The Qualisports Dolphin Plus is a folding electric bike with two hidden batteries, offering extended range! The main battery pack is built into the custom seat post, and the other is mounted inside the downtube. Total combined capacity of 840 watt hours, both packs are lockable and removable, includes a 3 amp quick charger. Available in three colors, but only one frame size. Adjustable handlebar and seat height provide a range of fit options. Sturdy joints and clasps, fairly stable when folded, magnetic clasp keeps it from coming unfolded. Base level Shimano Tourney 7-speed drivetrain with 14-28 tooth freewheel. Includes an integrated headlight and AAA powered rear light, a flick bell, and steel fenders to keep you dry. Powerful 20 amp sine wave controller supports the 500 watt planetary geared hub motor, keeping it smooth and quiet. Five levels of pedal assist activated by a cadence sensor, also has a trigger throttle and cruise control. Lots of optional accessories including front and rear baskets, pannier bags, and a seat post clamp lock. But, if you get this lock, you’ll have to manage two sets of keys. Smaller wheel size with high attack angle can feel jarring, and the unique seat post cannot be swapped for a suspension post. Some unboxing and assembly required.
