The ultimate brushless electric bike motor? from ampedbikes.com
Brushed VS Brushless??????????
What's the big difference? The main differences are that a brushless motor is close to 30% more efficient than a brushed motor. This means 30% more range/distance. The main reasons that brushless motors are more efficient is that they are microprocessor controlled in the same way that the magnetic levitated trains are, the microprocessor reads where the motor is and tells the next electro magnet to push it along. Also brushed motors lose much of their power due to heat loss at the brushes that rub on the shaft.
Now with us in a gas crunch and to be honest I'm not a tree hugger or anything but I see pollution in many many forms all day long and I am really tired of it. The hub kits added on to your bike will drive you about 1,000 miles for the same price as a gallon of gas and not produce the gasses your car or truck puts off.
I am 38 a little out of shape and about two years ago I went to the bike shop and bought a good mountain bike to ride around on and get more exercise, I got it home and ride it for a week or two, then rode it again a month later then 6 months later it was in the garage, tires flat and dusty.
I realized that the ups and downs of hills, wind and stuff that didn't bother me as a kid DO now. But I dearly missed riding down the street on my bike , going on long rides, smelling the different trees, seeing different type of terrain that you cant see from your car. So I set out to find a solution.
I tried many different types of electric bike kits and to be honest they were all very similar but the price from one to the next was insane!
All of the designer brand name brushless hub motors are all basically the same with the exception of the windings and bearings. The windings inside the motor simply determine torque or speed, much in the same way gears do and the only other thing was the bearings, but the kits vary in price from $400 all the way up to $1300.
