Oddscoot
From scoot.net
Oddscoots are scooters that were not as successful and/or not produced in as great numbers as Vespas and Lambrettas were. Many differ greatly in appearance to more common scooters. They are typically more rare and have a niche following.
Examples of "oddscoots" are the Heinkel Tourist, BSA Sunbeam, Rumi Formichino, Zundapp Bella, Fuji Rabbit, Maico Mobil, and Durkopp Dianna.
