Hey Lee – quick question. I am on a 27+ hardtail. This is the little pump track I use. Almost the whole track is in the frame. The bumps and corners come up so fast and it is sometimes hard to not run off the edge. When I put my 4 year old on it his tiny balance bike seems to fit so much better on the track than my bike. It makes me wonder – would i be having more fun or learning faster if I used a bmx bike instead? I am very beginner – only my 4th time on a pumptrack.
