What to know before buying

Listing details to confirm

Range depends on mode. The listing separately claims 15.5 miles in pure-electric mode and more than 30 miles in pedal-assist mode, while the title also advertises a 70-mile maximum without explaining its conditions. Confirm which range applies to the selected configuration and riding conditions. The claimed 350W rated motor with 500W peak power is in the feature text, while the title also advertises 20 mph. These are listing claims, not verified performance. The listing gives minimum user height as 5.2 feet, which is an unusual format, so confirm fit before purchase.

Buyers looking for a 26-inch city bike with front suspension and seven-speed gearing.

Less suited to

Riders who need a verified range guarantee or are choosing primarily on the title's 70-mile figure.
Riders whose height or load may not suit the listed fit and weight limits without first confirming them.

Customer feedback describes a smooth, comfortable ride and positive impressions of the design, speed and weight. Battery life and durability are mixed, with reports ranging from good battery performance to rapid power loss, and from sturdiness to a failure on an early ride. This matters for a bike advertised with different mode-specific range estimates. The listing's claimed 22.2 kg weight and front suspension provide context but do not settle those customer concerns.

Positive themes

Customers praise the smooth ride, comfort, design, speed and relatively low weight.

Mixed feedback

Customers report mixed battery life, including both positive impressions and accounts of fast power loss.
Durability impressions vary, including reports of sturdy construction as well as a failure on the second ride.

Frequently asked questions

What range does the Gotrax Dolphin claim?

The listing claims 15.5 miles in pure-electric mode and more than 30 miles in pedal-assist mode. Its title also says 70 miles maximum but does not specify the conditions for that figure, so treat the range claims as mode-dependent and confirm the relevant configuration.

What riding modes are listed?

Pure electric, pedal assist and ordinary cycling without electric assistance are described. The listing also specifies five pedal-assist levels.

What motor and gearing does it have?

The listing identifies a 350W rated motor and a Shimano seven-speed system. A feature claim gives 500W peak motor power, so the peak figure should not be confused with the rated output.

What fit limits are provided?

The listed maximum weight recommendation is 264 pounds and minimum user height is 5.2 feet. Confirm that the height value and bike fit suit the intended rider.
