Here is a new product from Blue Sky Designs is a speeder velomobile kit. The price of this kit is 850 dollars with 200 dollars shipping. It is designed to fit over a standard recumbent trike. This could be a great shell for a velomobile and you can still choose the trike of your choice. Another benefit is the fact that this velomobile looks as if the shell is easily removable in case you wanted to ride without the shell on.
