Wouldn't it be something like Ft-LB Force per sec?

Hi, Rick here, I'm a USA Cycling coaching and bike fitter. A lot of clients ask questions I can usually answer but looking to experts here to help with those I cant. I just published a paper in a medical journal with my daughter who is a Doctor Physical Therapy to document why 1/2 of my clients...

My thoughts... Are we discussing only the physics of the bicycle or the physics of the bike AND rider? For this post, Power = Force on pedals X Velocity spinning. What Dr. Martin found was that as the crank arm gets shorter, you gain cadence (velocity) faster than you lose force. But if too...

That's Dr. Jim Martin's study (https://faculty.utah.edu/u0238089-JIM_MARTIN,_PhD/research/index.hml) 120mm, 145mm, 170mm, 195mm, 220mm crank lengths. 145mm produced most power.

Summary: How to calculate weight on pedals? For example, a bicycle pedal manufacturer might say that their pedals have a max rider weight of 120kg (264lbs). First off, since the rider is sitting on the saddle, I'm not sure how this would really impact max pedal weight? Going forward, these are...
