At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design.

Wahoo's Kickr Bike is certainly an impressive bit of kit, with one of the nicest ride feels of any indoor trainer I've tried. It's hugely configurable and incorporates Wahoo's angle-adjusting Climb tech into a static bike, which is impressive. It's not without its issues, though, some which will no doubt be ironed out with updates and some which definitely won't be, unless they send you new bits in the post.
The Kickr Bike comes in an intimidatingly large box, but it's surprisingly easy to put together. It's heavy, for sure, and really a job for two people, but the actual construction is simple. It's just a case of screwing the legs on and slotting in the bar and seat, plugging in the shifters and tightening everything up. It only took about 20 minutes.
Like all gym-style static bikes the Kickr is very adjustable. You can raise and lower the whole bike with a big lever on the seat tube, and the reach is adjustable at both the handlebar and the seat. I was a bit worried that the stem and seatpost adjustments – which are standard round tube profiles instead of chunky square-section beams – would feel a bit flimsy on a static bike, but I've had no issues with them at all.
The adjustability means you can get your reach right, but you can also experiment with moving your position forwards and backwards relative to the pedals. The seat and bar height are also independently adjustable, and the crank has a clever five-hole system that allows you to simply change your crank length from 165mm to 175mm in 2.5mm increments. Basically you can get it to exactly match your bike, and you can also try tweaks to your position that you can migrate to your real-world setup if they work for you.
If you've had a professional bike fit you can feed the numbers from that into the Wahoo app and it'll tell you where to set the sliders. The second option is to take a picture of your bike and match up various bits; given the wheelbase dimension, the app tries to work out your geometry and match that.
I tried it, with mixed results: the app got my saddle height spot on but the bike dimensions were a bit big – reach was too long, and saddle setback was too big.
The third way is to just enter your height and inseam, and what sort of position you're looking for, and the app will suggest some settings to fit you. I found the fit from that process to be generally better; the seat height was a bit too much – I have mine dropped about about 1cm due to historical back issues, and the app wouldn't know that – but other than that it was pretty much bang on in terms of feel.
Whereas the Tacx team already had a resistance unit that was capable of replicating gear changes and freewheeling downhills for their Neo Bike, Wahoo has a new unit sitting in this bike. It's a combination of a flywheel and motor, unlike the Neo which just uses the motor to emulate a flywheel.
So there's a 6kg flywheel and a pretty beefy-looking motor that Wahoo claims can offer 2,200W of resistance, not that I'm ever going to know. Like the Neo Bike, you can use the associated app to customise the gears to match your bike; all the road/gravel groupsets from SRAM, Shimano and Campagnolo are supported and you can use custom values if you want something else.
You can store multiple profiles in the app, which include both the bike's physical settings and its virtual gears. So if you have a road bike and a TT bike, you can have all the dimensions and gearing to hand. Which is nice. You can set the buttons on the levers to emulate your preferred setup too. Which is also nice.
Braking is supported, which isn't a big thing now but might well prove to be a couple of years down the line, when Zwift starts pitching you off the side of the Alpe if you're going too fast on the descent. Steering isn't, in the sense of the handlebar moving, but there are steering buttons on the inside of each shift lever. They don't actually work in Zwift as yet, though, and they're also directly where I place my thumb on the hoods, so I was pressing them all the time whether I meant to or not. That's not an issue when I'm not using them but it's bound to be when I eventually do.
The virtual gearing is very effective. Change up or down the block and there's an instant response from the bike as it clicks the resistance up and down. Looking at the power trace on Zwift you can see the jumps in power as the changes hit.
Like the Kickr direct drive trainer, the Kickr Bike has ERG smoothing as an option, which smooths out your power graph. I suggest you turn this off: I found that it made the power output from the bike pretty sticky, so that the bike would hold a certain power even when I backed off the pedals. Changing gear would usually wake it up. It works fine with ERG smoothing switched off, over both Bluetooth and ANT+, and the smoothing is pretty pointless anyway. It'd be better to just bin it, really. I can't really see the point of it.
Directly comparing the Kickr Bike to the Neo Bike, I'd say that the virtual gearing was as effective, and overall the bike has a slightly different feel. The Kickr feels a bit smoother, and the Neo feels a bit more responsive. Neither is better, really, but one might suit you over the other. Of the two, I preferred the Kickr.
Looking at my numbers from racing it's not like the Kickr was giving me extra watts or anything, but the overall feel made racing a bit easier. I think it's mostly to do with how the bike responds to harder efforts, and holds a higher power a bit more smoothly. When you're struggling up a rise, late into the race and well into the red, it just seems a bit easier to keep the pedals turning.
One thing I certainly didn't prefer is the placing of the gear readout. On the Neo Bike it's centre stage in front of you, and on the Kickr Bike it's tucked away down below the top tube. It's hard to see at the best of times, and if you're adding a sweat catcher – and I definitely am adding a sweat catcher to something I'm going to sweat all over that costs three grand – it's obscured, and you need to look round the sweat catcher to see what gear you're in. That needs a rethink.
The Neo bike (right pic) wins easily here: the display is great, and you also get a nice tray for your phone. You'll need some kind of mount for the Kickr. I just use a Garmin out-front mount and an old case with a 3D-printed garmin mount glued to the back, which works very well. There's a USB port under the stem so you can charge as you go.
