Easy braking
Harper Coaster kicks it old school with a built-in coaster brake. To stop, simply pedal backward and slow your roll.


Easy riding and maintenance
Harper is as simple as it gets. Single-speed bikes boast fewer components than multi-gear bikes, which keeps them lighter, less complicated, and easier to maintain. Enjoy an easy ride without all the bells and whistles.

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:
- Stand upright with your feet 6-8" apart.
- Using a tape measure or tailor tape, measure from the bottom of your foot to the top of the inside of your leg.
- 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.

Cheap bike, for better or worse
This is exactly what you'd expect for a ~$200 bike. Cheap components and parts, but it looks nice
