Hi, I love that you are building wheels for the love and craft of what you do, not enough skill or enough appreciation of it these days.
I have to be brutally honest though, I don't like the logo/graphics
Sorry.
I think beautifully crafted wheels deserve much better.
I would urge you to think hard about what you want the logo to convey before hitting to paintshop pro or whatever. Try sketching it first perhaps. Also have a look at other good, relevant logos. I think this is a great example of what you should be aiming for:

Things to consider IMHO:
1. Free typefaces are about a good as free bikes: you get the occasional gem, but most are pretty rubbish.
2. A representation of a wheel is really difficult to draw and reproduce. Do you need one? (McDonalds don't use a picture of a burger for their logo)
3. Try to come up with an 'idea' that you use to design the logo around.
Logo design is not easy at all, I know I do it for a living
If you like I'll see if I can put some ideas together one lunchtime?
