11:11 on 11/11: Poland's National Independence Day In 1914, Józef Piłsudski set out to reclaim independence for Poland that no longer existed on the map. After being imprisoned in 1917 for refusing to pledge allegiance to foreign powers, he was released on November 8, 1918, and returned to...

I'm a M.Sc. Process Engineer. In Poland, a student to graduate with M.Sc. writes a thesis, which is not published but put in a record. The funny thing about my graduation was this: I was expected to go to the Army as a conscript. If I were a graduated student, I would go to the Military Academy...

Let me show you Stomp how easily you can play with the numbers. Avinox M2S Boost. 1200 W mechanical power output. 150 Nm declared torque. ω = 8 rad/s or 76 rpm. Bosch. Let us assume the motor can produce 800 W max. Let us assume ω = 6.28 rad/s or 60 rpm. Torque = 127 Nm. Use ω=5.23 rad/s (50...

ebiketuningshop is a company that makes illegal e-bikes from street legal ones. As I said, no-one can deny the law of physics: τ = P/ω. If ω is unspecified, τ remains a marketing value of no meaning.

At what reference rotational speed? Paper is patient. Explaining: At the same rotational speed of the motor spindle, the torque can only increase if the mechanical output power increases.

clipless (226.7 ± 46.2 W) vs. flat (215.2 ± 41.8 W) ± clipless min 180.5 W, flat max 257 W. n = 4. Zwift. Did they ride out-of-saddle or sitting all the time?

On the latest ride, a friend who is very good at the bike tech touched the pulleys of my Deore XT derailleur of my big Vado. 'The pulleys are totally clogged by grime. Do something about it'. I also could notice myself the chain hadn't moved smoothly, especially through the tension pulley. So I...

Did Bosch say it increased the torque or the peak power?

Don't you think Stomp it might pertain to a competing cyclist but not to a weekend warrior? My feeling is all road cyclists wear SPD-SL and most gravel cyclists wear SPD MTB because they feel they belong...

Especially for @Chargeride :) One of the most popular Polish songs but in English :) He's really impressed me!

Gravel Off-Road + MOSTy A gravel group ride Weather "There is no bad weather only wrong clothes". The morning was frosty, the mid-day reached +7C and the late afternoon was dark and cold again. Each of us was perfectly aware what to wear. For instance, I rode the mid-day in my sailor's jacket...

Impractical with the drop handlebars.

Ouch. Still, "Bram Hoekstra" videos are exceptionally good.

SPD-SL (the road system) are the worst of them all. When I was a complete noob, I bought a pair of "arctic" shoes for winter riding. I could not understand them in the beginning! Once I read some articles, I bought the matching cleats and pedals. Winter shoes, indeed, haha! I almost fell from...

I own a pair, too. Unfortunately, the internal shape of that shoe does not agree with my foot, so I use them rarely. Now, on the third pair of Adidas Five Ten Freerider Pro. For winter, I wear Endura MT500 Burner Flat Waterproof (the best winter cycling boots I've ever owned!)
