Any idea if this was used for a bicycle? Not sure if its off a bike or an exercise bike. Thanks//

Exercise bike. I have a very similar one that I modified to work on one of my bikes. The plastic wheel rest against the tire and when moving-shows your speed. It looks as if your wheel is broken though.They were used on 20" wheels though,so you could potentialy still use the spedo head and cable.

The speedometer head is same used on bikes also. Just has a different cable and drive unit.
