If you own an E-Bike, then youll know that cleaning and lubing your chain is a tricky business, as the crank doesnt spin backwards like a regular bike unless its flipped upside down – which can scratch components. Our new E-Bike precision-machined Crank Tool contains three different sized tool bits which snap into place with a magnetized connection, all wrapped up in a durable CNC machined 6061 aluminium body. It fits straight onto a chain ring, so the crank can be spun backwards, and the protective silicone sleeve prevents any crank damage.
