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 2018 through 2021 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.

Pivot – Les

About the Pivot LES
The Pivot LES came on the scene in 2012. Prior to this Pivot only built full suspension bikes.
The LES is a carbon frame and has sliding rear dropouts and is one of the best hardtail frames on the market.
As a quick overview, the Les can be built to have 27.5″ wheels, 29″ wheels, fat bike wheels, single speed, geared options, and even has a Pivot Les super light race version.
Now lets talk about the single speed options.
To get a Les as a Single Speed you need the Pivot Les version of the frame, not the Les 27.5 or Les Fat. Once you have this frame the rear dropouts need to be changed with a kit from Pivot and you are good to go.
Les Details and Specs
- Frame: LES Singlespeed
- Front Fork: VFox Factory Stepcast 32, remote lockout, 100mm
- Wheels: 29″
- Wheel Spacing: 148 Boost Spacing
- Brakes: Disc (160mm front and back)
- Dropper Post: Compatible
- Frame Sizes: XS, S, M, L, XL
- Colorway: 2020 & 2021 Factory Blue
- MSRP: Frame only $2,399. Pro Build $5,099
- Where to buy: Your Local Pivot Dealer or competitive cyclist

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.
Karate Monkey Details and Specs
- Frame: 4130 CroMoly Steel ‘Natch tubing
- Front Fork: Rigid
- Wheels: Salsa Hubs with Maxxis Ardent 29 x 2.4″ Tires
- Wheel Spacing: 145mm (can fit 142 or 148, or 135 with spacers)
- Brakes: Disc, Hayes Mx Comp
- Dropper Post: No but does have holes for internal routing
- Frame Sizes: XS, S, M, L, XL
- MSRP: $1,200

Canyon Single Speeds
Unfortunately Canyon does not make any Single Speeds
I could not find any single speed info so I sent an email to their customer service. Here is the reply:
Hi Steven,
Thank you for your email and interest in Canyon!
For our mountain bikes, we do not recommend them being used as single-speed bikes. Without the design and engineering to support this function, we are not able to make this recommendation. We do apologize for any inconvenience.
All the best,
So there you have it, if you hear of them making a single speed post in the comments and I will get the info added
