Three Wheels are a common site in Minneapolis. This one and another were out around Lake Calhoun a couple days ago when I was doing errands. While most streets and trails are passable on two wheels a three wheeler is insurance that you won’t fall. How much is insurance worth to you? The Greenspeed Anura is a recumbent trike we may see more of as baby boomers find more time in their day to use bicycle transportation. As for now, if I was going to invest in a long term three wheel bicycle it would be a Dutch cargo. One day we will give up the second car and stash the bike messenger bag for smaller loads. That will be the time when daily activity for most of our generation is slowing down but we will be more physical than ever.
