An addition with a large front wheel with a broad tire can be screwed onto a manual wheelchair in the same place where the small castors usually sit. All tires have a deep tread. The user tried different front wheels that are mounted in various ways: the current solution takes 5 minutes to switch (when not sitting in the wheelchair).
The user loves the outdoors. Since it is difficult to move around with a manual wheelchair on uneven terrain, she developed this solution. She tested different variations, see pictures.
Users should be aware that although the design works well, it overturns a little more easily than usual. The adaptation should be done at the user’s own risk.
