During a bike ride, your body generates thermal energy as heat due to muscle and metabolic activities. This energy is not wasted because it helps keep your body warm and contributes to maintaining your core body temperature. Additionally, some of this thermal energy is transferred to the environment through sweating and breathing.
When applying brakes to a bike, kinetic energy of the bike in motion is transformed into thermal energy due to friction between the brake pads and the wheel rims. This thermal energy is generated as heat and dissipates into the surroundings.
During the quick stop, some of the mechanical energy from Will's motion was changed into heat due to friction between the bike's brakes and the wheels. This conversion of energy helps slow down the bike by dissipating the kinetic energy as heat energy.
The work done in moving forward is 60 J, so 20 J of the initial 80 J of energy put into the bike becomes thermal energy (80 J - 60 J = 20 J). This energy is lost as heat due to friction and air resistance during the coasting phase.
Not after riding a bike, but rather during riding a bike. Your muscles convert chemical energy (a form of potential energy) into mechanical energy to do work.

Noise and heat is wasted energy from motorcycles.

The main energy wasted while riding a bike is in overcoming aerodynamic drag, rolling resistance, and inefficient pedaling technique. These factors can lead to energy losses in the form of heat and vibration. Improving bike efficiency, maintaining proper tire pressure, and focusing on a smooth and steady pedaling motion can help minimize energy wastage.

First it's the rider, who'll be turning chemical energy from the food he's eaten into kinetic energy in the moving bike. his muscles will warm up, he'll sweat and that'll be wasted thermal energy. Then ther are the brakes. Every time he brakes he'll introduce friction, which'll generate heat that can't be used for anything. Then there's the tires, even if pumped up good they'll squash a little under his weight. They warm up b/c of the deformation and lose energy that way. And the least amount is bearings. Bearing will always have some friction, which generates warmth, which is wasted.
i think it is kinetic energy to thermal energy.
( 1 ) Inefficiencies within the rider.( 2 ) Energy to overcome air/wind resistance , known as drag.( 3 ) Inefficiencies within the bicycle mechanisms.

Kinetic energy is the energy that comes from motion. When a bicycle slows down its motion becomes less so its kinetic energy becomes less. when you slow down, your kinetic energy is reduced.
