How Alien Flier Zip Line Trolleys Came To Be

After playing with an inexpensive plastic zip line ride at a friend's house, my daughters asked me to build them one. A close inspection of the toy left me concerned about their safety. With no seat, poor construction and a plastic handle, clearly falling prevention was one of the design improvement we had in mind.

We began designing and building them a safe, fast and fun backyard zip line trolley system that did not require a PhD to install or use. Our zip line trolley needed to incorporate premium materials, practical safety features and be cost effective to buy and install for regular everyday people interested in home zip lines and backyard adventure.

After several prototypes, each successive one faster and simpler to use, the Alien Flier AF-Xtreme made its first run.

Zip Line Safety - Zip Line Fun

With an integrated braking system and a ground level entry system the AF-Xtreme zip line kit offers homeowners, kids and kids-at-heart a safer home zip line experience, without compromising speed.. Our design philosophy means you can enjoy your backyard zip line with confidence.

With Alien Flier, once you have properly installed your cable system, you are ready to go! No crazy launch towers to build, feeble ladder contraptions or scary tire bumpers stops needed. You simply sit down at ground level in a comfortable, safe and durable seat and the zip trolley is towed into position.

When ready, gravity will take you on the zip ride of your life, a ride which you can end anytime you choose with a simple lever activated trolley brake located right above the anti-spin zip trolley handle. No other home zip line kit is safer, easier to use or more fun that an Alien Flier AF-Xtreme!
