Dual batteries on a small folding e-bike? Qualisports says "sure, why not!" Having the dual battery option is nice if you want to maximize your range, but you might not want to ride that far since this is a small bike with no suspension... but even then it's nice to not have to charge up as often. Plus, the battery-hiding seatpost is extra thick which means you can raise it extra high; this combined with the telescoping stem make the Dolphin Plus surprisingly comfortable for what it is. The 500 watt motor feels pleasantly zippy due to the smaller diameter wheels, with a tried-and-true Shimano drivetrain for pedaling.
