That frame is exactly what I want!!!
I have gone through the entire process of switching out from wimpy aluminum frame to a heafty steel chrome moly frame (a hardtail Azonic Steelhead) to lower the chances of my X5 from spinning in the dropouts.
Now that I see what you designed here it would be nice to know that I have a choice to take it to the next level and would be willing to change frames again.
My point is that I think that off road type high performance user would be willing to change frames.
What would be a ball park cost of that frame?
What about the cost with a swingarm capable of holding onto an X5 motor?
What type of material would you reccommend it be built with? 4130 Chrome moly?

Regardless of personal politics, agendas or motivations, I think it's safe to say that we all believe EV's are the future of transportation.
To that end, it's in our own best interest as a group to decide what works, what doesn't, what can be improved upon and how, and what's needed that doesn't currently exist.
Within this group resides experts in every field required to advance the research and development of the products we will use every day, and make them safe and reliable. I'm going to name some names, and if I leave you out, please don't be upset, jump in to your favorite topic(s) and get involved. Who knows, we may even pull in some lurkers
Let's start with batteries. I know that much has already been discussed on this topic, and the others to follow. What I want to do with the EV Business page is to refine what's been said to it's essence, and have it be presented in a marketable format that is mutually beneficial to those wanting to get involved in EV's as a business. An EV Bible, if you will. I've asked Doctorbass if he would be willing to put together a manual on building A123 battery packs, BMS's and chargers. He said he would. (You're still OK with that, right Doc?) Ypedal has vast experince in other formats, (as his bank account shows) and we also have input from representatives of other commercial products, such as Sam from Yesa and Joshk who sells Valence. Take the ball and run with it.
Controllers: Messrs Fechter and Safe immediately come to mind, with Bobmcree and Doc et al, welcome. Some major headway in product development, design and improvement has already been posted. If you would, please start with the current state-of-the-art controller and pursue the development of a modular design that would adapt to the different requirements of the users. Maybe even a basic kit that could be built by newbies like me. You might also include plug / regen braking in this topic.
Motors: Here we're at the mercy of the manufacturers. Hubmotors are mostly all Asia based. From what I've been able to gather from the posts, they will build to spec, so let's determine who offers the best products, who's willing to work with us, and who will actually deliver the goods. Knoxie and Xyster, help us out, You guys make great test pilots. You two, and maybe Recumbent can also offer your input on chain drives and motors.
E-bike Frames: This one's wide open. Suspended, rigid, mountain bike, cruiser, chopper, recumbent, and Beagles scooter, there's something for everyone to get in on. I also want to use this topic to continue the "Perfect E-bike Frame" discussion in relation to them all. Let's come up with something built around the drive, be it hubmotor or chain, that will set standards for a new industry: Ours. I've even seen Safe and TD actually agree on some issues regarding suspension.
I know that I've been largely cyclo-centric here, but I want to include the Auto crowd as well. Most of the technology translates to both markets, and when cross-over applies, let's use it to our mutual advantage. Communication between disciplines can yield new products and ideas, so let's start talking.
There you have it: my Manifesto so-to-speak. I hope it becomes a mutually instructional and inspiring discussion for all involved, and I look forward to being a part of it. Don
