Electric Bicycles, What’s best for me?
Volts, amps, watts, power
Most people when searching for an Electric Bike Motor want to know How Much? How Far and How Fast? The truth is that due to variables there are no straight forward answers to those questions.
It’s a natural human response to want a pre-calculated idea of the return we’ll get back on our investment.
Before you invest money in a stock, you want to have an idea of what the stock price will do in the future so you can pinpoint how much you can expect to earn back. Oftentimes, these types of questions have complicated answers because there are typically a lot of variables involved. Yet despite the variables, we all still want to know what we’ll get for a return on our investment. This is good and this is true, it’s not just about stocks, it’s about any investment that you might make. This could be about a car, home or even food, right now this is about Electric Bicycles.
A look at the variables: The maximum performance for your bike will be determined by the power that you supply through the batteries. Another factor is to make sure that your equipment will handle the voltage that you decide on such as the motor and controller.
Are there hills in the area that you need to climb? how long are they? how steep are they? are you facing head winds? What is your tire size and are they smooth, knobby, wide, thin, maximum tire inflation. How much do you weigh? How much does the bike weigh? Do you pedal? If so, how much?
Without getting to technical, basically the voltage affects the torque (power) and the amp/hrs supply the distance traveled between charges.
There is an accepted industry standard for the most popular motor kits. It’s a good idea to check with the seller to see if their product will live up to this as a minimum.
Standards, using a 600 watt motor, 36 volt battery system on a 26” two wheel bicycle. Assuming you weigh 175 lbs., no headwinds, on flat land and few stops and starts you can expect 20 to 25 mph and 20 miles between charges. In real life, I would expect 16 to 18 miles between charges. These are the ideal conditions.
A Simple un-Scientific Description of volts and amp/hrs and watts
Volts could be translated to power or strength. A big strong guy (high voltage) can push a car easier than a small guy (low voltage), therefore high voltage is more efficient.
Amps can be compared to, how many of those guys you have? They can’t move those cars any faster
but, the more you have, the farther you can move those cars. A lot of Volts can move you up hills and fast. Amp/hrs will determine the distance. Amp/hrs is determined by drawing 1 amp continuously until the battery is completely discharged. If the battery lasted for 12 hours, this battery would be rated at a 12-amp/hr battery. If you really want to get technical, here is a wonderful site

Watts are the combined power of volts and amps, volts x amps = Watts. Watts are used to determine the total available energy that is supplied by your battery. If that hasn’t confused you enough, the wattage of your motor doesn’t give you more power, it simply is the capacity that tells you how much of the watts supplied by your batteries, this motor can use efficiently.
