I don't think redesigning the bicycle will make for change. Provision of infrastructure, especially safe cycling space is critical. I have just cycled about 20km to work mostly through a rural, hilly area. The side of the road available for cycling was rough, narrow and sometimes gravelly, which made it dangerous, especially as it was fairly busy. We need smooth tarmac and a metre width of dedicated space. In the long run encouragement of sysling will reduce the cost of road maintenance and be to everyone's advantage.
