Lubricating the chain of an e-bike requires lifting the rear wheel to engage the drivetrain in a forward direction. This is cumbersome and can be difficult to do on one’s own. The Squirt eZ-Luber uses a turn hook to fix the crank to the chainring, making it possible to roll the drivetrain backwards, as one would on a conventional bike, to lubricate the chain effectively. This simple but innovative tool makes it easier to apply Squirt E-Bike Chain Wax to the inside of the chain, where it can best facilitate accurate shifting and smooth pedalling.
