Pump track layout by Siphin posted Aug 28, 2017 at 8:41 AM Hi everyone. I'm new to the forum but not to bmx and dj. I haven't rode in about 12 years (kids and life!) well anyway my boys are 9 and 7 and I'm starting a small backyard pump track in out back yard. I got a out 4900 Sq feet of space to throw a track around. But I have to leave anything that's existingbin place (wife's rule). I want to build a decent one and have never built one before. Back in the day I helped dig a few and maintain a few but didn't do any of the fine tuning. My boys are really wanting to get into BMX pump tracks and I'll admit it rekindled my passion for riding. So while I'm waiting to get a bike I figured I could build a track. So far I have a couple little rollers and a start to a Burm. I sketched out the area last night and this is what I came up with. Any thoughts or ideas will be greatly appreciated.
