It looks real nice. What cells are you using in your battery. Why did you compromise the frame. I got a 20S12P battery in the same frame with a lot of space left. We build our bike to run on the MX tracks, and I do not modify frames because of big jumps and the stress. Your work looks real...

Thanks guys for all the interesting points of view. There is a lot of diversity amongst all of us. My reason for building Electric Dirt bikes comes from riding dirt bikes for almost 60years, and having the great fortune to be able to still ride. I started building them 15 years ago because I...

People are racing YZ250F bikes and 450F with electric power trains. Practical experience says it works. Do you even ride a bike Erwin P? Here is a friend who races them in Florida with an A rider who wins on a YZ450F EBike. The wheels aren't falling off the bikes. They do 1 or 2 laps and...

If Yamaha wants to enter the Ebike market, they should follow some of what Stark is doing, but also listen to what the riders want. The weight is a killer. The Whoops at the first WSX killed the Starks, but they weren't the caliber rider as the lead riders. Yamaha has a perfectly good...

Build your own on your favorite bike/frame. I like the 2014-2022 KTM 250SXF, I have built new and older Honda CRF's, Yamaha YZ250F and 450F 2014 and newer. I am 80 years old and here is mine at The World Vet Nationals, with me on it. I can give you a list of the parts and power, if you want...

I mounted the controller on a 1/8" piece of aluminum. and the cooling plates on the shock side. You can cut the plastic to allow the cooling plates to fit. The controller in a closed box will heat up. Mine did. with the cooling it is amazing how cool it now is. I ran 3 full motos at Glen...

Just for information, These races at Glen Helen were 4 laps per race, 400A (Sport Mode) for the start and the rest of the race with plenty of power in 300A mode. About 15 minutes. The outside air was 80-85 degrees F, The controller was just warm, The motor was hot to the touch but not too...

Thanks it surprised me too. I got 3rd in the 80+ Vet class. A 1st in the fist moto and then 2 3rds. I posted a YouTube of one of part of one of the motos in the post above

Dave, I raced the Dubya World Vet Nationals this weekend at Glen Helen. In the 80+ Class. There were 5 of us. Great fun and a great track. Here is a YouTube of the late race with the tore up track and terrible sun shadows. The other 2 motos ( no YouTubes) were the 2nd races ( of 25 races)...

I'll be glad to help you Dave, but you are a master builder already. That is a great choice to build everything lays out so well. Like I said to you in a text, I am racing mine here at Glen Helen this weekend at the Dubya World Vet Nationals.. Up to the top of Shoei hill and down up to the...

Thanks.

Hey Vince, there was another thread on here about the EBMX x9000 V3. The contact over there is a friend. Bridger Hombreverde at support@ebmx.com he has a KTM Freeride with a QS138 70H V3 and the X9000

Thanks for the reference Philip, but Vinsanity and I have been talking for quite some time about this problem and others. My Far Driver Controller experience is limited. So Ryan Goodyear is a good answer. I corrected my problem on my Votol EM260S controller by replacing it. There must have...

A friend works in Support at EBMX . He said send a request for the pinout to Support@ebmx.com and he can send it to you. He has also asked ChargedCycles when will the Harness be available, he just sent it and is waiting for a reply. Good luck Don

I have actually tore apart a Stark battery. The cells are now propelling my KTM DIY Electric Dirt Dike. They are not easy to take apart, but you can find defective batteries around for about $500. The complete package, like above, is probably worth somewhere close to what he is asking. Here...
