Electric Bicycle
How does an electric bicycle work?
When my dad first mentioned them to me, I though that they would work just about the same as an electric scooter. But when I actually looked it up, I saw that they still had pedals and looked almost exactly the same as any other bike. So where does the electric part come in if you’re still pedaling? How does it work?
Thank you kindly.
The motor is connected either thru the chain drive or is a part of the wheel (hub motor).
some models are throttle based where you push the throttle more, and more power goes to the motor (Power on Demand ‘POD’), or, power can be initiated by a sensor that detects you are pedalling pretty hard, so it sends power to the motor to help out (pedelec).
On some models you must pedal, (pedalec) others you have your choice whether or not to pedal. Even moderate pedalling helps with the performance and range.
If an ebike follows the U.S. Federal law HR 727, it is legal where bikes are legal:
To be legal in most states, an e-bike must have less than 750 watts of power, pedals that really work, 2 or 3 wheels (not 4 wheels) and the motor should cut out at 20mph.
turn key ebikes can be purchased from Giant bicycle, Target online, and other places depending on your locale. there are many kit vendors; Cyclone is a chain drive, Bionx is a fancy high end hub motor, and Crystalyte is a value hub motor, along with other companies.
The motor enables people that have physical limitations to still ride and manage hills and headwinds. It also allows people to show up for work a lot less sweaty and allows an alternative to car transportation while still getting decent exercise. Prices for decent stuff starts at about $400, and goes up to almost $10K for an electric enclosed trike that can virtually replace a car. Properly chosen many better ebikes have a range of 25+ miles before having to recharge the batteries.
I am 60 years old and can bring home 40lbs of groceries on my ebike, and can use it to go most anyplace in my medium sized (500,000 population) town.
some newer ebikes are quite lightweight and bicycle like.
Ebikes increase health, decrease pollution, decrease auto traffic, save transportation dollars and consume no petroleum. REcharging takes about 4 hours and costs about 10 cents.
