When you're out shopping for the Dolphin electric folding bike, there's often one big question: Should I go for the single-battery version or splurge on the dual-battery Dolphin Plus? &“What made you decide to buy—or consider buying—the Dolphin Plus?” --Many owners answer: “It offers all the features I wanted while still keeping the weight under 60 lbs, which means even someone like me, a retired person, can easily lift it into my truck.” These riders place a high value on the balance between performance and weight. Some have compared more than ten folding e-bike models on the market, but in the end, they chose the Qualisports Dolphin Plus for its manageable weight. Fully equipped with fenders and both batteries, the Dolphin Plus weighs 55.8 lbs. That’s not exactly light, but it’s far from heavy either. However, if you add front and rear rack, or a crate full of soda—the weight can climb past 65 lbs! Let's first take a look at the differences between STD and PLUS. Quick Specs Feature Dolphin STD Dolphin PLUS Battery 48V 10.5Ah 48V 17.5Ah Removable Battery ✅ ✅ Brake Hydraulic Hydraulic Brake Cut-off ✅ ✅ Motor 500W 500W Gears Shimano 7-Speed Shimano 7-Speed Weight 51.5 lbs 55.8 lbs Range 55+ miles 80+ miles Why Riders Choose the Dual-Battery Dolphin Plus 1. Go Farther Without Worrying About Running Out of Juice The Dolphin Plus can go up to 80+ miles on one charge when you use both batteries. That's great for long commutes, weekend getaways, or just exploring without having to stress about where to charge next. Whether you're cruising on the beach boardwalk or riding in the city bike lanes, that extra battery power gives you more freedom. 2. Surprisingly Light When You Need It You might think adding another battery would make the bike heavier all the time. But here's the thing: both of the Dolphin Plus batteries can be taken out and used on their own. If you want to carry a lighter load, just leave the seatpost battery at home and use only the frame battery.(Yes, you can use a seatpost with the same diameter but without a battery) Taking out the seatpost battery cuts off almost 8 lbs, so it's easier to lift the bike into your truck bed, car trunk, or even your RV. 3. A Portable Power Bank on Wheels The frame battery isn't just for powering the bike. It also has a USB output that can charge your phone, camera, drone, or LED lights. That makes it a great companion for camping trips, photo shoots, or emergencies. Smart Charging for People on the Go For RV owners or people who like to take road trips, the Dolphin Plus is awesome. With Qualisports RV charger, you can charge one battery in your vehicle while you're riding with the other. That way, you always have a charged battery ready to go—no waiting around, just more adventures. Upgrade Options Can I Upgrade a Single-Battery Dolphin? Yeah. You can buy the Dual Battery Kit from Qualisports. It comes with the frame battery and a converter. How Does the Bike Switch Between Batteries? When the frame battery is being used, it powers the bike first. Once it runs out, the system automatically switches to the seatpost battery. Is It Safety-Certified? Definitely. The Dolphin Plus and both of its batteries are UL 2271 & UL 2849 certified for safety and reliability. How to turn on the frame battery? Open the Dolphin Folding Electric Bike frame and press the button on the frame battery. Please note that the frame battery does not turn off automatically. You must manually turn off the battery after use. --https://youtu.be/_xMLkWPxPjk?si=eIsnakzzEVvY1pWo Who Is the Dolphin Plus For? Commuters who want to travel farther without having to charge every day. Travelers who take their bikes on RV trips, boats, or private planes. Seniors and Casual Riders who want a good balance of power, range, and a bike that's easy to handle. Adventure Lovers who like to power their gadgets like cameras and lights while they're out riding. Final Thoughts If you only ride short distances and want to keep your bike as light as possible, the single-battery Dolphin STD might be all you need. But if you're into longer rides, having a backup power source, and more flexibility, then the Dolphin Plus dual-battery version is worth the money. Key Takeaway: The Dolphin Plus isn't just a bike that can go farther. It's a folding e-bike that's flexible, ready for travel, and packed with power. It can fit into your lifestyle.(Note: The seatpost without battery is custom-made and is not currently listed on the Qualisports website.)  

