Hi there, to answer all of your questions:
1. The bicycle wheels are an issue with the actual model of the vehicle itself, something that I cannot fix, there are no model tools.
2. Wrench Jr mainly works with controller only, but is perfectly fine with a keyboard, if you are inside a vehicle. I wrote all of this inside the README text document.
3. The vehicles were originally in the dealership, but I had to remove them as it caused save game issues. If you uninstalled and reinstalled the mod, some cars would become locked forever and break your save. Again, this is something that was also in the README file.
