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.

Priced at $1,899, this sits just under our affordable category. Is it worth the price tag? Well, let’s ..."
"If you are familiar with the Qualisports lineup, you would think this is just a Beluga with thinner tires. On the surface, this would appear correct, but the Dolphin has designed a new frame that adds the ability to hold a second battery. This dual battery configuration extends the riding range of up to 80 plus miles per dual charge. The second battery for the Dolphin Plus is a 48V 7aH lithium-ion battery capable of..."
"The move to hydraulic disc brakes is just awesome! They are both easy to use, whereas the right brake can be difficult if it’s a mechanical system because the wire rubs on the housing and can get gunked up over time. Both brake levers have motor inhibitors and offer adjustable reach. The brand of these parts isn’t super high end, but they worked well, and the smaller 160mm rotors gets a mechanical advantage becau..."
