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.
A homebuilt lightweight aluminum frame with a canvas hood. www.fabbike.cc
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.
A concept for the Makerbike2, with a solar roof panel.
This one was seen at the 2015 Hong Kong Makerfaire
The Vélo M² open platform cargo bike aka N55 with stackable watertight 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 ?
This looks more feasible: IKEA's SLADDA trailer.
