The Hammer Direct Drive Trainer redefines indoor training to create the ultimate riding experience. One that's versatile enough to handle the most intense interval sessions as it is the easiest of recovery rides. Simply put, the Hammer is the perfect addition to any athlete's toolbox.
This direct drive style bike trainer eliminates the tire-to-roller contact, and is capable of replicating any outdoor ride from conversational group rides to rolling hills to pain face inducing 20% grades. All of this is done with a smooth, road-like-feel thanks to a massive 20 lb. precision-balanced flywheel that replicates real world inertia better than anyone else. Paired with our innovative, rapid response electromagnetic resistance system and you've got a bike trainer that can cover large resistance changes in a blink of an eye at a whisper quiet 64 decibels. Plus, the Hammer's revolutionary axle compatibility gives you the freedom to choose any thru-axle or quick release bike now and for years to come. Simply add a cassette, pop off your rear wheel, connect to your favorite virtual training software and prepare to Hammer away.

I used the Hammer in conjunction with online riding programs, and could not be happier with the results. The road like feel and smooth, but noticeable resistance changes with the slightest elevation change on my computer made indoor training fun and effective. The noise level is quiet enough that it did not wake my kids sleeping in the room next to the trainer when I had to ride late in the evening. Resistance changes were very smooth and increased to the point I had to shift into granny gear on some extreme climbs. Setup is as easy as changing a cassette and replacing a skewer. I connected an ANT dongle and streamed the virtual ride to my TV for a more enjoyable ride. The trainer was very stable during sprints and folded up easily enough to fit in the closet when company visited and we needed the extra space. Using the Hammer definitely helped my outdoor riding this spring, and I can't wait to see what I can do after a full winter of riding with this machine!
Bottom LineYes, I would recommend this to a friend
The setup for this is only slightly more difficult than the wahoo kickr, but that is where my preference for the kickr ends. Side by side the noise difference between the kickr and hammer is nearly indistinguishable, but the interesting thing is that the hammer doesn't seem to vibrate the floor beneath it as much as the kickr. I could run this unit upstairs in the morning and (probably) not wake up anyone else in the house. The road feeling on the hammer is superior to the kickr as well. With the kickr if you stop pedaling during an interval it feels like you have to sprint in order to get the flywheel moving again. The hammer smoothly brings you back to the target wattage. And lastly (for this review) the hammer just feels more solid than the kickr. I'm not afraid to get out of the saddle and push some big watts while in the hammer. The kickr on the other hand feels a bit more flimsy. Really happy with this purchase.
