Midnight Special is a road plus bike designed to provide comfort and speed on those all-day rides that extend well beyond fresh pavement.

Midnight Special shines on pot-holed, deteriorating pavement and the occasional long stretch of gravel. Its 650b road plus tires eat up road chatter and absorb all the bumps in the road like the champion it was designed to be.

When it comes to road bikes, we just want to toss a few bananas into our pockets and see where the road takes us. We seek out varied surfaces on our rides and frequently go from pavement to gravel to shittier pavement. Midnight Special allows us to accomplish all of that quite comfortably.

Higher volume tires allow better fine tuning of tire pressure on varying surfaces and create a wider contact patch for increased traction
Modern road standards like flat-mount disc brakes, 12mm front and rear thru-axles, and a 44mm head tube
Clearance for 650b x 60mm or 700c x 42mm tires without fenders (650b x 50mm or 700c x 38mm with fenders)
