The Electric Bicycle is now starting to get some traction in the heads of the American consumer and the American market. Like every new technology or product, there are an array of offerings from very cheap to very expensive, from crap to nicely engineered and marketed by everybody and his brother-in-law.
If you wish to benefit from the new technology, just how can you decide what to purchase and from whom? Listed here are a few ideas which might aid you. You can buy a 1000w fat tire electric bike through the internet.
Electric bikes are limited by US Federal law to 750 watts and 20 miles per hour. There are a lot of bikes and kits on the market that advertise power as high as 1000 watts.
There are two ways to measure wattage, the initial surge or "peak wattage" that the motor puts out when it is first starting up, and the continuous wattage that the motor operates under.
A lot of very high wattage motors are advertising their peak wattage, not their continuous output. As a consumer it is very difficult to tell the difference, but you can always ask. A tipoff would be a relatively large motor such as 500 watts that operates on a lower voltage battery such as 36 volts.
A genuine 500 watt (or larger) continuous output motor would generally use 48 volts or more.
