[bike_riders33]

Not sure if this is the right area for posting. Im newer to e-bike
im curious what would the cost for a battery that could go 100 miles at 10-20mph cost?
if i were to buy from aliexpress or alibaba would i be wrong on doing that? if it was usa > usa what would cost be? vs doing it from china
