Looks like a hell of a lot of fun and who gives a crap if by fitting an electric motor you can climb steeper stuff for climb and ride for longer?
Is it really an different to people buying full suspension bikes and bikes with stupidly expensive, long travel suspension and light weight carbon frames and wheels? The suspension lets you ride stuff you wouldnt be able to on more basic bike and the light weight bits are not dissimilar to electric assist on a heavier bike.
Being able to stay out for hours longer and climb steeper stuff sounds like helping you do what mountain biking biking is all about to me as I’m nt interesting in racing or getting lifts, I want to go out all day and enjoy myself.
