xx Electric Hub Motors ... ???
08 Nov 2008 at 19:54 by vja4Him
I'm really a dummy when it comes to anything mechanical or electrical! What would be a good choice for an electric motor for my Electra Townie ... ???

I need to keep the gears that came with my bicycle, so I can still ride my bicycle with no motor as often as possible. I need the exercise and enjoy riding, but also need to commute to various job assignments where there is no bus service, and too far for me to pedal (10-15 miles each way).

I want to get something that will last many years, and allow me to attain speeds of at least a good solid 35mph (45mph would be better, so I could ride on the country roads where the speed limit is between 45-55mph), with my weight, plus groceries (will not be riding fast with groceries!!!, only around 10mph then!).

When I go to work, my weight is around 210, plus my large backpack, which normally weighs around 10-15 pounds. Groceries will add another 15 pounds, sometimes more ....

So, I need a good quality motor that will easily carry over 250 pounds, reliable, effecient, long lasting ..... I've been checking around on different websites, but am still a bit overwhelmed ... !!! Help please ... !!!! Thanks!

This page addresses one of the hardest decisions a buyer has to make.

The short answer is this:

If you have no hills or very minor hills a gearless motor is most definitely the way to go.

If you have steep hills then a geared motor is much much better.

Electric Bike Design & Development

An interesting page with some videos showing their bikes perform.

Have you been looking on the Web for Electric Bikes? We did too - An uninspiring selection isn't it? You will find that the majority produce minimal power, have lousy batteries and look so goddam ugly. Japanese manufacturers are aiming at the elderly; most others are dull commuter bikes for wobbling about on and getting laughed at.

General Questions about E-bikes

   1.  What is an electric bike, exactly?
   2. Are they road legal?
   3. Won't the extra weight make it difficult to pedal without the motor?
   4. How much power does it take?
   5. Does it recharge the batteries while you pedal?
   6. How fast? How far? How much
   7. Should I do a conversion or get a prebuilt ebike?
   8. Environmentally speaking, isn't this this worse than a regular bicycle?
   9. Where can I try or buy one?
