Rad Power RadExpand 5 Review: The Rugged, Foldable E-Bike
In a world where electric bicycles are rapidly transforming how we move through cities, rural areas, and outdoor trails, not all models are created equal. Some are built for speed, others for luxury—but if you’re searching for transportability, power, and practicality, the Rad Power RadExpand 5 demands attention. This foldable fat-tire e-bike combines rugged design with everyday usability, offering riders a capable companion that can go from urban streets to off-road paths—and then fold up neatly when you’re done.
The RadExpand 5 is more than just a folding electric bike. It’s Rad Power’s most compact and versatile model, perfect for commuters, RV travelers, or anyone short on storage space but unwilling to compromise on performance. With a powerful 750W rear hub motor, 672Wh lithium-ion battery, and 20-inch fat tires, this e-bike is built to handle varied terrain while keeping the ride smooth and steady.
In this detailed article, we’ll walk you through everything you need to know about the Rad Power RadExpand 5. From battery life and motor capabilities to comfort, build quality, and real-world performance, we’ll break it all down. You’ll also learn about its ideal use cases and whether this rugged folding e-bike is worth your investment. Whether you’re a seasoned e-bike rider or considering your first purchase, this review will help you decide if the RadExpand 5 is the right fit for your lifestyle.
Built Tough, Folds Easy
One of the standout features of the RadExpand 5 is how it manages to be both rugged and convenient. Folding e-bikes often fall into the trap of sacrificing build quality for portability, but that’s not the case here. Rad Power Bikes has delivered a model that feels strong and stable, even over rough terrain. The fat tires add an extra layer of cushioning, which is especially useful when navigating bumpy city streets or light trails.
Despite its tough frame, the RadExpand 5 folds down with relative ease. This makes it perfect for apartment dwellers, those who commute using public transport, or RV travelers looking to stash a compact ride in a tight storage space. The fact that you get this level of durability in a foldable format is what sets the RadExpand apart from many traditional e-bikes in the same price range.
Power Where It Counts
Under the hood, the RadExpand 5 is powered by a 750W rear hub motor that delivers ample torque and speed for most riding scenarios. With a top speed of 20mph, it falls into the Class 2 e-bike category in the United States, making it legal for most bike paths and city streets without requiring a license. The motor engages smoothly and, while it doesn’t offer lightning-fast acceleration like some high-end models, it provides reliable and consistent power on hills and straightaways alike.
The 672Wh battery offers a range of up to 45 miles, depending on your riding style and pedal assist level. That means you can handle your daily commute, a grocery run, or even a weekend adventure without constantly worrying about recharging. The battery is removable, allowing for easy charging at your desk or in your home—especially helpful if you park your bike outdoors.
It also features a 4-hour charging time, which is faster than many models in the same category. So even if you drain it on a morning ride, you’ll be ready to hit the road again by the afternoon.
Control and Handling That Inspire Certainty
Handling is a big deal when it comes to folding e-bikes, especially ones with smaller wheels. The 20-inch fat tires on the RadExpand 5 provide a more confident ride compared to narrow, city-focused folding bikes. These wider tires are not just for aesthetics—they genuinely improve balance and control, especially when you’re riding on uneven surfaces or gravel paths.
The 7-speed RD-M26 derailleur drivetrain gives you enough gearing options to handle light inclines and diverse terrain, although this isn’t a bike built for steep mountain climbs. It’s more about versatility and comfort—and in that respect, it performs very well. The hydraulic disc brakes offer excellent stopping power, giving riders peace of mind when navigating busy urban areas or descending a slope.
The Rad Power RadExpand 5 also includes a clear display, though some users have noted it could be more intuitive. While it shows the essentials like speed, battery level, and pedal assist mode, the interface isn’t as refined as some competitors. Still, considering the price and overall package, it’s a minor trade-off most riders can live with.
Comfort for the Long Pull
Just because the RadExpand 5 is compact doesn’t mean it sacrifices comfort. The upright riding position, adjustable seat post, and wide saddle make it suitable for longer rides. However, taller riders may find the geometry a bit tight. If you’re over six feet tall, it’s worth taking a test ride before making a commitment, as the compact frame and wheelbase may not offer the leg extension you’re used to.
