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...

Love my Dolphin+ and excellent customer service! I was at first skeptical ordering from a brand I've never heard of. I've been looking for a compact folding ebike and the Dolphin+ checked all of my needs. I would like to acknowledge the customer service has been outstanding. From general questions, to issues or concerns, they've answered all my questions and provided solutions.Thanks again Qualisports!

Fantastic customer service Fantastic customer service. Fast response. Very helpful. Items shipped quickly and accurately.

The quality of bike is next level The quality of the bike is unparalleled- truly a premium mountain bike- nothing is compromised with the folding design. The customer service years after purchase and much use is just as good as day one. Thank you for the best bike and customer service.

I like my Volador I like my Volador! There were delays in production over the winter but QS compensated with free accessories. Liz Xu ,marketing manager, kept me informed of the bike's progress to delivery. It arrived in good shape except the rear fender was dented during shipping. They have offered to pay for repairs. I haven't started looking for who can un-dent it. Very happy with the bike so far. Quick basic setup and everything is working properly.
