I'm considering building one of these for use on a rural property:

I've considered a motorbike would be easier. But I really like how you just stand on this and go, and step off again.

I'm thinking how to go about building it, weighing up what would be the cheapest cost of building/running and ease of maintaining it.

So far I've considered:

a. Making it electric using a golf cart motor, controller, and batteries

b. Just building it as pictured - with a horizontal-shaft Briggs & Straton engine (preferably with an electric start).

However there is also a third option...

c. Petrol engine again, but adding an LPG modification:

I don't not know yet, what engine the guy selling the plans recommends, and therefore do not yet know if there is a LPG kit to fit that specific engine.

Q1: I'm assuming B&S make a horizontal shaft engine with an electric start. Does anyone know if there is an LPG modification for such engines? i.e. Is there a common carby part number I could give someone that sells the LPG kits, to check it would fit? (Or are the LPG kits available in Australia?)

Q2: I'd also appreciate any thoughts/input from others, on what you think would be the most reliable, cheaper to build, and easiest to maintain over the long term. (i.e. Electric, plain petrol engine, or petrol engine modified to run on LPG.)

Thanks for reading.
