The Mini125 is a design of portable bicycle. The current production features four models that have the same frame design but different wheels. The standard model weighs 5.9kg, folds into a 73x36X22cm package and has polyurethane wheels of diameter 125mm or 110mm. The gear assembly is typical of city bikes, while the transmission uses a minimoto chain and pinion. Mini125 is marketed under the MDEbikes brand and was released and presented at the 2003 Handmade Bicycle Show of Tokyo. The bike is designed and developed by Giuseppe and Paolo Ganio of Turin, Italy. (Giuseppe is also an entrepreneur at it:Mdebikes, Alpignano, Italy.)
The Mini125_100 has 100mm diameter wheels, the smallest in the world on a riding bicycle. Made of high-rebound polyurethane, they achieve low rolling friction despite the small diameter. Another model, Mini125_p, features pneumatic tires for riding in historic city districts. The Mini125 was originally designed with roller ski wheels, the only 100mm quality polyurethane wheels then available. Polyurethane kick scooters wheels became available during development. Since inline speed skates began using larger wheels, such as 100mm and 110mm, the Mini125 can use those.
