A heavy-duty electric conversion system engineered specifically for the EZ-3 USX HD, delivering strength, stability, and long-term reliability for high-load trike use.

Convert Your EZ-3 USX HD to Electric

The E-BikeKit™ EZ-3 USX HD Conversion Kit is built for riders who need more than a standard trike system can deliver. This kit is designed specifically for the EZ-3 USX HD frame and pairs a heavy-duty direct-drive hub motor with a 48V battery system.

Direct-drive motors are ideal for heavy-duty trikes because they have no internal gears or clutches, making them extremely durable under sustained loads. This system is well suited for larger riders, cargo use, and frequent riding where reliability matters most.

Who is this kit for? This system is designed for riders who prioritize strength, stability, and durability over lightweight or stealth. The EZ-3 USX HD platform supports higher total loads than standard trikes, and this conversion system is matched accordingly.

Optional battery mounting kit: When selected, this kit includes the battery mounting plate and all required hardware to securely mount the battery in the position shown in the product photos. This provides a clean installation and proper weight distribution for heavy-duty use.
