Wahoo KICKR Bike: ERG Power Smoothing // Firmware Update 1.4.0


Today’s video is from here in the DCR cave in Amsterdam, and it’s all about the Kickr bike You may recall my earlier videos on the Kickr bike where I rode through the llama lab test and in ERG mode The bike reported smooth power. So it was reporting the setpoint in ERG so for example The 200 watt steady-state just reported 200 watts not actually what I was doing on the pedals. 250 flatlined and my over-unders were very very squared off. A recent firmware update has been released for the Kickr bike version 1.4.0 is out I perform the update and a second Lama Lab Test here in the DCR cave a Quick overview of the changelog here from Wahoo for firmware at 1.4.0 and it’s dot point number 1 We’re looking at today, which is firmware support added for enabling or disabling ugh mode power smoothing They’ve also added firmware support for sending odometer data for remote diagnostics and some bug fixes for tilt calibration But it’s dot point number one We’ll be diving into today. Onto the update process and once connected to the Kickr bike via the Wahoo fitness app It’ll prompt here for the update. It will pull down their firmware perform the update and away we go a very similar process to that of all other Wahoo, products such as the Kickr, the Core and Everything else. Once complete. We now have the toggle switch there for mode power smoothing so we can toggle that off or back on. Today we’ll be turning it off for my tests And it’s worth noting the ERG mode power smoothing option is only a visual change for power reporting, the on bike on pedal experience Doesn’t change Ok cranking out some watts here on Titan’s Grove as the warmup It’s a really great course Titans Grove with the up and down hill simulations Really gets the legs warmed up for the Lama Lab Tests and the trainer and its components warmed up too. You can see there’s a few red sections before we get the legs ticking over into ERG mode and Into ERG mode here on desert flats and you can see on the bottom there. It’s not a flat-line smooth ERG mode So what we have is real power being reported up at the top there You see it bouncing around plus or minus 10 watts depending on how smooth I am on the pedals But it’s not locked into that artificial 200 watts and here into the overs and unders They’re not squared off either So for me, I’d much rather have the power reporting of what I’m doing, rather than that ERG mode smooth enabled With the Lama Lab Test now complete with the new firmware Let’s jump over here to the DCR Analyzer tool to see how the bike stacks up against the Assioma DUOs that were on the bike at the same time So standard Lama lab test here Which we should be all familiar with, using the Titans Grove course as the warm-up for the first 10 minutes so this is SIM mode so not a test of the ERG mode but Does give us an indication of how accurate the bike is up against another set of Assiomas. So, 270w versus 270w Titans Grove all looking pretty good there and Then into what we need to have a look at today, which is the ERG mode performance Jumping in here to the steady state and the sprints and all looking as expected It’s not flatlining from the bike which was what was happening previously with ERG mode. Moving on now We’re getting more real power from the bike You can see there the Jags up and down and the average is looking pretty close to the pedals So all looking good there into the sprint now this does break out into SIM mode but a good indication of how things perform and it’s pretty close there on to the 22sec over and under which is just Here as part of the Lama Lab Test and we can see there the power on the pedals and the power coming from the bike Reports exactly what I’m doing on the pedal. It’s not smooth. Not an artificial number and flat line So that’s more realistic power reporting with ERG mode smoothing turned off. Accuracy wise within one watt there, so no problems at all with the accuracy and the final component of the Lama Lab Test is the Flywheel speed test. On a smart like the flywheel is a little different in the way it performs. It’s more of an inertial Calculation test because it’s a single speed. There’s no real gear. So it’s a virtual gearing test It gets a little complicated with these bikes. Now what we have here is a slow flywheel speed test at 225w looking good Medium flywheel speed test or mid gearing and then a high gearing. So the 53/11 simulated there the experience in the pedals does change a little bit but the accuracy is still pretty good across the board there So all good. And finally for good measure just to see how this bike does stack up against Ray’s Assiomas just riding along (just riding along) 232w vs 234w All looking pretty good there power wise and the visual summary of that is right here with the mean max power Across the board there. So a little bit of difference for about two seconds right there [at the start] Other than that one for one across the board for the whole hour. They’re looking good So there we are ERG mode power smoothing is now optional on the Kickr bike. If you want to turn it on. That’s fine The power reporting out of this thing is pretty accurate But if you want that jagged line with exactly what you’re doing, which is what we saw on the pedals as well there’s an option there for you do flip that off and Ride on so there we are If you own a Kickr bike or looking at getting one, you’ll get one probably with the new firmware on it anyway. So good stuff from Wahoo keep those updates rolling. All right.

  1. I think Wahoo did a great job with the design of that bike, all except for the power cables, They should have found a way to route them through the base and out the tip of one of the legs

  2. Hey Shane, did you have anything like that on the Kickr too?

    my two Rotor 2INpower both report up to 20 Watts more then the Kickr itself, for example while riding Sufferfest? Has that something to do with the smothing?

  3. My KICKR Bike is on 1.4.0, but there is no ERG Power Smoothing option in the app as shown in the video (the Android app is up-to-date). Keep getting the feeling that the KICKR Bike is more of beta than a release product.

  4. A great, clear explanation of the changes as always Shane. Nice to see Wahoo keeping on top of bug fixes and updates across the range too.👍
