Hopefully this site will help manufacturers to get a better idea of what the general public is searching for in EMX. I do not use my ebike for any trail riding. For this reason, I am more interested in an actual MX application. As with combustion bikes, enduro bikes have always been a bit...

On my current ebike, I have dual batteries. The lower slides in the side, and the the more conventional top slide. 2 seat bolts, 1 tank bolt and a couple shroud bolts and out it comes. With the seat off, a quick check of all wiring is reassuring. A battery charge from a low threshold only takes...

Funny you say that. My first DIY bike, I did just that. It had a nylon handle with a rubber outer and after releasing the latch, it slide right out the top after removing 4 shroud bolts and setting the tank shell aside. No issues, easy to do and very secure. I guess it would be tough if your a...

I want to clarify, I have not owned but ridden both at different times. Sorry

Interesting comments on the DIY and production E dirt bikes. Without the support of the engine in the frame, handling does change, no doubt. At the level 95% of riders utilize, many of these concerns are minimal in the big picture. Even on an ice bike, which are way beyond the average rider...

2010-2013 CRF chassis is a great platform for me as I have many interchangeable parts. I would probably change a couple things on my bike if building another. Don mentioned you have many skills that will be great assets for your build. I am envious of those abilities Any questins, feel free to...

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...
