Between BYD, Geely, and SAIC you would probably be backing a long term stayer in the market and a safe bet.

So government mandates are forcing this. I can understand not wanting millions of two strokes running in crowded cities. Imagine how much better the air would be with 4stroke bikes rather than 2 strokes (given the majority of road users are on bikes).

I don’t believe 2 strokes have been banned as such, but certainly not a popular option and seem to be non-existent in the new market due to tougher global emission standards. Same in Thailand.

More likely the move to Euro 5 standards that killed the 2 strokes globally. There are only a few manufacturers still offering as new Euro 5 compliant 2 strokes.

I love 2strokes ... but I can't understand how they would meet any standards ... you are literally burning oil in them. Maybe they have somehow dry sumped them and run a standard oil filled crankcase (though I can't quite understand how).

I can understand 2 stroke dirt bikes and chainsaws ... but to use them for normal transport is an awful idea. I should look at those motorbikes as thinking about it ... couldn't you run a hub motor if its electric ... so you would remove the chains, sprockets ... a lot of the maintenance upkeep required.

Agreed. The technology needed to make a 2 stroke clean goes against the whole principle of the simplicity of the original design. Needs fuel injection, catalytic converters/particulate filters, ECU’s etc etc.

I can see the technology benefits of electric vehicles starting to make more sense for you.

Much simpler and a lot less maintenance required.

Funny thing, when I lived in Bangkok up until 1991 the 2 stroke bikes came from factory quite clean and no visible smoke. The riders however believed that smoke = power and got service mechanics to turn up the oil injection until they smoked like chimneys. I bet it still happens.

Bit like some diesel owners today….

Detroit two stroke?
