Rad Power RadWagon 4 Review

Performance Comparison

Ride Quality

With its long wheelbase and heavy-duty frame, the RadWagon 4 delivers a smooth, damp, and predictable ride quality that prioritizes stability over nimbleness. Its low-step design makes mounting and dismounting easy, even when fully loaded, while the highly adjustable handlebar and seatpost comfortably accommodate a wide range of rider heights. Beyond its calm handling, the bike comes equipped with a suite of practical features that enhance the daily commuting experience. However, the proprietary 22-inch tire size and a bevy of recalls may have eroded consumer confidence; the issues seem to be sorted, and the value is undeniable.

With a substantial 76.2-pound weight and an elongated 78.7-inch frame, the RadWagon 4 prioritizes stability and composed cruising over sweeping turns over low-speed agility. While its length can make it feel somewhat bulky in tight spaces, the smaller 22-inch wheels and high-volume 3-inch tires lower the center of gravity and dampen road vibrations, creating a predictable, comfortable ride even when fully loaded. This steady handling is supported by a reliable Shimano Tourney 7-speed drivetrain and Tektro Aries mechanical disc brakes, which provide the necessary stopping power to manage the bike's significant mass and cargo capacity.

The RadWagon 4 combines accessibility with heavy-duty utility, featuring a low 23.6-inch standover height that fits riders from 5'1" to 6'4" thanks to a telescoping seatpost and adjustable stem. Its upright, cruiser-style geometry and ergonomic contact points prioritize comfort, while the sturdy frame handles a 350-pound total capacity—including 120 pounds on the rear rack. It's a highly adjustable, user-friendly workhorse that makes hauling heavy loads feel like a casual Sunday ride.

True to form, the RadWagon 4 is fully loaded with practical essentials like full fenders, integrated brake lights, a heavy-duty dual kickstand, and a handy USB charging port. Its most defining feature is the massive rear cargo rack and wooden platform, which serves as a blank canvas for Rad Power's extensive ecosystem of custom bolt-on accessories.

Range

With its 672Wh battery, the RadWagon 4 managed a respectable 26.38 miles at 17.3 mph in an all-throttle-range test. Since this “zero-effort” range included 1,450 feet of climbing, it represents the absolute minimum you can expect; you'll see significantly more distance if you're pedaling or sticking to flat pavement.

While the RadWagon 4 isn't the most efficient in its class, that thirsty 750W motor and heavy frame give the bike utility we wouldn't forego. The range remains perfectly practical for urban life, but the slow charging speed means you won't likely be making multiple long trips in the same day. Rad Power's “45+ mile” estimate might be a bit vague compared to competitors, but for standard around-town hauling, it's unlikely you'll ever find yourself stranded with a dead battery.

Power

With a 750W geared hub motor, the RadWagon 4 is not short on power. This Class 2 model accelerates quickly, holds speed well on gradual hills, and easily reaches its top throttle and pedal-assist speed of 20 mph. The 5 levels of pedal assistance provide a great range of support and top speeds to complement your pedaling effort and suit your preferences.

The RadWagon 4's 750W geared hub motor provides punchy off-the-line torque and confident climbing, maintaining adequate speed, even on hilly routes. The throttle is refreshingly independent of pedal-assist levels, allowing you to modulate all 20 mph of available speed simply by twisting your wrist—a feature that makes it easy to manage heavy loads without fiddling with settings.

The bike features five levels of cadence-based pedal assist that smoothly ramp up to a top speed of 20 mph. Since the motor responds to pedaling motion rather than rider effort, you get consistent, predictable power that kicks in within half a pedal stroke—with Level 5 offering the punchiest acceleration for conquering hills or heavy cargo.

Cargo Carrying

The RadWagon doesn't boast class-leading carrying capacity, but it's not far off and we expect it will suffice for most folks. Its total weight capacity is 350 pounds, whereas some other models can support 450 pounds or more. The rear rack supports up to 120 pounds and measures 28" long by 7.25" wide. Not the longest, but you can still fit two Yepp kid seats on it. Like most other cargo bike models, riders will likely want to invest in some of Rad Power's wide selection of accessories to maximize the cargo carry potential of this bike.

The large rear rack comes with a wooden top, and a plastic rear wheel cover should help to keep straps, shoelaces, and other things out of the spokes. It's fairly easy to strap items to the rack, but to haul kids or cargo, it's worth investing in some of the add-ons. Rad Power has one of the largest selections of aftermarket accessories, making it easy to deck the bike out for your exact needs. Running boards, kids' seats, pads, baskets, handlebars, and much more are available, and the front mount points make it easy to add a rack and basket below the handlebars. It is entirely possible to carry yourself, two children, and cargo at the front, as long as you stay below the bike's 350-pound total weight limit.

User Interface

The RadWagon 4 comes equipped with Rad Power's own LCD display and handlebar-mounted controls. The controls have decent ergonomics, their use is straightforward and intuitive, and the display clearly shows all of your relevant ride info at a glance. Charging the battery is also relatively standard, and it can be removed for security purposes or charging off the bike.

The RadWagon 4's interface is simple: a three-button thumb controller on the left manages power, PAS levels, and lights, while a right-side half-twist throttle provides an instant boost in any mode. From toggling the odometer to engaging “walk mode,” the controls are intuitive and easy to reach without shifting your grip.

The RadWagon 4 features a centered 2.25-inch LCD display that cleanly tracks speed, distance, battery levels (via five bars), and real-time motor wattage. With six intuitive data fields and an integrated 1A USB charging port for your devices, it keeps all your essential ride metrics visible at a glance.

The 672Wh battery pack is attached to the downtube of the frame. Using the included keys, you can lock the battery to the frame in either the on or off position, or unlock it for removal for security or charging purposes. The charging port is located on the side of the battery pack, hidden under a small rubber cover to keep water, dust, and debris out. The location of the plug isn't ideal, but you get the hang of it. Testing the 2-amp charger, we were able to fully charge the bike's battery in 7 hours.

Assembly

Assembling the RadWagon 4 is straightforward but a two-person, hefty task. Clear guides and tools are included, but given the bike's sheer size and weight, don't hesitate to outsource the job to a local bike shop if you'd rather skip the DIY workout.

At over 76 lbs, the RadWagon 4 arrives in a massive box and includes a dedicated toolkit, with a streamlined assembly process that takes about an hour. By following the manual and supplementary videos, you'll install the front wheel, handlebars, fenders, and the “deflopilator” spring with minimal headaches. It's a bit of a workout due to the weight, but the logical steps make the DIY setup very manageable.

Should You Buy the Rad Power RadWagon 4?

The RadWagon 4 isn't our favorite cargo bike, but its price is quite attractive. If you've been curious about using a cargo bike and wondering how many car trips it could save you, this may be your chance. Keep in mind that you'll need to add accessories to get the most out of the bike, but it's still an exceptional value, and you can now find aftermarket 22" tires.

What Other E-Bikes Should You Consider?

For a similar price and performance but without recall issues, check out the Lectric XPedition2. It offers very similar performance to the RadWagon 4, and you can buy it with a dual battery option to extend your range. If you want to take the plunge and be thrilled, the Aventon Abound LR is our favorite cargo bike, and it's far from the most expensive.
