### Re: flat bottom length-vs-transition radius and height

I built a 4ft wide halfpipe 2ft tall and an 6ft flatbottom it works fine. the flatbttom is just perfect. Can't grind but is nice to learn tricks on, you can 50-50 it. Its so awseome!

### Re: BMX

I'm not great but I've been riding for a little while and I've ridden a 5' quarter with a 5' radius out of concrete and it works but not great. Mini ramps aren't good because the radius is way to much for a bike and its hard to air out of and stall because of the radius.
