You might not immediately associate “adventure” with folding electric bikes, or perhaps folding e-bikes haven’t even crossed your mind. However, the robust and versatile RadExpand 5 Plus from Rad Power Bikes could very well change your perception. This Class 2 e-bike, boasting a top speed of 20mph and equipped with a throttle, is an upgraded iteration of the original RadExpand 5 launched in 2022. Featuring a suspension fork, sturdy 20” x 4” knobby tires, a durable construction, and ample accessory options for storage, this “Rad Bike” is engineered to transport you and your gear efficiently and joyfully across various terrains, from dirt paths to gentle singletracks. But how effectively does it deliver on this promise? Let’s delve into the details.
As someone who champions electric bikes for practical transportation and owns several myself, this was my first experience with a Rad Power bike. Initially, I anticipated being underwhelmed. My preference leans towards mid-drive motors over the rear-hub systems that Rad utilizes, and I harbored some skepticism regarding their budget-conscious components and battery technology. Frankly, my reservations lacked substantial basis; I was simply questioning the capabilities of a bike priced at half the cost of my larger, Bosch-powered e-bikes. However, I’m pleased to report that my experience was overwhelmingly positive and surprising in numerous aspects.
Effortless Unboxing and Setup
Rad Power Bikes operates predominantly as a direct-to-consumer brand, and their delivery and setup process is remarkably streamlined. The bike arrives securely packaged and virtually fully assembled. My task was limited to unfolding the bike, snipping a few zip ties, correctly positioning the handlebars in the stem, and tightening them. Within approximately ten minutes, I was ready to ride.

For those unfamiliar with bike assembly or apprehensive about receiving a bike in a box rather than purchasing from a store, Rad Power Bikes provides excellent support. The included instructions are clear, intuitive, and guide you through each step of the process. Once you’re ready to ride, the vibrant full-color display is easily readable, and the controls, including the throttle, are highly intuitive to operate.

This “rad bike” features a step-through frame that conveniently folds down to roughly 30”H x 25”W x 40”L. This compact size allows it to fit comfortably in the cargo area of most crossover vehicles, although its weight of around 74 pounds means you might need assistance when lifting it. This folding capability is a fantastic feature, making the bike ideal for RV travelers or anyone wanting to explore riding locations away from home. It is available in a single frame size, designed to accommodate riders between 4’10” and 5’10”. Despite being 6’2”, I found the bike comfortable to ride. However, significantly taller riders might encounter issues with powerful pedaling.
Range and Power Performance
The RadExpand 5 Plus is equipped with a substantial 720 Wh battery. It’s important to note that e-bike range is influenced by numerous variables, making it somewhat unpredictable. I’ve managed to achieve 68 miles on a single charge using power levels 1 and 2 (out of 5). Conversely, using only the throttle at maximum power, the range reduced to about 37 miles. Your actual mileage will vary depending on riding conditions and power usage.
Power is delivered via a 750-watt motor situated in the rear hub, generating 64 Nm of torque. Torque sensors are integrated to intelligently boost power when needed. I found the power output to be more than adequate, particularly on flat surfaces. When tackling steep inclines, the power delivery is somewhat less impressive, especially compared to the potent mid-drive motors found on contemporary and lighter e-mountain bikes. However, unless you frequently plan to ride up extremely steep fire roads, this “rad bike” should provide sufficient climbing power.
The battery is UL certified and incorporates Safe Shield technology for enhanced protection. Each battery cell is individually encased in a fire-resistant material, ensuring that if one cell overheats or ignites, it won’t cause a chain reaction throughout the entire battery pack. This is a reassuring safety feature, especially when charging the bike overnight.
Ride Quality and Practical Utility
The upright riding posture typical of step-through folding bikes might suggest a less-than-agile or even cumbersome ride. However, the RadExpand 5 Plus is surprisingly nimble and facilitates smooth, sweeping turns even at higher speeds. The large, wide tires contribute significantly to shock absorption, as does the front suspension fork. Nonetheless, a suspension seat post would further enhance ride comfort, as the upright riding position tends to concentrate bump impacts in the seat area. The hydraulic suspension fork, while offering a modest 50mm of travel, is a welcome addition.

The bike’s substantial weight and wide tires provide excellent stability, even on unpaved surfaces and at speed, inspiring confidence in most riding situations. While it’s advisable to avoid rocky and technical terrain, this “rad bike” handles smoothly on the type of dirt paths you’re most likely to encounter – well-maintained, graded dirt roads.
Braking performance is reliable, thanks to 180mm rotors paired with hydraulic brakes. Bringing the bike from 20mph to a complete stop is quick and controlled, with no issues noted.
For urban riding, this bike is a blast. A quick twist of the throttle gets you up to speed with traffic, bringing a smile to your face. I’ve equipped mine with a large cargo basket on the rear rack, capable of holding two grocery bags, camping gear for a night under the stars, fishing equipment, or even a few holiday hams – its utility is limited only by your imagination. The RadExpand 5 Plus boasts a substantial 315-pound payload capacity.
Final Verdict: A Rad E-Bike That Surprises
In conclusion, the RadExpand 5 Plus is simply the most enjoyable e-bike I’ve had the pleasure of riding. Seriously. It’s fast, agile, versatile, a joy to ride on both paved roads and dirt trails, and surprisingly capable of carrying a significant amount of cargo. Rad Power Bikes has clearly invested considerable thought into the design of this bike, and at a price of $1,900, it offers exceptional value and utility. My initial expectations were modest, and I’m happy to admit I was wrong. Rad Power Bikes has truly impressed me with this “rad bike”.
