Thanks much, going to order the 4amp ver since that is the old one's rating and only $20 more, charges 2 10 amp batteries in parallel. Any knowledge of the motor/controller , thinking 48 volts if it will take it
I need batteries, I checked on replacements cost almost as much as the 750 i spent on the bike, not sure this bike is worth it. Where are you located? maybe we can make 1 out of the 2 bikes. I am in the suburbs of Wash DC
