To have the option of keeping up with slow moving traffic mid-lane, also to make cycling around roundabouts safer, I'd rather like a higher legal speed. 22mph would be ideal from my point of view, my bike can do that - before I knew it was illegal, I was zooming around all over the place at about 22mph, on my BBS01B 20" wheeled Dahon folding bike conversion, pedalling lazily and deliriously happy. I wouldn't mind a higher speed limit than 22mph TBH. With 52T>11T, I have 94.55 gear inches = equivalent wheel diameter.
Circumference = 2 X π X radius = 297.02 inches per wheel revolution, x 90 per minute = 26732.097 inches per minute. There are 63360 inches per mile, therefore 63360/26732.097 = 0.4219 miles per minute. X 60 minutes = 25.3mph max. Now that I've increased controller amps from 15A to 18a, I might manage 90rpm - if memory serves, there wasn't enough power for me to pedal that fast with 15A. If not, and because
@Nealh has calculated my LG MH1 celled battery pack is capable of producing 25A continuous, I could uprate my battery BMS for a 30A, and set the controller's amp limit to it's maximum of 20A, using 2A extra for my lights = 22A, leaving 3A headroom. With a 60T chainwheel, max speed at 90rpm would be 29.18mph (if 20A is enough), which could get my amusing looking small 20" wheeled Dahon folding BBS01B bike conversion into the S Pedelec category. I'd need a 103T chainwheel at 90rpm for 50.14mph, but I certainly wouldn't do that with a folding bike.
I'm not suggesting higher pedelec speeds should be used on cycle paths, just roads. Even if speed limit was increased... because cyclists are invisible to drivers, I'd probably still cycle on the left. I shall write A Letter.
