I am interested in this as well, as they seem to be very gray at best. Here is a copy of an e-mail that I just sent to the IL Secretary of State. I'll let you know what (if ANYTHING) I hear back from them.

Here's a copy of my e-mail to them:

Due to the incredible gas prices lately, I have been looking into alternate transportation to work. My question pertains to the requirements for a power-assisted bicycle. I have searched high and low and have not yet found ANY specific Illinois guidelines for them. I am wanting to buy one of these but want to make sure I'm in compliance with the law before doing so. I think it was the $95 cost to fill my van that finally made me start thinking about alternate transportation. By riding my power-assisted bicycle to work each day, I would save $10 a day, get some exercise, and use less foreign-sourced fuel. Please let me know how Illinois addresses power-assisted bicycles.

Thanks much,

Warner
