Guess you mean bicycle... or do you mean the regular bikes with engines?
I like bikes(bicycles?). I had one I nolonger own now, that I usually drive to different places,but I found abit difficult to always use on steep express roads. That's probably one of the reasons I nolonger use it.
The peddling features are great for exercising the body... you come home feeling relaxed & in good mood after exercising through a calm/natural places. Hopefully I will find one with engine that is fuel by solar/clean-renewable for occasionally climbing of difficult hills and places.
Bike mean not bicycle (I hope it's clear thinking).
Otherwise If i were talking about bicycle, then there would be a mention. However, I have mentioned motor bike here and it's one of my favorites. But of course it is not good for our body even bicycle is very convenient for our body.
