Thumb Throttle Option

We have also made a custom thumb throttle option that will be easier to throttle for some users. There is finer control with thumb throttles.

This works the same way as the stock ZERO QS-S4 throttle except the throttle lever is pushed by the thumb instead of being triggered by the fore finger. 

Locking System

Together with the ZERO LCD, we provide 2 different integrated locking system: the ordinary key lock and the biometric fingerprint lock.

The key lock comes with 2 spare keys for you while the finger print lock enables 14 different fingerprints to be stored so you can pass on the ebike or e-scooter to be used by anyone of your choosing. 

For both locking systems, the LCD will not be activated if the key or the fingerprint locks are not unlocked.
