Welcome to Bicycle Colorado’s adaptive riding page! We’re excited to share resources to help you, your family or a friend get riding, or to help you be a more informed and courteous cycling peer. We hope you’ll reach out with any feedback, suggestions or questions by emailing us at info@bicyclecolorado.org.


On this page, we provide links to resources and opportunities for riders with disabilities and injuries, as well as older adults who want to learn about modifying how they ride. This page also serves as a resource for people who want to support other cyclists with different riding experiences.


A special thank you to our partners at Quality Bicycle Products (QBP) for their sponsorship to support the development of this resource and other equity initiatives at Bicycle Colorado.

Types and retailers of adaptive equipment

People with physical, learning, psychiatric, neurological and/or sensory disabilities or injuries, and/or whose bodies are changing with age, sometimes modify the traditional two-wheeled, leg-powered bicycling experience to meet their needs. Riders might modify two-wheeled upright bikes, ride adaptive devices like trikes or tandem bikes or ride with a partner who can help power or steer. They also might adapt their riding style so they can continue riding safely.

Adaptive bikes and modifications come in a huge variety. We couldn’t list every single adaptive bike here, since each individual has unique needs. However, there are general kinds and styles of equipment that are most common. This section goes over a few different kinds.

Four people smile toward the camera. Two of them are sitting in wheelchair bikes, being piloted by two people standing behind them.

Overall, bikes can be adapted with a variety of features that can be combined to provide the best use for any rider:

  • They can have two, three or four wheels. Three-wheeled devices are called trikes.
  • They can be recumbent, upright or prone.
  • They can be hand-powered, foot-powered, and/or electric powered. Many devices have e-assist options.
  • There are bikes for single riders, as well as tandem bikes and wheelchair bikes for people who want to experience a bike ride with a pilot pedaling from the back.
  • There are versions of adaptive bikes for general use or competition, and for road or pavement as well as off-road riding.

Additional modifications for bikes and trikes can include changes to the seating or braking, modified handlebars, modified pedals and much more. Work with a local bike fitter to talk about what would be best for you. The Organizations and Programs section also lists partners that adaptive riders may contact to ask for advice.

Types of adaptive devices and modifications


Recumbent bikes and trikes allow the rider’s back, neck and hips to be fully supported and resting against a full seat back and headrest.

Recumbent trikes, in particular, come in two standard forms: delta and tadpole. Both styles have full seats for riders who want more back support.

Delta trikes have one wheel in front and two wheels in the back.

Tadpole trikes have two wheels in the front and one wheel in the back.

Supine trikes are similar to recumbents, but the rider is lying almost flat on their back.

Upright bikes and trikes have seats similar to traditional two-wheeled bikes, without back support. The rider sits upright and unsupported.


Prone trikes allow the rider to lean forward and have their torsos supported from the front.

For those with leg function, many adaptive cycles can be powered by feet and legs, like traditional two-wheeled bikes.


Handcycles are pedaled by a person’s hands and arms.

Electric motor

Many bikes, trikes and other adaptive devices come with an electric motor, and can be e-assist or fully electric powered. These can be useful for people with muscle weakness or paralysis. Many older adults also find eBikes allow them to continue enjoying biking as their bodies change with age.

Motorized trike attachment

People who use wheelchairs can use a trike attachment that connects to the front of their chair and lifts up the front casters, allowing the wheelchair to be turned into a sort of electric motorized trike.

Single rider

Many adaptive devices are for one rider to power and steer on their own. They may ride with other people or receive some other assistance, but their device itself is separate.


There are versions of tandem bikes that look like traditional upright two-wheeled bikes with one person in front and another behind. There are also trike versions with recumbent seats, with electric power, hand-powered and more. There are even tandem bikes where one seat is traditional and upright, and the other is recumbent!

Wheelchair bike

Wheelchair bikes provide an opportunity for people who ride wheelchairs to comfortably enjoy a bike ride with the support of a riding partner. An upright bike with one wheel in the back is attached at the front to a wheelchair seat with two wheels, or to a wheelchair ramp. One rider pedals and steers from an upright position behind the person who uses a wheelchair.

How to find accessible trails

  • COTREX, the Colorado Trail Explorer, is a free web and mobile application that allows you to discover public trails across Colorado. Select the “Wheelchair Friendly” option to filter for accessible trails. Additionally, note a trail’s “surface type”, which can be seen at the bottom of each trail page; to see if it is a surface suitable for you and your device.
  • The City of Boulder’s Open Space and Mountain Parks Accessible Trails and Sites PDF booklet offers information on where and how to find accessible trails in the area and what you can enjoy on those trails. This document is a PDF.

Considerations for other riders and decision-makers

Not an adaptive bike rider, but want to be a more conscientious and courteous bicyclist or decision-maker?  Here’s what some of our friends in the disability community have shared:

People ride on a dirt trail. In the foreground is a person riding a recumbent trike. Further in the background there are more people riding recumbent trikes.

How to share paths and trails

  • Treat adaptive or disabled riders as equals who have the same right to use the trail as you.
  • Remember that other power-driven mobility devices can go places a regular bike is not allowed. These devices include power chairs and adaptive electric-assist devices.
  • Offer assistance if you feel a rider is struggling but don’t assume that they need it. Remember that some adaptive riders may take more time, particularly going up hills.
  • Be aware of others who may have a lower profile on their adaptive device.
  • Give plenty of warning when passing.

What decision-makers should consider

  • Ensure sidewalks are accessible by prohibiting obstructions, making them wide enough and constructing curb ramps at intersections and crossings.
  • Step up education for trail users, bike path users and motorists about navigating safely near adaptive and disabled riders.
  • Ensure large turn radii on trails so that three-wheeled and/or wider devices can make the turns.
  • Consider slope and cross-slope: make sure trails aren’t too steep or have too much of a side-slope that could cause bikes to go off trails.
  • Clearly mark directional trails.
  • Mark trails, roadways and bike facilities that are not accessible.
  • Ensure that trails are wide enough at gates for larger adaptive devices to make it through.
  • Communicate trail, sidewalk or road construction and closures ahead of time.
  • Ensure alternate routes for closures have suitable hard surfaces, with no dirt or mud.

For the bike industry

  • Make adaptive cycles and equipment more visible and available at shops, expos and events.
  • Learn about various adaptations that your customers or event participants may need or use.
  • Get trained on how to help people find correct equipment for their needs.
  • Advertise to agencies who work with or support non-typical riders to encourage their members or clients to attend events.
  • Make ride entry welcoming and inclusive.
  • At events, provide accommodations like specific fields and groups.
  • Gather and provide information about adaptive cycles and organizations from adaptive programs and riders.
