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.

Mantra 7s

While the bike itself is fine, it arrived nearly three weeks late and was damaged. Some of the spokes were bent/disconnected, and the seat clamp was broken.

Great bike so far

Looks nice, very modern. I love the rims. The only complaint is that this size is slightly big for my wife, she wishes they came in 47cm size. And she's 5'2
