Product Description The SUPER73-Z Miami SE is a compact, motorcycle-inspired electric bike designed for neighborhood rides, city cruising and everyday recreational use. Its low-profile aluminum frame, extended bench seat and wide tires create the recognizable SUPER73 appearance while keeping the bike accessible for a broad range of riders. A 500W nominal rear-hub motor delivers smooth electric assistance with a manufacturer-rated top speed of 20 mph in its standard Class 2 configuration. The Special Edition powertrain provides up to 30% more acceleration than the earlier SUPER73 system, offering more responsive starts and improved performance during normal urban riding. The bike is powered by a removable 480Wh, 48V 10Ah lithium-ion battery that complies with the UL 2271 battery standard. SUPER73 estimates a riding range of approximately 25–35 miles, depending on rider weight, terrain, speed, temperature, wind and other conditions. Charging takes approximately five hours. Unlike the standard Z Miami, the Special Edition model adds an adjustable front suspension fork, helping absorb vibration and smaller impacts from uneven pavement. The rear remains rigid, preserving the bike’s compact and uncomplicated design. Stopping performance comes from two-piston hydraulic disc brakes, which provide stronger and more consistent braking control than basic mechanical systems. Wide MAXXIS SuperSucker tires—approximately 4.5 inches at the front and 5 inches at the rear—offer a stable footprint and distinctive fat-tire styling. The single-speed drivetrain keeps operation simple, while the thumb throttle allows motor-powered riding without continuous pedaling where legally permitted. Integrated LED front and rear lights improve visibility during lower-light riding conditions.

The Special Edition powertrain offers quicker acceleration than the earlier system, particularly when starting from a stop. The bike is sold in a Class 2 configuration with a 20 mph top speed. Available riding functions and local operating rules can vary by location, so riders should follow applicable e-bike laws and wear appropriate protective equipment. Removable UL-Compliant Battery The 480Wh battery can be removed from the frame for charging or storage. Its 48V electrical system provides energy to the rear motor, lighting and connected electronic components. Actual riding distance may vary based on: Rider and cargo weight Average riding speed Terrain and incline Tire pressure Weather and temperature Wind resistance Frequency of stops and acceleration Battery condition and state of charge SUPER73 states that the 25-mile-plus estimate is based on Class 2 throttle-only operation at 20 mph under specified conditions. Adjustable Front Suspension The adjustable front fork helps soften impacts from cracks, uneven roads and rough pavement. This makes the SE version more comfortable on imperfect urban surfaces than the rigid-fork base model. The rear remains rigid, so the bike is best suited to paved roads, maintained paths and normal neighborhood riding rather than aggressive off-road use. Hydraulic Braking System Two-piston hydraulic disc brakes provide controlled braking with less lever effort than many mechanical systems. Hydraulic operation also supports consistent brake engagement during repeated stops. Brake pads, rotors and hydraulic components should be inspected and serviced according to the manufacturer’s recommended schedule. MAXXIS SuperSucker Tires The wide MAXXIS tires give the Z Miami SE a stable stance and help absorb smaller surface irregularities. The front tire is approximately 4.5 inches wide, while the rear is approximately 5 inches wide. Proper tire pressure is important for handling, range, comfort and tire life. Integrated Lighting The bike includes an LED headlight and LED taillight for improved visibility. A horn is not included as standard equipment. Recommended Applications The SUPER73-Z Miami SE is suitable for: Neighborhood exploration Urban and campus-style transportation Short-distance commuting Recreational street riding Paved bicycle paths where permitted Riders seeking a low seat height Users who prefer a compact motorcycle-inspired design What’s Included SUPER73-Z Miami SE electric bike 500W nominal rear-hub motor Removable 480Wh battery Battery charger Adjustable front suspension fork Hydraulic braking system Integrated LED headlight Integrated LED taillight Kickstand Basic assembly components Owner’s manual SUPER73 states that final assembly can generally be completed in approximately 15 minutes by following the owner’s manual.
