superlative82 Posted November 3, 2019 Report Share Posted November 3, 2019 Hey All, just after some general advice on getting my son his first trial bike. He is just starting out and has had a handful of lessons and is now moving onto trials lessons. For a 9 year old what is the generally the first trial bike they move onto? Thanks in advance Quote Link to comment Share on other sites More sharing options...
breagh Posted November 3, 2019 Report Share Posted November 3, 2019 Hi there choice is fairly limited,either an Oset 20r or a Beta 80 small wheel. I've both, Oset needs a lithium battery to be any use which makes it expensive and it has limited off road ability. I find it fine for playing, Beta's more up for it,rides like a proper small trials bike which it is, weak point is the hubs, holds it value well and quite sought after. 1 Quote Link to comment Share on other sites More sharing options...
