This is a Swedish scooter from 1959 that I didn't know of until now.
It's origin is a Swedish 50 cc scooter-moped from Husqvarna, penned by the Saab-designer Sixten Sason. It had 1 hp strong Husqvarna-engine and pedals according to Swedish law.
In an attempt to conquer the US market this Husqvarna Glider was developed. The front shield was extended with floor boards, a kick pedal and a foot brake replaced the pedals. Still a 50 cc but enlarged to produce 2,5 hp.
At least a 100 of them were built and they occasionally show up for sale or in forums in the USA.
To me it's much cooler than the Husqvarna Parilla!
