RadRunner Max

The Rad Power Bikes RadRunner Max is the absolute peak of Rad’s compact utility lineup. It takes everything loved about the legacy "moped-style" runners and supercharges it into a high-tech, Class 3 heavy-hauler. Dropping the basic single-speed architecture of older models, the Max brings a highly responsive torque sensor, a true 28 mph top speed, and cutting-edge safety features—like a built-in rear traffic radar—that you would normally expect on a high-end commuter car, let alone a utility bike. It is wrapped in a distinct Deep Emerald Green frame and serves as Rad's ultimate car-replacement machine.

The Technical Snapshot

• Power & Performance: Driven by an optimized 750W rear hub motor delivering 90Nm of torque for effortless, snappy acceleration and dominant hill-climbing power under heavy loads.
• Smart Electronics & Sensors: Upgrades to a highly intuitive torque sensor utilizing Rad's RideLogic tech to match motor output directly to your pedaling force. It operates across Class 1, 2, or 3 settings to hit a fast 28 mph on pedal assist (and 20 mph via the half-twist throttle).
• Battery & Dual-Range Potential: Houses a semi-integrated, lockable 48V 14Ah (672Wh) Safe Shield Advanced Battery (UL 2271 certified) encapsulated in thermal potting resin to prevent fire risks. It achieves a base range of 19 to 61 miles, but features unique plug-and-play architecture to support a second battery extender, expanding your range to over 125 miles.
• Automotive-Grade Safety & Tech: Features an integrated rear-facing safety radar system that tracks vehicles approaching from up to 330 feet away, displaying their relative speed on your color LCD and automatically flashing your brake lights to alert the driver. It includes Apple Find My tracking, a security PIN code or Bluetooth/RFID key fob unlock, full fenders, a 450-lumen auto-sensing headlight, and integrated turn signals.
• Brakes, Wheels, & Suspension: Outfitted with premium hydraulic disc brakes paired with extra-thick 2.3mm rotors for massive stopping power and extended pad life. It rolls on low-gravity 20x3.5-inch all-terrain tires and absorbs road chatter via an 80mm travel front suspension fork.
• Utility & Cargo Capacity: Weighs 82 pounds but handles a massive 420-pound total payload capacity (with a 275-lb rider limit). The integrated rear cargo deck holds up to 120 pounds and works seamlessly with Rad's extensive catalog of passenger packages, center consoles, and delivery baskets.
