The way I compare bikes

I have several bikes, heart rate monitor and GPS. After the ride I load the data to computer.

The most interesting things to me are average speed and average heart rate. I make a diagram of these two parameters in a program that came with my Polar HRM, but you can use any program that can make diagrams.

This way you can compare bikes, tires, tire pressure, weather influence, different seasons. Just watch the difference between average speed and average heart rate on a diagram for that rides.

Now you can make your own conclusions about what influences your riding. I've found that major influence on my ridings makes the falling of the snow. Not those "heavy, unefficient, studded" tires, but the real snow on the road. I start using studded tires when there is yet no snow and can compare with "fast, efficient" slick tires. Well... There is no difference without snow. I compare Schwalbe Marathon Supremes Schwalbe Marathon Winters in this test. SM Winters are noisy, heavy, but no less fast. Oh... Many things you can compare...

So do it and write about your findings!

I recently bought a Bryton Rider 530 and it's pretty cool. It's my main bike for group rides. But on a couple of other bikes I completely removed the computers and it makes for a more enjoyable experience. I don't think about anything, I just ride. I'll coast and mess around on the bike or even take it off road if I want without worrying about my average speed dropping. I can pretty much gauge how far I've ridden. My 2018 New Years resolution was to stop keeping track of my mileage, average speed and all that and I stuck to it. I stopped being obsessed with numbers. I'm 50 years old and just happy I'm healthier and in better shape than 98% of millennials.

"The way I compare bikes?" I don't get it. Which exactly are the control variables? Please explain what the research can possible show...

When I'm on my Hercules 3-speed shopper i'm hitting 80-85 happy points.

On the stock Michelin tyres this can hit 90, as the back wheel slides a little under cornering. But with the Savage 2.5in slicks on, my average speed can reach 10mph.

Oh, general cycling discussion, where everyone is fitter than 98% of the population. No offense, but when your average speed is 10mph, of course tires won't make a bit of a difference!
Grumble, need more coffee. It adds 2mph to my avg.

When somebody invents a bike device that can measure how much fun we are having, that will change everything.

I've found ice to be a major influence- spike in HR, abrupt drop in speed.

No chart, though, & small sample size.

AHRate and ASpeed are observed. They are more or less proportional. You can choose scales for AHRate and ASpeed such that they go very close to each other. Now all you have to watch is the difference between them. Some rides AHRate is higher, some rides it's ASpeed that is higher. It becomes very clear which ride was better and you can analize why it was (if you were enough anal to make remarks after the ride).

On the same rout "better" means higher ASpeed while AHRate is the same or lower. But you can see the ride as a "better" even if the ASpeed is lower, but AHRate is out of proportion lower. It all is clear on a graphs.

While riding all I watch is a HR. I was foolish enough to ride in previous years near HRmax a lot. So I'm prone to it. Still like to bust myths though. There is a lot everywere.

Can you elaborate?

Too much fun will kill you! (I mean TOOOO much.)

Yep. In winter AHRate graph goes much higher than ASpeed.
