Gotrax Dolphin
Budget step-thru city bike, UL 2849 · Reviewed by Drew · amazon.com live, Sept 28 2026
Why it scored a 71
At $549.99 the Gotrax Dolphin is a light step-thru city e-bike from a scooter brand with real US support and UL 2849 certification. Satisfaction leads at 86 and Value holds at 82, but Features drags at 55 and Quality at 60: the 280.8 Wh battery is the smallest in this group, good for about 15 miles on throttle, and the 365-day parts assurance keeps Warranty at 55. That adds up to 71, under the buy line, so it misses a recommendation mainly on range. It is for a rider who wants an easy-mount bike for short neighborhood errands and would rather have a certified battery than a big one.
