Surly Midnight Special – Comfort, Speed, and Confidence on Any Road

The Surly Midnight Special is built for riders who refuse to let bad roads ruin a good ride. Designed to shine on rough, potholed pavement, crumbling tarmac, and long gravel stretches, it’s the perfect road bike for those who wander beyond the smooth.

With its 650b road plus tires, the Midnight Special delivers exceptional comfort, traction, and control. The higher-volume rubber smooths out road chatter, softens harsh impacts, and keeps you confident when the pavement disappears. It’s fast, forgiving, and fun — a true steel steed for mixed-surface exploration.

When Surly designed this bike, they didn’t picture race-day lycra — they imagined pockets full of bananas, endless roads, and the freedom to explore whatever path looks interesting. Whether you’re tackling city streets, weekend tours, or spontaneous detours onto gravel, the Midnight Special is ready to roll.
