Special wheel
In the German-speaking world, all types of bicycles are called special bicycles whose frame construction differs from the design of the diamond frame or women's bicycle with two wheels . Special bicycles are still bicycles whose intended purpose differs from the pure passenger transport or which have a different than the conventional crank drive with pedals . Bicycles for special sporting purposes, such as the pressroom called art bicycles , are also among the special wheels.
This differentiation from the standard bicycle affects the following types of bicycles, among others
| Bike type | Design feature |
| Recumbents with two or more wheels | Design, partly the drive |
| Oar wheels | Drive and design |
| Velomobile | Design |
| Tricycles | Design, partly the drive |
| Cycle rickshaws | Design, partly the drive |
| Cargo bikes | Design |
| Folding bikes | Design |
| Tandems | Design |
| Hand bikes | Design and drive |
| High bikes | Design |
| Pedelecs | Drive, partly the design |
| Pedersen bikes | Design |
| Standing bikes | Design |
| Tall bikes | Design |
Many of the criteria and types of bicycles overlap. The handbikes are usually designed as recumbent tricycles, transport bikes are available as two- and three-wheelers and velomobiles can also be pedelecs.