That said, the bike excels in providing a smooth ride for most average-height adults. The fat tires, combined with the frame geometry, absorb many of the bumps and vibrations you’d typically feel on less robust e-bikes. It’s a smart choice for anyone who plans on riding daily, especially on imperfect surfaces.
Thoughtful touches like front and rear lights, full fenders, and a chain guard also enhance the everyday usability of the RadExpand 5. It’s clearly designed for real-world riders who need more than just a weekend toy.
Designed for Everyday Adventures
The Rad Power RadExpand 5 truly shines in day-to-day scenarios. Whether you’re commuting to work, grabbing groceries, or heading out for a weekend ride, it adapts well to a variety of tasks. Its combination of fat tires, a 750W rear hub motor, and a reliable 672Wh battery provides a comforting mix of power and stability—especially for those who value utility in a compact e-bike.
The fact that it folds makes it a favorite among RV travelers and city dwellers alike, allowing for easy transport and storage without sacrificing performance. Even when riding at its full 20mph top speed, the RadExpand 5 maintains a smooth, controlled feel. Power delivery is steady and non-jerky, making it approachable for beginners. For experienced riders, it offers a predictable and safe experience across multiple surfaces—from pavement and bike lanes to packed dirt or gravel trails. The fat tires are a huge asset here, giving the bike reliable grip and softening road imperfections.
Built-In Practicality
One of the most appealing aspects of owning the RadExpand 5 is its practical design. It’s not just about getting from point A to point B—this e-bike is built with real-world riding in mind. The rear rack provides ample space for bags, groceries, or gear, while the full-coverage fenders protect you from mud and water splashes, especially helpful in unpredictable weather. The chain guard is another welcome touch, helping prevent grease stains or chain tangles when commuting in everyday clothes.
The included lights, both front and rear, are bright enough for early morning or evening rides, increasing visibility and safety. These features, while not flashy, elevate the RadExpand 5 into something that feels less like a gadget and more like a dependable daily vehicle. In an age where more people are turning to e-bikes as car replacements, these seemingly small additions play a big role in creating a seamless riding experience.
Portability Comes at a Cost
While the folding design of the RadExpand 5 is undeniably convenient, it doesn’t come without trade-offs. At 29kg (around 64 pounds), it’s far from lightweight. Carrying it up stairs or lifting it into a vehicle can be challenging, especially if upper body strength is a concern. Once folded, the bike becomes more manageable in terms of space, but physically moving it still requires some effort.
This weight also affects the ride. Although the motor does a good job of offsetting the heaviness while in motion, you’ll notice the bulk more when coasting or pushing the bike manually. That said, this weight contributes to the RadExpand 5’s planted feel. Unlike lighter folding bikes that can feel flimsy or twitchy, the RadExpand inspires confidence with its sturdy construction.
User-Friendly, Though Not Tech-Heavy
In terms of onboard tech, the RadExpand 5 is fairly straightforward. It includes a display showing speed, battery life, and pedal assist level, but compared to more advanced models with Bluetooth connectivity or smartphone apps, it feels basic. Riders looking for a high-tech dashboard or GPS integration may be disappointed—but for many, simplicity is an advantage. There’s less to fiddle with, fewer distractions, and a shorter learning curve.
The pedal assist system is intuitive and easy to use. You can choose between several levels of assistance depending on how much help you want from the motor. There’s also a throttle available for when you want to cruise without pedaling—especially helpful at traffic lights or when you’re tired. The RadExpand 5 balances manual control with electric support very well, making it suitable for both beginners and experienced riders.
Perfect for a Wide Range of Riders (But Not All)
While the RadExpand 5 is designed to accommodate most adults comfortably, it may not be ideal for taller individuals. Due to its compact folding frame and 20-inch wheels, riders over six feet tall might find the riding position a bit cramped, especially on longer trips. Adjustments can be made to the seat and handlebar height, but the frame only allows for so much flexibility.
