Spend less time performing maintenance and more time enjoying the fresh air on the Alibi C Step-Through. It features our puncture-proof Nimbus Airless tires and an anti-rust chain, so upkeep is sure to be all but eliminated. And when you combine that with a relaxed geometry, high-rise handlebars, a suspension seatpost, and a step-through frame design that makes getting on and off the bike an effortless breeze, you get a bike that'll have you riding longer, more comfortably, and worry-free.
  • The hard-working & sturdy A1 Premium Aluminum frame is light and durable, and it also features rack and fender mounts features for easy portage and dry riding in wet conditions. You'll also find that it's engineered with our Fitness Geometry, meaning that you’ll go fast with maximum efficiency, but without the discomfort of an aggressive ride position. After all, the more comfortable you are, the longer you’ll ride.
  • The Alibi’s anti-rust chain keeps rolling smoothly, even after a couple of confrontations with the elements, so you can spend more time riding and less time fixing.
  • Featuring a puncture-proof core and an incredible level of traction, our Nimbus Airless tires provide traditional ride characteristics, without the hassle of ever changing a tube.
We control every aspect of our frame materials, and we’ve optimized our A1 Premium Aluminum frames for the best possible balance of ride characteristics. This means that our proprietary aluminum tubing blends high performance, light weight, and high value to create frames that are light enough for little legs, strong enough for rambunctious kids, and corrosion-resistant for parents that don't want to worry about replacing a bike just because it was left outside for a few weeks. And with our kids' bikes, you'll find that this material allows us to create an ultra-low standover, so the range of fit is extended and getting on and off the bike is a breeze.
By controlling everything from the raw material to extrusion, butting, swaging, and heat treatment of the tubes, we’ve optimized our A1 Premium Aluminum frames for the best balance of ride characteristics. Our proprietary aluminum tubing blends high performance, light weight, and high value to create frames that are light, strong, and corrosion-resistant.
Our long and thorough experience working with aluminum has allowed us to design aero shaped aluminum tubes that don't compromise on stiffness or responsiveness. Utilizing hydroform technology, coupled with the already excellent performance and weight benefits of our A1 Aluminum construction, we’ve been able to shape key tube shapes like seat tubes, down tubes, and seatstays to provide an extra performance edge.
