It's not really that big a deal engineering-wise, but the attention to detail is nice.

Here's the page detailling how the gearbox works.

PS. I need to get those batteries back from you.

Jawa doesn't know anything about it. So keep guessing. As for the batteries give Travis or myself a call when you are around for finals and we can meet you over at the HS.
