Since public transportation is very expensive in Munich ( about 100€/month ) and driving a car is not an option due to traffic jams I decided to build something on the cheap:
This is my electric bycicle! Its driven by a 300W electric washing machine motor and runs at an Voltage of 24 Volts. According to the manufaturer it spins at 3000 rpm.
Video after the break!
Some more pictures for you!
This is one of the two 12V 12AH batteries I used.
In this picture you can see the on and off switch which i mounted right next to the brakes.
And last but not least there's a little video!
