Hello all! I've recently built a motorized bicycle with a bike from a yard sale. I ordered an 80cc engine kit from eBay and have it all assembled. I want to get this bike registered with a class B plate. I plan on having the engine tagged or stamped stating that it is a 48cc engine, that way I can go for the class B and not the class A. It has a headlight, turn signals (front and back), left and right mirrors, a bracket to hold a registration plate, and a tail light with a built-in brake light feature. After I get the engine stamped stating that it is a 48cc engine, will this form be the only thing I need to get it registered? Motor Driven Cycle (MDC) Affidavit - Affirmation of Ownership and/or Cubic Centimeters (CC) - State Form 55714 BTW I'm in Indiana and I do have a driver's license. I want the class B that way I don't have to get insurance and take a motorcycles endorsement test. Update: The BMV lady registered it for me and all went well! Took like 10 mins lol. But I just made up a number for the VIN. I did check online to make sure it wasn't taken by something else. Anyways. I ordered a small metal plate that lets you put your own numbers on it and the plate says VIN on it. Do I just tack weld it to the frame of the bike?
