RoadBikeReview's Take

Usually trainers and rollers are reserved for the winter months, only making appearances on rainy days. But CycleOps aims to help you ride and race into fitness all year round with new Hammer direct drive smart trainer.


Setup and teardown is easy, though lifting the Hammer requires some effort. Good thing it has a built-in handle.​

Indeed, smart trainers, virtual riding, and programmable intervals have some riders hammering away indoors even when the sun is out. Numbers driven training is at an all-time high, with output getting easier to interpret and smart trainers allowing you collect all the data you could want.

Hammer supplies a very sturdy platform for riding inside.​

Set up of the trainer is easy, two folding legs providing a sturdy base. (CycleOps claims the widest footprint on the market.) Unpack your cords, plug into a power source, and you're ready to ride. A small light indicates that Hammer is ready to pair with your device of choice. Multiple end caps are provided for both quick release and thru-axle combinations, making it easy to set up. It even comes with break blockers in the wheel tray.

Once in motion, the Hammer pedals smoothly, delivering the most "road like" feel that I've ever experienced on a trainer. This is attributable to a larger flywheel size, providing realistic spin up and resistance. Flywheel weight is 20 pounds, and nearly double in size of any smart direct drive trainer currently on market.

This time of year you need motivation.​

Pairing with your favorite virtual riding platform is easy, and most apps have help support that walks you through what can otherwise be a complicated pairing process. For building workouts and riding in ERG mode, CycleOps Hammer provides controlled resistance and power measurement. Unlike other electronically controlled trainers, Hammer records slight fluctuations in power during programed efforts.

Hammer has a maximum wattage of 2000 watts, so you can work on your sprints. And unlike other trainers, if you struggle or stop pedaling in the middle of an interval the Hammer lets up in resistance, allowing a rider to work back up to prescribed wattage. If you've experienced the wall effect that comes with a stopped interval on similar units, you know how cool this feature is.

Hammer can fit all types of thru axles, including Trek's ABP.​

In simulation mode the CycleOps Hammer rides smooth and clean, only adding resistance when encountering inclines on your virtual ride. You change gear just like you would riding outside, and the Hammer can simulate a maximum incline of 20%.

It's the little things that make me smile, like knowing who looked over your trainer and help assemble it.​

Bottom line, the CycleOps Hammer makes indoor training fun, and I'd recommend it to anyone looking to add more focus to their training, especially those who love virtual riding such as Zwift.
