Recently Jon (UK) and I were discussing variations in the LeRun/Garel skatebikes. Jon is working on an article on those. My experience is with the Minson bikes. There were several changes in the Minson design, I believe for economic reasons (ie make it cheaper to manufacture).
The Minson Users Manual that came with my Minson shows the original Gen 1 version. Gen 1 bikes are the hardest to find.
Anthony from Australia found this 12″ junior skatebike on eBay in the UK. Notice they call it a Minson Roller Shuttle. Also it has the curved front support tube and even has the original box.
I searched on Minson Roller Shuttle and found this new eBay UK listing
I found the original owner’s manual for my Minson Skate Bike. I usually save owner’s manuals and while cleaning found it.
It is interesting that the manual refers to a 16″ wheel version (which is what I have) and a 12″ wheel version. I have never heard of the small wheel Minson. The LeRun used a 12″ wheel.
Brett from England acquired an unridden Minson skatebike, circa 1985. This is a first release version. In the UK it was called a Roller Shuttle. You can tell it is a first generation from the stripe on the seat, the brake mount and the secondary curved tube to the front truck.