On the other hand, average-height riders and those on the shorter side will likely find this e-bike very accommodating. The step-thru frame design makes it incredibly easy to mount and dismount, which is especially appreciated by older riders or anyone with mobility challenges. The upright geometry promotes a comfortable posture that doesn’t strain the back or wrists, helping reduce fatigue over long distances.
A Competent Choice for the Proper Rider
Ultimately, the Rad Power RadExpand 5 is a competent, well-rounded e-bike that shines in versatility. It’s not the most high-tech option, nor is it the lightest folding bike on the market—but it delivers where it matters most. Riders who prioritize durability, daily usability, and a reliable mix of comfort and power will find a lot to love here. The folding frame makes it unique in the Rad Power lineup, appealing to those with specific storage needs or lifestyles that demand a compact yet capable ride.
Real-World Execution and Rider Encounter
In real-world scenarios, the RadExpand 5 proves to be more than just a spec-sheet winner—it’s a practical companion. From bustling city streets to relaxed countryside routes, its performance remains consistent. The 672Wh lithium-ion battery reliably delivers up to 45 miles on a single charge, and the 750W rear hub motor offers ample torque for hills and quick starts.
The fat 20-inch tires absorb shocks and offer grip on a variety of surfaces. Whether you’re riding on loose gravel or wet asphalt, the RadExpand 5 remains grounded and easy to control. Riders report that the hydraulic disc brakes are strong and reliable, particularly when descending or making quick stops. Combined with the 7-speed derailleur and pedal assist system, the ride feels smooth and responsive wherever you take it.
Consolation That makes You Want to Ride More
The RadExpand 5 doesn’t just get you to your destination—it encourages you to keep riding. Thanks to its upright position and step-thru frame, you’re less likely to feel sore or strained even after long rides. The saddle strikes a good balance between support and cushioning, and the adjustable handlebars help you find a comfortable setup. Many users report that they ride more often simply because the bike feels easy and enjoyable to use.
This e-bike is perfect for commuting, running errands, casual weekend rides, or even light touring. While it’s not designed for aggressive trails or high-speed road racing, it absolutely excels as a utility-first folding e-bike. Features like built-in lights, full fenders, a sturdy rear rack, and chain guard all serve a purpose and enhance practicality.
Room for Enhancement
feet, the compact frame may feel cramped over time. Additionally, the folding mechanism adds significant weight, bringing the total to 29kg. That’s a lot if you need to lift the bike regularly.
The display is another area with room for improvement. While it shows basic information like speed and battery level, it lacks the clarity and modern design of some newer e-bike models. There’s no smartphone app or advanced ride tracking—something that might deter tech-savvy users who want more connectivity.
FAQ Section
1. Can the RadExpand 5 handle off-road trails or rough terrain?
Absolutely, within reason. While it’s not a full-blown mountain e-bike, the fat tires offer solid grip and cushioning over gravel, sand, dirt paths, and even snow. The frame feels rugged, and the overall construction holds up well on bumpy rides. That said, for extreme mountain biking or steep, rocky ascents, you might want a more specialized model. The RadExpand 5 is ideal for casual off-road use and urban environments with mixed surfaces.
2. Is the RadExpand 5 suitable for tall or very short riders?
This bike is designed with a relatively compact frame and adjustable components, making it a great fit for many average-sized riders. However, taller individuals—particularly those over 6’2”—may find the riding posture a bit cramped, even with the seat and handlebars fully extended. Shorter riders, on the other hand, will likely find it more accessible than many standard-sized e-bikes.
3. How easy is it to fold and transport?
Folding the RadExpand 5 is straightforward after a few practice rounds. The hinges and locking mechanisms are secure, and the folded size is decent for storage in small apartments, RVs, or car trunks. The only issue is the weight. At nearly 29 kilograms, lifting or carrying it for long distances—especially up stairs—can be a real challenge. It’s foldable, yes, but not lightweight.
4. Does it come with lights and safety features for night riding?
Yes, and this is an area where the RadExpand 5 scores high. It comes equipped with integrated lights that make nighttime or early-morning rides safer. The fat tires and wide frame also give a sense of stability, which is reassuring in lower-visibility conditions.
