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:

  1. Stand upright with your feet 6-8" apart.
  2. Using a tape measure or tailor tape, measure from the bottom of your foot to the top of the inside of your leg.
  3. 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.

This bike is fun!

This is my first single-speed bike I've ever owned. I'm happy with the product so far. I've ridden about 30-40 miles and it's a lot of fun. It has a comfortable riding position and nimble in the city trails. The pictures on the website don't give it justice. It is a well made bike for the price. I would gladly pay a little extra for disc brakes.

Bike too tall/can’t return.

The Mantra seems like a good bike, but I ordered according to the recommended heights and it was way too tall. Unfortunately, I wasn’t able to return the bike because some of the packaging material had been thrown out. I did reach out to customer service to see if there is a donation/exchange program but never received a relevant response.

Mantra Grey

Bike is great. Just had issues with the chain guard not working, but they were nice enough to send me a helmet. Some other issues were having leaks around my hub when it said in the description the Mantra and the base model is that they are secured in a way that they don't leak out and they also last longer. There is a circle rubber peace missing from the brake line and the brake handles are wobbly no matter what I do.

A Solid Bike for the Price

The Mantra is a beautiful, no-frills, single-speed bicycle. It's a little heavier than I would prefer, and I ended up replacing the stock plastic pedals with metal ones, but I'm very satisfied with my purchase overall.
