Patterson165_B

Patterson 2 Speed Crankset modified with a 12 Pole PAS sensor on the left crank, and a larger 39T chainring and CNC machined chain guard on the right. This gives the equivalent of a 62T front chainring size in the high gear, allowing you to keep a reasonable pedal cadence even at very high travel speeds, perfect for fast ebikes or bike builds with small 20" rear wheels. The chainring freewheels as well, making it useful in custom mid-drive projects too.
