Rolly Polly Complete Bike
Meet the Rolly Polly. We took everything we loved about the Itty Bitty and dialed it up: custom triple-butted 4130 chromoly tubing, stiffer UDH hanger for snappier shifting, beefy thru-axles, two piece 165mm cranks, and fast-rolling hubs loaded with secret Japanese bearings. It’s tough enough to pass ISO mountain bike standards, but still cute enough to turn heads.
The Rolly Polly sticks to our design roots: no carbon forks, no internal cable nightmares... just a simple, durable, fun-first frame that’s easy to wrench and ready to rip. With a slightly longer seat tube for taller riders, a tweaked wheelbase for more playful handling, and our signature SWAG (small wheel adjusted geometry), this is the bike for underbiking with maximum style. Whether you're commuting or causing chaos with your crew, Rolly Polly's got your back. Let's see how far you can push this adorable little monster.
One size fits most (5’0” to 6’3”). Our frame geometry grows as you raise your seat height. This allows for a full range of rider sizes just by adjusting saddle height. (Standover height is 698mm or 27.5” from the ground. Stack is 496mm and reach is 390mm. Top tube length is 545mm. Seat tube length is 440mm.)

Our raw metal frames are finished with a light clear coat to show off the material, but they will rust and develop patina over time. It’s a lived-in look that show cases our welds that we love. If rust isn’t your thing, we recommend choosing a painted frame instead, since raw finishes aren’t for everyone (and that’s okay!).
