Bike is decent but don't expect any promised extras.

Bike is good. It bothers me that I was promised free racks. The rear one arrived after I contacted them, but still have not received the front one and have received no response. The free racks was one of the few reasons that I purchased this over other options. I guess I fell for the marketing lies.
As with all things: Caveat emptor - "Let the buyer beware".
The bicycle is fine, just sad about the lies and lack of effort to respond or completely and properly fulfill the order.

Best Electric Bike I've ever had.

First off everything is perfect on the bike . Absolutely no damage with shipping at all. Everything works perfectly.
I have had 3 other e-bikes before the Dolphin. All of them were 750 watt bikes and the top speed of all of them are about the same. But the Dolphin has much more torque the the others. I am 6' 2" and 290 lbs and live in a quite hilly area. (East Tennessee) And the other bikes I had to peddle like crazy to get up these hill. Not with the dolphin. I fly up these hills with little to no peddling. And I love the giant battery. Thanks to Romatlink.
