A while ago i bought an X7 for about 50$, back then it was kind of a wreck. The pull starter was broken, it had no fenders, flat tire, front fork was not bouncing back and the electrical system was a mess.
Now, a few months later, I've fixed most of these things.
It still has no fenders, front light or front blinkers but I'm gonna fix this in a while. The engine runs quite nicely tho and i am able to drive it.
So, why do I post this in the electrical-forum? I am planning to convert it to electric. I've ordered a Turnigy 80-100 7kw motor, controllers and some accessories to make it run.
What's left to get is:
- a battery pack
- copper wire to rewind the motor (I am planning to run it @ 24v and not 48v as intended)
- some wires and connectors
- a suitable throttle controller for electric
I tried to upload some pics for this post on the forum, but with no success. I would be glad if someone told me how to do, it's more fun with pictures.

to upload pics make a photobucket account and upload them to the account, then post the web link of the pics here.
why not run 48v? youll get more power. im sure you can even run 72v into that motor.
bikerpbl: Thank you!
Bluethunder3320: I'll get the same ammount of power, just forgot to write that I'm gonna run it @ 300w
bassiclyloudog: Thanks, thats the motor and the controller I am going to use, but I am gonna try to run two controllers in parallel on the same motor. There is a few winding types suitable for it but i have not completely decided which one to use yet. The controllers will not have electrical contact of course.
what kind of bike is that in the pic bc i have the same one i have been asked what kind it is and i dont know so maybe you could tell me and what kind of engine do they run bc mine does not have one
Today the motor and stuff arrived, and i fixed a PB account so that i can post pictures here!
Heres the victim for my cruelness:
And here's the motor:
I am gonna rewind the motor to run at 24v 300A with dual ESC:s. I am also thinking about changing the sprockets and chain to something more durable, don't know if its necessary tho.
Haven't looked at how I am gonna mount the motor yet but it shouldn't be to hard.
Need to get some throttle that can control the electrical stuff to, am thinking that I'm just gonna hook up the pot from the throttle to the servo driver.
Feel free to comment!
Now I have slaughtered the motor, and a classmate of mine got me copperwire which I'll hopefully get tomorrow.
Here's som pics of the slaughter and unwinding of old copperwire:
Breaking into the shell:
Got the stator out and removing the bearing:
Do you have any updates on the project I am making a trailer to go behind my pb with the same controller.
No not any important ones. I had very little time for the project after this so the latest updates are:
- I have rewound the motor with two parallel wires (DLRK) for my dual esc-setup. I'm gonna varnish (is that the word?) it with some high temp coating before I put it together.
- I have removed the engine from the pocketbike, I'm gonna consider using the reduction gearbox for the electric motor.
- I have started to make the cooling for the two ESC:s. Planning to continue this today.
Awesome,great job.Do you think you could post some pics of the motor and cooling system.
