: 大家好
: 週六我剛剛從新店青潭河濱公園騎YouBike2.0 到淡水
: 沿途都是三檔
: 且腳感覺有一點踩空的感覺在騎
: 感覺速度不能再快了
: 全程還是花了110分鐘
: 請問一下大家
: YouBike2.0 與youbike 設計最高時速分別是多少呢
: 另外
: 如果是騎youbike
: 新店淡水花多久時間才算合格呢
: 謝謝大家

根據捷安特官網iNeed FunCity的規格來看
大盤是38T 飛輪是19T 後輪建大K193 26寸 直徑是55.9cm 圓周約長 175.5cm
後變沒意外是 SHIMANO NEXUS Internal Geared Hub Rolle Brake 3-speed
https://bike.shimano.com/en-SG/product/component/nexus-inter3/SG-3R75-B.html
3檔 後變速傳動比 0.632
大概得出虛擬飛輪約為 19 * 0.632 = 12.008T
如果你以每分鐘90轉踩踏
(38/12) * 90 * 60 * (175.5 / 100) / 1000
齒比 rpm mins 公尺 換成公里
大概可以得出時速為 30.0105 km/h
這是不負責任的計算而已
也許每個地區的YouBike設定都不同
答案也不會一樣
