The modern eBike PAS concept sure has come a long way compared to the old Mo-Ped technology.......with all of the torque, cadence sensors associated with either the spindle, chain ring, chain tension, rear cog, pedal force and even accelerometer sensors, everything can be monitored and adjusted on the fly. It's amazing how far gear cog assembly, cassette ratios, derailleur's and alike, have come.........eBike systems are damn near automatic transmissions...!
As for the rear suspension systems, I'm not sure whether it was or has been advanced through eBike or motorcycle technology. My gut tells me that off-road motorcycle intervention probably accelerated "mountain" bike systems......dual swingarm side mounted shock systems were the standard for on/off-road motorcycles for years. They were never practical for bicycles due to weight and obstruction. Then along came the single "Mono-Shock" systems in the 1970's, that were incorporated in the "motocross" bikes........it wasn't long before they started showing up on mountain bikes, at a very high cost. Front fork suspensions have been around forever on bicycles, either exposed springs, or telescopic gas or oil cartridge shocks. What has changed the most with that aspect is size, weight and adjustability.
Just like the combustible engine......the basic mechanical and operating principals/theories of both (cycles/automobiles) haven't really changed much over the past + 150yrs.......and we are now just starting to enjoy the advancements of batteries (electricity) implemented in both technologies.......thanks to the costs associated with each being reasonably attainable and massed produced today.........!
Note:
James.....I'm sure your are aware of the complications that arose when "disc" brakes were introduced to the bicycle..........even today, there are really only three popular brake systems that have their advantages and disadvantages, depending on application......cantilever center pull rim friction mounted, mechanical (wire tension activation) disc's and hydraulic (fluid pressure activation) disc's.........almost every other system is now obsolete.......lol
