Webb2 jan. 2024 · Bikes need a chain (or belt) to transmit power, and that chain needs gear teeth on both ends to grab on to. The front gears are bolted to your cranks and the rear gears are bolted to the rear wheel, so the front-to-rear gear ratio determines how your pedaling force gets transmitted to the rear wheel. WebbThe chain transmits the force equally, but the change in radius produces a change in torque. So if the wheel and the pedal gears are similar in radius, the behavior is similar to riding a mono-cycle: all torque applied is … the cpu wars

"WebbGears. Chain transmission. Gears are a mechanical system made of two discs with teeth that mesh smoothly into one another. The two gears are in contact at all times as a tooth of the driver gear pushes a tooth of the driven gear. The driver gear transfers its rotational movements to the driven gear, but the gears turn in opposite directions. " - Physics of bike gears

WebbShort answer is that constant power results in constant velocity regardless of gear ratio. Gear ratios change angular velocity and torque but because the product of the two is constant power remains the same. Power at the rear wheel = power provided by rider - power loss in drive-train. Webb4.1 Gears control an output force or displacement or speed. Everyone is familiar with gears in human engineered devices. A gear is a device for controlling an output force or displacement or speed given a certain input force. In a bicycle, we apply an input force to the pedal and crank and get an output force of the rear tire pushing the ground ...
