bike gear calculator speed

Same goes for the sprocket box, e.g. Use our calculator to determine the top speed and gear ratio for your tire size.  other in. The ratio of those numbers yields the best power (faster acceleration) or the best high end speed, or a compromise of both. or 13,14,15,18,19,21. The higher the gear ratio, the higher the top end speed; the lower the ratio, the stronger the acceleration (power). For the purpose of gear calculatons we add twice the diameter (or depth) of the tyre (top and bottom) to compute rider weight, rim and tyre construction, frame material, wheelbase length, etc. form (in a separate window) and can be downloaded in MS Excel format (see 26" 2.35 Speed -- MPH So, if tyre diameter is only an approximation then it follows that gear calculations aren't entirely accurate. Our cassette page links to additional information on cassette tooth counts. [add 'mm' if 0 The diameter of the 'wheel' is therefore: rim dia. For brands and models not covered, or if building up a custom cassette, you will need to count sprocket teeth and enter the tooth counts under "custom sprockets." 95, to calculate 2.30 44 A clincher tyre, however, is open at the bottom so for the purpose of understanding tyre diameter you have to imagine that If you're using a Schlumpf Drive plus an internal-gear rear hub you should enter the actual number of teeth of the front chainring for the first chainring, and this number of teeth times the Schlumpf ratio for the second chainring. 50 Bicycle gear size and cadence/speed calculator Use this page to calculate bicycle gear sizes (in inches) from any wheel/chainring/sprocket combination. 2.35 (adsbygoogle = window.adsbygoogle || []).push({}); You need to enter data for at least one chainring, and at least The selection of cassettes is up to date as of February 2018 for Shimano, SRAM, SunRace and recent Campagnolo models. For multiple gears results are shown in tabular Problems with this program?

Standard "lawnmower" engines might be as few as 2400 and high performance engines as high as 9000 RPM. After choosing File - Save As To determine the gear ratio necessary for your go kart or mini bike you must know the limit of your top speed. Enter the diameter of the drive (power) wheel and tire combination. Enter the wheel size, tire size, number of chain rings, number of teeth, select a cassette size (and optionally the individual cogs) Imagine your [clincher] tyre is a tube rather than open at the bottom. For single gears results are shown The main Navigation tabs at top of each page are Metric - inputs in millimeters (mm). and since we are assuming that the tyre is round in cross section we can use tyre width as a proxy for diameter. If you do a calculation, get a result, then bring this window to the front, subsequent "results" windows from subsequent calculations may be hidden behind this window. It is important to have the correct gear ratio for the tire size for proper operation of your clutch or torque converter. There are many factors that will load a tyre and alter its diameter. Colors group similar values. Cadence (RPM) File - Save As The gear ratio is 5 and the potential speed is just under 13 miles per hour. 32 Use this page to calculate bicycle gear sizes (in inches) from any 20 mm This page covers most internal hubs back to the original 1902 Sturmey-Archer. Some self-styled internet 'authorities' have it that no gear calculator worth its salt can be without a 52,42. Copy, paste and transfer (email, text etc) this bike data to another device. Clicking on "calculate" generates two new output pages: a full-size one, and a small one which you might print out and tape to your bicycle's handlebar stem for reference. RPM range vs. speed is given in Mike Sherman's gear calculator. When using a torque converter with a go kart you may go as high as 45mph on flat terrain and 35mph on hilly terrain. Enter Shift at RPM, select gear to shift to and hit Shift and Trace to run up through the gears … Many internal-gear hubs listed and some of the cassettes are no longer in production.  Roy Walter. 35 [add 'mm' if required] everyone normally uses) or development (the actually distance in Excel does a very good job of converting .htm, .mht, etc. ©2006– + tyre dia. BikeCalc.com - Speed at all Cadences for any Gear and Wheel How fast will I be going at 30-130 rpm in these gears? comma-separated list, e.g. Mini bikes work best with a top speed of 25mph for all terrain. For mini bikes 35mph is the top speed when using a torque converter. it is a tubular tyre completely encasing its inner tube. 2.25 Please, Zoom out to fit large full scale template images on screen - or to adjust scale to match ruler held against screen, Click Slider to select then use keyboard cursor keys, Create and Print Full Scale PDFs with diagrams on this page (templates), Copy all diagrams on this page to bottom of page - Make multiple copies to Print or Compare Results, If you've benefited from this free service please consider helping us support, Motorcycle Gearing Calculator - RPM to Speed - Shift Tracer - Sprocket and Tire Comparison - Sprocket Spread Graph, All Inch inputs and dimensions are actual physical finished sizes, If the US ever goes Metric, you'll be able to use a Meter to measure Meters - A Meter Meter. Select Speed and enter a value, 20+ is green, 10ish-20, blue, and below 10, red. Bicycle Gear Calculator Calculate the speed and power requirements of different sprocket sizes for different Hub and Derailleur gears Graph and analyse each gear ratio Select your hub type or gear set and graph and analyse each ratio. Drag Max RPM slider to adjust the range of the RPM and Speedometer Gauges. If your browser has a "pop-up blocker" activated, it may prevent the results window from opening. If you're using a Schlumpf Drive plus an internal-gear rear hub you should enter the actual number of teeth of the front chainring for the first chainring, and this number of teeth times the Schlumpf ratio for the second chainring. 2.40, Chainring(s): Rear sprocket(s): The results are the circumference of the drive wheel/tire combo (in inches), gear ratio and the potential maximum speed (in MPH). mydate = new Date(); The selection of internal-gear hubs in the Calculator is complete except for one a few new models whose gear ratios have not been made public, and some very rare antiques. For multiple calculations, you should close each "results" window in turn, not hide them. required].

Enter the published maximum rated sustainable RPM for the engine you are using. + (2 x tyre dia.). Changing the tire size will dramatically change the top speed so if you are going to a larger tire size you must correct the gear ratio for proper operation. 50 Here you can calculate: bicycle gear ratios; speed at cadence in a range of gears. 20 mm 2.30 If you go higher than the recommended mph then the possibility of excessive slipping of the clutch or belt may cause early failure. The diameter is the radius * 2, or in this case, twice the distance from the ground to the center of the axle. 1.5 e.g. There isn't a ready answer for determining tyre diameter as affected by inflation pressure, temperature, Clincher tyres are 'open' at the bottom. 2.40 2.125 23 GEAR SIZE: In the chainring box enter either a single parameter, e.g., 27" calculate speed calculate gear 32 If you do a calculation, then bring those to the front, subsequent "results" windows from subsequent calculations may be hidden behind them. When using a clutch to drive your go kart the top speed on flat terrain is 35mph, if the terrain is hilly or the weight of the driver is high the top speed should be 25mph.
