In 2015 the Wahoo KICKR was the turbo trainer I opened my wallet for. Since then, I’ve been able to test most of the smart turbo trainers on the market. But over the last few years, competition Wahoo has faced have really upped their game. We’ve a new Wahoo KICKR Review to see if they are still top dog
Wahoo KICKR Review (Gen 2) | Zwift Gear Test – Kings New Handle
The Wahoo KICKR has always been in the upper reaches of the turbo trainer pantheon, but over the FIVE years since the original KICKR was released at EuroBike in 2012, the KICKR has grown a little long in the tooth. Yes, there was an update in 2015, which amounted to the inclusion of an extension to the power socket, but since then the hardware has remained unchanged.
The latest model has received a much more comprehensive update. The stand out features the update in this Wahoo KICKR Review:
- A new balanced handle
- Power and communication lights (so glad!)
- 15% reduction in volume
- Improved accuracy
- Improved ergonomic
- Improved resistance levels
- Improved responsiveness
I think it would be unreasonable to say that the update is a little, minor, as I’m certain that a lot of work has gone into the KICKR 2. But, comments like improved responsiveness are not the easiest thing to quantify, and so many of the changes feel like polishing work rather than major changes, or new features – handle notwithstanding!
So the main question is, have these updates been enough to keep the Wahoo KICKR from dropping down the turbo trainer rankings? After all, a new handle isn’t exactly a compelling feature! That said, it may be that Wahoo has played a very shrewd game, polishing their halo product sufficiently that the KICKR remains the turbo against which all other manufacturers get measured against without a significant draw on resources – let’s see!
Now I don’t tend to update previous reviews – as much due to time as anything. But my original Wahoo KICKR review was written right back at the very start of TitaniumGeek. Before I had my format set, and crucially before I had the experience of testing the majority of other trainers out there. So with that in mind, this has been written as an entirely fresh review!
Wahoo KICKR – Initial Impression
With most new product releases, headlines shout; “slimmer, sleeker, lighter!” This isn’t the case with the Wahoo KICKR. Which still weighs in at a hernia inducing 21.3kg. Now that is not such a significant weight as when the original Wahoo KICKR launched, and practically had the direct mount turbo trainer market to itself. Now the range of direct mount turbos is larger, but the weights are all similar: Tacx Neo, at 21.7kg, Elite Drivo, at 21kg, and Cycleops Hammer, 20.8kg. In spite of this similar weight, the Wahoo KICKR Gen 2 does feel heavier – likely due to it’s more compact size when compared to the other turbos
Wahoo has given the box a colour palette change and has a picture highlighting the new handle, to allow you to identify the newer units.
But what we want to know is – What’s in the box?
Wahoo KICKR Gen 2 Unboxing
Unlike some turbos, the Wahoo KICKR Gen 2 box doesn’t contain much, very little on the paperwork front, and very few parts of the unit is practically good to go when you open the box
We have a dual voltage transformer, both EU and UK plugged cables in the box. The charger is dual voltage meaning that this unit should be pretty good to go where ever you plug it in on the planet.
A steel turbo skewer, small tool of using with bikes that use disc brakes, and an adapter to use with different widths of rear chain stays
Neither the original nor the Wahoo KICKR Gen 2 have the ability to give cadence data… so Wahoo simply throw in the Wahoo RPM2 cadence sensor which is normally has a £30 RRP. I think this is a much better approach than building in cadence measurement to a turbo – the RPM2 is a dual channel sensor, i.e. Bluetooth/ANT+, so is going to work with Zwift on your laptop or iOS device. But is also a nice and discrete sensor in it’s down right that you’ll also be able to use with your bike outside. Only a subtle matter, but does increase the value of the package
Similarly, the Wahoo KICKR comes with an 11 speed SRAM/Shimano cassette (11-25) pre-installed. So you are quite literally ready to go when you get the unit unboxed and plugged in. It is worthwhile noting if you have a 10-speed bike, a spacer is included so you can mount a 10-speed cassette too
Some people will want to use their own cassette on the Wahoo KICKR Gen 2, so they are simulating their bike for training as much as possible on the turbo. However, for many people, they are happy to jump on the included cassette straight away. Overall, for being literally “plug and play” I think the inclusion of the cassette with the Wahoo KICKR Gen 2 is a good call. But if you prefer a different cassette, I can how it would be nicer to have a slightly lower cost!
As mentioned, there is relatively little in the KICKR box, so we’d better look at the device design!
Wahoo KICKR – Device Design
So I unboxed the KICKR down stairs, as there was better light in my kitchen. It also made a great opportunity to “test” out the redesigned handle on the Wahoo KICKR Gen 2 carrying it up the stairs. Suffice to say the new handle and position does make it MUCH easier to move the unit around, as the turbo stays level when you pick up, rather than being pulled to point down.
With the original KICKR people would ask, how robust is it, and I’d normally suggest if you hit the wall with it, you’ll more likely break the wall!! As the handle is now positioned to balance the weight of the KICKR, the unit is easier to handle when varying, so you’re also less likely to break your wall now! Win-win!
The handle on the new Wahoo KICKR is now horizontal to the ground, rather than at the same angle at the trainer. Now the Cycleops Hammer may a slick integrated design for a handle, but without a doubt, the handle on the new KICKR is the most comfortable.
The moulded plastic handle is screwed directly into the body of the KICKR and has a very grippy, grey, soft touch rubber coating.
I think it says quite a bit about the overt changes to the new KICKR that I feel compelled to focus on the handle in this way! Or just perhaps my dislike of the original KICKR handle.
IN ANY CASE, IT’S JUST A HANDLE!! MUST MOVE ON!
