Easy braking, easy maintenance
Harper Coaster sports the simplicity you love from a single-speed bike and makes it even simpler. Instead of hand brakes, Harper Coaster kicks it old school with a built-in coaster brake. To stop simply pedal backward and slow your roll.
Simple riding and easy maintenance
Harper is as simple as it gets. Single-speed bikes boast fewer components than multi-gear bikes which keeps them lighter, simpler, and easier to maintain. Harper’s top-of-the-line components still set you up for smooth sailing and effortless riding, 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.

United StatesSuper nice bike
The bike came nicely packaged, no damage. Which is great since the package traveled by ground from CA to FL. Very easy to assemble, just had to make few adjustment, the chain was too tight, and the rear hub needed to loosen a little bit. But that's all. It's lightweight. The ride: smooth and nimble! I highly recommend the Harper Coaster.
