    How does the power get to the rear wheel?

    Yeah, that part is obvious but what is not obvious is how it's driving the rear wheel.
    From the pics, the chain is centered away from the wheel axis.

    i believe it would have a sprocket on the spokes like the HT's.
    do you think this would be more relaiable compared to a standard HT?
    this price cheaper aswell, however you would need to buy parts like a HT throttle assembly etc.

    Yes, much better pics.

    It's using a CVT and then chain to a fiber gasket bolt-on type sprocket. Looks like a Mitsubishi clone 2 stroke.
    It says it comes with a "hand brake type accelerator cable", so you might be covered there if it's long enough to reach the bars. You'd probably want a kill switch and wire on the handlebars, these engines usually have a switch right on the engine. The ad doesn't really show if you get the wheel sprocket. though.

    Overall, it's an interesting set-up, the first of it's kind I've seen. Whether it would be more reliable than an HT, hard to say but my guess would be yes it would. These Chinese Mitsu clones are usually much better than HTs. They are very loud though. Part of the reliability question would be how the CVT holds up though lots of guys here use that type CVT with decent results. The sell for around $60US. One could also probably substitute out the rear sprocket attachment to a BMX free wheel type.

    The thing that jumps out the most though is the price. If I'm reading the ad correctly, right now it can be bought for $105AUS shipped. It I could get one for $100US shipped I'd buy one as soon as I submit this reply, lol. The stainless cradle alone would cost me that to have fabbed. How could you go wrong?
    Thanks for sharing and let me know if you pull the trigger.

    there is also this type on offer, its slightly different, would need to make a rear mount for it.
    i already have a HT, i wanted to get something like this for my brother or cousin.
    it gets a little boring in Adelaide (Australia) with not many people to ride with lol.

    Interesting, go for it then. BTW, got a link to the other set-up you mentioned?

    Yeah....RC in name only. These are Mitsu clones and pretty common really, I had one a couple of years ago and it was decent for the money. Quite a few guys here have gone that way.

    It actually appears to be a belt reduction, and not a CVT, HV. Also, there has to be a gearbox between the engine and the drive pulley. The drive sprocket rotation would be backwards otherwise. (And, the output sprocket would be spinning way too fast)

    Good eye there, Lou. You think there's room in there for a tranny too huh?

    so the motor wouldnt be ideal for a bike?
    the seller told me this when i asked how fast it would go on a bike
    "The fellar with the bike pics got his and his sons bike/motor up to 50 Klm"

    There has to be a gearbox that reverses rotation between the engine and the drive pulley, else the bike would be going backwards! I suspect one of the 3/4/5:1 pocket bike gearboxes. (similar to the pic below) They don't take up much space, and the pulley could be mounted directly on the output shaft.
