The ST2 offers braking assistance for longer descents.
- For this, press and hold the minus control button for 2 seconds.
- Briefly press the plus or minus control button to adapt the braking power of your ST2.
- To end regenerative braking, press and hold the + or - control button again for 2 seconds.
- Regenerative braking is also terminated automatically if the speed falls below a specified minimum and you start pedaling.
The current strength for regenerative braking is a maximum of 15 amps. To protect the battery, regenerative braking is reduced as battery charge increases. This means that when the battery is almost fully charged, regenerative braking is barely or no longer noticeable.
