消費者騎乘自行車時的人因考量，主要取決於踏板、座墊、握 把三者的形狀、尺寸及三者間的相對位置，三者對騎乘的操控方便性、安全性、與舒適性都相當重要。有關騎姿方面已有許多相關文獻研究，本研究係針對自行車握把操控的方便性與舒適性進行探討，希望對提升自行車性能品質有所助益。研究中將整體握把歸納為握把寬度、直徑、與向後彎折角度、剎車握桿尺寸、行程與配置角度、變速撥桿形式與配置角度等設計因素，以五部登山自行車配置現有不同之握把，依靜止、平坦、爬坡、下坡、轉彎等路況進行實際騎乘評估，以比較不同路況下騎乘者對不同設計的看法。由於在動態測試下並無法就每一設計因素予以變化進行測試，也無法掌握騎乘者手腕與握把之間的角度關係，因此另安排靜態測試，就握套直徑、握把寬度、與握把後彎角度作尺寸變化之探討，以得知騎乘者可接受的尺寸範圍；就手腕與握把角度關係，則安排靜止測試模擬水平騎乘與上下坡狀態下進行數值量測記錄，再予以統計分析。參與測試人員之手部人因尺寸亦均予以記錄，以分析瞭解手部尺寸與適當握把尺寸的關係。

The shape, size and related position of paddle, seat and Handle-bar are the most important design parameters for the safety, comfort and convenience of Mountain-bike(MTB) riders. this research is to study the design of MTB handle-bar from ergonomic viewpoint, and hope to help upgrade the riding quality of MTB . In this research the design parameters of a handle-bar are sorted into the width, diameter, and backward angle of handle-bar, the length,position, and angle of brake lever, as well as the position and angle of speed-swift lever. Five MTBs with different handlebars were tested by a group of riders on flat, up-hill, and down-hill roads, to compare the maneuverability and handling comfort of different handle-bars. Static test were carried out to find riders'' preferred size of single design parameter, such as diameter of grasp, width, and backward angle of handlebar, by varying the size of these parameters separately. Angles between riders and handle-bar were measured by simulating up-hill and down-hill conditions. Palm sizes of all riders taking parts in this test were recorded for analyzing the relation between palm size and the size of the handle-bar.
