Black Friday Doorbuster Speedfun Furious Evo Ebike Tuning Kit For Brose Sram (mechanical Shifting) Set [bl7m86Lp]

This SpeedFun Furious is a tuning kit for eBikes powered by a Brose SRAM motor with mechanical shifting (excludes models fitted with AXS wireless shifting).

Once fitted, it will remove the factory 15mph or 20mph speed limit. Giving you a derestriction up to 28mph (45kmh). The tuning kit is turned on/off by activating the lights via the SRAM AXS app. 

Please note, speed readings above the factory limit will not be accurate. If you require accurate readings at all times, we recommend fitting a third party display to track your speed. 

If your bike is fitted with an electronic derailleur (eagle transmission), the auto shift feature will need to be disabled when the speed unlock function is activated
