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.

I have some thoughts.

I have logged about 80mi in 25 days. From 3-12mi at a time I have truly enjoyed my bike. Overall value and quality are really good. A few small things. The fork steerer is too short to adjust beyond the installed height and that is a bit difficult for someone who prefers to ride more upright. this is a minor issue and one easily remedied by a stem riser. What is more difficult to deal with is that the edges of the seat have already separated from the saddle. So after only a few short weeks my saddle insides are exposed and I have to order a brand new saddle for my brand new bike I have barely been able to ride. I am happy with my bike and overall have few complaints but these two things are kind of a bummer, particularly the saddle coming apart after less than a month.

Smooth Ride

I ordered the xs and it was a little big for me (5’1”) and I didn’t expect the handlebars to be so low but I fixed it by adding a riser. Overall, it’s a good bike for city riding and I am starting to get comfortable on it!!

Solid starter bike

Bike was easy to assemble and is great for riding around the city. I would recommend taking it to a bike shop for a safety check - even after being as meticulous and careful as possible, everything on thé bike was loose. Not the most comfortable seat and the paint chips pretty easily. Light (abt 30 lbs.) if you need to carry it up stairs on a daily basis. Single speed can sometimes be limiting, but overall it’s been a great bike.
