UTCustom Super Mounts (pair) - Black Anodized Clamp - Our Super Mounts get your mirrors out where they are the most useful. Our custom clamp allows the mounting bar to be positioned anywhere along the handlebar and adjust the angle. Works especially well with the larger tires found on our Catrike Annihilators and KMX K90 models.

Schlumpf 34T/68 High Speed Drive w/155mm Cranks - The Schlumpf High Speed Drive is our favorite piece of cycling engineering. This planetary gear setup will give you higher high gears and lower low gears. If you have a trike with a 20in rear wheel the HSD will give you back the high end you are missing.

EcoSpeed Electric Kit for KMX - The KMX EcoSpeed Mid-Drive will change your riding experience forever. Not only can you ride faster but longer than ever before at great speeds. Fly to and from work at no cost, take long rides with ease, and mostly enjoy the time spent on your EcoSpeed trike. Batteries not included.

Avid BB7 Rear Disc Brake Kit with Locking Brake Lever - Do you want a usable rear brake and not just something to keep the trike from rolling away? This kit adds a functional brake lever so you have total control. The lever features a locking pin so it doubles as a parking brake. We recommend combining this kit with our double-pull lever for the front brakes.

UTCustom Mesh Seat Upgrade for KMX - *Made to Order* This seat includes our aluminum seat frame, Utah Trikes Max Airflo Seat mesh, adjustable seat stays, velogenesis clamps, and frame attachment hardware for all 2012 and later KMX adult steel-frame models. Check out pictures of our custom K90 for more details.
