A dynamo
Yes, it is possible to convert the rotational motion of a bicycle wheel into electrical energy using a device called a dynamo. A dynamo is a small generator that contains magnets and a coil of wire. When the bicycle wheel turns, it spins the dynamo, generating electricity that can be used to power lights or charge batteries.
Because it is a generator. It picks up kinetic energy from the wheel, and turns it into electric energy.
Brakes turn kinetic energy into heat.
A bicycle has mass, substance. So it will have the energy that's locked in the material it's made of.
A dynamo converts rotational energy into electrical energy. A good example is one used on a bicycle to generate power for the lights.
To turn the dynamo in order to make electricity.
The output from the dynamo varies with the speed of the bicycle. And as a geared bicycle is likely(but don't have to) travel a bit faster than the single speed, it may produce a bit more electricity.
