SUPER73 Controller Upgrade by Handlworks

A third party component of the Super73 eBike system designed to improve the stock bike performance by taking over the operations of the bike. This controller removes the need to use the Super73 app.

The HANDLWORKS plug-and-play upgrade kit is designed for easy installation on Super73 ebikes.

The kit includes a controller with harness and display, seamlessly integrating with your stock vehicle.

The pre-flashed controller comes with a base tune providing a substantial performance boost of 2500W, resulting in approximately a 30% acceleration increase and a 10% top speed increase, as demonstrated by tests.

Please note: Installation of this aftermarket controller will void the bike warranty from Super73 and Ben Buckler Boards. 

HANDLWORKS plans to release firmware versions to support various upgrade tracks such as different voltage and power, ensuring adaptability as users enhance their vehicles, with the updates conveniently flashable to the BAC system.

HANDLWORKS is founded by former engineers and product professionals with extensive eBike and tech industry experience, HandlWorks goes beyond OEM standards, aiming to maximize the potential of eBike ownership. They invite enthusiasts to join them in pushing the limits of electric mobility.
