I already told a out when i was a kid and the little 3 speed we had but what got me going later in life, my 50s, was getting a job where i could ride to work. The first day was scary but i also had the feeling i was having a secret joy that no one else got to have. It made me so happy. The prominent bike in that time for me was a masi rando. Modern 700c bike. I eventually migrated to others but the masi was trouble free and really got me back in.
