Product Overview

Rolling through cityscapes and down neighborhood streets on the RoadRunner D4+ has been an exhilarating experience. Those with a thirst for speed and a penchant for robust build quality will instantly connect with this e-scooter. While heavy-set enthusiasts may feel right at home, those seeking a lightweight, easily portable option might need to steer clear.

Design and Build Quality:

From the first glance, the RoadRunner D4+ impresses with its sturdy frame and matte finish. The materials exude durability, a necessity for daily use. I was pleasantly surprised by the intuitive assembly process that was straightforward, even for a novice.

Overall Performance:

Whether it's a quick dash to the office or an adrenaline-fueled ride on the weekend, the D4+ does not disappoint. Its acceleration is snappy, propelling me to impressive speeds with ease. Navigating steep inclines? A breeze, thanks to its formidable hill-climbing ability. Braking is equally competent, though a tad abrupt at high speeds—something riders acclimate to over time.

The Motors & Battery:

The dual motors pack a punch, offering consistent power output that makes 34 MPH feel effortless. During my commutes and joyrides, the battery life held up admirably, aligning well with the advertised 40-mile range.

The Wheels & Braking:

Riding on various surfaces highlighted the wheels' versatility—comfortable yet firm enough for stability. Safety is paramount when cruising at high speeds, and while I had confidence in the mechanical brakes, I did yearn for a bit more finesse in their response.

Overall Handling:

Handling this beast felt natural after a few rides; however, its weight did become noticeable during longer journeys. Despite this, carving through bends and maneuvering around obstacles remained enjoyable experiences.

Maintenance and Repair:

Thankfully, maintenance was mostly straightforward due to accessible parts and clear instructions. For more intricate issues, customer service was helpful but expect some DIY work as part accessibility could improve.

Additional Features:

Thoughtful extras like quality electric gauges contributed to a seamless riding experience by keeping vital stats at my fingertips. While not groundbreaking in innovation, these features certainly polished my daily interactions with the D4+.


Considering everything from performance to comfort, my rating stands firm at 8/10. It lost points primarily due to its weight and braking system that could use some refinement.
