I have got an old Suffolk Engine that I want to put on a bicycle but I don't know what I'll need to make it drive the back wheel.
There is nothing on the main shaft.
Then you should look up post others have done with a 79 cc Predator engine. That way you can get some ideas of speed expectations and reduction requirements.
You can buy a tachometer/hour counter fairly cheap off eBay and Amazon. Then you'll know exactly what your engine is doing. The hour counter is a very good aid in maintaining maintenance schedules. Oil changes, air filter cleaning etc.

Here is a video that will give you some "inspiration"
The "clutch" build starts at about the 6:30 mark of the video. Lots of different names for this type of set up, I personally use the term "idler clutch". It is what I remember from a build of the late 1950s.
