Help me with my bike prob
I have two set of wheels in my new bike, I don't want to use the original wheel set so I switched out to another one. I'm pretty sure that the wheel is not a fixed hub. After putting the cassette from the original set of wheels to the other, when pedals backward, the cassette seems to move into the direction of pedal. Is it possible that I did something wrong, or can it be that the second rear wheel has a fixed hub that allows me to add on gears? I thought fixed hub doesn't have any gears on em...
