Product Description

While your friends painstakingly negotiate with neighbors and significant others for limited hours of ear-assaulting wheel-mounted indoor trainer time or risk frost bite to round out the required ride time, you'll be dialed in and crushing out watts on your CycleOps Hammer Direct Drive Trainer. The direct drive design saves wheel and tire wear for the road and carries claims of being "quiet enough to ride in a library," which means you can get your intervals in and keep important relationships intact. The secret to the Hammer is a massive, 20-pound flywheel that utilizes electromagnetic resistance to deliver a smooth, realistic riding experience. While no indoor trainer can ever exactly mirror outdoor ride feel, the Hammer is about as close as you can get. It's able to simulate riding grades of up to 20% and is built to handle up to 2,000 watts, which means even the best pro riders won't be able to max the Hammer out. For the rest of us, it means that this trainer has the range of capability to knock out any workout intensity our coach adds to the schedule. Using PowerTap technology, the Hammer is PowerTuned to provide power readings with a +/-3% accuracy while internal cooling mechanisms ensure readings aren't impacted by heat so your data stays consistent across the duration of each ride. It transmits speed and power data to head units and devices via ANT+ FE-C and Bluetooth 4. 0 protocols, allowing you to read data real time and connect with third-party software and virtual training applications for an interactive training experience. The CycleOps Hammer Direct Drive Trainer includes a Shimano-splined freehub compatible with 8-11 speed cassettes. As an added touch, an integrated front wheel tray nestles neatly in the trainer for quick storage and easy access to the appropriate front wheel height when in use.

Good but not great

Good but not great
I bought this back in January. I wanted to give it enough time to give a fair review.The trainer is heavy, like really heavy. Its both heavy to lift and a solid piece of machinery. I would suggest a trainer mat under it to protect your floors.The Bad: This trainer has connection issues, Ant+ seems to drop off after 20-30 min ride and WILL NOT come back for that ride. (will connect next ride then disconnect to start the cycle over again) Can switch over to Bluetooth, but that will drop in and out during your ride, but is mostly pretty reliable. If you use Ant+ you will need a dongle and extension cable to place the Ant+ connection as close to the trainer as possible to prevent dropout.The Good: This trainer is good, its strong, it's sturdy, it's quiet, when it works, it works great. You can go full gas on this thing and it will take it and keep going... as long as the connection hold. I have done 3 hour rides on the trainer and as long as the connection holds, have had ZERO problems. In that aspect, its great!I think this is an amazing trainer, if you get one that doesn't have connection issues, your going to get an amazing trainer. If you're looking at this trainer, look at ALL the competition and prices prior to making your purchase, if this still seems like the best bet, go for it. But do ALL YOUR HOMEWORK first.

5.0 out of 5 stars Who says indoor training is fun? Cycle Ops Hammer does.
Reviewed in the United States on February 6, 2017
Verified Purchase
Quite impressed. It's my first direct drive smart trainer, so I really can't compare it to it's current competitors. I used Tacx Flow, Rollers, Kurt Kinetic Road Machine and a handful of others in the past 10 years. This Hammer just blows them all out of the water in terms of realistic road feel and overall performance. Trust me, if you despise training indoors (because you have to due to bad weather) and want to get a specific workout, this is a light at the end of the tunnel. Coupled with Zwift or any other training apps, the time flies because it's stimulating, engaging, and fun.

Set up is easy. Once the preferred cassette is installed, mount the bike on the drive train, plug it in, and set up your devices. The Hammer was recognized by my Garmin 520 and ANT+ dongle quickly. Power output accuracy is spot on as well and very close to what my Stages Power Meter is reading.

The ride: It's very smooth. I can't get over how much more efficient it feels compared to a standard drum-to-tire trainers. At higher watts during out of saddle bursts, the machine is stable and no rocking, tire slippage, smell of burning rubber, etc. Noise level is not bad either.

What's it like with Zwift? Well, it's pretty much built for it. Suffer every climb and feel every effort being put into it (Amazing) - Ride with the pack - Break PR's and achieve KOM glory - Train specifically for a race or simply build - Drop people poaching your workout - Get dropped - Enjoy the virtual world and simulated real world race courses - ALL with realism and in the comforts of your home while the roads outside are covered in ice.

Portability: It's heavy. I do like the handle and clever way to tow the front wheel base. Personally, I think the form factor works well for storage or taking it in a car for travel. Still possible to take it to races and use for warmups, just get a power plug adapter if you plan to use it as a smart trainer. If not, it's fine as a warm up machine as well without a power supply.

Cost vs function: It's expensive. I did not look at the price as if it's being compared to buying an actual road bike. Surely the price could easily get me an entry level read bike. But instead, I looked at it as an investment and as a supplement to my training.

5.0 out of 5 stars Best Value Smart Trainer on the Market
Reviewed in the United States on March 20, 2020
Verified Purchase
Out of the box in literally 60 seconds, 5 minutes to put a cassette on it (I'd never done it before), another minute or two and my bike is on it, updated the firmware with the Saris app in 5 minutes, connected to Zwift effortlessly. I just used the bluetooth on my iPhone. That comes to just 15ish minutes and I'm riding indoors.

