The relief from summer's sweltering heat comes at the expense of less hours of sunlight during the day. Eventually temperatures fall out of what we consider our comfort zone and we must face the very real truth of having to ride indoors. Wahoo's KICKR Power Trainer is designed to make riding indoors more enjoyable and serve purpose rather than just grunting away with a puddle of sweat on the basement floor. Wahoo is the official trainer supplier for Team Sky so they are well versed in bringing high-quality training products to the sport's best. The redesigned Wahoo adds more bike axle options, KICKR CLIMB compatibility, and new LED operation lights. Everything else remains making this trainer the smartest, quietest, most accurate road-feel experience you can have indoors.
The KICKR is a powerful, accurate, and responsive trainer. You will enjoy power measurement accuracy within +/- 2% and fast communication between the trainer and whatever virtual training app you're using. When your pixelated avatar is grinding through rollers, the transitions between descents, flats, and climbs are smooth, and the max measurable watts and simulated grade are 2,000 and 20%, respectively. These limits border on farce, but they mean your training sessions have virtually no ceiling unless you're riding a simulation of Flanders on a motorized e-bike. Indoor training is never ideal, but the KICKR's optimized algorithm helps bridge the seasonal cycling divide by making riding inside feel that much more like riding outside. Pairing the new KICKR with KICKR CLIMB will allow you to experience physical ascents and descents while riding along with virtual courses and performing structured workouts allowing you to get the most out of your indoor sessions.
The trainer's firmware with an enhanced power algorithm continuously reads and adjusts the massive electromagnetic brake. If this isn't your first Wahoo rodeo, then you're probably familiar with the brand's updateable design ethos; the change to the KICKR's power measurement design brings it more in line with this attitude, and it means that the KICKR is an investment rather than just a temporary stop-gap until ANT+ and Bluetooth are replaced by the next hot thing.
The KICKR's ease of updating may also be why Wahoo claims it's compatible with more training apps than any other smart trainer. No matter how many new tech startups decide they want to get in on the virtual training market, the KICKR will always be able to gobble up some firmware and leave you basking in the postprandial glow of a screen displaying your preferred app. It also broadcasts via ANT+ and Bluetooth signals simultaneously, and it can communicate with multiple devices through either protocol, so the only real limit to your choice of connections is the number of available power outlets.
The KICKR's reliance on external power, functional features, and prohibitive weight (the flywheel alone weighs 25lb) mean you probably won't be using it outside, so Wahoo also revisited the drive belt design in order to address the original KICKR's tendency to produce an obnoxious, droning whine. The fact that this whine seems to max-out while spinning at interval intensity only adds grating insult to the injury of indoor suffering, so we're pleased to note that the belt's redesign and re-tensioning drops the unit's claimed noise output from around 67 to 61 decibels and lowers the high-frequency pitch by 90%. There are quieter trainers, but the KICKR is the quietest model equipped with a flywheel. Flywheels increase that all-important road feel to help us stay motivated during long, winter wattfests, and the quieter operation ensures that, by the time we come out of hibernation for race season, we haven't alienated our neighbors and loved ones with months of mechanical cacophony. The old saying that "if you're still married, then you didn't train hard enough" doesn't necessarily apply anymore.
With a claimed weight of 47lb, the robust, stable body is largely unchanged—though Wahoo did find space for a few key updates to address common themes in customer feedback. The first and most obvious is the repositioned handle, which now makes for a more centered load while carrying it with one hand. The KICKR is still no lightweight, but the new handle design lets you carry the trainer in one hand and a rear wheel-free bike in the other—though navigating doorways may still be an issue. Navigating different wheel sizes isn't, though, as the blue support arm adjusts to reposition the cassette accordingly. There's also no need for a riser, though some of us in the Competitive office do prefer one in order to protect floors from tire scuffs.
The unit's final updates include purely aesthetic details like a pair of LEDs—red for ANT+ and blue for Bluetooth—that blink while establishing a connection to a device and shine steadily to indicate transmission. Again, this feature doesn't change how the thing works, but lights are cool, and we like seeing them on our tech toys. Wahoo also relocated the power port from its hiding place beneath the unit to a more readily accessible location. The new KICKR now accommodates 12x142 and 12x148mm thru-axles in Shimano/SRAM compatibility and allows for better clearance for disc and flat mount brakes.

- Q & A
Bought 1 then another
Bought 1 easy setup, daughter took it off to college so I bought another. which I have just set up since daughter loved it so much she took it to school... It is quiet... Hopefully, it will last a while, right now it seems pretty close to perfect... So much better than my computrainers...

I've owned 4 indoor trainers and this thing is hands-down worth every penny. Indoor training is not fun, but this machine with a combination of Zwift changed my winter training. Easy set-up. It's super quite. I can swap bikes easily. The bluetooth connects fast. I did over 1,900 miles, 100 hours, and 190,207 feet of vertical (electronic) climbing this past winter and this machine took it like a beast. I would 100% recommend this product to anyone looking for a indoor trainer.
Fun and easy!

The wahoo kickr is a great trainer. Virtually silent and rides very smoothly. Easy connection with online training programs. It makes indoor training more entertaining and is quickly set up. Very heavy but has a conveniently placed handle for moving around.

There are plenty of detailed reviews out there already so I won't repeat those (how it's relatively quiet, the weight of the flywheel, etc.). This is heavy so I recommend you find a spot where you can leave it. Save your old friction-style trainer for hauling to races. Fortunately the handle is well centered for when you do need to pick up and move a few feet. The physical setup is straightforward, especially since there is no assembly. What takes time is learning the software and data set up. It's not rocket science, but it's not obvious either when you have so many different devices and data being connected. You will have multiple apps on phone and/or computer (e.g. Zwift for training software, Zwift Companion app for in-training functions, plus 1 or 2 Wahoo apps that you may use from time to time). You will also have quite a few devices talking to each other. In a typical setup, that may include your phone or PC that runs the training software, your Kickr, and all your usual ANT+ devices (HR, power, and bike computer like Garmin Edge or Wahoo Bolt). You need an ANT+ dongle on your PC to get your ANT+ devices (HR, bike power meter) to connect. The best configuration I've found so far, once I got a dongle, is to connect my bike's own power meter as the source of power data, rather than the Kickr's built-in power data. That way you are recording power using the same power meter you are using on the road for consistency. When set up that way, the Kickr is ERG function is capable of controlling resistance to achieve the exact power target set by the training software.
Best Revision Yet!
- Familiarity: I've used it several times
The 2018 KICKR is the best revision so far. Is it quiet, as in silent. SILENT. The only noise is my noisy chain. The unit is solid, beefy and built like a tank. Road feel is much improved over earlier models and the resistance response is incredible. You can't go wrong with this KICKR! Wahoo really listened to their customers on this one. Get yourself one of these babies!
I have a Specialized Roubaix with a 10 speed cassette. Can I install one on this.
Is there a way to make the Kickr Campagnolo friendly? I read that the Campagnolo freehub adapter is not compatible with the newer Kickr trainers.
I would like to know the answer to this question also. I have two bikes with Campy.
Wahoo does not have a Campagnolo freehub for this trainer but they recommend using the included Shimano 11s cassette. The cog spacing is the same as Campagnolo so it will work with your 11 speed drivetrain although shifting may not be quite as good.
What size cassette comes with this trainer? 11-23? 11-25?
The cassette is a Shimano 105 11-28.
