    Measuring Inseam

    Inseam is the most important metric to consider when deciding on bike size. In order to take this measurement properly, follow these guidelines:

    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.

      A Solid, Light Bike

      This bike has been solid, it speeds on by on the skinny tires. Only problem i had was the rear inner tube bursting after the first few rides, and the chain slips off going down one hill in particular. Not good over bumps, but smooth and in particular, flat paves cruise. Very bare bones but i love it for my everyday commute.

      Nice, simple bike

      I like this bike. Single speed and coaster brake. Simple. Have to put it together and it is not hard to do. Actually took it out for a spin even though it is already getting cold up here in Michigan. Nice and smooth, just like I remember my old bicycle. It looks really nice. I got the XL and I'm 6'2" and it is almost too large. I didn't put the seat up at all. Parts are well made, construction is good (except for the flimsy, plastic chain guard which I couldn't get mounted anyway). Excellent value. In stock when I wanted it. Shipped in a timely manner. Thank you Retrospec!

      Great Bike!

      I love my bike. Quality is outstanding and I get a lot of compliments on the look. Single speed is tough with the Georgia hills but I knew that beforehand because I purchased the bike for workout purposes. Very happy with my purchase. Important to note, I'm 6'5 and the XL fit perfectly. I would not recommend an XL if you are below 6'2.

      Not bad for the price

      Some broken plastic endcaps for the hubs when received and the chain guard is cheap and unusable. Other than that the ride is a bit bumpy but simple and fun to ride.
