Aluminum Alloy Frame

The ZX's aircraft-grade 6061-T6 aluminum alloy frame is lighter and more rigid than steel. Aluminum is also rust and corrosion resistant for worry-free riding in all conditions.

Multi-Class Ride Modes

The ZX features SUPER73’s new technologically advanced drive system, featuring multi-class ride modes. Each bike comes pre-programmed in the Class-2 riding mode, which allows for throttle operation and pedal assist riding up to 20mph. This enables the ZX owners to legally ride on most bike paths and public roads without a license, insurance or registration.

Next Generation PowerTrain

Powered by a state-of-the-art 615 watt-hour removable battery and a brand new motor capable of outputting up to 1350 watts of peak power, the ZX provides an estimated 30+ miles* of range at 20mph when using throttle only operation, and an estimated 50+ miles* of range using the ECO pedal assist mode.

All-New Seat

The newly designed ZX seat delivers greater comfort for longer rides and is arguably the most comfortable seat we have ever created. The extended length can accommodate small passengers (optional passenger pegs are available separately).

Better Ergonomics

With a 31” seat height, adjustable handlebars, and a 325 lb weight limit rating, the SUPER73-ZX is designed to comfortably accommodate riders between 5’1” to 6’8”.

Trooper Tires

Measuring 4" wide, the Trooper street tire features a hybrid micro tread designed for efficient rolling velocity. The tire was designed with a dense center tread pattern that extends tire life while an aggressive side tread provides a cornering grip. With good handling on the street, this retro-influenced tire is built to tackle the urban landscape with good wear over time.

Super73 App Ready
Super73's new generation of electric motorbikes comes with an electronics suite that pairs with iOS and Android devices through the Super73 mobile app.

Smart Display
A transflective monochromatic LCD display with Bluetooth connectivity allows riders to connect and control their bike with the Super73 app.

Turn-by-turn navigation
Riders will be able to discover new routes by dropping a pin or typing in their desired destination using the easy, turn-by-turn navigation available on the Super73 app. Directions are displayed on both the rider's mobile device and LCD Smart Display.

Over the air updates
The ZX is capable of receiving over-the-air updates to ensure the bikes have the latest firmware, operate at peak performance, and have the most up-to-date functionality.

Multi-Class Ride Modes
Each ZX bike comes programmed in the Class-2 ride mode, which allows for throttle operation and pedal-assist riding up to 20mph. This allows the Z-Series to be legally ridden on most bike paths without a license, insurance, or registration.

In addition, there are three other ride modes available. For areas where throttle-powered electric bicycles are not allowed, the Z-Series can be operated using pedal assist with the throttle deactivated in Class-1 and Class-3 modes. Class-1 allows for pedal-assist only operation up to 20mph, and Class-3 allows for up to 28mph. Additionally, an "Unlimited" mode enables up to 1350 watts of power under throttle and can reach speeds up to 28mph. This mode is exclusively for riding off public roads and on private property.

Optional features
An optional IoT module enables additional features such as remote anti-theft security and geolocation tracking.
