SpeedBox 1.6 B.Tuning for Bosch Smart System Gen 5 + Rim Magnet

For the latest generation. The SpeedBox 1.6 B.Tuning removes the 25 km/h assistance limit on Bosch Gen 5 Smart System bikes with rim magnets — the newest CX and CX-R motors — with Bluetooth and full SpeedBox App support including real speed, adjustable limits, invisible tuning and over-the-air updates.

Compatible with: Bosch Performance Line CX and CX-R 5th generation, motor model BDU384Y. If your Gen 5 bike uses a standard spoke magnet, the SpeedBox 1.1 covers it — ask us to confirm before ordering.

Keyed connectors, reversible install, lifetime functionality warranty. Fitted at the Grace and Pace workshop, Alphington.

Important: private property use only — a tuned e-bike must not be ridden on public roads, paths or trails in Australia. Tuning may affect your bike manufacturer's warranty. The rider is responsible for complying with all applicable laws.
