The Dad Rat has been designed and built for

• Hucking kerbs on the school run

• Skimming singletrack when you’ve only got 45 minutes

• Towing the kids to class with a tag-along

• Popping to the shop like a two-wheeled dad (or mum) ninja

This frame is for the folks who ride because they love it — not for likes, not for podiums. It’s simple, fast to make, and designed for maximum good times on minimal effort. No paint options. No custom builds. Just a straight-talking frame that gets on with the job.

And you won’t be alone. Every Dad Rat rider becomes part of the Rat Colony — a loose-knit club of misfits, parents, trail goblins, and gravel gremlins. Think ride-outs, patches, challenges, maybe even the odd tattoo. It’s a bit punk, a bit practical, and fully committed to keeping bikes fun.
