This is a 48cc Grubee Skyhawk bicycle engine, which I will install on my Schwinn Clairmont for a project in my senior year in high school. As you can see, some assembly required.

A while back, I had to leave an awesome fur meet early in order to pick this up from the FedEx station before it closed. So I REALLY hope this bike engine was worth it.

I will upload a photo of the finished product once it's installed!
