Afternoon guys. I need some advice on how to get started with trials biking. What would be the best type of bike to buy ? A pure trials bike ? or more like an urban jump bike ? Whats the best size wheels ? I see there can be a choice between 20/24/26 ? Not sure how much I want to spend, but look at 500 quid as a starting point. I mountain bike alot, and I think if i did a bit of trials practice it would help me on the trails Also a question thats been in my head, is the front ring fixed on a trials bike ? (what I mean is if you pedal backwards the bike moves backwards .. not sure if im being clear) Any way, any advice / pointers would be greatly appreciated !!! Cheers NB
