A bike is not a simple machine. It's a collection of several simple machines ... specifically, in order to even be a "bicycle" it must contain at the very minimum two simple machines (two wheels and axles).
A bicycle consist of several simple machines, which makes it a complex machine.

No it is a compound machine, seach "bicycle" and "compound machine" on google to verify.a bicycle is a compound machine. it has a wheel and axle and levers. the wheel and axle is the wheel of course, and the lever is the handle bars a bicycle is a compound machine. it has a wheel and axle and levers. the wheel and axle is the wheel of course, and the lever is the handle bars a bicycle is a compound machine. it has a wheel and axle and levers. the wheel and axle is the wheel of course, and the lever is the handle barsbi cycle is not a simple machine
A compound machineA bicycle consists of several simple machines, which makes it a complex machine.
It has many parts that work together to preform a function. Just like other comples machinesIt's got wheels, axles, levers and gear ratios.Because it consists of many simple machines.A bicycle is built up of several simple machines, (the lever, wheel and axle etc), and several simple machines interacting becomes a compound machine.
A bicycle is an example of a complex machine.
