One thing you can do is, build just one quarter at 7.5 and see how it rides. Someone else may have a different opinion so take what I'm suggesting with a grain of salt or whatever. I'd go with 7 foot radius but of course it's always personal preference. The idea being peg / lip tricks over airs. 4.5 feet isn't much to land into for airs so i'd go for a steeper ramp vs mellower. at 4.5 feet, a 7.5 foot radius might be a bit mellow for peg tricks. That was great for peg tricks as well as airs. We used to do 8 foot radius on a 6 foot tall ramp. I have built a lot of quarter pipes over the years for sure.Īny pictures I would have are either lost or not in digital form.

He was a wooden boat builder so knew how to build a radius like no other dads in the neighborhood. My dad helped me build my first quarter pipe in like, 1984. I just looked at the actual dimensions and ~4ft is a super narrow landing for a spineĪnd it seems like your ramp is about ~4.5ft tall? gonna be hard to blast big airs out of a quarter that small, but def possible once you get used to your ramp. is that hip off to the side more of a landing or a launch? looks too narrow to be a fun landing, and it looks too mellow to be a good launch

personally id prefer long stretches of coping than having it broken up for a roller.ħ. consider putting the roller/noping below the wallride so people learning dont have to be afraid of casing coping.Ħ.

make the roller transitions small enough that you can still blast the transition like a coping'd quarterĥ. you will want the wall much further bakc from the coping once you get comfortable with quarter to wallridesĤ. the landing seems kinda narrow on that spine, make it wider for sloppy threes and a bit of travelling when you do the spine!ģ. i love how the spine is more mellow on one sideĢ. Super fun to ride, lots of options airing across it with nosebonks and shit on the roller.Īll that being said ramp looks like a blast dude good luck!ġ. If you are back and forth on the roll in, a park I rode recently had a roll in in the middle of a quarter that was up on a 2-3ft platform, about 3 ft wide, and the way it was done left a 3ft wide channel in the coping where the roll in basically went ‘through’ the coping in one little spot. That being said though, I do love doing Canadian footjams on rollers cause I’m hit or miss with them on coping haha.

You may end up wishing you had the full coping just for more options to ride. Casing 4.5 foot isn’t death, case it once or twice and you’ll see you won’t die lol. Getting back in from a wall a foot from coping isn’t hard at all but you might find yourself pulling away too far and landing flat with it close like that.Īlso with the roll in, you aren’t going to be airing a 4.5ft super high to begin with, 6-7 ft is where you can start boosting it a bit. Looks like a solid ramp! Another wall idea would be leaving yourself a foot or so of deck, if it’s not a vertical extension where you don’t have to pull away at all to get back in might as well go out a bit more, it’ll give you more room to work with for wall taps and everything.
