So far the Begorett velomobile only looks like a design study.
At 40 kg weight and 1.08 m overall width I’d say it’s slightly overweight and at least 15 cm too wide to fit through obstacles if you leave the road.
That critique out-of-the-way, I really like the idea of four wheels and 26″ wheel size in a velomobile. I’ve got a fair share of bad roads as well as multiple train tracks and flap bridges on my daily commute and thus experimented with 24″ and 26″ front wheels on my Sprint again.
The Begorett velomobile is build (or better say might be build) on an aluminium tube space frame and the designers focus obviously lays heavily on cycling safety.
