Is there any advice that smoothing your pedal profile the way that Watt Bike suggest will make help you produce more power. Sorry if this has already been discussed but I did a search can could find anything. Apart from them saying it?

I also couldn't find any example pro Watt Bike graphs online?

I can't post any links but my understanding is that the whole pedalling in circles thing had been pretty much debunked.

The people that go that go the fastest are the ones that press the hardest at the front of the stroke. As long as you're not weighting the pedal at the back of the stroke and actually resisting the upward movement then I don't think it matters.

Only what I've read, not professing to have any specific knowledge of the issue myself.

Thank you. This is what my son was claiming too. It would be interesting to see some actual research.

There are some poor assumptions in there.....

Which one of them, or both?

I thought they were both flawed really.

Obviously the harder you push down on the pedals, the faster you'll go, but I think Wattbike reckon that when they stick a pro rider on their machines, they'll invariably produce a force diagram like the one that they tell us we should be aiming for.

I guess you need power and efficiency to go fast for a sustained period.

Our gym has a watt bike. I have a very cheap, not smart turbo trainer in a rickety shed.

Not having done looked at Watt bikes much, are they a good alternative to a turbo trainer?

Yes, showing my ignorance again!

Through experience, the wattbike numbers align well with my power meter outdoors. My dumb trainer is actually a pretty poor representation ... I can't hold anywhere near the same numbers on my TT (fairly sure due to the significant lack of inertia). Inertia on a wattbike is good.

The main drawback of using a wattbike would be not adapting to the position of your own bike. However, as I can be so much more time efficient by using them at the gym next to work during lunch breaks etc, the drawbacks are worth it for me. I just have to ensure I get as much time outdoors on the TT to work on my aero position as possible.

I probably will look at getting a top end smart trainer soonish so that I can have the best of both worlds.

It's the convenience that appeals to me. The gym is 5 minutes from home and is open 24 hours.

Space is becoming an issue as my son has just bought a bike so the turbo has had to be moved out of the shed until funds will permit a larger shed.

Sounds like the watt bike will suit my training alongside weekly rides out on the road
