It was surprising clean which shocked me thought there would be a ton of dust and there wasn’t.
I bought this at the local auto parts store.

I’ll have to invest in some Thanks
Unless noise or the minor improvement in accuracy really matter to you, I see no real benefit to upgrading.
The H1 and H2 are so good and have been faultless for me, along with the firmware improvements that made them more reliable for data.
Thanks Chad! That was sort of what I expected but just wanted to make sure. I will hold out then!
How are you thinking of visualizing the fore/aft acceleration? I don’t think an actual pendulum will work well. I wonder if a digital accelerometer/microcontroller/LED display would react fast enough (and show up on camera nicely) to visualize this.
I think that capturing the accelerations (both fore/aft and side to side) visually like this on the bike and on the trainer will help understand what the bike/rider are actually doing inside and out.
I plan a quick test a real pendulum first. If it fails, and it may, another option may be a bubble level. A curved linear one or the dome style may work too (and possibly show deltas in both axes).
If those fail, I will look for other more technical options.
I’ve never heard a good explanation for why the bike oscillates, but I don’t think it’s too complicated. As soon as you stand up and separate your mass from the bike, there’s just a rhythmic push and pull generated by your upper body. You’re basically shuffling the bike fore and aft as it rolls along at a relatively constant speed. The bike is free to react and it takes almost nothing to move it.
It is a real thing that’s sorely missing from rigid trainers. Anyone who rides a floating roller knows this. The floating action is like the heartbeat of cycling, and when you take it away, the overall experience feels dead. When I read comments saying motion is irrelevant, I just have to disagree.
When a company like Saris puts so much effort into motion, while other companies like wahoo and tacx totally ignore it…well that’s confusing. I’m not saying Saris got it right with their MP1, but at least they’re trying. My personal rig is the E-motion with a floating fork, which is essentially a floating platform with controllable tilt. You don’t just sit there and passively pedal, you actually ride it, so yeah it just feels right.
When we pedal standing, we end up with the bike “floating” under us like you mention, because we aren’t restraining it with our bottom on the seat.
When one foot reaches the bottom of the strike, that puts a high force on that side of the bike. Left in addressed, this would cause the bike to fall to that side. But we naturally apply an opposing force, via the handlebars, with our body. We have to “overcompensate” for the foot force with a lean on the opposite side.
This all turns into a pendulum motion as we repeat this for each pedal stroke. There is also a subtle turn of the handlebars that leads to a snaking motion where the front wheel moves back and forth across the road. Most people don’t even realise they are doing it, but it happens.
You can see this really well by watching the slow motion parts of Pete in the recent sprinting video.
You’re talking about side to side motion, right? I’m talking about front to back.
But as long as we’re on the side to side topic, you’re leaving out an important element…leaning the bike into the pedal stroke is producing leverage, which maximizes the arm force you can put into cranking.
Also the video does illustrate the guy in blue is generating more fore/aft motion judging by his surging position over the bars. The guy in red is moving less. I’d say the guy in red spends too much time on a rigid trainer, and it shows.
The ship date on the MP1 keeps slipping. Clevertraining.com has it currently as “early December”, but it looks like this has slipped by now too. Saris must be fine tuning some things as the original ship date was early October.
Hopefully they are able to get things to the point that they can ship them out soon.
Not sure on the cause of the delays. I think Ray said last week that he got a shipping tag for one from Saris. So maybe they are working on a more defined release along with a review?
Kind of like a planned release with a defined embargo date. But that probably doesn’t apply here since it was already announced and shown at various demo sites.
One small hope I have is that they are adding adjustable springs to the design. Comments from Saris reps said it’s not adjustable. And if so, that’s just crazy to me.
There are a few people here and in the FB group that have open orders. I hope they show in the near future, so we can get more feedback on the design.
I’ve got one on order as well from Clevertraining. I was able to get an H3 at the time of the $639 deal, so will put a thru-axle equipped bike on the H3 and MP1 (once it ships). Will leave my QR equipped older road bike on Tacx Neo for now (not on a rocker).
Adjustable springs would be a great option. Back in the days of the KK Rock-n-Roll, I liked it quite a bit firmer than what a lot of people were doing.
This thing looks amazing, I just can’t get past the $1200 price tag.
There are quite a few options for far less money, and you can also go with the DIY route.
ROCKR Indoor Training: St. Louis, MO (USA)
VengaVelo SpeeDeck: Minnesota, USA

The Clevertraining 20% Black Friday week special applied to it. Keep an eye out for future specials.
Same here , on order from Clevertraining. Tacx Neo will be put on it once it shows.
I balked a bit at first but ended up buying one of the Saris units. ETA is early January.
The way I look at it is that these things wouldn’t sell well even at half the price, due to the price. So the manufacturers need to make their R&D money back somehow.
If it were just side to side rocking motion, I probably wouldn’t have pulled the trigger, but the front and back motion is tricky to replicate using off the shelf components since the rails are curved.
If the thing works the way it’s supposed to, it’ll significantly improve sweetspot workouts for me. When intervals get longer than 10 minutes, I find saddle pain to be just as limiting as leg burning.
