This feature-packed utility bike delivers power, handling, and style in spades. It’s great for riders who want more than just a jack-of-all-trades. The RadRunner Max is what happens when you take a versatile utility platform and supercharge it—with a beefed-up motor and a slew of upgrades you’d expect from the premium option over its more
Strong motor performance. The RadRunner Max delivers plenty of pep and matching control, making hills feel easy and acceleration smooth.
Packed with safety features. From radar detection and hydraulic brakes to potted batteries and integrated lighting, the bike enhances your feeling of safety on the road.
Robust security options. Apple Find My integration, password protection, Bluetooth unlock detection, and a key fob offer multiple layers of theft deterrence.
Highly versatile. With a high payload capacity and powerful motor, this short-tail cargo bike is ready to carry passengers, gear, or both.
Customization and range potential. A broad accessory ecosystem lets you tailor the setup, and the rare ability to add a second battery means you can double your range.
Comfort-focused design. Wide, cushy tires, a suspension fork, and an upright riding position help soak up bumps and keep long rides comfortable.
Limited adjustability for taller riders. While leg extension is great, the handlebar height may feel low for riders 5’11” and up.
Minimal options for the price. At over $2k, the single color choice (while stunning) and included 2A charger feel a bit underwhelming (with no higher output charger offered).

Check out my in-depth RadRunner Max review from Rad Power Bikes, testing its speed, 420-lb payload, and innovative radar tech for commuting and cargo. I explore pros, cons, and features to see if it’s worth your investment.
The 750W rear hub motor pumps out 90 Nm of torque, making quick work of steep hills and heavy loads. A torque sensor delivers natural, quiet pedal assist across five levels, so whether you’re climbing or cruising, it feels effortless. With a twist throttle and up to 28 mph in Class 3 mode, with plenty of grunt to handle the job.
Rad claims a 19–60+ mile range per charge on the RadRunner MAX. For longer trips, the optional Range Extender battery tucks under the rear rack, boosting range to over 120 miles.
The integrated rear radar scans 100 meters back, showing a real-time meter on the full-color display to track approaching cars, while the taillight flashes to alert drivers. Add in 450lumen (low beam)/750 lumen (high beam) headlights, turn signals, and hydraulic disc brakes, and you’ve got a setup that keeps you visible and safer in busy traffic.
With a 420-lb payload and a 120-lb rear rack, the Max hauls groceries, gear, or a passenger with ease, paired with a comfy saddle and 80mm suspension fork for a smooth ride. Over 330 accessory options—think baskets, seats, or panniers—let you tweak it for your specific needs. See Latest Price
