Cadence hack

I needed a way to match the cadence to the recommended speed of the instructor. You connect it to your pedal with attachments that came in the pack.

The bike came in a heavy box and since my husband was at work I called a friend to help me move the bike down to my gym. We took the pieces out of the box upstairs and moved them down rather than taking the whole box down awkward and heavy.

My friend left me to the rest and I put it together by myself in about 30 minutes. It was super easy to put together and if I had help it would have been even faster. Finding an APP I liked was another problem though. I even considered doing videos on You Tube. The APP is so inspiring and has changed my workouts from boring to amazing. Reply 6 years ago on Step 8. I'm guessing more magnets would lead to more accurate measurement?

Thanks for the tip bro. Everything including the code and 3D printing files is open-source and you can check it out here:. Reply 6 years ago on Introduction. It is because the computer only allows you to set the circumference of the tire between 1 - mm, yet we need it to think the tire has a circumference of So if we divide On a road bike using 5 magnets is easier to space as the spokes do the spacing for us, but then you need to divide You can use as many magnets as you want provided you comply with the limitations of the computer you are using.

If you choose to use one magnet, you will have to set the diameter to mm. Useful if you want to achieve a cadence above See my comment below. I used one magnet stuck in the crank arm recess at the end of the left pedal. I programmed the cyclometer for a wheel size of It worked great. I ignored the decimal point for a direct reading of my cadence. I think the author used multiple magnets so the two display numbers would both be large, not the smaller decimal place number.

He said the sun may glint off of the screen and make the smaller number hard to read. I did not have enough wire to reach the handlebar and mounted the display unit on my top tube near the headset. My body shields the display unit from the sun.

It worked for me that way. I was concerned that magnets stuck to the caps of the chainring bolts could come off if I hit a big bump on the road. The recess at the end of the crank arm seemed like good insurance. Reply 9 years ago on Introduction. For each revolution of the device measured wheel or crank arm , the magnet triggers the computer that 1 revolution has been made, and it calculates speed from how many times per minute the magnet triggers it and multiplies by a formula.

Reply 12 years ago on Step 8. I am currently making my 2nd one and I ran into the problem of only being able to find a modern speedo that sets the tire circumference by the diameter ie: 5" to 31". The magic number is As the speedo will only allow us to set the tire diameter in inches we need to divide the magic number by integers until we find a circumference that will most closely resemble the allowed settings.

After trial and error I found that The diameter of a 26" tyre is This is the closest you will manage to get using the range of 5" to 31" tyres so I agree that this will not be the most accurate sensor, however the error will be extremely small between Now we need to make the computer believe that a tire with a 26" diameter is spinning at 8 revs per second which will equal 1rpm of a tire with circumference of To do this we need 8 magnets. NB: This is in no way as accurate as the older speedoes that allow you to set circumference in millimeters, but the margin of error using these exact steps is 0.

If you can get your hands on the older speedoes then I definitely advise that over this method, but this will work almost as well if you can't. Wellington Batista made it! Did you make this project?
