Ah, you've opened a big and contentious one here.
The answer is an absolute yes. Everyone should be able to ride no matter how bike-abled they are. I think that the right to bike is up there with the right to walk. Bikes should not be reserved for any self-ordained elite. This world owes people a fairly fast efficient method of travel, no matter their circumstances. Those of us that have invested heavily in bicycling theories and fine bicycles must accept that there are bicyclists of all abilities out there.
Having said that, I also support universal education about bicycling.
