FWD engine/box and chain drive

Ok, so I was thinking of power unit for a rev trike - something like the 1.0 ecoboost but keep its gearbox.

Does "locking" one driveshaft output and fixing a chain and sprocket to the other (obvs it will need assistance to hold sprocket in place) sound feasable ?

Cheers

Agreed. I wouldn't expect he diff to last long and it would likely be absorbing a fair bit of power whilst it was working.

You could lock the diff completely and run a chain final drive close to 1:1 I suppose.

Not sure of the practicalities on a fwd diff - but could you not weld up the diff?

I've not designed or built a trike myself so a quick question...

Do you intend your trike to be mid engine RWD?

If so is it not easier to use a motorbike engine that's surely already designed for this type of setup?

Another question, does a trike have to have a reverse gear?
