SpeedBox 1.1 B.Tuning for Bosch Smart System | Bluetooth

The Bluetooth version of SpeedBox's best-seller for Bosch Smart System. Removes the 25 km/h assistance limit and pairs with the free SpeedBox App for ride data, adjustable speed limits, invisible tuning mode and — crucially — firmware updates over the air, so a Bosch software update doesn't mean buying a new chip.

Compatible with: Bosch Smart System Gen 4 and Gen 5 (round connectors) — Performance Line SX, CX, CX Race. Displays: Kiox 300/500, Purion 200/400, Intuvia 100, LED Remote, Mini Remote, System Controller. Not compatible with rim magnet bikes (use the 1.3–1.6 B.Tuning instead).

Genuine keyed connectors, roughly 20-minute install with basic tools, fully reversible. Lifetime functionality warranty. We can fit and pair it for you in 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.
