Yep, so you can easily get SupaSwift blades etc. to fit your machine.
If you need to replace wheels, the Honda 200mm ball bearing wheels [or copies] work just fine. The big wheels make the machine quite easy to push, as it's not heavy.
The Big Bob series has certainly been through a few different companies, in its long production run.
Vulcan, Jetfast Industries/SupaSwift, and Allpower Industries, that I know of.
