Have just acquired a Japanese Fracker Como mama cycle with a flat battery. I really like the style & some of the features of this bike & would love to get it up & working on a new battery. I don't have a charger for it either so will have to get one of those as well. It's a crank drive assist bike with a 26 volt 3.6 Ah Panasonic Li-ion battery that I have seen advertised on Japanese web sites. I'm looking for advice on what my options are re getting a new battery & charger, I'm confused with the advertised 26 volt rating as 24 volts seems to be the norm? can I replace with a new 24 volt battery & charger? I would prefer a 9 Ah instead of the rather small 3.6 which will entail re-siting the new battery which is not a problem to me. Any advice gratefully received.
