Rad Expand 5 Plus

The Rad Power Bikes RadExpand 5 Plus is the heavy-duty, tech-forward premium sibling in Rad's folding fat-tire lineup. While the standard RadExpand keeps things basic and budget-friendly, the Plus model brings automotive-grade safety, top-shelf componentry, and an ultra-refined ride feel to a space-saving design.

By introducing a smooth front suspension fork, responsive hydraulic brakes, and a highly intuitive torque sensor, Rad transformed a simple utility folder into a premium, go-anywhere cruiser. It’s uniquely engineered for maximum stability, making it a great companion for RVers, campers, and city dwellers who need a machine that folds down small but rides big.

The Technical Snapshot

• Power & Performance: Driven by a custom-manufactured 750W geared rear hub motor delivering 64Nm of torque for snappy off-the-line acceleration and confident hill climbing.
• Battery & Safety: Outfitted with an external, lockable 48V 15Ah (720Wh) Safe Shield Advanced Battery (fully UL 2271 certified). It utilizes an advanced thermal-resistant potting resin around each individual cell to isolate and neutralize overheating risks, providing a reliable real-world range of 20 to 60 miles per charge.
• Drivetrain & Sensor: Elevates the ride via a fluid, lag-free torque sensor that matches motor output proportionally to your physical pedaling effort, eliminating the "surging" feel of older cadence setups. Speed is managed across 5 assist levels, a half-twist throttle, and a Shimano 7-speed drivetrain (14-32T freewheel).
• Brakes & Suspension: Equipped with premium Gemma hydraulic disc brakes clamped onto 180mm rotors with integrated motor-cutoff safety switches. The ride is majorly cushioned by an Exsho 50mm travel hydraulic front suspension fork featuring preload adjustment and a mechanical lockout.
• Handling & Sizing: Rolls on ultra-stable, high-volume 20x4.0-inch CST BFT puncture-resistant fat tires with reflective sidewalls. Its distinct high-rise BMX-style handlebars allow you to angle the cockpit closer or further away for exceptional steering control. Featuring an ultra-low 16.5-inch standover height, the geometry is optimized for an accessible rider fit between 4'10" and 5'10".
• Smart Tech & Utility: Tips the scales at 72.5 pounds and handles a 315-pound total payload capacity (including a frame-integrated 59-pound rear rack). The electronic layout features a vibrant Rad custom color LCD display with a USB-C device charging port, an auto-on 200-lumen headlight, full-coverage fenders, and an active rear brake light equipped with handlebar-controlled integrated turn signals.
