Since it is finally getting warm outside again (Yea!) I decided to take out my old electric bicycle and finish everything! There were tons of emails and questions about the bicycle and the motor, so here's a post that'll hopefully answer most of your questions!

So lets sum up the materials:

I purchased the 300 Watt 24V DC Scooter motor (45€) of ebay. The two 12V 10Ah batteries (35€) came from ebay, too. The power switch was extracted from an old computer power supply.

The bicyle itself is a so called "bone shaker" but works perfectly fine. It was very cheap, too.

This is one of the two batteries:





This is the motor with a small wooden wheel from a local hardware store:









Here's a picture of the simple on/off switch:

I tested it on private property. The bicycle is now disassembled:









Facts about the bicycle:

The motor draws up to 16 Ampere when you start the bicycle. 5 to 9 Ampere on normal surface with average speed of 27km/h.

You are allways able to pedal yourself and its not very hard, even if the motor is turned off. I demonstrated it in the video!
