When the World held the international conference on slowing global-warming, scientists from MIT appeared. And they named a project over the capitol city where it was held. Hence:
The Copenhagen Wheel. For about $500.
There have been many prototypes for awhile now to make such a reality, and now it's a year, or less, from the market. And MIT doesn't mess around. So it's time any conscientious bicycle-mechanic start seeing what is likely to come down the road.
We can fight later about "is this a REAL bicycle?" or such. But as a friend of mine pointed out - this could popularize this form of transportation to people of all ages that simply have hills in their way. Transport & environmental protection. All wrapped into one - and many others.
