What is the bikespeed-key?


bikespeed-key (Bosch Pedelec Tuning) bikespeed-key is a simple and compact kit consisting of a tuning-chip and a cable set to bypass the speed limit of 25km/h in Bosch or Yamaha Pedelec engines. The chip halves the speedometer from a velocity of about 20km/h. This way, the scope of the support provided by the engine is enhanced to a maximum of 50km/h.

As long as the bikespeed-key is not plugged in your e-bike will work as normal. The “turbo gear” is activated as soon as you plug in the bikespeed key.

After installing1) the cable set, which is simply connected parallel to the speed sensor, the chip can be plugged in and out at any time (even while riding).

The cable set included is long enough to place the bikespeed-key anywhere on your bike. The cable set can simply be shortened to the length desired.




Why choose the bikespeed-key?

The greatest advantage of the bikespeed-key is its simplicity for you, the user. We eliminated any problem in the run-up to the development of the bikespeed-key. You merely have to spile two cables, or stuck between using our optional plugable cable set, and the tuning will be finished.




Does the bikespeed-key suit my bicycle?

Do I need a special tool for the installation?

Why are there different cable sets of the bikespeed-key on the bosch engine?

You can shorten the cable to the length required. The USB-cable is to be plugged into the speed-sensor of your pedelec. We provide you with terminals with insulation sleeves which enable a solderless connection.

A further advantage is the foolproof and fast installation.
