I'm not quite sure how ‘Envo’ from Canada came up with the idea of having the semi-enclosed vehicle built for the EU by ‘Geobike’ in Poland. But I'm pleased that things are moving forward at all on this topic.
If the price stays below 7500,- EUR, I could well imagine the bike for commuting from autumn to spring, for pensioners, or for families with child trailers.
I've heard that 3-wheeled vehicles are very difficult to balance. You'll have to go extremely slow when turning.
Depends on how wide it is and if the tires lean into the curve. With a Piaggio MP3 you can easily do 80 kph in a curve.
Not only on how wide, but how much weight is on the two-wheel axle.
