Centrifugal Clutch Friction Drive

I am new here and have a question. I built a friction drive bike and it works well, (YouTube - Motorized Mountain Bike) but I am thinking about putting on a centrifugal clutch. I dont have a pull start or anything. I simply start riding and then it fires up and I ride off into the sunset. My question is if I put on the Centrifugal Clutch how would I start it?

It would seem to me that with a centrifugal clutch you will need a pull start.
Thank's for the vid

Thanks. Seems it might be too much trouble. I will just ride it the way it is or find me a motor with a clutch already on it.
