What does the Speed De-Restriction Device Do?

The Badasse-Bike Device is an easy to fit de-restriction dongle. This clever little device will work magic with your electric bike speed sensor removing the 15.5mph LEGAL limit, allowing you to unlock the full potential of your e-Bike. The maximum speed will vary depending on the system and the e-bike, although we have seen maximum speeds in excess of 31mph. 


 Easily installs to the most popular Crank Drive e-Bike systems. 

What eGroupset does the Badasse-Bike Dongle work with? 

  • This quick and easy solution can be fitted to the Bosch Active, Bosch Performance (CX), Yamaha, Shimano Steps, Impulse, Brose and Continental systems.
SHIMANO UPDATE JUNE 2019 - There are compatibility issues with shimano update 4.7.0 - as long as you are running a version before this the dongle will work.


How does the chip tuning device fit?

This versatile little dongle can be easily fitted in a matter of seconds. In three easy steps. Slide the device over the Magnetic Speed sensor, usually located on the left lower chainstay of your e-Bike. Swap the standard phillips headed screw on the Magnet, located on a spoke in the rear wheel, with the new butterfly headed screw provided to easily move it around. Relocate the Magnet into the location shown in the Manual. It couldn't be any simpler.  If you have a restricted amount of space between the sensor and the spokes, you may be required to fit this adapter. Removing the dongle will return your e-Bike to its legal restricted speed.

 Restrictions to De-Restrictions.
