I am building a couple of CNC machines for my shop.
To gather information, I subscribe to a number of email lists and good vendors get mentioned on these lists. I ran into this place this evening and thought I'd share.
Check out: Electric Scooter Parts
From my viewpoint -- computer control of machinery, they have a wonderful range of motors, controllers, power transmission (chain and belt drive and pulleys/sprockets) for very reasonable prices.
From the viewpoint of someone doing robotics, the same applies. They don't carry any remote control transmitters or receivers but to build a robot, everything else is here.
From the viewpoint of my Mom who suffers from arthritis (as well as being 86) and is in a scooter full-time, this place is an awesome resource for spare parts and accessories.

Check out these Mag wheels:
Mmmm... Chrome and fins -- what's not to love:
The lens on the taillight is 3" in diameter. That will make a statement at the community center! Gotta get her an obnoxious backup beeper too.
They also do a lot of replacement parts for battery bicycles and scooters. Prices are great and these are supposed to be awesome people to deal with (according to the email list).
