Single Speed Mountain Bikes

Single Speed Mountain Bikes are fantastic to ride and own. Not every bicycle manufacturer makes them so I created this post to view them all in one place. I have tried to include all the 2019 & 2018 SS Mountain Bikes I could find. Each single speed bike lists the manufacturer, model, price, specs, and a quick overview along with links to other pages with more information.

This post came together because I am currently looking for a Single Speed mountain bike and I had a bunch of research. So putting my notes into this post seemed like a good idea.

If I have overlooked any bikes please let me know in the comments and I will get them added to the post.

Surly - Karate Monkey

About the Karate Monkey

Surly is a well know bike manufacturer and the Karate Monkey was instrumental in showing the world what 29ners could be.

To me, this is a very solid if, not the best choice for a high quality less expensive single speed.   It is incredibly well built has a long well-known history.

In 2017 after about 15 years of no changes, Surly made a few design updates, including holes to route the cabling for a dropper post and other nice modernizations.

The Karate Monkey is available as a single speed or built up with gears.

This frame also runs what Surly calls “Gnot Boost” which means it can run 135mm, 142, or 148mm (boost) hub spacing. This is key if you already own wheelsets that are 142mm or 148mm.

Currently right now (August 2018) we are waiting for the 2019 Surly bike details.  Once they have been announced I will update the post.

Interested in Cycling, Running, Web Design, and reading reviews of products I will never buy. If you see me looking at my phone I am probably playing Pokemon Go.

To the person who stole my Fitbit, let’s keep it up. We had a great July, now is not the time to lose momentum.
