How To: Build a motorized bicycle


Dave made this informative video on how to attach a “Weed Eater” [string trimmer] motor to a bicycle. Used bicycles and string trimmers are easy to find and very cheap to buy. You could make this project for less than $100, maybe even less than $50. The information on modifying the clutch could be very useful in making robots too!
