Exploring the Romatlink Dolphin E-Bike: A Comprehensive Review

Exploring the Romatlink Dolphin E-Bike: A Comprehensive Review

Introduction

Today, we dive into an in-depth review of the Romatlink Dolphin, an electric foldable bike that stands out for its impressive carrying capacity and range. Accompanied by my wife, we put this $1,300 e-bike to the test, exploring its various features and performance metrics.

Customization and Performance

The Dolphin allows riders to customize pedal assist levels from 3 to 9, adjusting the power for each level. We tested the speed differences at various power settings (20%, 40%, 60%, 80%, and 100%) and found that the speed limit can be adjusted in the settings for optimal control. The half twist throttle matches a top speed of 24 mph, similar to the pedal assist.

Speed and Acceleration

With two riders, the Dolphin nearly matched the speed of a single rider, only about a mph slower. The motor's reaction time can be adjusted in the settings, affecting how quickly power engages when pedaling. The throttle proved slightly faster than pedal assist, hitting 22 mph in a city block.

Comparison and Hill Climbing

We compared the Dolphin's acceleration with that of the Electric 3.0, noting a close match in the first 200 feet. The bike is rated to climb up to a 30% grade, though our tests on a 26% grade were challenging both with and without momentum.

Braking and Battery

The mechanical brakes were effective but required significant pressure for hard braking. When tested against the Electric 3.0's hydraulic brakes, the Dolphin's stopping distance was only marginally longer. The bike features a 48-volt 30 amp Samsung battery, offering an impressive range, especially for its price point.

Design and Comfort

The bike includes a standard Shimano SIS index 7-speed shifter and a Turny derailleur. Unique features like cruise control add to the riding experience. The handlebar adjusts to fit riders between 5'2" and 6'4", and the bike's overall design, including its 93 lb weight, is well-balanced.

Off-Road Capabilities and Overall Impression

The Dolphin is suitable for well-traveled trails, with a front fork and seat post suspension that handle bumps well. Our overall rating is 7 out of 10, considering the bike's basic feel but exceptional battery range.

Conclusion

The Romatlink Dolphin stands out for its incredible range, capable of reaching up to 100 miles on pedal assist. While it offers a basic ride and speed, its value lies in its range, making it an attractive option for those prioritizing distance over speed.
