Why there are no (to my knowledge) electric bikes with 700c tires? All the ones I’ve seen use fat tires, what is the reason behind that? Cc @nostupidquestions@lemmy.world

    I mean my mountain bikes run at a reccomended 50-80PSI, my road bike 60-120

    I can also get up to about 40mph downhill on both (which should be a good indicator of rolling resistance/air resistance as it takes out the pedaling part), so that leads me to believe (given the rolling resistance info) that the actual biggest factor which makes the road bike so much easier to ride is weight (and gear ratios, but that’s not relevant to e-bikes)

      In this case presumably the MTB weighs more, which helps on downhills.

      I think there’s a whole literature out there on rolling resistance as it relates to tire size and pressure as a function of road quality — for really nice pavement/velodrome, skinny tires at high pressure win, but for rougher surfaces (e.g., chipseal or less than perfect pavement) lower pressures can be advantageous.
