Our Yamaha Tuning (de-restriction) Kits remove the 15mph assistance cut-off on all Yamaha powered eBikes
The Yamaha tuning kit we use differs by model year. Since 2017, we've exclusively been using Speedbox products. Prior to 2016, we used a different proprietary kit which can be unplugged by the user.
This covers the Yamaha PW-SE, Yamaha PW-TE, Yamaha PW-ST, Yamaha PW-X and Yamaha PW-X2 motor systems.
We dont yet know if this will work with the new Yamaha PW-X3 motor systems due to be arriving on some of our new 2022 Haibike models. This section will be updated if incompatible, or removed if compatible, once the first bikes have been tested and approved.
The Speedbox kit is activated/deactivated using the "LIGHT" or "WALK" button on the handlebar controls. Full instructions on the use of the currently supplied system can be found here. The unit is connected directly to the motor wiring and fitted inside the frame of the bike, normally inside the outer plastic motor housings.
This product is exclusively available to customers who purchase their bike(s) directly from E-Bikeshop. We do not supply, fit or ship this product for bikes purchased from other dealers.
To find out more about why we don't supply parts or provide support for bikes not purchased from us, please see our F.A.Q page here.
PLEASE NOTE: UNLESS INSTRUCTED BY US PRIOR TO ORDERING, IF YOU PLACE AN ORDER FOR THIS PART AND IT'S NOT ACCOMPANIED BY A BOSCH DRIVEN BIKE IN THE SAME ORDER, THE ORDER WILL NOT BE FULFILLED AND YOU WILL RECEIVE A REFUND WITHIN 48 HOURS, MINUS AN ADMINISTRATION CHARGE.
Once installed, the tuning kit doubles the cut off speed of assistance. On early Yamaha motors, the tuning kit can be easily unplugged whenever necessary to revert the bike back to normal. On later Yamaha systems (2017-on), the tuning kit is activated/deactivated using the "WALK" or "LIGHTS" button on the handlebar control.
On earlier generation motors (pre-2016), the display will show an incorrect (halved) speed reading. Because the older generation system was less intelligent in the way it "fooled" the motor into thinking it was only going half as fast as it was, everything related to speed would be incorrect, including the miles covered.
On 2017-on Yamaha systems, the new tuning kit doesn't have this small drawback, and will show the correct speed reading and log the correct number of miles covered.
Please Note: We use references to "Yamaha" only in the sense that this product is designed specifically to work with Yamaha powered eBikes. This product is NOT manufactured, distributed or endorsed by Yamaha themselves.
This product can be added to your basket when purchasing your new bike and will be fitted at no additional cost while we build it for you, however, please note that if you do not specify this part when new and choose to have it fitted during its first free service, routine/annual servicing or other maintenance/service/warranty related work, a small labour charge will apply.
Because this product is specifically designed to derestrict the motor and so increase the maximum assisted speed of Bosch driven ebikes to more than the 15.5mph UK limit, they are strictly FOR OFF ROAD (PRIVATE LAND) USE ONLY! They may not be used on the road, cycle paths, bridleways or anywhere else where the public have access.
Due to the continued development of software by the drive system manufacturers, tuning and de-restriction products are supplied on the basis that they may only work with the software version and motor components of the bike supplied at the time the tuning kit is supplied and no warranty or guarantee is given that these will continue to be compatible with future software versions or upgrades offered by the drive system manufacturer.
