Speedbox 2 for Bosch Gen2 or Gen3
Speed Box 2 for Bosch is a microprocessor controlled tuning tool which takes away the 25 km/h speed limitation of your electric bike´s drive system completely. This means, you can much faster with full engine support. The device is compatible with Bosch Active Line, Performance Line and Performance Line CX drive systems (Gen2) or Bosch Active Line Plus drive system (Gen3). A great advantage of this tuning tool is that your display (INTUVIA, NYON or PURION) will still show the real speed! Other relevant data like distance, range, maximum and average speed will be shown correctly, too.
Important hint: Only the km/h (kilometres per hour) values will be shown correctly, not the mph (miles per hour) values (mph will generate errors).
You can conveniently activate the Speed Box 2 by a short press on the WALK button (it´s placed at the head of the control panel). If you press the button, for about 3 seconds a current speed of 9.9 km/h will be shown. This shows you that the Speed Box is activated and the engine support works up to 99 km/h from now on. If you press the WALK button again, a current speed of 2,5 km/h will be shown. This means, the Speed Box is deactivated and your electric bike works like it did before (with motor support to 25 km/h). Hint: If you turn off your electric bike, the Speed Box 2 will be deactivated, too. That means: If you turn on your electric bicycle, the SpeedBox2 is always deactivated.
The Speed Box 2 only consists of high-quality components manufactured by globally known manufacturers. The microprocessor which controls the device has even been certified for the automotive industry.
The installation of the speed box 3 module is very easy and uncomplicated:
- At first you have to disconnect the battery from your electric bike.
