Re: the perfect motorized bike?
Hi and welcome to the forum.
The Morini motors are great. I don't know how you are going to get it to work with any of the Sick-Bike-Parts freewheels or shift kits though. The drive on the Morini is on the left. You will need a Jackshaft of some sort to get it to the peddle drive side. The Sick-Bike-Parts Shift-Kit/Jackshaft won't bolt up to the Morini. You really don't need it though. That motor revs so high that a single gear is more than adequate.
Sounds like a great project!
