Allow me to disagree... I have bought a 'Winner Sport', and it came with a 2 speed transmission. It looks like the 'Speedy Tiger' has only one speed, though. And from what I've seen on the net, the 'Winner Pro' is also equipped with a 2 speed transmission, as opposed to the 'Commando', with one speed transmission.

But it looks like the two speed transmission has some problems (see my other post).
