Hi, Im 14, 5'10", weigh 11 stone and I'm looking for a bike. I dont know much about trials except it looks fun (and hard). I have a budget of roughly £400 but I suppose I could go over it would just take longer. I was thinking that a 20" mod would be best. Could you tell me any good bikes that fit my budget? Would I need to replace any parts quickly or just leave it as it is? Thanks, Jacob
