Abstract
A folding bicycle includes a first frame section; a second frame section movably mounted to the first frame section so that the first and second frame sections may be moved relative to each other from an unfolded position to a folded position; a front wheel mounted to the first frame section; a rear wheel mounted to the second frame section; a chainset mounted to the first frame section and including one or more chain rings; a rear hub mounted to the second frame section; a chain extending around and between the one or more chain rings and the rear hub; and a chain retainer fixedly mounted to the first frame section and defining a gap between the chainset and the chain retainer to maintain engagement between the chain and the chainset when the folding bicycle is in the folded position.

A folding bicycle comprising:
- a first frame section;
- a second frame section movably mounted to the first frame section so that the first and second frame sections may be moved relative to each other from an unfolded position to a folded position;
- a front wheel mounted to the first frame section;
- a rear wheel mounted to the second frame section;
- a chainset mounted to the first frame section and comprising one or more chain rings;
- a rear hub mounted to the second frame section;
- a chain extending around and between the one or more chain rings and the rear hub;
- and
- a chain retainer fixedly mounted to the first frame section and defining a gap between the chainset and the chain retainer to maintain engagement between the chain and the chainset when the folding bicycle is in the folded position.
A bicycle comprising:
- a frame;
- a chain set;
- a front wheel and a rear wheel each mounted to the frame;
- a hub gear mounted to the frame;
- and
- an electric motor,
- wherein, the electric motor is operably connected to the hub gear by way of a beveled gear arrangement, and
- wherein, the hub gear comprises a first sprocket and a second sprocket, the first sprocket is connected to the chain set by way of a first driving member and the second sprocket connected to the rear wheel by way of a second driving member such that when the electric motor is engaged, the second sprocket is driven by the electric motor to drive the first sprocket and consequently the rear wheel by way of the second driving member and when the electric motor is disengaged, the first sprocket is driven by the chain set to drive the rear wheel and the second sprocket is disengaged.
