Ideas for getting out in nature and come along hiking for people who need to use a wheelchair
Research sketches by Frits Ahlefeldt, part of the Hiking.org Wheel-hiking research project
Hiking can sprout innovation in many ways, one of them is to find new ways to keep getting out in the landscapes and nature using innovative kinds of wheelchairs.
There are many types of terrain going wheel chairs, both electrical and non-electrical and here are research drawings of a few of those wheelchair types that could be interesting to look at when heading out on hiking trails:

Innovation of wheel-hiking vehicles
Hiking is in many ways sparking innovation, the above concepts for trail going wheelchairs is just one example, and there are many back-country trails where these wheelchairs would work fine, also this is a new way of using wheels out on the trails. On some sensitive soils it will not be a good idea, but on many park, forest and low-land trails, and on coastal trails these new wheel-based hiking vehicles can make hiking experiences much more accessible to people who need some assistance to follow the trails.
