Frankly, that does not sound like 2 functional limbs. Now consider that it would be easier for your charity team to drive you around if there was less traffic. Meaning the more healthy people cycle, the less traffic there is (assuming there's bike infrastructure, which is much cheaper than car infrastructure) the better you can get around. Alternatives to car driving even helps people who are actually dependent on the car.
I was going to type out a reply, but conditional_soup already said everything worth saying.
