The Blue Sky Speeder is a nice looking velomobile shell that will add aerodynamics to your trike and get you out of the cold rain. The Speeder is priced at just $850 plus $200 shipping and I assume that is to the lower 48.
The Blue Sky site states “These are generic parts and can be adapted or modified to fit a wide variety of HP vehicles; however we cannot guarantee they will fit or be suitable for all applications. The instructions should be used as guidelines in adapting these parts to your particular machine. We have used a Terra Trike as a sample application. If your HPV is similar dimensionally, it should fit with little difficulty.”