5. How long does it take to charge, and how far can it go on one charge?
On a full charge, you can expect a range of up to 45 miles under optimal conditions. This includes moderate pedal assist, flat terrain, and light loads. Charging takes about four hours from empty to full, which is relatively quick for a bike in this class. If you’re commuting or running daily errands, it’s easy to top up overnight or during work hours.
6. Can you ride it like a regular bike without electric assist?
Yes, the bike can be pedaled without electric assist, thanks to its 7-speed gear system. However, given the bulk and weight, it’s noticeably more laborious than riding a standard bike. You’ll feel the extra effort, especially on inclines. The gears help, but the motor really earns its keep when it’s turned on.
7. What type of maintenance is required?
Like any e-bike, it benefits from regular checks. Keep the tires properly inflated, periodically inspect the brake system (which is hydraulic and generally low-maintenance), and monitor the battery’s health by charging it regularly and storing it in moderate temperatures. The folding mechanism also needs occasional tightening to stay secure over time.
Final Thoughts: Is the RadExpand 5 Worth It?
The RadExpand 5 strikes a compelling balance between utility, comfort, and rugged practicality. It doesn’t try to be flashy. Instead, it delivers on the basics—and does so with an extra layer of versatility thanks to its foldable design.
It excels in urban environments, where you might need to weave through traffic or store your bike in tight corners. But it’s also confident on backcountry roads or sandy coastal paths. The ride feels stable and well-supported, thanks to the thick tires and sturdy frame. While it’s certainly not featherweight, it’s durable and offers a more planted experience compared to flimsier foldable e-bikes.
The bike also includes small but thoughtful features that make a big difference: full fenders, integrated lights, a basic display, and a chain guard that keeps your pants clean on the commute. These details contribute to the “ready-to-ride” feel that’s often missing in more budget-focused options.
What About the Downsides?
There’s no denying that the RadExpand 5 is on the heavy side. If you live in a walk-up apartment or need to carry it frequently, this could be a deal-breaker. Unlike carbon-frame folding bikes, this one wasn’t designed with weight savings as a priority. However, if you’re mostly rolling it into elevators, garages, or vehicle trunks, this issue becomes more manageable.
Another minor shortcoming is the display and control interface. It’s serviceable but feels a bit outdated compared to sleeker screens found on some competitors. It provides the essential data—speed, battery level, and assist mode—but lacks polish and customizability. Rad Power might consider updating this in future iterations for a more refined experience.
And finally, taller riders may not find the perfect ergonomic fit. Although the handlebars and seatpost adjust, there’s a limit to how far you can stretch things before the geometry becomes awkward.
Room for Improvement & What’s Next
Looking ahead, we’d love to see Rad Power shave a few pounds off the RadExpand 5’s total weight. Lighter batteries or aluminum frame tweaks could help make it more accessible to a wider range of users.
An upgraded display and perhaps app connectivity would also bring it up to speed with 2025 tech trends. Many riders are now looking for GPS integration, ride stats, and firmware updates—all features that increasingly come standard on mid-range e-bikes.
Still, Rad Power has historically focused on delivering value over flashy features, and they’ve stayed true to that mission here.
Summary & Verdict
Throughout this review, we’ve taken a close look at the performance, features, and user experience of the RadExpand 5. This isn’t a luxury e-bike loaded with bells and whistles. It’s a workhorse. A rugged, capable, and feature-rich option for city dwellers, weekend adventurers, or anyone who needs a bike that folds but doesn’t fold on quality.
The RadExpand 5 delivers where it counts: battery life, handling, durability, and comfort. It’s not perfect—no e-bike is—but it nails the fundamentals with confidence. Whether you’re commuting, exploring, or simply looking for a more eco-friendly way to get around, this bike earns its place in the conversation.
Recommendation:
If you value reliability, sturdy design, and the flexibility of a foldable fat-tire e-bike, the RadExpand 5 is worth serious consideration. Just be ready to handle its weight, and don’t expect cutting-edge tech. But if your priorities are practicality, solid range, and rugged performance, this is a bike that delivers excellent bang for your buck.
