Mars 2.0 750W

The Heybike Mars 2.0 750W is a budget-friendly, heavy-duty evolution of Heybike's highly popular folding fat-tire platform. While folding e-bikes are historically built purely for compact portability, the Mars 2.0 throws out that playbook by cramming a high-torque motor, a dual-layer suspension setup, and massive off-road tires into a collapsible frame.

It is designed as an accessible, rugged companion for commuters, RV owners, and weekend adventurers who need a bike that can easily fold up to fit into a car trunk or closet, but still possesses the muscle to tackle steep hill climbs or loose dirt trails.

The Technical Snapshot

• Power & Acceleration: Driven by a punchy 750W nominal rear hub motor that peaks out at 1200W and delivers 80Nm of torque. This gives the bike aggressive, snappy off-the-line acceleration and plenty of low-end grunt for tackling steep inclines.
• Battery & Range: Features an external, removable 48V 12.5Ah (600Wh) battery mounted vertically behind the seat tube to keep the center of gravity balanced. It includes a built-in USB port to charge devices on the fly and yields a real-world range of 30 to 45 miles.
• Speed & App Customization: Functions natively as a Class 3-capable machine, reaching up to 28 mph on pedal assist or via the left-side thumb throttle. It features built-in Bluetooth connectivity to the Heybike smartphone app, allowing you to fine-tune throttle sensitivity and adjust individual PAS speed limits.
• Double-Layer Comfort Suspension: To smooth out rough pavement and gravel paths, it utilizes a dual-layer cushion system: a 65mm travel front suspension fork (featuring preload adjustment and mechanical lockout) paired with an integrated 45mm travel suspension seatpost under a plush comfort saddle.
• Brakes & Gearing: Stopped reliably by mechanical disc brakes clamped onto 180mm rotors front and back. The mechanical drivetrain is an entry-level 7-speed Shimano Tourney system configured with a 48T front chainring and a 14-28T rear cassette.
• The Pegboard Utility Rack: Features an overbuilt, heavy-duty integrated rear rack that handles up to 120 pounds on its own. The standout design element is its custom pegboard-style side panels, which allow you to easily bolt on custom DIY storage configurations, gear baskets, or pannier bags.
• Tires & Folding Geometry: Rolls on ultra-wide, puncture-resistant 20x4.0-inch fat tires that can be aired down for traction on sand, snow, or loose mud. Built on a 6061 aluminum frame with a low 15-inch standover height, it collapses via a mid-frame hinge in about 15 seconds. It scales in at 75 pounds and supports a 330-pound total payload capacity.
