Hi, I started to notice Motorized bikes last year. I found a western flyer galaxy in my barn and away I went. Have build four since then. An Indian board track racer, a streched build 4 cycle and 2 China girls. I ride them also. I am 75 years old. Who says you can't learn an old dog new tricks. Great hobby. Have build old cars in the past. I will post pictures when I learn how.
