Reader Story: Does Pedal Kickback Actually Happen?
This where I went to too, needs something measuring position and/or force at the cranks. Kickback in this experiment is inferred, not measured. But how would you measure it at the cranks? Position - it would be hard to differentiate between natural leg movement in the rider or other "noise" and actual kickback. Force, power meter? (well strain in the pedal or crankarm or chainring) - again, really hard to differentiate between rider input or other noise. If you just wanted to prove kickback exists, maybe fit a "dummy" chainring which free rotates around the crank axle, then you can just measure rotation, easy to spot it occurring then.

Opinion: Why Weight Doesn't Matter
The handling of an heavy ebike sucks a good chunk of fun out of it for me. Had two decked out ebikes, not for me. I never found more grip either, I have way more instances with rear wheel over taking me or getting kicked off line, once it was going, it was going. Probably more instances of losing front wheel too.

How to Accurately Calculate What Spring Rate You Need
Na, progressive frame you run less shock sag because you end up with more sag at the wheel. ie 25% shock sag on a 30%+ progression frame is more like 29% wheel sag.
