Those sure do look like "Lil" Indians don't they, Those wheels and sprocket are cool too. Are those pretty popular in NZ?, sure would be cool to have one of those next to my other bikes. Nice that you were reunited with your childhood mini and really cool of your friend to just stop by and drop it off, it's amazing he still had it.
They used to be reasonably common here. I bought my first one (pictured) sometime in the early 70,s. A little guy used to work with my Grandad and rode it to work, road legal. I got a Tecumseh kick start for it, $15.00 brand new and thought I had a real motorbike now, haha. I had a paper run that delivered in town to shops and hotels so would be in town every week day. The local Honda shop got a new QA50 and put it in the window. I used to drool over it every day. Plucked up the plums to go ask about buying it and paying it off with my paper run money, the guy said bring your Mum to sign that she will pay if you don't and it could be yours. Mum agreed on me selling the Tru test to put down 1/2 payment so got it sold and the QA50 was mine. My original Tru test went out of town about 12 miles or so and I didn't think about it for years til I thought about trying to see if it was still about. The guy I sold it to had since died but I went to High School with his younger sister and asked her if she remembered it, nah, so it went cold. The guy I got it from came in to work one day for some bolts and I asked what he was doing and when told a tru test, my ears pricked up and it turned out to be my old one. Has been through only 2 other people since I sold it. My friend was working at a sheetmetal shop at the time and had these sprockets laser cut, the original is still with the stuff he dropped off. Don't know where the original Tecumseh and kick start got to though ? The wheels are original to the bike and are 2 piece design. I also have a couple of QA50 projects in my shed.
