This is an innovative tuning tool with a practical double function which has never been seen before. The DoubleDongle comes with only one set of cables, but two dongles:

One dongle increases the maximum engine support (just as usual) from 25 km/h to 50 km/h, while the other dongle, also known as the "limiter", reduces the maximum motor support from 25 km/h to 18 km/h. So you have 2 dongles to make your E Bike either faster or slower. Thanks to the pluggable design, you can switch between the two options within seconds. By completely pulling off the dongle, your electric bike´s original riding characteristics will be restored immediately.

The operating principle of the DoubleDongle is simple but ingenious:

After the cable set of the DoubleDongle is installed and the respective dongle is inserted, the following happens: From a speed of about 20 km/h, the "tuning" dongle halves the speed transmitted by the speed sensor, so that the maximum engine support is doubled from 25 km/h to 50 km/h. The "limiter" dongle, on the other hand, doubles the transmitted speed, so that the height of the maximum engine support is limited - in this case, the engine support stops at a speed of 18 km/h.

Please note that with both dongles the current speed and the driven kilometres will be no longer correctly indicated by the electric bike´s speedometer.

Some e-bikers might ask themselves the question, why should you need a dongle, which does not raise the maximum engine support but reduces it? However, there are cases where this can make much sense, for example:

- For the elderly or insecure drivers, a speed of 25 km/h can be subjectively already too fast.
- Especially for small children it can be very useful to reduce the maximum engine support for safety reasons.
- On journeys in busy city centres.
- During training rides on e-mountain bikes in difficult terrain etc.

The installation of the DoubleDongle tool is simple and can be done without any problems (even for non-technical users). In principle, the cable harness simply has to be connected in parallel to the line of the speed sensor.
