420 29T Sprocket
for eBikes, Motorcycles, Electric Bicycle, Scooters
420 chains are needed to match the tooth on this 420 sprocket, it’s thicker than normal electric bicycle sprocket, making it suitable for running at high speed in the range of 100+km/h or more. You can use a toothless freewheel adapter to mount the sprocket onto your freewheel crank or rear wheel. 29 tooth sprockets are great for torque orientated ebikes.
