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
Jason S. from the UK recently bought on eBay a chrome Roller Shuttle, the UK branding of the Minson Skate Bike. While I have seen Roller Shuttles before, like Brent’s Brand New Unridden Roller Shuttle, I have never seen a chrome skate bike anywhere. Jason restores old Raleigh BMX Burner Cycles so he has the experience to do a wonderful restoration on the chrome skate bike.
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.
