Explore the Possible.

Working together to grow the sport of adaptive mountain biking.

What We Do


Trails can be enjoyed by everyone, including people with disabilities. We show what’s possible.


We bring athletes and organizations together to create new and exciting adaptive experiences.


We help mountain biking clubs and trail organizations know what to do for inclusive trail sports.

Adaptive Trail Design Specs

Below is a list of non-negotiable features that will enable most adaptive mountain biking equipment to successfully access a trail.


These features are meant to be a starting point and should be considered the minimum standard. They may create difficulty for less experienced athletes and/or be challenging for athletes with varying physical abilities, so please consider exceeding these standards whenever possible.

Trail Width

  • Average: 48″ (1.2m)
  • Minimum: 40″ (1m)
  • Safety shoulder: 8″ (0.5m) minimum


  • Can be widely variable
  • Must be predictable
  • Majority: 95% compacted

Running Slope

  • 20% (11 degrees) or less
  • 8′ (2.5m) or more between rollers

Cross Slope

  • Straightaways: 8-14% (5-8 degrees) or less
  • Turns, berms, TTFs: 58% (30 degrees) or less
  • Safety shoulders: 33% (18.5 degrees) or less

Corner Radius

  • Straightaways: 20′ (6m) or more
  • Turns, berms, TTFs: 15′ (4.5m) or more
  • Exits lower than entries


  • Full width TTFs: 12″ or more
  • Partial width TTFs: 6″ or more


  • If unavoidable: 48″ (1.2m) or wider
  • Wider if not straight


  • Likely

FYI: Adaptive Trails vs. ADA Trails

One of our focus points at the Adaptive Trails Coalition is promoting the building and modification of trails to be suitable for disabled athletes riding adaptive equipment alongside non-disabled peers. We do not focus on ADA-compliant trails and this information should not be perceived as such. ADA compliance requires wide and level paths of travel with solid surfaces that are suitable for use by everyday wheelchairs. Adaptive trails provide much more access to the great outdoors, but necessitate the use of adaptive equipment.

aMTB Equipment

There are lots of adaptive mountain bikes (aMTBs) on the market. The following are currently the most popular and the most versatile options that are ridden by adaptive athletes around the world. If you’re looking for a new aMTB for yourself or for a program that you’re part of, start here.

ReActive Hammerhead

Full-suspension offroad handcycle designed for riding in the prone position. Puts body weight over the crank set for added power. Electric assist optional.
