M35 Free Wheel Ratchet Adapter - Right Hand Thread Hub For Sprocket Chain Wheels

If you're building go-karts, e-bikes, or mini bikes, this free wheel ratchet adapter is exactly what you need to connect your sprocket to the axle. The M35 internal thread with right-hand threading fits perfectly with standard hub adapters, and it's specifically designed for 4-hole sprocket chain wheels with 54mm inner diameter and 65mm hole positioning. What's really cool is how it works just like a bicycle freewheel - it engages when your motor is running but spins freely when you're coasting, so you don't get that annoying drag. Made from hardened steel with quality ball bearings, this thing is built to handle some serious use without wearing out. The hub adapter comes with a set screw that locks securely onto your shaft or axle, giving you a tight fit that won't slip under load. These work with #25 roller chain (that's the 1/4 inch pitch stuff) and the nickel-plated steel sprockets look professional while resisting rust. Whether you're building from scratch or upgrading existing equipment, this adapter makes the whole drive system work smoothly. The quality is noticeably better than cheap imports - you can feel the precision machining and solid construction. Definitely a must-have component for any small vehicle project where you need reliable power transmission with freewheeling capability.
