Outside of battery is the direction I will be trying. Daly will be the BMS too

I have my conversion setup the same as Don in a 2010 CRF250 chassis. The main power switch would be all but impossible to hit as your legs hit the bars well before the jewels get close .I'm a young un at 66 and hope to still be riding at 78 like Don. He rips and has a good time on his YZE...

It took 45 minutes to get back to full charge with 2 15amp chargers and the 4000 watt peak 3500 running generator

The 2010 CRFE is still ripping GH. Rode today after a night rain and had a great day. Started on a full charge and after 8 laps on the Arroyo track, vet track, battery was at 72.6. After a bit more testing, the goal is to race a Saturday at the Glen race in the 60 expert class. Charging for...

I was at GH on pick up day. Bike looks and runs awesome. Good job Don.

Being suspension finicky, the countershaft placement would never work for me. I agree with Bearoso

Cool build and great to see the V3 in race situations. Simple and clean is the way to go.

If possible, put terminals out of the battery instead of bringing out cables.

When he started, the battery had 82.3v. That was the voltage when we brought it to the track. After that ride in mode2 and some mode 3, the battery voltage was 76.8 or so. We are still trying to see how much time and performance it has. I rode the bike at Cahuilla today. On the vet track I...

This is bike #3. The original 2004 with ME1304, #2 is a 2006 CRF with V3 and now the 2010 CRF250 with V3 and 50AH 84v batteries. After learning a thing or 2 on 1 and 2, along with Don's assistance, I am extremely happy with this bike. With 24mm triple clamps and 1mm shorter shock, the chassis is...

Don, It was a very fun day at GH with you and the group. Thank You for the ride on the YZE. On the REM track, the power and bike was so much fun to ride. Had a kid on a 450 Husky that talked with me and said he couldn't pass or even stay close. Definitely a fun 5 laps.

chrisflysit, Can you explain a bit deeper for me? Thanks

There is a great deal of very useful info in this build. Don has been instrumental in helping with my builds. If you enjoy tinkering, these are very fun, great performing bikes.

Great build and even with new tires. Looks great

Looks like 3 guys were having a good day!

Doing a few more mods to the ecrf. Just finishing a watercooled heat sink for the controller. With gearing and a heatsink, I'll see if it helps with run time.

Not a lot of thought but 3k or so is probably close. All the wiring and connections along with the parts. The bolt on parts to a frame like a regular bike and add battery.

Thinking about selling my Ebike conversion. I would like to sell the frame, motor, controller, reduction shaft, water pump, battery fan and 72v to 12v converter, Basically it would be without wheels, suspension, plastics, seat, swingarm or battery. Take a look at the photos in the thread and if...

I have a moniter on the triple clamps to keep an eye on too.

Question? If you bypass the discharge on the bms, can you moniter the battery voltage and watch to make sure it doesn't drop below 60v under max draw? This is on a 72v battery.