The Kickr Bike does one thing that the other smart bikes don't do: it includes a tilt mechanism that physically simulates gradient. It can be set to automatically follow gradient if your preferred cycling app supports that, or it can be manually adjusted using the up/down buttons on top of the left-hand lever. You can switch between the two modes using a button on the side of the gear indicator box.
And it's very effective. It has a big range – from 20% to -15% – although your bike setup might curtail that a little bit at either end. The bike pivots about the seat tube, and the motor driving the motion is quiet and efficient. It certainly adds an extra dimension to the climbs and descents, and the whole experience is a bit more immersive as a result. It's also a physical cue to what's going on if you're not paying close attention to the screen.
I found that I liked it, and I was also glad of the fact that you can set the bike at about 8% incline after a race or hard interval session which gives you a nice sat-up position for cooling off.
I've used the Kickr Bike for about 1,500km of indoor riding, including a daft 500km charity ride that took 22 hours in total, and I have to say I'm impressed. It's a solid platform, the ride feel is excellent, the virtual gears are sufficiently good that you never really think about them, and the whole thing feels like a quality piece of kit.
The only real issue I've had during riding is that the central height mechanism – the one that adjusts the height of the bike as a whole – is prone to backing off slightly after a while, and when it does that it starts to creak. When it does it's a case of undoing the lever, giving it a bit of a jiggle and tightening everything up again, which isn't really something you can do mid-ride and is also something you (I) immediately forget to do as soon as I stop.
OK, let's have a look at some numbers shall we? Here's a plot of a race on Zwift, comparing the Kickr Bike (purple) with a set of Favero Assioma power pedals (blue). Normally I'd use my Garmin Vector 2 pedals but there's not enough of a gap between the crank and chain case on the Kickr Bike to fit them.
Anyway, it all looks pretty good. The pedals are reading slightly high compared to the bike, about 3% overall. There's no obvious discrepancy or dropouts over and above that. If we zoom in a bit to the first five minutes or so of the race:
You can see that the gap between the Kickr power trace and the Assioma pedals isn't necessarily exactly consistent, but they're tracking each other very well. At the start there's the usual ramp up to the start and a few short, hard efforts to make sure I'm keeping contact with the front group (don't worry, I lost them on the first proper climb). Then things ease off a bit before a harder section up the climb after the sprint and through the esses.
If I was looking at either power trace independently I'd be happy that it was a pretty accurate representation of what I was doing. In terms of absolute numbers I'd be more inclined to believe the Kickr; the pedals seem to be reading a bit high in my opinion, given what I know of my fitness and what other trainers have said my numbers are. Wahoo claims a +/- 1% accuracy, and since there's no calibration you're going to need it to be spot on.
Cadence-wise, it's a similar story: both plots are entirely believable, although again there's a minor discrepancy of about 1rpm between them. Which is correct? I've no idea, but unless you're aware enough of your cadence to know the difference between 90rpm and 91rpm it's not going to make a whole bunch of difference.
Now let's check out ERG mode and head over to a short structured session:
Again the pedal plot is on top of the bike, although interestingly they seem to drift apart a bit between the start of the session and the end; I'm not entirely sure what caused that in this instance as both bike and pedals were warmed up. If we look at three of the minute intervals:
We can see that the first is the one where the Kickr struggles most to maintain an accurate power, with the next one better and the last one the best. They were all ridden differently: the first interval is at my normal riding cadence (85rpm), the second spinning faster (100rpm) and the last one out of the saddle at low cadence (55rpm).
In the first interval the target power was 350W and the reported power is up to 50W either side of that. It's quite a discrepancy, and it's not ideal that the worst results are using the bike at normal riding cadences. By comparison, the fluctuation when standing was less than half of that on a higher target power, which is where I'd like it to be for every interval. Especially when I'm shelling out three grand.
The short sprints at the end (10 seconds at 630W, 790W and 950W) show that the Kickr is very responsive, but tends to overestimate the resistance needed for the interval, and then back off. Each of the intervals had a maximum effort of at least 50W over the requirement, with the middle interval topping out at 916W when the target was 790W. It's not unusual to see this ramp-up-then-back-off profile with smart trainers on ERG mode but I'd like to see Wahoo do some work with the algorithms here to make it less aggressive.
There's no getting away from the fact that at £3,000 the Kickr Bike is an expensive bit of kit. You can pay plenty more of course – SRM's static bike is €5,000 – but realistically this bike is mostly going to be competing with the Tacx Neo Bike Smart, the Stages SB20 and the new Wattbike Atom now it's been upgraded to an electromagnetic resistance unit. Aside from the fact that the Kickr includes the Climb mechanism, they're all pretty directly comparable: motor resistance, virtual gears, adjustable setup, gym bike quality.
Of those three, the only one I've actually tested is the Neo Bike, which is excellent; there's a new Wattbike coming in for review soon. All three are cheaper than the Kickr too: the Stages bike is a bit cheaper, and the other two are significantly cheaper. In the case of the Wattbike, over a grand cheaper. That's a pretty big saving.
Directly comparing the two bikes I've ridden up until this point – the Kickr and the Neo – I'd say that the ride experience of the Kickr is slightly better, and the user experience of the Neo edges it. So really, there's not a lot to choose between them in my opinion, and you certainly won't be disappointed with either. If the extra immersive dimension of the bike moving underneath you is important to you then the Kickr will be your choice. To be honest, it'll need to be pretty important to justify the difference in price between the two. If it was my money, right now I'd opt for the Neo; I'm looking forward to seeing what the new Atom has to offer.
