An elderly passenger bicycle with a trackable position, the bicycle has a positioning device, which comprises a transmitting module, a power supply module, a power display module, a sensing module, a timing module and a micro processing The transmitting module can transmit the coordinate position of the walking vehicle； the sensing module can detect whether the old person leaves the safety range of the walking vehicle； the timing module can count the time when the old person leaves the safe range； the microprocessor separately and the transmitting module, The power supply module, the power display module, the sensing module and the timing module are electrically connected to receive and process the signals transmitted by the modules； after the positioning device is turned on, the sensing module senses that the elderly are not safe. In the scope, the transmitting module sends the coordinates of the bicycle to a communication device through a network system to control the position of the elderly and the helper vehicle to avoid loss or accident.一種可追蹤位置的老人助行車，該助行車具有一定位裝置，其係包含一發射模組、一供電模組、一電力顯示模組、一感測模組、一定時模組及一微處理器，發射模組可發射助行車的座標位置；感測模組可偵測老人是否離開助行車的安全範圍；定時模組可計數老人離開安全範圍的時間；微處理器分別與發射模組、供電模組、電力顯示模組、感測模組及定時模組電性連接，以接收及處理各模組所傳送之信號；俾開啟定位裝置後，感測模組如感測到老人不在安全範圍時，令發射模組透過一網路系統發送助行車的座標位置至一通訊裝置，以掌控老人及助行車之位置，避免走失或發生意外。
