Ranger S 1000W

The Heybike Ranger S 1000W represents a massive, "hot-rod" evolution of Heybike's flagship folding fat-tire platform. While the original Ranger S relied on a 750W motor and a standard cadence sensor, this upgraded version steps into premium territory with a muscular 1000W nominal powertrain and a highly responsive torque sensor.

It effortlessly blends the portability of a folding, low step-through frame with the brute muscle of 4-inch fat tires and solid unibody mag wheels. It is engineered for riders who want a fast, heavy-hauling cruiser that can fold up to fit into a vehicle trunk or closet, yet packs enough instantaneous off-the-line torque to make the rear end noticeably squat when you mash the throttle.

The Technical Snapshot

• Power & Acceleration: Driven by a massive 1000W sustained rear hub motor that peaks at a wild 1800W and cranks out a hill-flattening 100Nm of torque for immediate acceleration.
• The Torque Sensor Upgrade: Replaces the jerky, delayed power delivery of older cadence systems with a fluid bottom-bracket torque sensor that actively mirrors your physical pedaling effort for an intuitive, lag-free ride.
• Speed & App Control: Operates out of the box as a high-speed Class 3 e-bike hitting 28 mph, but can be customized or fully unlocked via the Heybike smartphone app to reach top speeds of up to 32 mph on flat pavement (paired with a right-hand thumb throttle).
• Battery & Charging: Houses a removable, lockable 48V 14.5Ah (692Wh) UL-certified battery with a dedicated physical power switch. It achieves a maximum claimed range of 55 miles and includes a 4A fast charger to drastically reduce downtime.
• Brakes & Gearing: Stopped predictably by upgraded hydraulic disc brakes clamped onto 180mm rotors for reliable, light-touch stopping leverage. It manages physical pedaling through an entry-level 7-speed Shimano Tourney drivetrain.
• Unibody Mag Wheels: Rolls on high-volume, multi-surface 20x4.0-inch fat tires laced to ultra-sturdy, puncture-resistant alloy unibody mag wheels—completely eliminating the hassle of broken or loose wheel spokes under heavy cargo loads.
• Folding Geometry & Size: Built on a side-folding aluminum step-through frame that weighs 72 pounds (including the battery). Featuring an adjustable telescoping seat and handlebars, the single frame size comfortably accommodates riders from 4'11" to 6'2".
• Payload & Tech Amenities: Boasts a heavy-duty 400-pound maximum payload capacity. The tech suite comes completely fully loaded out of the box, featuring a front suspension fork, full-coverage fenders, a heavy-duty integrated rear rack, an electronic horn, an auto-on headlight, and integrated turn signals paired with an active rear brake light.