The scent of sunscreen on warm asphalt, the rhythmic chirp of cicadas, the sheer freedom of an open path ahead – summer whispers adventure. Yet, for years, my own summer explorations felt limited. Hiking was strenuous in the heat, the car trapped me in traffic and parking nightmares, and my old traditional bike? Let’s just say mounting it felt less like grace and more like a precarious gymnastic feat I’d rather avoid after 50. Then, I discovered the magic of a well-designed folding e-bike, specifically my Qualisports Volador, and it genuinely transformed how I experience the season. Summer Riding: Not Just for the Lycra-Clad Young Let’s be honest, the classic image of a cyclist often involves spandex and intimidating hills. But summer exploration shouldn’t require Olympic training, especially for us enjoying the wisdom (and perhaps slightly creakier knees) that comes after 40. The beauty of modern electric bikes, particularly compact folding ones, is how perfectly they align with the desires of active, independent adults: Effortless Exploration: Imagine gliding along a coastal path, feeling the cool breeze without drenching your shirt in sweat. Or spontaneously deciding to explore that charming farmers’ market a few towns over, knowing the electric assist will effortlessly get you there and back, even with bags full of fresh peaches and local honey. The Volador’s pedal-assist and pure electric modes turn “maybe” into “let’s go!” Convenience is King (or Queen!): No wrestling a heavy bike onto a car rack. No worrying about secure parking at your destination. The Volador folds down in seconds to a remarkably compact 32.7" x 15.8" x 26.4". It tucks neatly into my SUV trunk, slides into a corner of my condo, or even rolls beside me like luggage into a cafe. This freedom from logistical headaches is pure summer bliss. Safety and Comfort First: This was non-negotiable for me. The Volador’s low-step frame is a revelation. I simply step through comfortably and settle onto the supportive saddle – no awkward, potentially wobbly high leg swings required. Combined with its intuitive handling and stable ride, I feel confident and secure on every outing. The Shimano 7-speed gears mean I can always find the perfect pedaling resistance, whether tackling a gentle incline or cruising flat terrain. Why the Volador Feels Like It Was Made for My Summers My search wasn’t just for any e-bike; it was for the right partner for this stage of life. The Volador hit every note: Light Enough, Powerful Enough: At 38 lbs, it’s manageable to lift folded, especially compared to many bulkier e-bikes. Yet, don’t let the weight fool you. Its robust motor delivers a smooth, zippy ride up to the perfectly legal and safe 20 mph, making even longer excursions feel breezy. Range for Real Adventures: That 30+ mile range isn’t just a number on paper. It translates to a full day exploring vineyards, a leisurely loop around the lake with lunch stops, or multiple errands across town without a hint of “range anxiety.” I simply recharge overnight, ready for the next day’s possibilities. Versatility is Vital: Some days I want a light workout – the pedal-assist lets me get my heart rate up without exhaustion. Other days, especially when the summer sun is blazing, I appreciate the pure electric throttle for a sweat-free arrival. And the cruise control mode? Absolute genius for relaxing on those long, straight scenic paths. Built for Mature Riders: Beyond the low step, the overall geometry feels stable and upright. The controls are intuitive, the display is clear, and the ride quality smooths out minor bumps, making it exceptionally comfortable for longer rides – essential for keeping joints happy. More Than Just a Bike: It’s a Summer Lifestyle Upgrade Owning the Volador hasn’t just given me transportation; it’s given me back a sense of playful independence. I find myself seeking out new bike paths, planning weekend excursions to quaint towns accessible via rail-trails, and simply enjoying the sensory delights of summer at a human pace – the smell of blooming jasmine, the sound of kids laughing in sprinklers, the warmth of the sun on my arms. It’s reconnected me with the simple joy of being out there, without the limitations I’d started to accept. Your Summer of Easy Adventure Awaits If you’re an active 40+ individual looking to reclaim the effortless joy of summer exploration, to add spontaneity and convenience to your outings, and to do it all with comfort and style, I can’t recommend the Qualisports Volador enough. It’s not just an e-bike; it’s a passport to rediscovering the warmth, beauty, and freedom of the season on your own terms.

