Technical Field

The invention relates to the technical field of bicycles, in particular to a heating bicycle handlebar based on carbon fibers.

Background

The human body senses cold at a temperature of about 15 degrees and senses frost at a temperature of less than 10 degrees. In winter, the weather is cold, the temperature in China is generally below 10 ℃, if no warm-keeping measures are taken, people feel uncomfortable, and the parts are exposed in too cold air for a long time to easily cause symptoms such as frostbite and chapping, so that the daily life is seriously influenced. Furthermore, with the development of shared economy, more people select bicycles to complete their short distance, however, research shows that nowadays, fewer people select the bicycles with warm gloves, so how to improve the bicycle handlebar on the premise of ensuring safety so as to heat and keep the hands exposed outside at a certain temperature without being frostbitten is a topic worthy of research.
