Re: greetings from ca.
I welcomed you in a private message, Scratchbuilder but I'll say it again. Welcome.
Take a look at the sub-forum headings. Almost every topic about motorized bicycles is covered. There are a couple, 'The Tavern' and 'General Discussion' that covers about everything else.
If you have questions that you haven't found answers for you can start a new thread in the appropriate section. Our search feature can also provide you with lots of information. Just type in key word/s and you'll have plenty to read.
Keep us informed on your progress and as others have said, post pictures. Everyone likes to see what the other guy or gal is building. Good luck, have fun and ride safe.
