  • The Midnight Special is a road plus bike designed to provide comfort and speed on those all-day rides that extend well beyond fresh pavement. It excels on pot-holed, deteriorating pavement and the occasional long stretch of gravel. With 650b road plus tyres The Midnight Special eats up road chatter and absorbs all the bumps in the road for a much more comfortable ride.
