Looking to buy a new motor kit

I've previously ordered a 48cc 200watt motor kit from Rock Solid and unfortunately, I believe I got the Friday make. With the problems I've had and put aside (and waiting for warranty since they're on holidays too...), because I need a bike pretty much now, only problem is, it has to be 200watts and under or I require a license to run.

I've been looking around at the 50cc bikes as that's just about the lowest and the cheapest I can find is this:
Silver 50cc Bicycle Engine Kit

I really don't want to spend too much at this point in time as I don't exactly have work either... Anyways, it says 5-6 HP, how much does that equate to in watts in the end?

Well, that's when I read this reply from Noel regarding horse power to watt conversion:
Online Conversion - power- Horsepower to watts

I'm going to have to wait until January 10 before they can do any kind of warranty... Guess I'll be buying a new engine in the mean time.

May as well attach the replacement engine to a second bike for whoever might like to use it for a fun ride and whatnot.

Well, Raw Motor just got back to me that they don't ship to Australia...

Anyone know a company who does?

I'm thinking maybe all I need is a new engine since the only thing that broke really was the engine... It should come with a new magneto and clutch cover and all right? I could use some new ones too...
