To make the drive go backwards you need to put the crown wheel on the other side of the pinion. On the old Scammel truck axle could do this my misteke and end up with 6 rev gears and one forward.

Not all drive trains will have enough room but its an easy way if you can

Funky idea, but no (not convinced how well it would suit the hundreds of motorway miles there and back  :o )
No, I'm looking for economy, performance, weather protection....

Stow away in GC's sidecar then...  ;D

Was going to suggest an Autobahn ready hovercraft as this would be warm being insulated from the ground, but not cheap.

A new take on the Messerschmidt or Heinkle 3 wheeler?  An Ecomobile from the Glens?

Would not need the axle for a Ecomobile.

What axle?....  ;)
A transaxle is just another name for a a combined gearbox and final drive (still relatively unusual when the Imp was designed)

Showing my ignorance then - thought it was a concatenation of Transmission and Axle, thus the transmission has output to a pair of drive shafts - the axle - rather than one which would lead to a diff etc.  If you were producing a single track - ie an Ecomobile, you would not need the two outputs, just one.

A twin track with drive to two wheels would need it.

Could be hoping for snow and a version of this

It does indeed have two outputs, but I only need one...
That bike you picture doesn't look very warm or motorway ready!

Ok I'll 'fess up(!)
I was/am looking idly into the technical difficulties of building a poor mans (normal mans more like!) ecomobile. The concept is good but their price completely ludicrous.
I was looking at an Imp engine/transmission purely because I have a spare one in the garage (doesn't everyone?!?) and being alloy construction it's relatively light for a car unit.

The idea would be to have an elongated "D" shaped loop of roll bar sized tube forming the horizontal part of the frame and encircling the rider passenger and engine, with the curved part of the "D" forming the nose of the vehicle with two elipses mounted vetrically just behind the rider and passenger seats, this would form the main frame and "safety cell" with conventional bike frame thickness tubing led off it to support everything else.
Looking at bike front forks/wheel/brakes controlled by drag links to a handlebar in the cockpit, rear suspension would be a swingarm mounted on a subframe off the rear of the main frame. Drive by chain from one side of the transaxle, the other side bolted off to prevent rotation and put all the drive to the chain side. Nose fairing from a butchered sidecar/bikefairing/roof box and remaining bodywork from alloy sheet. Windscreens from car glass (front panel in Spitfire/messerschmidt style!) and canopy a single curve sheet of perspex. Two seats in line with the rear passenger set a little higher than the driver.
Car seats, harnesess heater (oooh :)) and wiper etc, registered as a motorcycle (single track vehicle) The design of outrigger/stabiliser legs we're still thrashing out but we have identified at least one workable option.

Of course it's all just ideas, and I have no space/time to embark on such a project just now as I may be moving house imminently :O but it's an interesting planning exercise and I'm not ruling it out ;)

Moving house! Proper move or a flit, if I may be so bold?

Now we just need to transport back about 50 years....  According to my granddad - before he died - the hot cloche after WW2 was the bubble off a Spitfire, others were OK but the Spit had a nice shape.  some of the jets had OK ones too - Buccaneer comes to mind.  Now they would do you fine.

Sounds like a good idea and project, Could you not just steal the nose of a glider as the body?
