The RadRunner Max is one of the most versatile e-bikes on the market, packed with features that range from genuinely useful to techy and cool.
First, let’s talk about handling. This bike can be ridden by just about anyone, which is always worth highlighting. The low 17” step-over height is ideal for shorter riders or those with mobility concerns, and the 20” wheels help maintain a low center of gravity. With 3.5” wide tires, the bike feels impressively stable.
A payload capacity of over 420 lbs gives it serious utility for hauling gear, passengers, pets, or anything else you can dream up. And odds are, Rad has an accessory to help make it happen.
Comfort is a strong point, too. The ergonomic handlebar, 80mm suspension fork, padded saddle, soft grips, and upright posture all work together to provide a smooth and easy ride.
That said, one small drawback is the fixed-height stem. Rad says the bike fits riders up to 6’2”, and that holds up in terms of leg extension. But speaking as a 6’1” rider, I found the handlebar height a bit low for my taste. It’s usable, but I’d prefer a quill stem for more vertical adjustment.
The cockpit is straightforward and functional. The twist-grip shifter feels intuitive, the drivetrain shifts smoothly, and the gear range is well-suited for everything from flat roads to climbs.
The display is clean and easy to read, and it adds to the bike’s smart security features. You can unlock the bike via key fob or password, track it with Apple Find My, and even get alerts on the display about approaching vehicles thanks to the integrated radar system.
The radar readout takes it a step further by displaying the speed of oncoming traffic—a feature that enhances rider awareness and leads to few unwelcome surprises. I was impressed with how it worked – it caught a car approaching some three lanes of traffic away at one point on a ride.
When it comes to build quality, the frame feels tight, and the look is sharp with a paint job that deserves a shoutout. The metallic green is a real standout. Granted, there’s only one color option, which is a bit of a letdown, but at least the one they picked looks great.
As for the ride itself, it’s surprisingly pleasant. The bike weighs 82 lbs with the battery installed, but that heft isn’t really noticeable while riding. It rolls easily and maneuvers well. The 120-lb capacity rear rack and reinforced frame reduce flex and make cargo hauling feel secure.
A welcome feature is the dual-leg kickstand, which makes loading cargo easier and prevents the bike from tipping over—something that was missed on the RadRunner 3 Plus. Combined with Rad’s vast accessory catalog, the Runner Max can be dialed in to fit a wide range of use cases, and the ride is pleasant enough for a parent bringing along a toddler, or a grandparent enjoying retirement years.
