YajingGlass Mountain Bike 12 Magnets Ebike Assistant Sensors Speed Sensor Pedal Assist PAS System: Easy installation on mountain bikes
Picture this: you're halfway up a brutal climb, legs burning, and your ebike's motor cuts out. That's the kind of headache this 12-magnet PAS sensor aims to solve. It's the brain behind the brawn, translating every pedal stroke into smooth, seamless motor assistance. With a dozen magnets in the mix, it's hyper-responsive—no more lag or jerky power delivery. That precision isn't just about comfort; it's a battery-saver, squeezing extra miles out of each charge by matching effort to terrain. For mountain bikers, that reliability is gold when trails turn gnarly. Installation? A cinch for the weekend tinkerer, no shop visit required. Think of it as the upgrade that turns a grueling grind into a graceful glide, rain or shine, thanks to its weather-proof build. In short, it's the unsung hero that makes every ride feel effortless.
