What is SpeedFun tuning ebike kit Ribelle for Yamaha PW-X, PW-X2, PW-SE, PW-TE, PW-ST motorw?

SpeedFun Ribelle is a tuning for ebikes with Yamaha PW-X, PW-X2, PW-SE, PW-TE, PW-ST motors from 2019 onwards which allows you to increase the speed of the ebike by removing the block set at 25 kmH. With SpeedFun Ribelle, active assistance is increased up to speeds that can exceed 60 km/h (info), making full use of the engine’s potential.

This ebike speed release device is designed for PW-X, PW-X2, PW-SE, PW-TE, PW-ST motors from 2019 onwards with Yamaha “sideswitch” type A display or Yamaha type C display mostly used on Ghost, Lapierre, MBK, Winora, Gitane, Bixs and many more branded ebikes.

The SpeedFun Ribelle ebike tuning always shows both the real speed and distance on the display and can be activated or deactivated by pressing a simple sequence of keys directly from the ebike handlebar control. Activation and deactivation of the device is signaled on the display.

The operating system for avoiding the number of revolutions of the rear wheel of the Ribelle comes into operation only when 16 km/H is reached, progressively reducing the communication of the wheel revolutions to the engine with a particular algorithm, without the cyclist feeling any difference in assistance. It does not intervene in any way at low speeds. This is an important expedient designed not to vary the engine intervention parameters when restarting and on steep climbs (which are the critical and most delicate moments for an engine), thus leaving the parameters studied and optimized by the manufacturer intact, thus avoiding power losses, failures or “hiccup” operations which instead occur with release systems from other manufacturers.
