The dolphin needs more torque when… The dolphin needs more torque when using throttle, also needs faster acceleration, takes too long to come up to speed. The headlight wire is not long enough for proper installation of front rack. So you wind up losing space in front rack because of headlight. Other than those two issues it’s a pretty solid bike and decent value...

Awesome bikes! Purchased a Qualisports Dolphin+ after spending many hours of research, comparing different brands and reading reviews. Liked it so much, we ordered a Model 5 for my wife. The bikes are beautifully made and include things we see as important if you are considering an e-bike; hydraulic brakes and NO quick release wheels. These are both safety items we looked for and Qualisports is one of few mfrs that do both of these! Looking forward to many years of enjoyment from these bikes.

Love the bike Love the bike, great quality beautiful black paint. Real human support was easy to obtain. Company willing to support and help with my trouble. Will consider purchasing two more for family members in the future (after they sell eS ooters) and highly these recommend these bikes.

Great customer service Customer service responds quickly and efficiently. This is the 2nd time I've contacted them and each time a quick and very satisfactory solution has been found. I've been driving a Dolphin for 3 years now, commuting almost every day, and I'm very happy with it.

Wonderful bike, very happy--but tough set-up Customer service was always attentive and helpful. Just got my bike 2 days ago, and took the first ride today--love it! Set up was a bit frustrating--the included tool kit did not have all the correct size allen wrenches for the job (but fortunately my husband did). The only reason I didn't give 5 stars is due to the very brief owner's "manual," which is really a pamphlet, and other sketchy diagrams/information. Had to watch and read several things online to figure out how to set up and operate the bike properly.
