Bicycle frame, bicycle and method for producing a bicycle frame

摘要

Bicycle frame formed by a half-shell (1) made of a thermoplastic material. The half-shell (1) is fiber-reinforced at least in regions, and includes a cover element (2), which is, at least in regions, connected to the half-shell and preferably closes the half-shell.

主权项

1. Bicycle frame formed by at least one half-shell bicycle frame element comprising a thermoplastic material, which is fibre-reinforced at least in regions, and by a covering bicycle frame element, which is, at least in regions, connected to the half-shell bicycle frame element, and closes said half-shell bicycle frame element, wherein
a. either frame element comprises specific bicycle frame structural components comprising a bottom bracket and steering tube and is manufactured in a plastics injection-moulding process, b. at least one selected region of at least one of the frame elements is formed by at least one fibre-reinforced thermoplastic organic sheet which is backmoulded thereon, and c. the at least one fibre-reinforced thermoplastic organic sheet is arranged in a region of the said at least one specific structural component of the bicycle frame, wherein the half-shell frame element and the covering frame element are connected to one another by overlapping and/or mutually closely fitting joining portions, and wherein at least one heating element, which can be supplied with electrical power, is arranged in the region of the joining portions, the heating element being formed by at least one carbon fibre.
