How many toy wheels are included? I see it comes with 84 pieces of gears/other items, but I would like to know specifically about the wheels.

Thank you very much for your QA. Regarding the gear part, it is our problem that it is not clearly stated. This set contains 252pcs (84*3=252) plastic gears parts. All the accessories are three times as many as this picture(https://images-na.ssl-images-amazon.com/images/I/71bJQsqsg-L._SL1200_.jpg). For example, the wheel in the picture has 4, There will be 12 wheels in the package. If you have other issues, you can contact the seller directly. We will answer you quickly and wish you a happy life.

What if it is not working? I’ve connected the proper wires and put the batteries in but it’s still not working

Dear friend Thank you very much for your support of our products. There are 18 motors in our set. If they don't work, it may be a wiring problem. Please contact us (seller) and provide the complete wiring diagram to the seller. We will serve you. Solve all the problems, look forward to your reply, I wish you a happy life.

How do you attach the battery pack to the motors?

The set includes the wires that attach to the battery pack. Basically you can attach the wires by twisting them or using electrical tape. I just used the wires included and twisted them to attach. There is also instructions included.
