When I reached 12 I got a paper round, & went to new school.
Dad's old 1947 Raleigh Sport was overhauled & rebuilt as a joint project
I sat on bike & scooted around garden, then on a smooth tarmac back lane, for about a week
Then encouraged to ½ turn and 'ratchet pedal' steadily increasing up to ¼ turn to full rotation as I coasted along, having already mastered Stage B (balance) in the 3-stages of learning to ride a bike (Stage C - controls = braking & steering on balance bike or walking with a bike)
The final stage - Action is connecting stage C-B & A as riding a bike
Stabilisers are 'Haram' to borrow from the Arabic (the antethesis of Halal!) they should be called DE-stabilisers as a child can set off at speed without any experience of steering or braking, then a sharp turn will send the child face-first into the ground, something where a bike helmet can often enhance the facial injuries, as the BBC guest Jonathan Shepherd describes here https://www.bbc.co.uk/sounds/play/m0028swp fcrom the factual and objective records of cycling injuries. This is where a face plant does harm enhanced rather than prevented by a helmet, potentially to the extent of severe damage to vertebra C1-C5 (thoracic) where a C1 fracture = death or quadroplegia from damage to spinal cord/cerebral cortex. For brevity, a detail I'll describe elsewhere
I used the C-B-A method to learn to master riding an ordinary bicycle at Drumlanrig where at last there was a 60"wheel machine to use
Stage C - scoot the back-step & 'get the 'feel' of steering &c
Stage B - scoot & rise up to sit on the saddle only & coast
Stage A - scoot, sit on saddle & put feet on pedals to turn the wheel, remembering that this is a direct drive - no brakes required & when you stop pedalling you have to be ready to dismount
Also worth listening to 'Dough' https://www.bbc.co.uk/sounds/play/m0028tzr with some useful comments from sensible people!
Including Pashley Cycles, Whyte Bikes, Bicycle Association
So much more to do & since Cycling UK dumped their independent specialists, I've been struggling not helped by a desperate need to find a lawyer to take on a civil action that I am not eligible for the established systems of legal aid
It is desperate - please PM on this & the other issues
