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.

United StatesCan take a hit
I got hit by a car while riding this bike and even though I broke my arm, the bike only has a little scratch. So the materials are strong and good. I ordered one size down and the bike was still a little tall (made it hard to dismount in an emergency like before getting hit by a car)

United StatesExcellent for the price.
I've been riding my Harper 5 miles a day for the last 2 weeks. For the price, it's an excellent bike. As mentioned by other reviewers the cranks will probably need to be replaced at some point. I see this as a good base bike that you can level up with accessories. In this price range you'd be hard pressed to get a better bike and it's sharp looking. Already had some compliments on the "cool rims."

United StatesNice and comfortable
Bike is a bit tall. I’m not sure if I can swap it out or try a smaller size. I love it.
