Trikes and Bikes
The smallest mobile fablabs
London based Fab-BIKE has a two wheeled bike trailer with a micro-fablab on board: Ultimaker2Go, iModela, Emblaser1, sewing machine, Arduino and more.

I think a mobile miniFabLab should sport a real real lasercutter, like the Full Spectrum or the upcoming Glowforge (2017), which measures 965 x 527 mm.
FabLab Maastricht has a 50 years old bakers tricycle with a full blown fablab on board: a HPC3020 lasercutter plus several 3D printers.
Which reminds to a 1947 maker cart in the dutch book 'De Jongens van de Hobby Club'. This was playing with high tech then.
They cheat a bit, as they move this vintage thing in a transport-trailer to locations, where they fold out the tricycle.

How about fablab to make a mobile fablab ?
Philadephia made a modern mobile maker cart on a trike.
The Vélo M² open platform cargo bike aka N55 with stackable watertight boxes.
Here with a 3D-printer, laptop and beamer for the Vélo M² .
There is a complete instructable with .dxf files for the stackable boxes,
The mobile lab on the VéloM2. Nice, movable, but no lasercutter though.
FabLab Lissabon made a mock-up for their (unsuccesful) kickstarter project. Would that be stable to ride ?
With this makerspace on a bike with a folding workbench you leave the idea of a fablab - carrying at least a lasercutter - and come into the realm of the STEAM makerspace.
This looks more feasible: IKEA's SLADDA trailer.
