If you have a heavy motorcycle, it’s easy to find yourself parked facing down a hill, towards a fence, with no way to move the bike backwards.
Today’s invention provides your bike with an emergency reverse gear.
With the bike on the centre stand, wedge the roller under the rear wheel.
Attach two ratchet straps to the centre stand hinge and tighten.
Sit on the bike and gingerly let out the clutch, so that the rotation of the rear wheel drives the roller and the bike moves a metre or two backwards, allowing your escape.
The system is small and light enough to fit in a topbox.
