...to get kids off stabilisers.
The average 10- or 12-inch wheeled bike that 3- or 4-year-olds learn on runs out of gear at the exact speed where gyroscopic precession takes over.
Just when dad or mum has accelerated junior to escape velocity, the little legs are starting to flap like fledgling wings. Said youngster needs to feel resistance at the pedals to make the connection between pedalling and staying upright, but all mini bikes are too low geared.
Ideally the gearing should be raised, but who has the cash or time for that sort of thing nowadays, even if suitable components exist? Another option is to deflate the tyres slightly to increase drag, but that would also slow the thing down and make it less stable...
