I am 180 pounds and need to be able to climb fairly steep hills. Is 500 watts enough to be able to move as fast as a bicycle uphill or do I need 1000 watts?

Answer
1000w

How can I design an Electric Motor with 10,200rpm or more?

Abdulrahma

First like how many rpm will move a bicycle with a Human weighing 50kg on the bicycle?

Before I ask further questions I will reveal my secret, my teacher gave me an assignment to design a motor which can move a Bicycle instead of pedalling.

My problem is the only motor I ever designed is the simplest type.

Question:

1. Can a motor with 10,200rpm move a motor cycle (It drives Air Pumping Machines )

2. How to design? I have the Heavy Guage Magnet Wire

3. The only source of power which I have to run this device is just 12V and it'll work for 5 minutes probably. Please do you have any better Idea or any other simpler, smaller and better source or some kind of igniting device to make the motor continue running with out burning the out the 12V.

I found some informations on Discovery Channel and but it was more like an advert, it was talking about some modules. It was not clear.

Please, I need helps here.

Thanks.

Answer
There are applications where you need a high-RPM motor, but driving a bicycle is not one of them. Of much more importance is the power required: how fast does the thing need to move up a hill? Once the mechanical power is known, and you have some idea of the nature of the drive train (which will reduce the motor speed down to 100 RPM or so at the wheel), you can pick a power and speed which are appropriate.
