Bikes. Parts. Chaos.

Ice Cream Truck is the bike we reach for when we don’t really know what the trail has in store.

The Largest Tire Clearance on a Fat Bike Frame

From log and root covered ribbons of twisty singletrack to miles of powdery snow or sandy beaches, Ice Cream Truck can handle it all. Hell, you could probably even hop over a grizzly if the situation arises. Probably.

While we could certainly throw out terms like “confidence-inspiring” and “traction-laden” to describe Ice Cream Truck, those phrases are mostly bullshit, so we’re not going to do that. We’re not here to inspire you, and we didn’t laden it with anything. What we did do was design a monolith of a trail bike that doesn’t give two shits about what’s in front of it.

  • Long toptube, short seatstays, and a 68-degree headtube angle makes it tight and maneuverable on fast, technical terrain
  • Modern trail bike standards like stealth dropper post routing, 44mm headtube, and thru-axles
  • Clearance for a full 26” x 5” tire on 100mm rims

  • 5/5 with Snow and Sand Snow and Sand: 5 out of 5
  • 5/5 with Singletrack Singletrack: 5 out of 5
  • 4/5 with Bikepacking Bikepacking: 4 out of 5

NOTE: You can ride your bike wherever the hell you want, but this is what we think this bike is best at.
