Ride fixed or single speed
Mantra is the best-of-both-worlds bike. Stick to single speed, or switch to a fixie with a flip of the back wheel for a guaranteed workout.


No thanks, dirt and grime
Mantra has a sealed cartridge bearing hub, which protects delicate bike parts from gunk in the road and require less maintenance than their loose bearing counterparts.

What's My Size?
Your inseam can help you find the perfect sized bike (measuring it properly is similar to pant inseams but measured a little differently). Here's how they work:
- Stand upright with your feet 6-8" apart.
- Using a tape measure or tailor tape, measure from the bottom of your foot to the top of the inside of your leg.
- Compare your inseam measurement to the standover height of the bike. You should have about an inch of space between your body and the top tube.

Smooth Ride
After about of a month of riding, I can say this has one of the best bikes I've ridden. Very light so it's easy to carry when necessary.

Mantra Single Speed
The product came in pristine condition, it was easy to assemble, and fits with my height. The color scheme is what I went for and love it.
