First thing : it's a niche, in a niche , in a niche market.

Trikes are still a rarity.
Enclosed trikes / velomobiles are an even greater rarity.
Those riding them usually ride them to combine training and commuting (with some weather protection) and/or for ecological reasons, so they usually don't add an engine.

The legal issues are high - with every country and many US states having different regulations.
In the EU,anything over 25 kph makes it a moped, with all the legal haggle that goes with it.
Over 1m wide, and you're banned from cycling paths.
Over 45 kph you're into motorcycle territory ... more haggling.


I don't have say a Velomobile with a BionX engine though I could easily afford one.
My main issue is where to put it - let alone where to charge it.
I'm a city dweller, I simply don't have the space to put it except out on the street.


To find easier acceptance than a velomobile, it'd need to be more practical to use.
Easier to get into.
More and better accessible baggage space.

It wouldn't be unlike the Elf.
But I'd still not have the space to park it, except out on the street ...
