Re: Electric Dirtbike

https://blog.jktobin.info/wp-content/uploads/2019/09/Capture.png I am messing with a design to mount the battery. I would put poly bushings in these holes and run bolts through the frame and through holes in the battery spacers. This would keep the smaller vibrations down and help lessen the force ...

Re: Electric Dirtbike

Have you assembled the battery pack yet? I have not assembled the battery pack yet but plan to have that in my hands by the end of the year if things go as planned. Do you have any recommendations? I am planning on using dialectic grease between the negative contacts and the aluminum plates. Then, ...

Re: Electric Dirtbike

If you really want a MX bike you also need Torque. This is only possible if you using a 2 stage drive. My recent build has a chain reduction 1:3 on the first reduction and the second gearing is 1:5. With this reduction you will benefit a lot more torque without the heat. The start from zero speed g...

Re: Electric Dirtbike

The only thing I'd point out is that there are a few 150mm hubs which have a 6 bolt brake mount on both sides. Oh thats good to know! I saw a few out there but I couldn't seem to find one that was readily available. The wheels are already built but if things need to change that's good information. ...

Re: 150mm X 15mm Thru with 36h Drilling

The Onyx hub is perfect! Thank you! I am building a custom bike from the ground up but I bought the swingarm from vector ebike to make things a little easier for me. After receiving the swingarm and taking measurements it looks like I need a 150mmx15mm hub. I thought it sounded a little weird at fir...

Re: High Amperage BMS Reccomendation

Sorry for the late replay, I haven't had access to a computer that would let me log in. The BMS I have access to is the link on the bottom. According to the company's very spotty customer service they said it would not support regen braking. Is there a way to test this without hurting the bms becaus...

150mm X 15mm Thru with 36h Drilling

Hey guys I'm looking for advice to try and solve my hub situation. I'm making a dirt bike style electric bike so I will not have a freewheel in the rear. I plan to have it be a direct drive system. After doing some research and seeing what others are doing I plan to use a front bike hub and mount my...

High Amperage BMS Reccomendation

I am currently working on an electric motorcycle project. The project consists of a 20s10p battery pack with a total voltage of 72 and a continuous discharge of 200A. The largest, high quality BMSs I could find for a 20s system were 150A. Looking a continuous discharge of 200A and a controller that ...
