SUPER73-M1D SE Electric Bike – High-Performance 52V Fat Tire Urban Cruiser (A-Series)

The New Wave: Sized Intelligently for Daily Utility The SUPER73-M1D SE is built on the brand’s highly anticipated A-Series platform, completely re-engineered from the ground up with an ultra-rigid chassis and heavy-duty thru-axle architecture. Designed to solve the awkward, overly stretched riding position of traditional moto-style e-bikes, the M1D delivers an optimized 30-inch seat height. This mid-profile sweet spot allows a massive range of riders to comfortably swing a leg over, confidently plant a foot at red lights, and effortlessly weave through tight city streets.

Massive Torque & Extended Modular Range Under the hood, the SE trim pulls zero punches. Driven by a punchy 750W nominal motor paired with a snappy 52V electronics system, it delivers immediate throttle response and robust uphill climbing torque. Tucked beneath the flip-up bench seat is an internal lockable storage compartment holding a large 780Wh primary battery, with dedicated structural room to add a second modular battery (sold separately). Keep it single for a quick daily sprint, or dual-load it to instantly double your range for long-distance urban exploration.

Premium Special Edition Hardware The Special Edition designation guarantees heavy-duty, uncompromised components. To isolate you from jarring pavement, tracks, and potholes, the M1D SE boasts an adjustable front suspension fork for an incredibly smooth, controlled front end. Braking is immediate and reliable thanks to high-performance 4-piston hydraulic disc brakes, giving you elite stopping power with minimal lever force. The look is completed by premium, oversized Maxxis SuperSucker street fat tires (4.5″ front, 5″ rear) that provide a low-slung stance and unmatched cornering grip on wet or dry asphalt.
