Qualisports Dolphin Plus E-Bike Summary

Today, we’re diving into the fantastic world of the Qualisports Dolphin Plus, a dual battery folding electric bike. And to make this review extra special, I’ve got my mom, Camille, joining me! She’s super excited to give this a spin. The Dolphin Plus is designed to be compact and user-friendly, especially for petite riders like my mom. It’s perfect for city commutes, and with its foldable feature, it’s incredibly easy to store.

Priced at $1899, the Dolphin Plus comes with optional racks and a locking seat post clamp. The assembly was pretty straightforward, thanks to their detailed unboxing video, which is a huge plus if you’re not particularly handy with tools. Most of the assembly tools are included, though I did use my own screwdriver for a better grip.

One unique feature of this bike is its dual battery setup. It includes a primary 504Wh battery and a secondary 336Wh battery, giving you a total of 840Wh. This setup ensures a balanced weight distribution and an impressive range, almost a kilowatt-hour of capacity! However, a notable trade-off is that the seat post battery can’t be replaced with a suspension post. The bike doesn’t have a suspension fork either, so the ride might be a bit bumpier compared to full-size bikes with larger wheels and suspension.

The Dolphin Plus has a practical design with a second internal downtube battery, which also has a USB charging port. This dual battery setup is ideal for those who want extended range without compromising on convenience. Just a heads-up, extreme temperatures can affect battery performance, so keep your bike in a moderate environment to ensure optimal battery life.

The bike features 165mm crank arms, a 52-tooth chainring with a plastic guard to keep your pants clean, and a basic 7-speed Shimano Tourney drivetrain. The 500W hub motor provides decent power, especially combined with the smaller 20-inch wheels for better torque. While the hub motor is not the torquiest, it’s smooth and efficient, perfect for city rides. The hydraulic disc brakes with 160mm rotors offer excellent stopping power, which is crucial for safety.

Camille loved the adjustable handlebar and saddle height, making it easy for her to find a comfortable riding position. The plastic folding pedals, although not the sturdiest, do save space when storing the bike. The 20×2.3-inch tires provide stability and cushioning, but they lack reflective sidewalls, so make sure to add some reflective gear for nighttime rides.

The Dolphin Plus comes with a comprehensive one-year warranty and uses high-quality Samsung battery cells, which adds to its reliability. Installing the optional racks and fenders was a bit tricky, but manageable with some patience. The front basket and headlight setup could use some tweaking to avoid interference.

The bike’s LCD display is grayscale, clear even in bright sunlight, and features a USB port for charging devices. The throttle is constrained by the level of assist you choose, which is a bit of a safety feature. However, it would have been nice if it could be activated without pedaling for more convenience.

In conclusion, the Qualisports Dolphin Plus is a fantastic option for those looking for an affordable, compact, and versatile folding electric bike. With its dual battery system, decent motor power, and practical design, it’s a great companion for urban commuting and leisurely rides. My mom, Camille, gave it a thumbs up for its ease of use and comfort. Stay safe and ride on!
