When you're cycling, you feel like you have to keep your hands on the handlebars. If the frame is a 17 frame, you can still ride it improvised, but you need to adjust the saddle and seat tube. Method:

Rotate the seat tube 180 degrees and then orient the saddle again. At the same time, change to a shorter stem, which is the thing that holds the handlebar tube.
