Although I enjoy the Harrison and my Ruttman Pac mule, The old school mini I would like to replicate from my fondest childhood memories would be the front peg Bonanza BC1200, with the mighty Briggs 5HP for power we had many adventures together................Tom.
I love them all even the ugly MTD Columbia and the Ropers with top mount tanks, I have had many of both and still own an MTD and two Ropers but only because I can't stop buying minibikes. My favorite in my stable is one of the most unusual badged Trailblazers I've ever seen. A guy who owed a grain handing company was a Shriner and wanted some minibikes for his Troupe, he got ahold of General Appliance and found that the minimum order was 50 or more bikes. He only needed a dozen or so but ordered 50, some suspended some not. He sold the surplus minibikes at his grain handling company and they sold well from the story I heard. Some members here doubted the story told to me but then a guy from Clay Center Kansas came on here and confirmed it, he said he rode some of the minibikes in the family's big yard when he was a kid in the late 60s early 70s he wasn't sure exactly. Anyway here are some pics of it.
