Flip flop between fixed and single speed
Harper is our 2-in-1 dream ride. Stick to single speed, or switch to a fixie with a flip of the back wheel for a guaranteed workout.
Easy riding and maintenance
As simple as it gets. Single speed bikes have fewer components than multi-gear bikes, which makes them lighter, less complicated, and easier to care for. 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 Stateseasy to put together, buy a size down tho
it was easy to put together. took one week to arrive. no scratches. i read a lot of reviews here about the sizing issues and i chose to size down. i'm 5'2 and bought a 43cm. my standover is very close to the bar. it fits like my old 47cm mercier.. i would size down for sure for the perfect fit. it feels pretty light. remember to be careful of the box if you need to return it.. worth the 200

United StatesHarper Single Speed (xs)
The Harper is a good value for the low cost. i am glad I ignored the height chart and relied on the stand over height. I am 5’5” and there is no way someone who is 4’ 9” could straddle the top rail. The unpadded seat with no springs and the handlebar grips were extremely uncomfortable on longer rides. Upgraded both and had to add a kick stand.

Got this as a just cause I love you surprise gift for my partner in celebration of black history month and they loved it especially because the blue is their favorite color! They said the bike rides like a dream too and I assembled it in an hour
