AMPX 2000W MTX High-Performance E-Bike Conversion Kit (48V-72V Rear Hub)

Insane 80 km/h Performance That Fits Your Current Frame

Most conversion systems that push past the 50 km/h mark require massive, custom motorcycle-width dropouts that ruin the look and handling of a standard bicycle frame. The AMPX 2000W MTX Kit shatters that barrier. Engineered explicitly around a universal 135mm rear dropout hub sizing, this monstrous direct-drive power block drops cleanly into conventional hardtail, downhill, or urban commuter rear triangles. Enjoy maintenance-free hub reliability, near-silent operation, and explosive linear acceleration.

⚡ Technical System Matrix

Why the AMPX 2000W Kit is the Ultimate Performance Upgrade

🚀 Massive Multi-Voltage Battery Versatility

The smart, heavy-duty 45A pure sinewave controller features flexible multi-voltage tracking. Whether you are running an agile, lightweight 48V downtube block or a custom high-voltage 72V triangle cell pack to max out your top-end speed at 80 km/h, this controller instantly adapts its low-voltage cutoffs and power profiles to match your cells.

🏁 Toughened MTX Double-Wall Rim Profile

High-velocity impacts require industrial-grade wheel architecture. Every single kit comes factory-laced with heavy-gauge spokes into a specialized MTX alloy double-wall rim. Boasting a wide 33mm internal rim track, it supports aggressive 2.30” to 2.40” all-terrain tires, absorbing punishing trail ruts, hidden rocks, and pavement drops without coming out of true.

🔌 Pure Sinewave Control Smoothness

Say goodbye to the loud, irritating motor hums common with cheap, square-wave controllers. The premium 45A AMPX brain uses pure sinewave power modulation. This yields smoother throttle engagement, drastically reduces motor noise, and minimizes power loss via heat dissipation for increased riding ranges.

🚫 Critical Integration & Battery Requirements

• 🔋 Battery Discharge Prerequisite: This high-amp system excludes the battery pack. Your chosen power source must be equipped with a high-performance Battery Management System (BMS) rated for a minimum of 45 Amps continuous discharge. Running low-amp commuter packs will trigger immediate system safety shutdowns.

• 📐 Drivetrain Constraints: The hub casing features a standard threaded layout built exclusively for screw-on freewheels. It is not compatible with modern cassette spline configurations or thru-axle frame arrangements.

• ⚖️ Legal Enforcement Notice: This high-output 2000W conversion kit is intended and sold strictly for private property tracking, closed-circuit racing, or designated off-road tracking use.
