Wattbike Atom

Hey all. Just checking in on something. Been using my old (15+ yrs old ribble winter bike) on a kickr snap (5 yrs old) and generally been good to me.

However decided to upgrade as my wife has expressed an interest. (And would never fit on the Ribble). So we’ve got a Wattbike Atom.

All good. However just wanted to check.
On the old kickr with power smoothing on and in Erg the power line was very very consistent. And felt very consistent. (And I know it’s not everyone’s cup of tea but liked it)

On the Wattbike. In ERG mode. The power is very variable. And feels quite variable. Don’t get me wrong. It feels more realistic. But wondering if this is everyone’s experience?

I’ve attached 2 pics to show the difference in how the power looks. And it really does feel as different as the graph shows.

Interested in anyone’s experience? Just to make sure I’ve not got some settings wrong etc. Thanks


ERG mode hunting ( over and under shooting) is a known issue, was picked up by DCRainmaker in his incredibly thorough review last year.

To be fair, the Kickr is known to produce heavily smoothed graphs, with almost no variation. What is the smoothing interval on the wattbike?

Cheers for this.

Let’s hope they provide a firmware update. Not the end of the world. Lots to like. But when I need to increase to 300watts and it spikes at over 400. It’s a bit of a surprise!!

It settles a bit after a few seconds but is quite spiky!

Wouldn’t have a clue the smoothing interval?

@Rich_R Not sure about the Wattbike Atom but I have a Wahoo Kickr Core and don’t use power smoothing and my graphs look more like your 2nd graph. I don’t worry about the spikes - I just focus on doing the work. For me the spikes often happen when the ergometer adjusts the power and I get ahead of the prescribed cadence. I try to stick as close as possible to the target cadence through the power change to manage the spikes. I find that it is sometimes it is hard to do on efforts over FTP when I am fatigued.

@JSampson thanks.

It’s not a huge problem and the article shared earlier by DCRainmaker calls it out as an issue specific to the Wattbike.
It does settle as cadence settles but yes. When fatigued. Having to hit 100watts above target for a few seconds stings a little.
Still rule 5 right!!!

I’ve had my wattbike atom 1st gen for I think 3.5 years now.
Yep, it overshoots a lot. Try to be quick with your cadence changes, and try not to be changing your cadence as the unit is changing the power or it goes all over the place.
Yes, I too think of the massive power overshoots as being good for the sprint training.
You get used to it and can control it to a certain degree but difficult to eliminate. I still love my atom and use it anything from 2 to 6 days/week depending on the weather.

Exactly the same issues as you. But I still like my Wattbike. The Ribble hangs on a wall now…

Just ignore short term variations, of no consequence at all

Not quite that straightforward. They are noticeably different. And occasionally impossible to ignore. (Ie +100watts over the target, albeit briefly)

Briefly had a first gen early Wattbike and experienced exactly this. It made the bike unusable for me and I returned it during the initial free return period.

Still using 1st gen Wattbike with no issues
