The 2x4-X

Yes, the 2x4-X is a bit heavy, but so are my off-road handcycles and wheelchairs with power assist add-ons.

I made this prototype primarily with free wood from the scrap bin at Home Depot. 

 

  • The 8" trike wheel is from Harbor Freight ($16).

  • Instead of metal collars, I am using cheap hose clamps for the 1/2" through axle.

  • The leg supports use 1x4s.

  • The seat and sideguards are 1/4" plywood.

  • Notice the "floating" seat design using a cut up foam block for "suspension". This method is used for lessening impact on martial arts floors for falls.

  • The backrest cushion is foam padding covered with black gorilla tape as a cover.

The 2x4-X is very cheap and easy to build. Perfect for learning about wheelchairs in terms of design and functionality.

A easy way to get started is by making a wood wheelchair model. The model in the photo above was made from popsicle sticks, a chop stick for the axle, and two old caster wheels.
