RadWagon 4 Assembly

The bike is delivered at your home, well-protected in a large cardboard box. Assembly is straightforward: just attach the handlebars, front wheel, and front mudguards, and you’re good to go!

The Radwagon 4 is delivered already partly assembled

Personally, I found the assembly process to be easy and quick, allowing me to hop on the saddle for my first ride in no time.

Here is my assembled RadWagon 4, personalized with some accessories (I’ll explain everything to you shortly below).

I’ve included the video of the RadWagon 4 assembly here just in case:

The RadWagon 4 features an aluminum frame with high-quality welds and large, stable 22-inch diameter wheels (resembling fatbike tires) that are 3 inches wide for a better stability. The telescopic seat can be adjusted in height to accommodate riders of various heights.

Why Choose the RadWagon 4?

During my recent urban getaway with the RadWagon 4, I rediscovered the pleasure of cycling through bustling city streets, all while having the capacity to carry far more than I had anticipated. Here, I’ll share my experience with you regarding this electric cargo bike.

Is the RadWagon 4’s Assistance Effective?

The Radwagon 4 motor: 750W with 5 assistance levels

The 250W hub motor is powerful and responsive. It provides efficient, effortless assistance at speeds of up to 15 mph.

Similar to the RadRunner 2 (refer to our review), the RadWagon 4 bike features a start-up aid that propels the bike forward at 3 miles per hour, activated via an accelerator handle, along with walking assistance ranging from 2.48 miles to 3.7 miles. Extremely handy for initiating movement when loaded or starting on an incline, even with a heavy load.

A very practical accelerator for starting when carrying a load

The 5 assistance modes offer excellent flexibility, enabling adjustment of assistance levels based on terrain and load.

During my test of the RadWagon 4, I particularly appreciated assistance mode 3, which provides a perfect balance between assistance and battery conservation, even during slightly more challenging climbs (although the bike certainly doesn’t do all the work: yes, you still have to pedal 😂!). It felt like having a subtle invisible boost that made pedaling effortless, without feeling the load too heavily.

A Powerful Battery for a Cargo Bike

The RadWagon 4 is equipped with a powerful 672 Wh, 48 V, 14 Ah Samsung 35 lithium-ion battery, providing a maximum range of 54 miles, which is more than sufficient for a cargo bike capable of carrying heavy loads. Naturally, if fully charged and using maximum assistance (Mode 5), you can expect a range of around 31 miles.

Large Load Capacity

The RadWagon 4 is a longtail cargo bike with a maximum load capacity of 394lb, including 116lb on the rear rack alone, making it ideal for transporting two children or numerous items such as rear bike racks, bags, or any other cargo. The frame is long and spacious, ensuring excellent comfort and stability.

Safety Features of the Rad Power Bikes RadWagon 4

In the dynamic and sometimes unpredictable world of urban cycling, safety is paramount, and the RadWagon 4 is no exception. This electric cargo bike is equipped with sturdy mechanical disc brakes that ensure reliable and consistent stopping power, even in challenging conditions.

Whether you’re descending a steep hill or need to stop suddenly in heavy traffic, you can rely on these brakes to provide the safety you require.

Additionally, the wide, grippy V-tire tires offer excellent traction on various road surfaces.

Not to mention the integrated lighting and reflective strips on the tires, enhancing your visibility and enabling you to clearly communicate your intentions to other road users.

The Advantage of the RadWagon 4: It Is Fully Customizable

Various accessories are available to personalize this cargo bike, such as cushioned boards, running boards, cargo bags, and awnings to shield passengers from rain and wind.

Around $436 worth of accessories to customize my RadWagon 4 cargo bike

Personally, I chose various accessories to make it the perfect cargo bike for transporting my children around town: a rearview mirror, a comfortable saddle, children’s seats, a metal frame for the rear area (referred to as a “Cabooze” by Rad Power Bikes) for the children to hold onto and stay safe, along with footrests for children.

Improved Stability and Excellent Grip

The RadWagon 4 is equipped with large wheels, a trademark feature of Rad Power Bikes. These wheels offer improved stability and excellent grip. Additionally, the wheels feature reflective strips for enhanced visibility, and an integrated rear brake light that is activated as soon as the brakes are applied.

Another advantage of this bike is its very low center of gravity, enabling greater maneuverability.

There is still plenty of room left for a 2nd child.

Comfortable and Easy to Use

The RadWagon electric cargo bike’s low frame facilitates easy step-over, a feature not present in all the cargo bikes we tested. The seating position is comfortable, although the saddle is somewhat firm. Moreover, the bike is user-friendly, thanks to its LCD screen which enables adjustment of electric assistance and provides battery status information.

My Test of the RadWagon 4 in Urban and Rural Settings

I opted for the RadWagon 4 in white, for a sleek and timeless appearance reminiscent of Tesla vehicles 🙂 During my urban test rides, I was pleasantly surprised by the attention the bike garnered; it’s clear that the bike captivates and piques curiosity.

I reached 18.6 miles per hour downhill: everything is OK! 🙂

Although compact, the bike offers ample space: I am 70″ tall and find the driver’s area spacious; it doesn’t feel cramped at all. The rear seats are also large enough to comfortably accommodate two children.

The 22-inch wheels provide excellent maneuverability, facilitating navigation through busy streets. The custom 3-inch tires, designed by V-tire, enhance the bike’s aesthetics while providing excellent grip and cushioning.

The mudguards come standard: a positive feature!

One of the features I particularly enjoyed during my test was how easy it was to adjust the bike for riders of different heights. Whether tall or short, the RadWagon 4 accommodates you comfortably, thanks to its telescopic seat post and tool-less adjustable handlebars.
