Price of electricity for an electric bicycle.
I have questions, but no answers. Please help. Thanks.
What is the price of electricity at the wall outlet? Here it is $0.13 to $0.23 /(kilowatt-hour) + 7.5% tax. Some electric companies have a stepped price schedule so that the rate increases with total usage. How efficient is a battery charger? Does 60% of the energy out of the wall get into the battery? How much power goes into overcoming rolling resistance and wind resistance at 15 mph? How efficient is the electric motor? 80%? What is the price of electricity from wall outlet to rubber on the road? -- Michael Press |

What type of batteries?... but thats sounds about right for a ball park How much power goes into overcoming rolling resistance and wind resistance at 15 mph? Depends on the type of bike of course.....120W for a ball park http://www.kreuzotter.de/english/espeed.htm How efficient is the electric motor? 80%? Again sounds like a good enough number What is the price of electricity from wall outlet to rubber on the road? So 120W at the wheel equals 250W out of the wall. So if you carry a big enough battery for 4 hours (1kW/hr) it will cost between $0.13 to $0.23 + 7.5% tax, not bad for a 60 mile trip, of course at 12V that would be a 50Amp/hr battery |

Then he can make it from Los Angeles to Las Vegas in one trip. -- Phil |

So if you carry a big enough battery for 4 hours (1kW/hr) it will cost 1 kW/hr is not a measure of energy. Could this be 1 kW-hr? between $0.13 to $0.23 + 7.5% tax, not bad for a 60 mile trip, of course at 12V that would be a 50Amp/hr battery 50 Amp-hr @ 12 volt? Keep your units straight, and they will keep you straight. -- Michael Press |

An e-bike came in the shop last year and that thing was a pain. Truing the wheel required disconnecting all the electrics. Not the best thing to do. -- Phil |
