching maximum speed. This tuning dongle completely unlocks your engine to 28mph (45km/h). Another appealing feature is that the speed limit can be adjusted for reduced battery consumption. With the tuning active all data on the display remains accurate. 
  • The tuning hardware is completely encapsulated and protected by a rigid casing which guarantees for toughness, impermeability, and thus hardware longevity. The VOLspeed is manufactured in Germany.
