The invention relates to a combined telescopic folding bicycle. A stand pipe support below a bicycle saddle 39 is changed into a double-stand-pipe support 28. A bicycle beam is changed into a telescopic tubular beam consisting of a first tubular beam 14, a second tubular beam 15 and a third tubular beam 16. Two vertical pipes on a double-vertical-pipe support 28 of the backrest type saddle 39 are connected with connecting frames 45 arranged on the two sides of the third-section tubular beam 16. And the two sections of handlebars 1 are arranged in the connecting box 2. And a connecting frame 6 below the vertical pipe 5 is connected with a connecting frame 7 arranged at the upper end of a handlebar 91. And the pedal device 11 is connected with a connecting frame 9 arranged on a head tube 8 above the front wheel. And the front part of the rear wheel bracket 23 is connected with the bottom of the third tubular beam 16 to form the backrest type bicycle. A pedal device 11 is detached from a connecting frame 9 on a head pipe 8 and then connected with a connecting frame 47 below the front portion of a rear wheel support 23, and a backrest type saddle 39 on a double-vertical-pipe support 28 is replaced by a riding type saddle 48. Therefore, the bicycle is converted into a riding type bicycle.
本发明涉及一种组合式伸缩折叠自行车,是把自行车车座39下方立管支架改成双立管支架28。自行车梁改成由第一节管型梁14,第二节管型梁15,第三节管型16组成的伸缩式管型梁。靠背式车座39的双立管支架28上的两个立管与第三节管型梁16两侧设置的连接架45连接。两节车把1装入连接盒2内。立管5下方的连接架6与把立91上端设置的连接架7连接。脚踏装置11与前轮上方的头管8上设置的连接架9连接。后轮支架23的前部与第三节管型梁16的底部连接,组成靠背式自行车。把脚踏装置11从头管8上的连接架9上卸下,再与后轮支架23前部下方的连接架47连接,把双立管支架28上的靠背式车座39换成坐骑式车座48。这样就转换成了坐骑式自行车。
