How can I figure out how fast my electric bike would go?
I’m trying to put together an electric bike, with parts from http://www.electricscooterparts.com/. I’m using a standard bike frame that weighs about 30 pounds. How can I calculate how fast a hypothetical electric powered bike will go just from looking at the voltages and amperages of the batteries/motors listed on the website?
wrong data. you need motor rpm and drive train ratios. voltage and amperage gives you power, watts or horsepower. which will let you figure how long it will take to get to top speed.
example: a hub motor with no gears, running at 250 rpm will move a 26 inch bike wheel at about 20 mph.
