Here is the image it inspires me: Sorry for the non-French speakers, this is a very good French comic.

Around me, all MX tracks are small with not a lot of long straight lines. It’s not like US where a lot are very large with a lot of straight line. I can’t imagine do a 90 kph on my little nextdoor track! With my offroad skills, I will finish twisted around a tree!

The housing is made! More than 11 pounds of chips lost to do these big hollow parts. Now I think about the two supporting plates, the output shaft and the battery shape. I regret to not having a perimetric frame, with this old one, it is more difficult to integrate batteries (260 21700...

The inside of the first part is made! When I see all these chips and it wasn't the biggest job, I think one day I'll try molding the metal to reuse all that lost material. Now I have to do the fixture plate to mill the outside and put the other side of the piece. After serious work, some...

Thanks for your advice. For the belt, I also have a doubt about the service life. The belt installed on my mini dirtbike is a 5M 9mm and after testing, it seems to resist but it's a small dirtbike even if it can carry about 100kg (me and my daughter) without problem. So I hope that a wider...

Hello everyone, After CAD modeling, I have printed these parts in 3D to see if alignment and dimensions were good. There were small mistakes and I fixed them, now it's time to mill! I think I will make a ton of chips! To be continued...

Hello everyone, I choose to make a belt reduction between motor shaft and rear output sprocket. The QS motor have a 8M pulley but I wanted torque more than speed, it's a dirtbike and on the tracks, the average speed is only about 30kph. With the motor shaft diameter, the smallest pulley that I...

Thank you! Your builts inspired me a lot!

Hello everyone, here is the presentation of my new work: convert an old dirtbike into modern electric dirtbike. After my first try on electric dirtbike with the "small beast" that I set down the power a lot for the kids: it was like a KX or YZ 80cc 2 stroke dirtbike but with the size of a small...

It’s probably a time delayed fuse. It can accept more than its nominal value for a limited time before blows. I dont know the datasheet of your fuse but perhaps you can send a mail to Kelly to have the answer. An example of a time delay fuse: https://www.farnell.com/datasheets/683342.pdf

JimVonBaden is right, the main fuse is on top of the controller. You can move it next to the battery if you want. On my mini dirtbike who use a KBL Kelly Controller, the main fuse is between the battery (+) and the main contactor.

Hello, no need for two fuses in series. Great build!

Hello everyone, this time electric integration and some parts. I try many place but the kelly controller is big and the batteries are at the good place for me so where can I put this thing? The kelly is big but not thick so left side was OK and the other side, I can put all the electric stuff...

Thanks for your reply. It was made in ASA with a Prusa printer. Built with care and a good wire, this printer give high quality out of the box.

Hello everyone, this time the frame. At the begining, I wanted to put this motor inside a racing pocket bike. But my wife's dad gave me this dirtbike frame: A Conti RX 650 Basic. Even Google don't have an picture of this, so if someone have some informations, he's wellcome! So, a bigger...
