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.

Well built basic bike

If a bike could be "commercial grade", this one would be it. Everything from the frame, brackets, chain, handlebars, wheels, wide pedals, are stout. Coming in at 34 pounds, it's still a reasonable weight. Rides smooth. Seat is comfortable. Single speed still challenges the legs on hills, but this one is not as tough to pedal as others. This bike is somwhere between a light coaster and a light mountain bike. Does well on gravel and grass. Very pleased.

Like a kid bike for adults

This has been a good bike so far. I love that it’s a simple single speed bike, reminds me of the BMX style bikes I rode as a kid. The geometry is a little off though, the seat slides you forward whereas I feel like it would be more comfortable if it had a sling back seat post. All in all it’s a well built bike

Great product.

Product seems well made and the matte black finish is nice. Bought this for my daughter and she loves it...butjj no I ride it as much as her. Shipping was very fast and everything arrived intact and without blemish.

This bike is solid but not too heavy, easy to ride, love the look at it. I was a little worried about not gears but it has not been a problem at all! LOVE!
