The manual wheelchair is propelled by the user by pushing on the rim. The wheelchair also has handles on the back so that it can be pushed by another person.

A typical manual wheelchair weighs between 16kg to 22kg. It is foldable and often comes with detachable parts such as wheels and arm rests for portability.

The powered wheelchair is an option for persons who have difficulty using their arms or do not have the upper body strength to self-propel a manual wheelchair.

Powered wheelchairs run on electricity and are propelled by a motor and rechargeable battery. They are usually controlled by a hand-operated joystick. They can typically travel between 3 to 6 miles per hour (5 to 10km/h) and a distance of 10 to 15 miles (16 to 24 km) per charge.

Mobility scooters run on electricity and are controlled by a steering tiller. They can be front-wheel drive or rear-wheel drive.

Users need to be able to sit upright and operate the controls safely.

These are powered wheelchairs that are capable of mounting kerbs and going up and down stairs. The wheelchair climbs stairs by means of two endless belt tracks that are lowered from under the chair and adjusted to the angle of the stairs, allowing the user to ascend and descend stairs while remaining in the wheelchair.

Sports wheelchairs are designed to have higher speeds and ease of manoeuvre. The wheels are angled (i.e. cambered wheels) for added stability. The frame is made of material that is sturdy enough to withstand rough handling during sports but yet lightweight enough for agility.

All-terrain wheelchairs provide the user with opportunities for outdoor ventures further than what most other wheelchairs would allow. Designed with different functional wheels and different powered capabilities, they give the user the choice to go to places with different conditions and terrains, for example, to travel over grass, gravel, sand, snow and other rough surfaces.

A handcycle allows riders to propel using their arms instead of their feet. It is mostly in the form of a tricycle, with two coasting rear wheels and one steering front wheel.

Handcycling is also a form of exercise to improve cardiovascular health and increase upper-body strength as well as a recreational activity to ride with family and friends.

In the United States and the United Kingdom, vehicles can be converted for wheelchair users to drive from their wheelchairs.

Conversions could include the installation of remote operated tailgate and ramp for wheelchair access, hand controls, wheelchair docking devices, and removable and interchangeable front seats so that a wheelchair user could drive from a wheelchair or travel in a wheelchair in the passenger position.

In Singapore, approval from the Land Transport Authority is required for certain vehicle modifications so as to ensure the safety of all road users.

This wheelchair accessible three-wheeled motorcycle has a drop-down ramp at the rear of the vehicle that can be controlled remotely. It allows the rider to pull his or her wheelchair into position and secure it with a push-button docking system, and drive directly from the wheelchair. The controls can all be operated by hand.

The Kenguru is an electric car for one-person use. The driver presses a remote control to open the pop-up back door. A short ramp descends, and the wheelchair user can roll into the driver’s area. The driver controls the vehicle via motorcycle-style handlebars.

The Kenguru can travel a distance of 45 to 60 miles (70 to 95km) per charge and its speech can go up to 25 miles per hour (40 km/h).

It is expected to be commercially available in the United States in 2015.
