Do the front and back bikers have to pedal at the same speed? If the front biker is pedaling faster than the back biker, how can 2 gears rotating at different speeds work together? As a kid I used to just assume the back pedals were fake and not connected to anything.
In: Engineering
The two cranks are linked by a chain, so they have to turn together.
The two riders are necessarily pedaling at the same pace, but not necessarily with the same effort.
The front guy gets to choose what gear the bike is in.

There *are* bikes like this, *for* kids.
