135,30VAT incl.

SpeedFun RIBELLE is an electronic and smart speed release device that needs no external power.

It is designed for use with YAMAHA PW 2016-17-18-19-20 motors, to circumvent the 25 KmH speed limit and allow for an increase in its active assistance up to speeds that can exceed 60 KmH by exploiting the motor’s power to the full. The YAMAHA PW motor, compatible with Ribelle, is characterised by 4 levels of assistance you can select on the display (Eco+, Eco, Std, High) and by the presence of a USB port on the handle bar remote control.

What is SpeedFun RIBELLE?

SpeedFun RIBELLE is an electronic and intelligent speed release device that does not require any external power supply.

It is designed for YAMAHA PW 2016-17-18 engines to evade the speed block at 25 kmH allowing to increase its active assistance up to speeds that can exceed 60 KmH by fully exploiting the potential of the engine. The Yamaha PW engine for which Ribelle is suitable is distinguished by the 4 levels of assistance that can be set on the display (eco +, eco, std, high) and by the presence of the USB socket on the remote control on the handlebar.

SpeedFun RIBELLE always shows real speed and mileage on the display of your Ebike even with activated speed release.

SpeedFun RIBELLE is equipped with a self-learning system to store all the parameters of the ebike on which it is mounted. Therefore no setting is necessary. Only a short initial sequence and then you can only think about having fun!

Speedup RIBELLE is assembled in a very simple way interposing it between the speed sensor and the motor and between the Display and the motor using original connectors that do not alter the characteristics of electrical resistance and watertightness.

SpeedFun RIBELLE does not modify the electronics of the Yamaha engine in any way that can be restored at any time and in a few minutes to the factory configuration and leaves no trace of its installation either physical or even in the ebike software. This allows the guarantee and the effective commercial value of the bicycle to remain unchanged.

The operation system starts operating only when the 16 kmH is reached, progressively reducing with a particular algorithm the communication of the wheel revolutions to the engine without the cyclist noticing any difference in assistance. It does not intervene in any way at low speeds. This is an important precaution designed not to vary the parameters of the engine intervention at the restart and in important climbs, (which are the critical and most delicate moments for an engine) thus leaving intact the parameters studied and optimized by the manufacturer, and thus avoiding loss of power, failures or “hiccup” operations that instead occur with the release systems of other manufacturers.

SpeedFun RIBELLE can be activated and deactivated with a simple button sequence from the command to the ebike handlebar. A feedback is shown on the display each time the activation or deactivation status is changed.

RIBELLE allows the millimetric setting of the wheel circumference starting from 20″ for a very precise calculation of speed and distance even if you had to replace the tire with one of different section from the original. Normally this possibility is not offered by the original Yamaha system.

ATTENTION, Rebel is installable with the following limitations:

1: Can not be mounted on Haibike models with E: I-Shock electronic shock absorber system

2: Not suitable for Yamaha Sinc Drive engines mounted on Giant branded bicycles

3. It is not suitable for Yamaha PW-X and PW-SE engines

Once the SpeedFun speed release device has been installed, the electric bicycle, if exceeding the limit of 25 kmH, is equated to a moped and as such, if traveling in public places, it needs to be homologated-registered by the Civil Motorization. subject to the payment of the road tax and insurance coverage, must have a license plate, cannot circulate on cycle paths and the driver is obliged to drive with a license and must use a helmet. In addition, driving a motor bicycle equivalent to a moped that does not comply with the aforementioned provisions entails the administrative seizure of the vehicle and financial penalties that vary according to the infringement committed. The manufacturer of the speed release system declines all responsibility for any damage caused to pedal-assisted bicycles on which the device is mounted as well as direct or indirect damage to people or things.
SpeedFun – Phase B snc declines any responsibility for any anomalies caused by the anti-tuning defenses that the engine manufacturers could activate.
Remember that the modification to the bicycle could invalidate the manufacturer’s warranty.

The operation of the SpeedFun devices is guaranteed for the software versions of the ebikes released up to the date of purchase of the device itself.
If the ebike is subsequently updated with software for which the SpeedFun device has not been designed, its failure may occur.
Before updating your engine, it is necessary to check the compatibility with your SpeedFun device.
