What does this actually mean? As far as I am aware there is no fancy mechanicals/electronics in the trainer to "simulate inertia".

Sounds like they still put all other trainers at a deliberate disadvantage in the simulator, which is hardly a positive!

So basically they've taken the existing Pro and painted it yellow?

Simulate Inertia - When the slope changes BKool delays the onset of the resistance to simulate your inertia but gets it baldy wrong.
It even does this when the slope goes from up to down but use the same delaying algorithm which actually slows your acceleration.
However one almost cancels out the other in the long term and therefore the inertia simulation is a) wrong b) the sum of the wrongs cancel each other out so you may have well not done it in the first place.

Smart adjustments on slopes - When the Trainer runs out of its physical weight/slope/speed capability is starts calculating your speed.
I don't think it actually knows it has run out (as it cannot measure its torque) rather they have simply added a weight curve to tell the trainer when to start calculating speed. Again it doesn't do this too well.

To me neither are a real selling point in reality but is looks good on paper.

PS: Where is this being advertised as it does not appear to be in the on-line shop?

Found it in the Press Releases

In fact I lied there. On short slope it can miss the fact the up-slope has finished because I don't think the algorithm runs constantly, only when the slope changes and then it applies the delay over a set time and so does not look at the instantaneous condiitions.

I for one am thankful that the Spanish never tried to put a man on the moon with their dodgy programmers and mathematicians...

Perhaps they did ..............try!
But decided to keep it quiet on account of them 'missing a bit'.
Had no problem with re-entry though.

Geoff,
I read your post earlier about weight loss and riding. Chapeau to you!
Have you thought about doing sub 2w rides with any of the riding groups on zwift? I find them good for recovery rides or simply to get miles in the legs. There are sub 1.5w group rides too. There are often more than a 100 people riding and a lot of banter over dischord. Perhaps not surprisingly, whilst many will be newcomers to riding and so riding to fitness many are also recovering from significant injury or similar. I would highyly recommend the Zsun or Pack rides , if you interested.

1.5 watt/ 2 watt, is that enough power to turn the pedals?

Do they have a 6w/kg group or are all those guys out helping/racing Chris Froome.
No doubt a few of us Pro owners could easily start one though.

Blooming elitist bkool pro owners and their crazy Pro watts!

There are some 5w plus training rides but I don't go near them for obvious reasons.

AAAC, I would love to see you race in Zwift with a PM and pro. You are clearly the strongest ride here and would have a different kind of fun on Zwift.i know it won't happen.

For sure I wouldn't be seeing 5+ watts/kg to often if ever!

I like my little dream world still, it's all paid for and requires no real additional investment.
Plus I have enough BKool Pro spares to last for the foreseeable future.
Should I get to the point where a new trainer is required then Zwift may well beckon complete with power meter equipped turbo.

The other thing I'm well aware of is that my ability to sustain my current power levels will soon come to an end and the slow slope to a respectable proper older cyclist like Jim will beckon.
Good thing is I don't see that as a demotion, quite the opposite.
Once I'm retired in about 2026 and if I am still capable of cycling then it may well become an outdoor hobby again by which time 60% of road going vehicles will be electric ,autonomous and programmed to be respectable to cyclist by not only not aggravating them, giving them room but also programmed to give them a draft until the next vehicle is behind them ready to take over.

By that time BKool may have also sorted out their pesky SW and the VR will be so good we wont need to go outside.
The latter is not too far away but I wouldn't bet on the former.

PERFECT PLAN AND PERFECT LEGS, but also a day where bkool was friendly with watt. I'm sure I would have done best time no matter, but maybe bkool gave me a 30 sec present

PS: Can you do Stage 4 tonight or early tomorrow so we can at least get ahead of you to start with!

If not I may have to break out my Classic/Pro Hybrid again and get some real power slings going.

Hmmm... I think I like this... is my cycling model attractive? I have to go easy in the pub this Saturday as I'm Sportive cycling again on Sunday...

I have a plan Mr @AAAC 76C - this winter I'm going to try reassignment and become @Jim Brown 76C

PS - I have never ever been considered as proper. But i kinda like it...

Smart adjustments on slopes - When the Trainer runs out of its physical weight/slope/speed capability is starts calculating your speed.

My classic's resistance max's out at about 6% for me at the moment, due to registered weight. It used to go into blue speed numbers then get lower and lower speeds as the gradient increased from this point.

The last firmware update (18 months ago?) seemed to remove this adjustment. When ever I do sessions in bsim I get the wheel speed not a calculated speed on slopes above 6%. However on other software, like BRVR or RGT, I get a power related speed. I have tested this by uploading a BRVR session to bkool and re-running the session. I was much faster time and speed wise, but not greater in power. IIRC the avg pwr was less than 5w different.

I like the ego boost of bkool watts, but I'm realistic enough to realise, until the weight goes down, no matter what power I put out I'll still be slug slow

Jim, that's not may age it's when I was 16, 1976 C (September) intake
You would have to be 56C A (January) or B (April).

Or to celebrate when you left school, 53 C.

Yep, you can tell all your non-cycling workmates how your were knocking out 400 watts on your turbo last night and a Mini Cooper S only does 128 (KW).

He's done it already, 31:48

Looking at his HR he was in bed when he did it but averaged 5.1 W/kg
