SO14: The Greatest Pit Bike Ever Built

Disc Brake BMX Pit Bike

The term pit bike has its roots in motocross, where people often use small childrens’ bikes to cruise between the various staging areas at races. The term is now used to describe any variety of small childrens’ bicycle or motorcycle used to cruise the pits or injure yourself while drinking and dicking around.

While the renaissance of pit bikes was in the early-2000s, when even bicycle manufacturers like Foe’s Racing jumped on the trend and created trick components for the tiny tot motorcycles, it’s rare to see anything particularly spectacular these days. So we were incredibly impressed by the little red kids’ bike lurking in the Hayes Booth.

Can you spot what makes this pit bike so special?

STem Routed Disc Brake BMXDesigned by Jon Wells,  an accomplished racer and freestyle rider, the bike was custom built to fit his giant frame. The TT is an almost unheard of 22″ and the chainstays are also on the longer side, because of his racer boy background. 

The hydraulic brake cable is routed through the stem and internally through the fork to give Jon the clearance for bar spins and X-ups.

Disc Brake BMX Pit Bike 2While some BMX manufacturers are starting to play with the concept of disc brakes on race BMX bikes, Jon decided to go full goon mountain bike. In addition to front and rear brakes, the bike has a tapered headset and a 15mm fork with a  Maxle QR.

I definitely hurt myself with some drunken shinanigans at sea otter this year on my “pit bike”

Damn wheelies and pump track…

Such a cool bike!

You’re not the only one….BMX bike + XC Descent….

Uhhh…: “the Renaissance of pit bikes was in the mid-20s.”

What does this mean? the mid 1920s? The author’s mid-20s?

I imagine that Saris Mercanti, the author, meant to write “mid-2000s.”

Who’s editing this stuff? Anyone?

SamSkjord - 04/14/14 - 5:42pm

You’re right JasonK, I demand my money back!

Dan - 04/14/14 - 5:45pm

If you were paying a subscription, I could see why you would care so much.

The hobby store called.

Thanks, Saris.

Not to nit pick, but the mid 2000’s would be around 486 years from now…..

While I admire the creative genius and the insanity in some of these bike’s uses, and the gadgets, gizmos, and newest thingy’s…I say thanks for the share!
I am a 52 y/o Diabetic w/ a WALMART Mountain bike that was going curbside. I took it and with a little TLC and scrubbing that I use for leisure riding to fishing holes, minor trail exploring, and pedaling My old butt back into better shape. (i found out smoking and biking DO NOT work well together…DUH GRINS)
Reality of things, while I will probably never have any of these fantastic bikes, and economics aside, I highly admire the engineering creativity and brilliance along with the astonishing skills and feats riders push these creations to.
Thanks for the info, the posts, and the chance to say thanks.

@stratosrally, the tread looks like a Vee speedster….have non whitewalls on my kids mini and my cruiser, good modern BMX tires.

GXP bottom bracket? GXP is a crank axle size – not a BB size. If anything, that thing probably has a standard BMX bottom bracket with an adapter that fits GXP cranks.

its titanium folks …. :-)

ISCgee - 04/15/14 - 12:22pm

suuuuuper nitpick time: I don’t think those are ISCG05 tabs. ISCG05 Tabs are not flush with the end of the frame BB shell, they are 2.5mm recessed toward centerline.

other than that, its an interesting bike.

Jonwells - 04/15/14 - 4:08pm

Hey guys! The ask for check out my new bike.
The bottom bracket is BB30 press fit
The rear spec is 12×142 and the fork is 1.5 taper.

The only thing missing to make it the “ultimate” pitbike is

bob-ri - 03/11/15 - 4:39am

this is truly wonderful, want it and hope this will be a standard soon. anybody to say how to get the fork please? one thing: bar spin? (if was able) I would go for not hydraulic on the back and gyro or likes…hammersmith crank for clearance? thank Italy
