Gotrax Dolphin 26in Electric Bike - Step-Thru City E-Bike

In this review the Gotrax Dolphin 26in electric bike is presented as a practical city e-bike for adults who want a simple, reliable ride with useful range and comfortable handling. The single biggest reason to consider it is the combination of a removable 280.8Wh battery with a 350W brushless motor that delivers up to 20MPH and allows riders to choose between pure electric or extended pedal-assist range. For commuters or casual riders seeking an easy-to-assemble, step-thru frame and adjustable fit, the Dolphin offers sensible performance without complexity.

Key Features

• 350W brushless motor: Provides a smooth top speed near 20MPH for confident city travel and quick acceleration from stops.
• Removable 280.8Wh battery: Detachable pack charges in about 5.5 hours and supports roughly 15.5 miles on pure electric mode for short daily trips.
• Pedal-assist with 5 levels: Expands range to more than 30 miles and gives riders granular control of effort and battery use.
• Shimano 7-speed system: Matches motor assistance to terrain and helps reduce leg strain on hills or longer rides.
• Comfort and safety components: Height-adjustable seat, angle-adjustable handlebar, front suspension, and dual disc brakes improve comfort and stopping power.
• Simple assembly and support: Most work is preassembled, tools and instructions are included, and the brand provides a 365-day parts assurance.

Who It's For

The Dolphin is well suited for urban commuters, new e-bike buyers, and recreational riders who want an approachable, step-thru frame and a mid-power motor that keeps speeds legal and predictable. Its removable battery and moderate pure-electric range make it practical for daily errands, short commutes, and mixed pedal-plus-assist weekend rides.

Riders who need very long ranges, high-speed performance above 20MPH, or heavy cargo capacity should look at larger battery or cargo-specific models. Also, those seeking full suspension or off-road capability beyond light trails may prefer a more specialized e-bike.

Pros & Cons

Pros

• Removable battery that is easy to carry and charge separately.
• Five pedal-assist levels and a boost mode for flexible range and reduced fatigue.
• Comfort-oriented fit with front suspension and adjustable controls for varied riders.
• Simple assembly process and supportive after-sales coverage for peace of mind.

Cons

• Pure electric range is modest at about 15.5 miles, so long rides rely on pedal-assist or a spare battery.
• Top speed and power suit city use but are not designed for high-performance or heavy off-road riding.
