Alright, listen up all you electric bike and scooter enthusiasts! This little brake sensor cable might not look like much, but it's seriously important for your safety. Here's the deal - when you're riding your e-bike and you hit the brakes, this sensor tells the motor to cut power immediately. No more fighting against the motor while you're trying to stop, which is way safer especially in emergency situations. Installation is a breeze with the self-adhesive backing - just stick it where you need it and you're pretty much good to go. The magnet is made from quality materials that won't rust or corrode, even if you get caught in the rain. Works with pretty much any brake system you can think of - disc brakes, V brakes, drum brakes, you name it. The cable is about 68 inches long so you've got plenty to work with when routing it through your bike frame. If you're building your own electric bike or just need to replace a faulty sensor, this is exactly what you need. We test every one before shipping, and if you run into any issues, just reach out - we'll help you sort it out within a couple days.
