Are those 700c tires? Interesting..... 700c has the same bead seat diameter as 29'er mountain bikes, it's just that 700c tires are lower profile.....

No offense to that particular bike...but....it's no PumpTrack weapon.
I'm sure It'd be fun enough for a workout on a tame PT. But on a more aggressive PT with jump rollers
and such its just wrong.
You'd have way more fun on a 26 or 24 bike with proper geo.

yeah, i agree, an aggressive pump track maybe not great. but a basic one, i think he'd be able to cruise around it like this:

that guy is just cruising through it, not blazing, not jumping, not manualing.....

Mellow pump track, and i'm pretty new to it. I ride trails on my S.C Bronson, and wasn't getting much use from my Sub10, so thought it would do the trick for now.

Cool then. Probably be perfect for building PT skills,endurance.
Then when you're ready to amp it up build another one.

The Jackal looks pretty sweet! do you typically drop a frame size? I'm 5 10ish, and like riding smaller bikes, so guessing i'd go for a M.

Not necessarily. DJ frames are already sized for DJ. All the seat tubes are low, and the main question is the top tube length.

It doesn't help that there are several ways of measuring the front end.

MTB, Road, etc. often use "Effective Top Tube" which goes up to a theoretical seat height. I wish they wouldn't do this with DJ bikes, because no one has their seat up there.

BMX and some DJ frames (like Black Market, etc.) are measured using a center-to-center along the top tube, or Actual top tube.

In the DJ world, it's fair to say that 21.5"tt (actual) is Small; 22" is Medium; 22.5" is Large; and 23" is XL.
