In-depth review
The Dolphin is the e-bike for riders who want a normal bike with help: a step-through aluminum frame, 26 in wheels, Shimano 7-speed and a 350 W motor capped at 20 mph (Class 2). It's UL 2849 certified and shipped and sold by Amazon.
The 281 Wh battery is small; plan on 12–20 real-world miles. One owner notes the motor struggles uphill for heavier riders without pedaling.
A one-year owner who rides six days a week says the battery still performs like new.
Owner reviews
4.3★ from 294 ratings (87% four or five stars). Owners praise easy assembly and reliability; some say hills need pedaling.
Wanted a Class 2 legal in her state; very happy with this one.
— Jessica-Star, Amazon.com
Good quality, but uphill without pedaling it struggles above about 150 lb.
— RH, Amazon.com
A year of near-daily rides and the battery still lasts like day one.
