Sur Ron smashers

How do you know it smokes a varg?

🤔

Go buy a Varg and we can find out.........................oh wait, nevermind.   

Idk bro sounds like some bullshit

Did you ride one or just taking his word for it?

I’d consider a conversion if I would end up grenading my current 250f motor. 
 

Good on him though for being innovative 

Is that $8K for the entire bike...or just for the motor and conversion work on an existing frame I already own?

Drilled motor mounts? Ti motor mounts? Nah, motor mount delete is where it's at. How else are you going to smoke a Varg without a fourfold increase in chassis flex?

Another answer to a question that no one asked...

Excellent observation Broseph.  The "tin can" surrounding the operating parts is pretty trick as well.

What’s in the gas tanks?

Looks like a death trap. Yikes.

I have a CRF250 with the same package. Unbelievably fun to ride. I do not know how fast a Varg is but I can ride the main track at Glen Helen and get around easily at speed. I have mounted mine with no welding or cutting of existing frame. 2004-2013. Build one, I did.

This is cool to see someone trying, but zero R&D and just putting a massive battery and motor in a frame it was to designed for is likely going to perform very poorly.  It might be fast, but good luck with handling, stability, and reliability.  

Just battery and motor to your bike. 

Thing is reliable man, just believe in the magic behind the sheet metal.

Is the electric motor a Sur Ron, hence the post title? If so these chassis would be a lot heavier for that motor, no?

Manny uses the QS138 70h V3 motor. It's become somewhat of a standard for e-conversions because of its power output, weight, form factor (fits in most standard MX frames), and durability.

I'm doing a similar conversion with my YZ250F using the same motor. I bought my kit through Electro and Co. Most of the products are produced in China, then Electro imports them and handles all of the wiring and programming for the controller. They're based out of NorCal and make everything about as plug-and-play as it can be at the moment.

Until you ride one, you do not know how good they really are. Mine uses the V3 also in a 2010 CRF250 chassis. Power is very good but the handling is so unlike any ICE bike. Very easy to ride and go fast on.

Cool looking bikes.  Here is a cool vid I haven't seen posted with another homemade but advanced electric design that uses an existing chassis-->

My only observation/suggestion would be to get a machine shop to CNC the metal box to make it look like something more than a welded metal box.  I'm sure the performance / power is fantastic.  Hire a 3D CAD guy to model something up for the metal box, have it professionally machined.  I'd buy one.

I work with these guys closely, and what you can do with their conversion kit is pretty incredible.  We used the same QS138 motor for our endurocross YZ build, the bike handled like a champ and it was a huge help for me not having to cover a clutch the whole time.  Using a perimeter frame as a starting point is a much better setup than what we used because you can fit a lot larger battery in between the frame spars, we chose the hardest possible bike to do this conversion on haha.

 FYI, the TruMoto controllers that they have coming out soon are going to be a game changer. . .

There is a possibility of a sand cast battery box but then weight goes up. You could make a billet plate for the base and then have a shop fab a box for the sides then a billet top. i did mine with removal side covers for battery removal and inspection. There are no visible bolts around the perimeter though. if you want to see it on the track, casmoto has a few electric bike videos.

I know Battery Powered is the way to go when anyone can now build a bike without needing to produce an engine.  I do like hearing that it smokes the Varg though.  ThevKTM freeride does that at this point too.  

What are these motor/battery systems being used SX actually designed for.  Dirt bikes can’t be what the manufacturers focus is on.  How do they hold up to being power washed?  One thing (amongst many) I wonder on these BP bikes is, ICE bikes after washing you start them and let them run evaporating all the water around the engine.  On BP bikes, any moisture that possible infiltrates anything just sits there.  Whatever the intended application focus of this system is, was it meant to be power washed regularly?  How well is everything sealed?  Or do people not even know?

There is a rating of different levels of water proof to resistant. Not 100% but I think IP67 is waterproof. These motors and controllers are the waterproof rating. The only area of suspect is the battery and that is why you see them encased in one form or another. I have my bike with removable batteries so washing is a non issue.

Gonna have to add an extra zero to the price tag

Had no idea so many people were doing electric conversions! This is awesome 

8k conversions with no engineering are awesome?

To each their own, I guess.
