A sleek stealth diamond frame for faithful adventure-hopping. This zero-hassle, belt-driven, super commuter is always ready. Finally a bike as fearless as you. All Studio bikes come standard with:

INVINCIBLE. AIRLESS TIRES. FLAT FREE FOREVER: We designed our bikes with a built-in super power. Meet Muffin® tires. With more than half of their interior filled with a natural, stable gas, integrated with macromolecular materials, Muffin tires will never need air - and never go flat. They are weatherproof. Wear-proof. Skid-proof. And dare we say, invincible.

SLEEK, FASHION FRIENDLY, BELT DRIVES: Chain free, grease free, fashion friendly, belt drives. With industry-leading Gates® Carbon Drive belt drives, you can leave the grease and grime to the streets. Quiet. Sleek. Fashion-friendly. Zero maintenance.

INCOGNITO GEARS: Nexus 3-Speed Internal Hub: We've protected the gears, so you can step it up a gear - incognito. Weather-friendly. Incredibly low maintenance.

STOPPING POWER: Our completely sealed-from-the-elements Shimano braking system gives you reliable, zero-maintenance stopping power. All bikes come equipped with Front and Rear Shimano® Roller Brakes.

READY-TO-FLY SHIPPING: We deliver a 99% assembled bike to your doorstep so you are ready to get out there and fly at a moment’s notice.

I've been watching the evolution of tire technology. These tires are really amazing. I ride with my bike everyday to Frost Science. Fear of flats is always an issue. It's great to remove this obstacle.

Now I have the flexibility to go ride to the park for 45 minutes and re-energize. Come back mentally super powered. And I can go when I want now without worrying about grease.
