Features
Durable Steel Frame
High-tensile strength steel is tough, resistant to fatigue, and shock-absorbing-a must for city riding.
Single Speed
Single speed bikes boast fewer components than multi-gear bikes, which keeps them lighter, less complicated, and easier to maintain.
Commuter Tires
Grooved tires grip the pavement and dispel water for solid traction, rain or shine.
Coaster Brake
To stop and take in the views, simply pedal backwards.

How to measure my inseam for a bike

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.
SizeHeight RangeStandover Height
43CM - XS 5’5” - 5’7” 29.5"
49CM - S 5’8” - 5’10” 31"
53CM - M 5’11” - 6’0" 32.25"
57CM - L 6’1” - 6’2” 33.375"
60CM - XL 6’3” - 6’5" 35"
