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!
DAMN. have you worked out the wattage pulled by the motor, and how many kWh the batteries can provide? vs the actual run time??? i would love to see the percent effectiveness!
ReplyDeleteThis isn't the first one of these I've seen but it is described/detailed the best...well done and thanks for sharing. I'm a bit of a DIYer myself :)
ReplyDeleteThat's awesome I want one :)
ReplyDeleteExcellent!
ReplyDeletehow far and how fast with how much watts can you ride?
ReplyDeleteWhere did you get that kind of DC motor from a washing mashine? I thought they were AC motors and not only 24 volts! Would be a cheap way to get motors for small projects (robots etc)
ReplyDeleteThis is cool, but didnt you get trouble with the police???
ReplyDeleteAfaik the maximum power allowed for pedelec, here in germany and the whole EU is 250Watts.
great project really want one
ReplyDeleteThose wires are too small, for me. I think they gonna get hot when you have load (uphill) and you'll gonna waste energy.
ReplyDeleteInteresting, I had no idea they used brushed DC motors in washing machines. Any experiences with the friction-drive on a wet road?
ReplyDeleteI've got the same motor, it was in an electric scooter.
ReplyDeleteDang bro, that's awesome! Seems kind of scary riding that at full speed doesn't it?
ReplyDeleteWise purchase!
ReplyDeleteNice try !
ReplyDeleteCould you give the reference of the washing machine motor, it would be precious for evryone ?
Thanks again
Nice one!
ReplyDeleteIt would be nice to know which motor you used...
Also if you wheter used an Inverter (from AC to DC) or not.
I'm looking forward to disassembling my old washing machine :)
Thanks for sharing thuis
Ric.
And now I want one!
ReplyDeleteThis is excellent, where can we order one? :-)
ReplyDeleteperfect for the tiring uphills

ReplyDeleteI'm torn between making it and just taking the ride to lose those extra pounds!
ReplyDeleteWhere did you get the pullie for the motor?
ReplyDeleteI want to know also :)
DeleteI would like to know also
DeleteWhat range do you make for one cycle battery?
ReplyDeleteThis is the simplest way to have it work but with time of using brush from the motor to rub on the tire, I guess the tire will get worn out so easily fast.
ReplyDeleteBest I can see you made a pully wheel about 5 inches from wood and attached to the motor.Then you put some rubber around the wood and use that to connect to drive wheel.I will washing machines but I assumed that inn Europe they were ~240volts AC and in USA were 110v AC I Will check that. ~9 amps draw with 24 volts makes it about ~220watts .I2 amp batteries are not great range probably ~15 miles. cheap and cheerful would suit my needs.Well done
ReplyDeleteWhat did you use as a wheel to rotate with the wheel of the bike?
ReplyDeletecan you tell me the exact make and model of the bicycle you show in these photos? I just purchased one just like this here in the United States and I can't find any info on it! I was also wanting to know the price of the bike. (I love the motor idea too...I just need to know about the bicycle though.) Please email me if you can at fowlertami@gmail.com Thanks!!!
ReplyDeleteSieht cool aus.
ReplyDeleteIch denk, wenn der nächste Winter kalt wird, ne tolle Alternative zum basteln.
For all the people asking about the motor, i can tell you that it is made by Unite, it's a permanent magnet DC motor made in china, they can be found for sale on THE auction website by typing in "electric scooter motor" you'll find many power variants at reasonably good prices.
ReplyDeleteCiao, come è fatta la ruota che hai applicato al motore, grazie
ReplyDeleteI am a young man from Morocco and I want to buy one from you, how do
