Dino, you would need a much larger back sprocket, the motor would stick out one side and where would you put ya feets?
It can be done though, probably best to do it with some type of reduction gearing in between, this would pull the motor back into the centre, also check the motor direction and make sure your engine will make you move forward.

I care about where i put my feet, we have a large dog that kindly fertilises the back lawn for us :)
What size sprockets can you get, how much do you weigh and what is your wheel circumference or diameter?
your back sprocket would have to be much larger, just how big depends on your wheel circumference and the size of the front sprocket. Pocket bikes use #25 chain and have 6/68 gearing, you can get other sizes but they cost a bit more. If your wheel circumference is 1495mm then your acceleration would pretty much suck, especially if you are heavy, you can get 90 tooth scooter sprockets, i don't know what pitch they are or if it would clear your frame.
You could also use the "pedal thingy" as an intermediate gear train.

Dino, Your replies are very short and void of information,i predict this project would be a struggle for all of us. Why don't you just use one of your trick nuts and drive the back wheel, it is so much easier.