As the sun rises over a secluded mountain range or a coastal highway, RV travelers know that true freedom lies not just in the journey but in the ability to explore beyond the confines of their mobile home. At Qualisports, we’ve engineered the Dolphin folding e-bike to redefine what it means to travel, efficiently, and joyfully. Here’s how this compact powerhouse addresses the unique challenges of RV life while elevating your adventures. Unmatched Range & Dual-Battery Flexibility: Conquer the Unknown For RVers, every mile off-grid is a treasure. The Dolphin’s optional dual-battery system delivers up to 80 miles of assisted riding—enough to explore remote trails, coastal towns, or national park loops without range anxiety. At a total weight of under 56 lbs (including both batteries), it strikes a rare balance between endurance and portability. But the innovation doesn’t stop there. The frame-integrated battery doubles as a portable power station, featuring a USB port to charge phones, cameras, or even a campsite speaker. Imagine capturing sunset photos at Joshua Tree without worrying about your devices dying—your e-bike becomes a lifeline. Power Meets Precision: Tackle Any Terrain with Confidence RV roads often lead to unpredictable paths: gravel, steep inclines, or winding forest trails. The Dolphin’s 500W continuous/750W peak motor provides torque-rich acceleration, while the Shimano 7-speed drivetrain ensures seamless gear transitions. Whether you’re climbing a 15% grade hill in Sedona or cruising flat lakeside paths, this system adapts to your pace. Pro Tip: The motor’s peak power isn’t just for hills—it’s a safety feature. When merging onto busy roads near RV parks, that burst of speed helps you navigate traffic confidently. Space-Smart Engineering: Designed for Compact Living Space is sacred in an RV. The Dolphin’s 6061 aluminum mid-step folding frame achieves two feats: Universal Fit: A low standover height accommodates riders from 5’2" to 6’2", making it ideal for families or groups. 3-Step Fold: Collapse it into a 33" x 14" x 28" footprint in under 10 seconds—small enough to tuck beside a dinette or under a bed.Unlike bulkier e-bikes, this design eliminates the “where do we store it?” debate. Plus, the rust-resistant aluminum frame withstands coastal humidity or desert dust storms. Charge Faster, Explore Longer: No Outlet? No Problem Dead batteries sabotage spontaneity. The Dolphin’s 54V/3A fast charger replenishes 70% capacity in 2.5 hours—about the time it takes to cook lunch at your campsite. For off-grid warriors, the optional RV DC charger plugs directly into your vehicle’s 12V system, turning driving hours into charging opportunities. Safety First: Certified Reliability You Can Trust At Qualisports, we understand that adventure thrives on confidence—especially when it comes to powering your journey. Both of the Dolphin’s dual batteries are rigorously tested and certified under the SGS UL2849 standard, the gold benchmark for e-bike electrical safety. This certification ensures: Overcharge/Overheat Protection: Intelligent circuitry prevents battery damage during fast charging or extended RV DC charging sessions. Short-Circuit Resistance: Built-in safeguards maintain stability even in humid or dusty environments common to RV routes. Long-Term Durability: UL2849 compliance guarantees the batteries withstand vibrations from rough roads, ensuring consistent performance over thousands of miles. For RV travelers, this isn’t just a technical detail—it’s peace of mind. Whether you’re relying on the hidden frame battery as a campsite charging hub or pushing the 80-mile range limit in remote areas, the UL2849 certification means your power source is as trustworthy as your sense of adventure.
