Details

Ride fixed or single-speed
Mantra is designed to move with you, not against you. Our signature flip-flop hub allows you to easily switch from a single-speed ride to a fixed one. Riding fixed has its advantages (including a guaranteed workout - you don't stop pedaling!) but it's not necessary to ride that way if you don't enjoy it. Switch it up again with a flip of the rear wheel to get back to single-speed.

Repels dirt and grime
What is a "sealed cartridge bearing hub", you ask? Only the best thing since sliced bread (although, bread is pretty great). Sealed cartridge bearing hubs are a game-changer for any city rider. This feature protects delicate parts of your bike from damage that can be caused by gunk in the road. They also require less maintenance compared to their loose bearing counterparts.

Stylish and practical
Mantra's sleek steel frame and bold machined braking surface speak for itself in terms of style. Internal cable housing helps protect and keep your cables in place so there's less getting in the way of you and your ride.
