Default Re: Newbie questions for upgrading

25 to 26 is what I cruise at on my 48cc bike, my son in law and I did over 45 miles last Sunday and most was at that speed. Both our bikes have the 44 tooth sprockets. Are you sure your speedometer is correct? If its a bike computer measure the tire size in mm and use that number, mark a line on a flat surface and align the valve stem with it, then role the bike one wheel revolution and mark that. Measure the distance between the two marks with a metric tape measure and you have the correct number for your tire size.
Your results may not be the same,Greg
