I just worked it out at 16" @ 15mph = 78.782 rpm .  :P Im knackered , so I may have worked it out wrong. Will double check later. Can I ask... Why  ??? Other c5's will be different to one an other due to motor condition though. reet, am off ta bed.

thanks! i knew there was a way to calculate it but couldn't remember

why i want to know:

well, i live in quite a hilly area and seeing as i have 4, bosch 400w motors lying around i'm currently playing around with the idea of making a high torque c5 with the same speed as the original c5. using a metal gearbox and metal drive cog. also incorporating disk brakes, reinforced chassis (tempted to use some of my 5mm HARDOX 450  ;D :D) , and use a 4qd to control the motor (maybe a relay if i'm too poor as i have one lying around and i can get them for about 30p  ;D). anyway i needed to know so i can work out what ratio to make the gearbox and timing belt.

tired now so i'm off to bed  :)

250W is the maximum legally allowed for use with the C5.400w renders it illegal for road use. I live in a hilly area and use the 375 watts or so of leg power  to assst the motor in going up hills.
