I've looked through a lot of electric motorcycle conversions and they're really neat. Especially the fact you can use pricier batteries because you don't have to buy so many. Perhaps somebody can answer a question though, why do electric motorcycles never use gearboxes? Electric cars do, so it always seemed weird to me that motorcycle conversions never have them.
My guess is that for thier intended purpose 50mph is fast enough and a single speed keeps it simple and "cheap". For those of us that need to go faster for the freeway a 2-speed will be needed.
I am a little puzzled though that they didn't make this freeway capable for 12 grand. Geez, who wants a bike that can't get on the slab?
I'm still waiting for one with a 80 mile range at 65 mph. They're getting closer.
Try GPR. They have a supermotard style bike that will do a claimed 62 mph, and with lithium batteries has a 60 mile range. The base price for lead acid batteries is under $6,000. I bet that it comes in under $12K with lithiums.
