Thanks for the reply.
Thank you for highlighting the importnance of a quality transmission/gear reduction.
How big a hassle is it to upgrade the transmission/gear reduction later? I would dearly love to get a kit like this http://www.bicycle-engines.com/49cc-...ngine-Kit.html
, but the price difference is quite a bit, given exchange rate and that shipping from the USA costs so much more.
I guess it is all down to how much I value my time, eh? A ****ty kit will lead to hours of trouble in the future.
I guess I'd like someone to reccomend Chinese 4stroke kit.
If that isn't possible, I'll save my money for something better.
