I have one too, the Sinner Mango+
with a 170W assist. It has an 11-speed hub gear in the rear which allows me the switch gears while standing stil, and a big metal U-ring which I use to chain it to an ebject wherever I park, not only against theft but also against strong winds which my blow the velomobile away.
My car ride to work is 38 km and takes between 25 (holiday season) and 60 minutes (normal traffic outside holiday season). With the Mango+ it always takes 65 minutes as I am not slowed down by traffic. The removable battery needs to be charged home and at work, so half my energy cost is even subsidized by my employer (but it isn't much anyway). With motor off, I cycle at ~32 km/h, with power I manage 38-42 km/h. The seat is comfortable and all 3 wheels are sprung, but it still is a bumpy ride due to the road quality, and the fact that you must keep your tires at 5-6 bar to reduce drag.
Without the wind cooling you, it can be hot in the summer, even with the foam top off. In the winter I wear a nitted cap, and a shawl around my neck, the rest stays warm inside. For me it keeps me in shape without loosing time in the gym, I exercise in the time I could have spent in traffic. At work I take a shower, which I would have taken at home if I went by car. I clock in after the shower, of course. For safety, I have daytime running lights (LED) and I chose a 2-tone (red & white) paintjob. When sharing the car roads you have to drive it very defensively as if nobody is seeing or expecting you, on bicycle paths the danger is a lot less. Part of my trip is on a bicycle path parellel to the slow-moving traffic, and it is very satisfying to go faster than the traffic jam.
