Does his bike have brakes? If not, is he allowed to cycle on roads / pavements?
ds wants a bmx for Christmas - all his friends have one and seem to cycle all over - as well as at local skate park. I have said that unless it has brakes he will only be allowed to use it at the skate park - and will be taken there and back by car. He is a bit put out at this (he's 14) as wants to be able to bike to / from his friends (about 4 - 5 miles, mostly bike path but some road) and to school (same distance / route).
Having brakes makes tricks difficult / impossible apparently.
