Here is a 2005 CRF 450 conversion I'm building for a good friend. QS 138 72V 58AH EBMX X9000

The X-9000 thumb brake is simply awesome. The thumb brake has so much strength I can easily skid the rear wheel.

Hi Guys, I know that in the "heat of the battle," it is hard to keep from using all the power available. @fmxxx666 sent me his X-9000 settings and they work really well. In the upper two power levels, I can barely hold on to the handlebars. The front wheel just doesn't want to stay down...

A watercooled QS138 would be very nice. It is conceivable that we could convert a motor to watercooling. Doing so would require designing and fabricating a replacement aluminium motor housing. Any thoughts @DonCox ? Here is a QS138 90h watercooled motor: https://a.aliexpress.com/_mPtTWMr I...

Thank you for your kind offer. I would love the purchase these items from you. Please feel free to email so we can make arrangements.

At this point it is air cooled. After testing, I'll most likely take @DonCox 's advice and add watercooling.

Thus far I love the X-9000. And, I love the thumb regen lever. It is stronger than the rear foot brake. I can skid the rear tire on asphalt with it. @fmxxx666 your X-9000 settings worked perfect. At 350 amps and 900 phase amps I can barely keep the front wheel on the ground. I can't begin to...

Here is a short video of the first ride on my just powered-up 2020 CRF 450. Thank you @DonCox and @fmxxx666 for your tips and suggestions. The EBMX X9000 controller is smooth, very responsive, easy to program and delivers more power than I can deal with. -- Dave

All the brackets are welded, the master switch is installed and I just have some minor wiring to do. I’m getting excited to power it up!

Yesterday I finished the last of everything except wiring the master battery disconnect and resistor. I just need to create a break in the positive electricity flow using a BEP disconnect switch. 1. I'll take positive 4 AWG cable coming from the battery and cut and solder new lugs on to both...

@fmxxx666 This will save me a considerable amount of time! My email is dave.daum@gmail.com Please feel free to email me the the password. Best, Dave

Hello @fmxxx666 . Thank you for your kind offer. This is my first EBMX controller installation. I would absolutely love your help with the settings. Screen shoots and passwords for unlocking the full settings would be a big help.

Almost ready to power up.

Here are the dimensions and specifications for my battery. So far Amorge has built five of these for my use. I believe @DonCox built one to these dimensions with different battery cells and BMS specifications. @fmxxx666 built a very similar battery with more space up top for added voltage. Thus...

I bought a second 2020 CRF450R roller. I know, one is enough. It is amazing how many blown up bikes are out there. The electric conversion gives a new, and better, life back to these great bikes. This second bike is super clean. It is almost completely stock. The 2020 I'm presently building has...

Greetings @fmxxx666 I’ve been riding my first CRE with a 13/48 sprocket set. That has worked great. I may start with a 13/52 combination then test other gearing combinations. I’ll keep everyone posted on what I like for different motocross tracks. — Dave

The most difficult task was cutting the titanium fuel tank to clear the battery. The battery can be hot swapped in about 2 minutes. Notice the height of the battery and how the back end of the tank has a big cutout. The entire bottom was removed from the tank. Hopefully these photos show the...

Hello Gang, Recently I purchased a pristine 2020 CRF450 rolling chassis with a ton of goodies and about $4000.00 of Racetech suspension work. This bike will become my MX track bike. Battery = Amorge 72v 58ah Molicel P45B cells. Motor = QS138 v3 Controller = EBMX X-9000 VESC Right now I have...

Here are some photos showing a 2014 YZ250F built using an E&C kit.

I have a 2017 150 XCW that I'd love to convert to E power. I'll have to get together with @DonCox for some insights.
