If you don't want to remove a wheel to repair a puncture then just use a linear inner tube.
But it can be harder to find what caused of it if you cannot remove the tyre to really check it.
So it's probably a bit 50-50, the ease of fixing puncture vs the risk of second one.

YMMV ....... :D

I carry a linear tube as a spare for the rear - the “fairied” inner gets tied around the chain stays until I get home.

On an open trike it’s trivial for the fronts, since the tyre can just come off. On most Celia I think the same is the case (though it might be more fiddly.

Would some expert tell a "virgin" the difference? Isn't a velomobile a trike with a fairing?

I'm no expert, but IMHO a velomobile usually has a unibody construction (mostly, or all, in fibre reinforced plastic), as opposed to a trike chassis which usually can function without the fairing(s). Cross section of a Sinner Mango shows the general idea (only the central spine being welded Al section), although the latest designs use mostly carbon fibre for all but the wheels, tyres, axles and drivetrain.

A velo is a complete shell - it might be on a traditional framed tried (like the Borealis) or it might be a monocoque (Like the Alleweder or the quest/mango series).

For obvious reasons the monocoque is favoured by those building dedicated velomibiles, but the 'shell on a trike' designs do have merits as well.


If it's a bike (rather than a trike) in a shell than I'd call it a streamliner - properly fast, but not really suitable for road use.

Ah. Construction design rather than overall use then. Thought it was something "bigger" eg 4 wheels.

Both three and four wheel velo mobiles exist.
4 requires more sophisticated suspension.

Here is an other view of the Quest velomobile: http://en.velomobiel.nl/quest

There is currently only one 4-wheel velomobile available: The Quattrovelo from Velomobiel.nl

At the moment, a motorized four wheled "bike" falls outside the scope of the E-bike law.
That only covers "bikes" with two or three wheels.
So it will need tax,insurance and mot to go on the road no matter the motor size.

Luck ............. :D

The Quattrovelo uses a double freewheel design rather than a differential.

Dual freewheel is also a better solution for a pedal cycle IMHO
