Given that I live in remarkably rainy Vancouver, I have a natural appreciation for a product like the GeoSpace FireFly. Here is a recumbent tricycle that has been outfitted with a weather-resistant dome, protecting the cyclist from rain, sleet and snow.
Tge Hase Klimax 2x recumbant bike saves you from the rain with an optional portable rain cover. It’s basically a recumbant bike (it’s really a trike, since there are three wheels), but it is power-assisted. There is an electric motor there to “assist users climbing hills or over logner stretches.” There are pedals too, if you want to make use of your own human power.
