Fixed gear gear ratio calculator.

So, one revolution of the pedals at a gear ratio of 39/28 will take you 3.23 meters (2.31 x 1.4). If you multiply this figure by your cadence – let’s say 100 rpm in this case – you can calculate the speed. In this example, the bike would be traveling at 19.4 km/h (3.23 m x 100 rpm x 60 minutes). Note that other factors affecting speed ...Enter the maximum potential safe engine RPM. Enter the tire size diameter and the target vehicle speed in MPH. Click on Calculate Differential Gear Ratio.

Step 1: Input Your Engine RPM.The formula is: Gear ratio = Number of teeth on front chainring / Number of teeth on rear cog. For instance, if a bike has a front chainring with 40 teeth and a rear cog with 16 teeth, the gear ratio would be: Gear ratio = 40 / 16 = 2.5. This means that for every rotation of the pedals, the rear wheel rotates 2.5 times.

Mar 10, 2021 · For a fixed ring gear, the transmission ratio i r can be calculated as follows using the fixed carrier transmission ratio i 0: \begin{align} &\boxed{i_r = 1-i_0}\\[5px] \end{align} Even the fundamental equation for planetary gears (\ref{pl}) can be expressed by the fixed carrier transmission ratio i 0: \begin{align} Step-3: By Multiplying gear-ratio between 1 to 2 and 2 to 3. We will get resultant GR between Driver and Driven Gear. Resultant Multi Gear Train GR = 0. 5 × 0.5 = 0.25. From the above, calculated gear ratio we can calculate the speed and torque at output gear. Example Calculation. Suppose you’re upgrading from a 30-inch tire to a 35-inch tire, and your vehicle’s current gear ratio is 4.0:1.
