About Trefecta Key
After the initial bonding process of your Trefecta eBike and your smartphone is completed, you just need to get close to your Trefecta eBike to unlock it (proximity detection). You phone will automatically shutdown and lock the vehicle, once you've left about 10m. Keep the lock-symbol opened to enable the automatic function. If you tap on the lock-symbol you can also manually switch the eBike off and back on.