On the rear of the unit, we have a flexible power socket, which makes physically connecting to the Wahoo KICKR Gen 2 much easier than was the case with the original KICKR
On the original version, there was a small amount of kneeling down on the floor trying to find the cable, hanging down from the underside of the Wahoo frame.
Clearly, someone on the new KICKR engineering team went ergonomics mad on this version – but that isn’t a bad thing!! The both the Tacx Neo and the Flux could have done with a bit of ergonomic attention during design, the easy of moving these units…well isn’t!
At the back of the KICKR are two anodised blue buttons which release the legs, and which click back into place when you have positioned the legs in one of two positions – dictated by little cut outs on the metal chassis.
At the end of both adjustable legs, are chunky rubber adjustable feet which means that you should be able to get the KICKR to sit flat on most surfaces, and avoid it rocking about
The vast amount of the KICKR construction is metal; the welds are almost proudly standing out shouting “no plastic here!” giving the KICKR a very robust reassuring feeling when either moving it or setting it up
At the front, on the fixed, third leg of the KICKR is a series of markers, allowing you to unscrew a pin and change the height at which the KICKR cassette sits, meaning a turbo riser block is not needed.
On the back the turbo, just below the handle, Wahoo has added two new status lights.
The previous lack of any visually way of telling that your KICKR was actually powered on was one of my main

Wahoo KICKR – Zwift Gear Test
Once the unit is set up and attached to your bike, as ever, a firmware update is needed to be checked for.
This is done via the Wahoo Fitness app as preference
Selecting the sensor icon in the bottom left which will allow you to search for your trainer
Selecting the trainer brings up the settings associated with that trainer, it is also from here that you would perform the calibration spin down
Crucially in this app, it is here you will find out if there are any firmware updates pending
It is ALWAYS important to make sure that your system is running the latest available firmware, as you don’t know what bugs may have been resolved between yours and the current firmware. Wahoo is very good a bug squashing normally, so it pays to check periodically for new firmware
You will also be able to perform the calibration spin downs from this page
The actual process of the spin down takes about 45 secs, simply spin up to 36km/hr, and then let the unit coast. The advanced is pretty much the same apart from needing a 3 min warmup!
Wahoo KICKR Power Meter Tests
So the first part of my power meter testing, after having performed the
As ever the power graphs produced from the power meter on the test are compared with data from my longstanding and calibrated before each use PowerTap C1 and 4iiii Precision power meters. NB I’ve applied a 4-second smoothing to the data, which can be effective in highlighting subtle issues, and makes the graphs look, we smoother!
The first run of Jon’s Mix (Remember I said I had made a mistake) looked at little odd! I was getting a series of drop-outs along the workout, and my peaks were just a little off according to the comparison with the other two power meters.
Looking a little more closely, the drop outs from the Wahoo KICKR Gen 2, were not actually going to zero, all stopping at the same level of about 15 watts. Wasn’t improved with an advanced spin down either. We can see pretty mich the same if you take a look at a zoomed-in section of the graph, the drop outs are frankly odd and possibly regular.
The nature of drop outs, randomly and all to the same place does seem to fit with a software issue, rather than a hardware problem. Wahoo does kindly allow access to the beta firmware, and the issue improved considerably, but I don’t feel it is reasonable to perform tests on products using beta firmware, as the consumer doesn’t have access to that software necessarily, and the beta may not come out for some time. Thus I actually put the review of the Wahoo KICKR gen 2 on the back burner, waiting for the publically available update to land – which it did a few days ago.
Doing to the same test, but this time on the new firmware basically cured the entire problem. No drop outs and the power peaks are registering with all three power meters much more favourable. Score 1 for the firmware team!
Basically, from a power perspective, I’m VERY happy with the KICKR, now the new firmware is onboard. Using the trainer on Zwift, the response is exactly as you would expect for one of the top end trainers. You get a smooth progression as you move through the hills on Wattopia, and the resistance when doing a work out adapts in a snappy fashion
Powering up the hills, and then a down hill afterwards can trip up some trainers. With the KICKR, the change from high resistance to low follows the instructions coming from Zwift without an issue whether that is the deep undulations on the mountainsides
Or when spinning round through the volcano, this adaptability, is also important. In many ways it is the subtly of the gradient, and thus Wahoo KICKR resistance changes, which when pushing through the lava fields help to promote the realism in Zwift. On a turbo which has more jarring changes in resistance, this tends to pull you out of the simulation.
Wahoo KICKR “Gen 2” Sound Test Video
This is the first time I have been able to compare one smart turbo against it’s own previous generation. So here is a head to head sound test of the original Wahoo KICKR, against the new Wahoo KICKR
However, I would highlight that the nature of the sound recorded by the iPad here is much more intrusive than when riding the Cycleops Hammer, but the dB readings are quite in line with similar trainers with my power peaking at 769 watts, and delivering 59dB
Wahoo KICKR Review – Conclusion
Wahoo has a strong relationship with Zwift. As a result, the manufacturer has worked extensively over the years to refine and improve the Wahoo KICKR response to Zwift via firmware updates. However, that doesn’t mean that the Wahoo engineers focus solely on Zwift development, but also refining their product generally, hence the ergonomic changes we have seen. Wahoo has a very active firmware development team, and unlike other turbo, trainer companies do allow access to beta’s outside the company. As a result, they tend to be very responsive to issues that normally wouldn’t get a look in from other manufacturers. Coupled with the larger user base for testing means many issues are dealt with before a firmware officially see’s the light of day
A good example being that power drop outs were addressed within about one month of issues being highlighted, and rather than releasing a firmware that improved things slightly (which personally I find more annoying than fixing the problem) they dealt with the drop outs completely.
If you are on the fence about upgrading to a smart turbo trainer, I’d highly recommend the new Wahoo KICKR edition or Generation 2.
