That's a class act you have there !!
A bike like that would deserve a Morini I think
I'm glad you like my bike! I think the Morini engines are top quality but I think for this bike this is a better choice. The best choice would be Jim's engine of course and I look forward to when he has them ready. I will be certain to provide updated photos if that should come to pass
The Morini is wider and there is no jackshaft kit for it. Negating the benefit of the Nuvinci hub. It would have to be mounted higher and the motor mounts would be completely different. Due to its width it would probably require a special wide pedal kit as well. It would be a completely different bike and probably wouldn't look as nice since the placement and proportion of the components wouldn't have the same flow or balance. Undoubtedly the increased horsepower would add some challenges and the aluminum frame would probably require reinforcing in key spots. (not necessarily a bad problem
The motor that is on this bike is no longer the $200 Chinese special it once was. It has been worked on for many hours. It has been ported, polished, tuned and adjusted and now it is a powerful, reliable thing of joy. At their core the Chinese motors are really quite remarkable both for their simplicity and for how much you actually get for your money. Everything you need to know can be found on this forum but if you spend some time tweaking them you actually end up with a pretty decent power-plant.
