關於我們About us
前進的力量:
自行車前進的力量來自雙腳輸出，舒適的騎乘有賴於平順的變換檔位。
平順的變換檔位:
讓乘騎者不用手指頻繁費力的切換檔位，以速度跟踏頻來實現變速檔位的自動更換。
自動變速:
自動變速在交通工具上已經應用很長一段時間，但在自行車上卻一直以手動變速器為主，目前AGS-M4是市場上唯一整合速度踏頻的自動變速系統。
Propelling Power:
The propulsion of a bicycle comes from the pedals, and a comfortable ride relies on smooth gear shifting.
Smooth Gear Shifting:
Riders don't need to frequently and laboriously switch gears; speed and cadence are used to automatically change gears.
Automatic Gears:
Automatic gearing has been used in vehicles for a long time, but bicycles have traditionally relied on manual shifters. Currently, the AGS-M4 is the only automatic gearing system on the market that integrates speed and cadence.
