Description

Technical Field

[0001] This utility model relates to the technical field of height-adjustable exercise bikes, and more particularly to a height-adjustable exercise bike. Background Technology

[0002] With the increasing awareness of fitness among the general public, the market size of exercise bikes continues to expand. According to statistics, the global exercise bike market size reached US$8.7 billion in 2023, and is expected to grow at an average annual rate of over 6.5% in the next five years. In the domestic market, home exercise bikes account for over 70%, and users' demands for comfort, functionality, and personalization of the equipment are becoming increasingly prominent. Among existing exercise bike products, models with height adjustment functions account for less than 30%, and these are mostly concentrated in high-end models. The problem of limited functionality in mid-to-low-end products is prominent. Existing low-end exercise bike models rely on manual removal and bolt adjustment, which is cumbersome and takes 5-10 minutes per adjustment. Furthermore, installation errors can easily lead to structural instability. Additionally, the handlebar adjustment method on existing exercise bikes often uses dampers, which is quick but can cause sudden rotation of the handlebars during riding due to the significant force applied, posing a safety hazard. Therefore, these issues need to be addressed. Utility Model Content
