Best Mullet Mountain Bikes in 2023: Mixed-Wheel Bikes

By Sam Millers   /  Last updated - December 29, 2022   /  Electric Bikes, Mountain Bikes, Mullet MTB, Reviews

mullet mountain bike explained

A mullet mountain bike is one with mixed wheel sizes. Most often this is a 27.5″ wheel on the back and a 29″ in the front, however, this can also be a mix with 26″. Companies who sell and riders who use mulleted mountain bikes claim that they provide the advantages of each wheel size.

Due to their popularity, many big-name brands now carry a mullet model. This includes companies like Specialized, Santa Cruz Bicycles, and Orange Mountain Bikes.

What are the benefits of a mullet MTB?

“The best of both worlds” is a common response to the question posed above. In practice, there are four distinct benefits. That being said, some riders may not consider these things beneficial to their particular riding style.

  • A bigger 29″ wheel controls more smoothly in very rocky terrain. The larger the wheel, the more easily it rolls over big hits and hangs up less so that you can control the bike better.
  • For riders who want more clearance with a smaller 27.5″ in the rear because their 29″ wheel kicks up over steep drops.
  • A smaller 27.5″ wheel in the rear allows more movement and thus improves cornering giving riders the ability to take corners at higher speeds
  • A larger wheel in the front compared to the rear will speed up your ride by creating a slacker geometry, improving stability, and reducing rolling resistance

A brief history of mullet bikes

A recent increase in the popularity of these bikes would make it seem like they are a new phenomenon. However, this increase is mostly due to their inclusion in professional spheres including EWS and downhill races because of recent changes to UCI regulations.

Mullet bikes have actually been around for over 15 years, as seen in Specialized’s BigHit in 2004 which mixed 24″ and 26″ wheels. Here are some of the reasons why they were invented.

29er PROS

  • Smoother roll over obstacles and rocks
  • Larger contact path due to larger wheel (Unless the rear tire is drastically wider)
  • Higher axle
  • More stability on higher speeds

27.5er PROS

  • Faster acceleration
  • Better cornering
  • Lower center gravity
  • Slacker geometry
  • Better clearance
