Default Re: ECO Question - Electric vs Gas

However if you want to go longer distances then gas will probably be best. Keep in mind that here in OR the limit is 35cc< and 24 mph. But the bright side is that it does allow you 4 mph more in legal speed. A 4 cycle 35cc like the Robin or Honda will do that all day long also. The problem is how to transfer that energy to the bike and I have come to the conclusion that the best way to do so is with a friction drive. Reduction gearing systems just rob too much power from a smaller engine and also parasitic drag on the bikes conventional drivetrain which makes it less like a bike when you just want to pedal.

As far a the eco thing I don't have much of an opinion on that other than if you are conscious of reducing your overall usage of elec/fuel in a realistic way that is a good thing.
I think that's a good synopsis Mabman and I agree. BTW, I find it interesting what you've concluded with FD. If I remember right you used to think differently on that, no?
