Is there another reason your intentions call for a chain/sprocket besides wanting to pedal every so often at random times?Thing is, my intended use seems to point towards a chain / sprocket type of arrangements.
If I were you, I would jump right into buying a NuVinci kit from Staton, like this one. You'll get gas mileage at least as good as a GEBE kit, plus you'll still have a reliable chain that doesn't need to be replaced every so many miles... and you'll never have to remove anything to pedal freely.So basically I need something that can bring me up to / close to traffic speed for the later half and then can run on a median for the last mile or so.
I'm interested in someone with a GEBE kit who pedals every so often as well. I actually pedal quite a bit with my dual freewheeled hub. It's simple to start and stop, no switching anything or pulling a clutch... it's mostly all automatic. You can pedal without having to hold in a clutch lever and also don't have to mess with the clutch lever when starting & stopping. I can pedal to the corner store at about 12mph with a 20" BMX... then ride back with a beer in my left hand as I let the gas burn behind me.That means BY CHOICE I want to be able to peddle without the motor if I'm in the mood. With that in mind, do you think GEBE is the way to go? I mean, I'm not opposed to getting on and off the bike a time or two to engage / disengage the belt BUT I'm wondering if I might not be happier with a system that will "do it on the fly." Of course, I'm assuming that the sprocket / chain systems work like that.
