If it sounds too good to be true, it usually is not. But this is one exception. The technique at Pedal Magic can teach anyone who is physically able to ride a 2-wheel bicycle in 10 minutes or less.
I can personally attest that it works, based on the experience of my 3 granddaughters. All it took was to review the video a couple of times to be sure we had the technique down pat. A large open space – we used an empty school parking lot on a Saturday morning – is also very helpful. Initially the focus is on maintaining balance rather than going in a specific direction. But control over direction comes very quickly, too.
