Rolly Polly Frame and Fork Set

Build your Rolly Polly your way.

The Rolly Polly Frame and Fork Set is built from custom triple-butted 4130 chromoly with thru-axle dropouts and a UDH derailleur hanger. Designed around small wheels and playful handling, it makes a great platform for a daily commuter, travel bike, all-terrain build, or something completely custom.

Built tough enough to meet ISO mountain bike standards, with plenty of mounts for racks, fenders, and bottles.

One size fits most riders from 5’2” to 6’3”.

Raw Finish

Raw frames have a light clear coat that allows the natural steel and welds to show through. The finish will develop rust and patina over time. If you prefer a finish that stays more consistent, we recommend choosing a painted frame.
