How would these two compare

A 40 lb hybrid bike with tubeless tires added running Bionx (the more powerful one 350 I think it is)

A 22 lb road bike normal tires running Bionx (again the 350 or whatever it is)


The reason I ask is I have a 40 lb hybrid and plan to buy a road bike in the area of 22 lbs. I would love to make the hybrid a tubeless Bionx hardcore commuter, maybe even give it to my dad and we could go on rides together (me on the road bike). BUT, is there a lot of juice and speed wasted on that extra 20 ish lbs the Bionx is lugging around with the hybrid vs the road bike? (I weigh about 180 lbs)

My guess is no because the weight of a person varies greatly, but I wanted to ask

When you add all the weight and power of a typical e-bike system to a regular bike, (in addition to the weight of a typical rider, which already dwarfs the weight of a 20 to 40 pound unpowered bike) you will find that the weight of the base bike doesn't matter that much. The things that limit your speed are mostly aerodynamics and the fact that typical e-bike motors are designed to produce optimum power and efficiency around 20mph or less. (but running higher voltage will increase the motor's speed and power without changing its torque output, and a recent post says this is possible with BionX.)

I suspect any tubeless system that works in rough mountainbike usage will work equally well for an e-bike.
