yes I rode for many years with a suicide clutch and a jocky shift --jockey shift is right off the trans behind your left leg.. clutch is usually chain from trans area to front down tube then a pedal all that replaced the mouse trap and tank shift..
yes I am older than dirt ..
bmr is absolutely correct, it is a suicide clutch (foot clutch) with either a tank shift or jockey shift. You'll hear it called a suicide shift, but that is not correct. Stopping can be a little tricky especially on hills. Also if your foot slips off of the foot clutch in the rain.
Total blast to ride!
