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
An element that conducts heat and electrcurrent poorly, and can be a solid, liquid, or gas is a(n)nonmetal.
Insulator
An insulator. (i.e. glass)
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.

thermal insulator
a conductor does, while an insulator poorly conducts thermal energy!
A material that doesn't conduct heat well is called an insulator.

Thermal energy poorly and slowly transfers in liquids

an insulator
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.
