Anti-theft GPS tracking gives you piece of mind

The onboard e-bike computer is the latest must-have piece of cycling technology. It not only calculates your position and speed, but also features peddle assist sensors and an automated motor sensor, so you can get the most out of your ride. The integrated gyroscope ensures that you stay on track, while the anti-theft GPS tracking system keeps your bike safe and sound.

The integrated gyroscope ensures that you stay on track, while the anti-theft GPS tracking system keeps your bike safe and sound. Of course, you should take all the necessary security steps including using a suitable lock. An extra level of security is provided when you activate the locking function from your smartphone. This disables your motor and activates an alarm should your converted ebike be moved. Should it be necessary, your bike can be tracked when the battery is used using the inbuilt GPS tracking.

Anti-theft tracking scenario

Carl had been grabbing his breakfast on a crowded street in London. He was balancing his coffee on top of a garbage can and chatting with some friends when he realised his bike was gone – vanished.
