Versions:
* 4 wheels using mountain bike 19in rims and 2.75/19 motorcycle tires
* 100kg weight
* 2 occupants
* Twin 3-5kW Axial Flux BLDC chain-driven motors (no gearbox needed)
* 1.1 x 1.5 x 3.4 metre dimensions with an "airbox" down the centre
* Only a 1.1 m^2 front surface area (due to the "air tunnel")
* 0-60mph in under four seconds (Sur-Ron "3" kW Motors can be pushed to 13kW for short durations, and there's two of them)
* over 200mpg at 55mph due to low weight, low rolling resistance, reduced surface area and low drag coefficient.


=Design Concept=
* [[UELVE MBC/v0.0]] (concept, initial CAD, scale model)
* Use downhill mountain-bike parts that have been proven to be light, strong and effective up to a 50kg weight with an 80kg load, thanks to the Sur-Ron Electric Bike.
* [[UELVE MBC/v0.1]] (build underway)
* Use twin Sur-Ron direct-drive 3-5kW Axial Flux electric motors
* Use twin ASI BAC4000 BLDC Controllers (or VESC Vedder BLDC Controllers http://vedder.se/2015/01/vesc-open-source-esc/)
* Outer skin using the GABoats technique (Geodesic Aerolite Boats) - http://gaboats.com
* Inner frame using 3D-printed fibre-reinforced "nodes" connecting continuous-fibre-reinforced pipes on a [[Fibre_Reinforced_Pipe_3D_Printer]] or getting carbon-fibre, hemp-reinforced tubes (or even Bamboo), based on the Divergent 3D "Blade" car manufacturing concept https://www.youtube.com/watch?v=vPv7PwS50OE
