Koso speed ratio
When I got my Koso meter, one of the functions was to enter a ratio factor for the speedometer. Now Koso gives you a formula for establishing a percentage factor if you so choose, but from what I've read on the Bolt forum, the majority of the folks there, are in the 60 something percentage. Here on our site, SCRBEN has used 98% and it was pretty close to his GPS. So today, with New England socked in with ice covered snow, and me being retired and house bound, I figured that I'd go to the garage and ACTUALLY measure the distance for one revolution of the rear tire, and do the math that KOSO has given in the instruction manual. While not scientific, I measured 79.375", or 2016.125mm. When this number is divided by 2080mm from the instruction formula, a ratio of 96.9% is given. So SCRBEN's ratio entry is pretty close. I won't be able to actually verify this 'til spring, but if someone that is also using the KOSO meter, give it a try and let me know if it works, or not
