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.

Richard H.
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.

United StatesBeautiful easy to assemble blue bike
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

United StatesGreat purchase!!!!
Shipping was very quick! The assembly is straightforward and took me under one hour to complete with no extra tools necessary. The bike rides very smoothly. I love this bike & so happy with my purchase! However, to pump up the tires you will need a converter for the presta valve, which is not included. I found one at a local bike shop for $1.99.

United Statesbetter than expected
Only used the bike for a couple of days but overall been a good experience. For the price I wasn’t sure what to expect when ordering but once it got here and I put it together I was pleased with the quality. It’s not the best nor the worst but I can say I was pleased with my purchase and would recommend if you’re looking for an affordable single speed bike. I normally ride a mountain bike so it takes a bit of getting used to the different style but otherwise I like it and hope it lasts me for quite a while.
