jiatongdiji Durable Mountain Bike Pedal Assist System: 12 magnets for precise sensing
Ever wish your e-bike could read your mind on a grueling climb? The Durable Mountain Bike Pedal Assist System is the tech that gets close. This sensor kit slips onto your ride, delivering buttery-smooth power boosts exactly when you need them. It’s all thanks to 12 precision magnets that track every pedal stroke, so the motor responds to your effort—not just a clunky throttle.
Built for trails and commutes, this PAS is a battery-saver’s dream. It only kicks in during pedal action, and a speed sensor keeps pace with your every move. Tough enough to laugh off off-road jolts and vibrations, it mounts simply on the crank and chainstay. The result? A ride that feels more like an extension of you—effortless, intuitive, and seriously fun.
