   When braking, depending on the location of the combined center of mass of the bike and rider with respect to the point where the front wheel contacts the ground, and if the front brake is applied hard enough, bikes can either: skid the front wheel which may or not result in a crash; or flip the bike and rider over the front wheel.

3. Reaction wheel - Wikipedia

   en.wikipedia.org/wiki/Reaction_wheel

   A small reaction wheel viewed in profile A momentum/reaction wheel comprising part of a high-accuracy Conical Earth Sensor to maintain a satellite's precise attitude. A reaction wheel (RW) is an electric motor attached to a flywheel, which, when its rotation speed is changed, causes a counter-rotation proportionately through conservation of angular momentum. [1]

4. Reaction control system - Wikipedia

   en.wikipedia.org/wiki/Reaction_control_system

   Alternatively, reaction wheels can be used for attitude control. Use of diverted engine thrust to provide stable attitude control of a short-or-vertical takeoff and landing aircraft below conventional winged flight speeds, such as with the Harrier "jump jet", may also be referred to as a reaction control system. [1]

5. Jyrobike - Wikipedia

   en.wikipedia.org/wiki/Jyrobike

   This flywheel spins significantly faster than the front wheel rolls and acts as a gyroscope, even when the bike is moving slowly, such as when the rider is starting. The flywheel causes the front wheel to respond to a lean by precessing , that is the front wheel turns toward the direction of the lean, which can help provide stability at low ...

6. Copenhagen Wheel - Wikipedia

   en.wikipedia.org/wiki/Copenhagen_Wheel

   The Copenhagen Wheel contained a custom brushless motor, advanced sensors, control systems, and a lithium-ion battery, enclosed within the rear wheel hub. [4] The control system interfaced with a range of sensors measuring torque, power, cadence, pedal position, and acceleration to monitor a rider's effort when pedaling. The Wheel responded to ...
