Hearing of the lack of balance ability, I'd want a written guarantee for the $60 course that says if he can't ride in the end, then they will do it again and again at no extra charge till he rides like a pro.
Teaching bike riding in the rain though.... I guess if you rarely have a sunny day, that could be excused.
Good Luck.... !
I think there is actually a bit that says if he hasn't mastered it they will enroll him on the next one. I haven't given up quite yet tho. I am gonna try wrapping a sheet or a towel round him and see if I can save us cash!!
Maybe he's just not ready yet ! When I was growing up, we wanted to ride because the older children were riding and we just kept trying till we got it. There were some training wheels that some folks could hook on the back wheel of the bike that kept it from tipping over, to use for a while till some children got a better feel for it. Don't know if anything like that exists anymore.
I am actually thinking that maybe he isn't. He might just need another year or so or even a few more months pottering around on it without cycling. I will reassess as the weather gets better. I dont want to stress him out about it!
