Review on 🚲 Enhance Your Cycling Experience with the CAT EYE Velo 9 Wired Bike Computer by Mark Kolipano

UPDATE 08/15/2020: To read your cadence directly, set the wheel circumference to 166 cm. Magnets are only needed on one spoke of the sprocket. 8.6 km/h on the display corresponds to 86 rpm. I found it easy to read on the Velo 9. According to a hack I found online, I use my Velo 9 as a cadence sensor. I use a sensor to detect the magnets mounted on the smallest front sprocket on my bike. When setting up the Velo 9: - select km/h as the speed unit - if you have a four-spoke chainring, enter 208 cm as the tire. Circumference - If you have a 5-spoke chainring, enter 167 cm as the tire circumference. (Actual cadence cannot be displayed as the maximum number entered for tire circumference is 299 cm.) UPDATE 8/15/2020: To get a direct cadence measurement, set the wheel circumference to 166 cm. Magnets are only needed on one spoke asterisk. 8.6 km/h on the display corresponds to 86 rpm. I found it easy to read on the Velo 9. Using the GPS speedometer app on my phone, I checked theoretical and actual mph at various cadences and speeds. Actual miles per hour were always within 0.5 miles per hour of theoretical miles per hour. IMPORTANT: Neodymium magnets (rare earths) are not toys! Keep them away from children! Additional Notes: A Velo 7 with a smaller display will also work. It uses the same programming. Ceramic magnets work, but I used neodymium (rare earth) magnets. Neodymium is more expensive than ceramic but MUCH stronger. My smallest chain is convex and has four needles. To bring the magnets closer to the sensor I put two magnets on each spoke. Over 100 miles of driving the magnets didn't move at all. Maybe someday I'll fix them with silicon glue 🙂. I'm an old, fat, out of shape guy (71.5ft 9in, 230#) who gained weight during the COVID-19 pandemic shutdown. Taking cycling seriously (my typical daily commute is 17 miles at an average speed of 18 mph) got me back to my pre-pandemic weight (218#). Judging by the cadence counter, I was pedaling faster than I thought I would. ; a good thing. My "recreational" cadence is around 60. My "training" cadence is 76-86. My "too fast, shift up" cadence is anything over 90. I wanted a cadence sensor that was cheaper than my bike. I wanted to avoid wireless connection issues. My Velo 9 cadence sensor works well and I'm happy with the results.
