There are some who ride EMTBs but feel
they themselves are cheating if they do not stick to ECO or even motor off!
Many of those choose the lower powered EMTBs....Levo/Kenevo SL or Orbea Rise.
Clearly there are many different types of bike rider each seeking different things from their ride.
There are those that ride partly or even mainly, for fitness, or those that enjoy the sense of achievement from hard physical exertion. Those groups tend also to aim for better segment times or longer distances or greater elevation.
Then there are those that love exploring offroad on a bike, or get most pleasure from gravity runs, and simply see no pleasure in getting hot sweaty and physically drained in doing so.
There are those of course who want to carry on riding but have to deal with some restrictions whether that be, poor fitness, injury, general health, or just the diminishing strength and fitness due to age.
I believe the only group that calls other riders on EMTBS cheats are those that in that last category.......... that cannot afford an EMTB!!
