It's almost that much here now! They're saying more like over $4 a gallon by spring.deardancer3 wrote:With Gas prices predicted to go to at least $3.75 in most of the US this spring, Wonder what ebikes would be the best to advise customers to consider?
All the frames are sold, although they will be finished in February. The price is around 550$ and includes frame ,swing arm custom built for x5,x4 and golden motor with big or normal disc, Left and right canopy made from fiberglass and cheap shock. For two bikes canopys are made from carbon and one from Kevlar. Steel is 4140 only on two frames because it is hard to bend it, all other are from 4120. I will make a topic with all the details but my arm is broken (1 week left in cast...) and have trouble typing... Here is the webpage I made and it will be functional soon. The whole project will be open source so all the details will bet there. http://www.greyb.org or http://www.greyborg.comMicrobatman wrote:HAL9000v2.0
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?
One thing I would like to see - and which I actually approached the CellLog manufacturers about - is a 24s CellLog or similar device. As it is, I'm having to make do with improvised affairs like this:RevDon wrote:I left out an obvious catagory: Accessories. Things like the Cycle Analyst,

There will be a diversity of opinion. Getting one product to market should be goal, so a "one size fits all" approach of best components & methodolgy, with latter product diversification and stratification.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.
I'm no lurker but seriously interested. Most great products start in someone's garage or basement. Think Apple Computer, which this week became the most valuable company in history, exceeding Exxon/Mobil, Microsoft, IBM and so many others. One guy, in a basement with his friends!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
I'm close to completing my manual using the A123 AMP20 prismatic pouch cells and Agniusm's excellent build kit. Those are sine-quo-non now.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.
My company design recommendation is to think of this as a far reaching cottage industry. Components being manufactured in many differenct places and assembleages in those some places. A broad network of folks working & profiting together. Product diversification will happen naturally, in non-hierachical manner. We have to get away from the practice of bloated CEO compensation and top-down styles. Think employee-owned share ownership plans and what-not.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.
Heinzmann, from Germany.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.
Really good design work, then sub it out to one the domestic aerospace engineering companies because they already have the metalurgy, composite, molding and manufacturing know-how perfected.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.
Perhaps, perhaps not. The automobile manufacturers are already well positioned to capture the market. I believe the market here is for what are classified as "light electric vehicles" (LEV's).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.
Count me in, please! FYI, my assiduous R&D work on a newbie e-cycle and battery build is for the sake of New Economy new employment in my own locale. I intend on following through with a solar pedicab design and launch, because its an untapped market where I am. We're all set with local manufacturing capacity and ready to move.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