This is the best value for money (I've decided) out of any smart trainer out there. The ONLY area this trainer is worse than more expensive smart trainers is noise. That's not to say it's loud. My chain and fan are noisier under 175 watts. Above that it slowly starts to become an audible whirring sound. And above 500 I'd say it's loud (not that you'll be doing that long). The flywheel is a bit loud but most other trainers are too. I've seen people put some grease inside the hub and it quiets down significantly so that's an easy fix if you don't like the ticking when free wheeling. I live in an apartment on the 3rd floor and no complaints yet!

The thing is a tank, super stable, just careful moving it once the bikes attached. It's very heavy.

Can't recommend it enough, no power dropouts, works like a dream. I'm surprised they're still selling it since it's so competitive with their revised models the H2 and H3. At literally half the price of those trainers you can't go wrong.

5.0 out of 5 stars great training aid for time budgeting triathlon training
Reviewed in the United States on May 12, 2018
Verified Purchase
I used a very crude wheel on drum trainer with viscous resistance 3 position resistance setting 25 years ago for triathlon training and hated it, with almost no use. Now resuming training for triathlon, and the Hammer is the mechanism to get training time and volume with any time slot I have available. I primarily run workouts of my own design based on percent FTP. This means no gear shifting and I can pull up any level workout I want anytime. I use Rouvy to control the Hammer. I find this form of training to be very useful. Setup is PC output to 42 inch older 1080 LCD, (2) 19 inch pedestal fans directed at me with my old competition bike (Softride powerwing) setup with aero bars and body position exactly like my Felt bike I race with. This saves wear and tear on the "new gear", essentially no chance of any trauma event, no weather limitations, no flats, pedal day or night, dial up stereo playlist, and very easy to jump off and T2 into running shoes and out the door for bike / run brick around neighborhood route. I use the Cycleops chainring power meter on Felt and the perceived effort / watts output between the trainer and real riding seems accurate. The watt output for "race pace" is known and is basis for workout design. I had read about this form of training prior to purchase, but I had to experience this over the last 6+ months and some 4k virtual miles to appreciate the value proposition it represents.

4.0 out of 5 stars More than good enough for casual biker
Reviewed in Germany on May 4, 2019
Verified Purchase
I'm casual biker and I have been riding MTB bike mainly in a city and bitten forest / field tracks on the suburbs for many years. Almost year ago I was looking for smart trainer in order to increase level of my performance and with little help of summer prices going down I ordered Hammer on Amazon some 9 months ago and started using it about 2 months later.
I have experienced several issues at the beginning:
1) dropping signal and loosing resistance after 10 or 15 minutes in all 3 apps I was using
2) uncomfortable feeling of imbalance when riding and difficulty to perfectly level my Hammer (place it evenly) on the floor
3) pain in my saddle after about 30 minutes of constant riding without any breaks in pedalling and without standing off the saddle.

Hopefully I have resolved issues no 1 and 2. Solution for the issue no 1 was buying USB 3.0 6 meters long extension cable and placing ANT+ dongle just next to the Hammer - no single signal drop since doing that, so I highly recommend this solution to anybody experiencing similar issue with the Cycleops Hammer!

It took just to get used to riding on the trainer and to better adjust legs supporting extensions in order to resolve issue no 2.

Unfortunately I have not resolved issue no 3 yet, despite ordering and using quality padded cycling shorts and reasonable quality saddle (Selle Royal Respiro Moderate - I'm using slightly higher stem than regular MTB and closer to 60 degrees than 45 position, so wider model of the saddle than my original MTB Scott which gave up couple of years ago but unfortunately wider saddle is not helping to reduce pain when riding constantly on the trainer). I just have done my research on other types of saddles recommended and just have ordered completely different type of saddle which is Brooks B17, hopefully it will finally give me opportunity to resolve issue no 3 as well.

I have also considered ordering or building DIY rocker plate which seems to be becoming popular recently. It should add some rocking movement to the still saddle position which could perhaps help to reduce pain due to changing pressure points etc. however after some research and consideration I have decided that commercially available products are not tailored well enough to Hammer's design (Cycleops guys have not released their plate yet) and attaching Hammer to rocking platform by just fabric belts / straps or similar things is not firmly enough. Similar thing with available DIY designs - Hammer seems to be much less rocking plate friendly designed than some other smart trainers. And on top of that all - I would feel not comfortable on the rocking trainer anyway, despite saddle pain, I do really feed good sitting kind of still and do not feel the need to mimic real life riding / technique nor doing any rapid accelerations with standing and rocking my bike etc.

As far as riding in Zwift or VirtueGo in regular mode is concerned (erg mode is not my thing), I can confirm that there is always few seconds delay between acceleration put on the pedals and acceleration registered and shown by the app and also between change of the elevation visible on the screen and resistance change felt on the pedals. It could be an issue for pros and ones with competitive approach but no issue whatsoever for casual riders like myself.

Overall I'm vary pleased with Hammer, giving 4 stars, not 5 due to necessity of buying and using USB extension cable (which was not that cheap). Highly recommended for casual and amateur indoor bikers and even for more serious cyclists too, perhaps just not for sprinters, real sport pros and highly competitive folks.
