Thermal energy is the internal energy of a system in thermodynamic equilibrium by virtue of its temperature.
A hot body has more thermal energy than a similar cold body, but a large tub of cold water may have more thermal energy than a cup of boiling water. Thermal energy can be transferred from one body, usually hotter, to a second body, usually colder, in three ways: conduction , convection, and radiation.
Insulator
A material that conducts electric current poorly is an insulator. Insulators have high resistance to the flow of electricity due to their tightly bound electrons, which do not move easily. Examples of insulators include rubber, plastic, and glass.
One example of a material that conducts electricity poorly is rubber. Rubber is an insulator and does not allow the flow of electric current easily due to its high resistance.
The property of a substance called the thermal conductivity indicates how well or how poorly a substance conducts heat. Insulating materials have a thermal conductivity around 0.02 to 0.08 Btu per hr - ft - F degree. A good conductor of heat like steel pipe has a thermal conductivity of about 24 Btu per hr - ft - F degree.
insulator. Insulators have low thermal conductivity, which means they are not good conductors of heat and help to slow down the transfer of heat. This property makes them useful for insulating buildings, electrical wires, and various other applications where heat needs to be retained or kept out.
The thermal conductivity of a material indicates how well it can conduct heat. Materials with high thermal conductivity, like metals, can transfer heat efficiently, while materials with low thermal conductivity, like wood or plastic, transfer heat more slowly. The thermal conductivity value is measured in watts per meter-kelvin (W/m-K).
thermal insulator
a conductor does, while an insulator poorly conducts thermal energy!
One material that conducts thermal energy poorly is Styrofoam. This material has a low thermal conductivity due to its high concentration of trapped air pockets, which hinders the transfer of heat. This property makes Styrofoam a good insulator for keeping things cool or warm.

Thermal conductivity involves the movement of energy while the as a whole is still. Gases are said to have low thermal conductivity, as they transfer heat poorly. Metals have much better thermal conductivity, as they will heat up and cool down relatively quickly.
Not really. You'll get a bit of heat(thermal energy) in brakes, poorly maintaned bearings and in the rider's muscles - but that's all just unavoidable losses, and isn't helping the ride at all.
