Either a battery or a dynamo.
A dynamo
A battery is a device that stores and produces electrical energy by converting chemical energy into electrical energy through electrochemical reactions.
The output of a bicycle generator is electricity, which is generated by pedaling the bicycle to power a generator that converts mechanical energy into electrical energy.
A powerplant
cell
The energy produced is obviously light energy. The energy is provided by the bicycle's kinetic energy.
Thermal energy to electrical energy
The machine produces electrical energy.
A device that produces energy is often referred to as a generator. Generators convert mechanical energy into electrical energy.
"Electrical appliance" is a very general term - there are electrical appliances that do very different things. In general, the electrical appliance converts the electrical energy into another form, depending on the appliance's purpose: a television produces light and sound energy, a mixer produces mechanical energy, a heater or shower head produces heat energy. All appliances will also produce some waste energy."Electrical appliance" is a very general term - there are electrical appliances that do very different things.
