I don't know what series of motor you have. Not a lot of money.

Thx, I'll pull the motor apart to see what model.
I understand there is one model that req spec tools to get to gears (newer one), and this new model has rep gears
there is an old model that does not need spec tool..... and no gear avail....

Given the number of motors out there, it would be helpful to figure out how hard this might be, how expensive, and whether you need special tools, etc. I guess someone should be selling the gears, in the US?
The gears in my Mac are available and are composite, supposed to last longer. They say you need a gear puller, but the cover looks simple. I guess (pure guess) the Bafangs might start to need replacements at 2k and up. I'm hoping for 5k.
Hope it turns out to be simple and cheap. Be good to know if the 48 volts will be a problem, as well...

What George said.. also circlip pliers are needed.. and buy extra circlips.
Also try http://ebikessf.com/ they are pretty helpful as well.

OK, I've got circclip plyers CHECK!
I'm just waiting on my new 48v/1500 front wheel kit from the red-star country..... then sondor hub motor comes off, and we begin dissection.
