i really really appreciate all the comments and feel i have to mention some of your names with a gratitude of thanks in no particuler order,liveforphysics,slayer,TylerDurden,oldswamm,wingtip,ptd,jonathanm ,Red_Liner740,MadRhino, and all others whose names i have not mentioned all is very very much appreciated....as for the chromoly issue it seems that there are a few people voicing this concern,i for one have a mongoose bike 6061 aluminum frame,and i carry 26lbs of batts which happen to be sitting on a 6061 axiom bike rack,,,and before i had the lifepo4's i had 39lbs of sla's sitting on my mongoose and the frame since 2006 still holds up rock solid,,,granted i do not take this bike off 20 foot jumps but i have hit the occasional pothole with no ill effects to the frame,,,although the axiom rack did crack, it was replaced and if you look at the rack it is very small tubing yet it still holds up to great weight standards and you have to bear in mind the axiom im using is one of their cheaper models,35$,,,at this point i have been using this rack(since changing the cracked one) for 4yrs and its holding up great all told with batts and bags apx 30lbs on stringy 1/4 inch 6061 tubing (approximate guess on the tube size) the first rack i used back in 2006 looked way beefier then the axiom and broke apart within 2 weeks of use,,,,the other part of the chromoly issue is that their are certain members that want to be able to mod the frame and they cannot do so with the 6061 as easily as chromoly,,,to those people i say,,,why not just build a full frame out of chromoly if its so easy to modify? as far as im concerned the 6061 along with the 7075 will be plenty strong as i know first hand my mongoose frame is rock solid,,,,plus planes are made mostly of aluminum and we place our lives in those things. if we were building a dirt bike and taking jumps then we have to consider other materials,,,but in this case i feel the chromoly will just add weight to this frame for a very small percentage of strength gain.it has been made clear to me that the 6061 will be plenty strong and i know my mongoose sure holds up great.
lets address the fatigue issue,,,it has been explained to me the 6061 suffers almost no fatigue issues after thermal treatment and yet some people are complaining that it does suffer fatigue,,,,lets take this with a grain of salt,,,all materiel's will suffer fatigue issues and nothing is invincible,,,here on this forum their are those that test to extremes,nothing wrong with that,,,in the end its always good to know points of failure,,,once i have these frames made i will be curious to test them to POF by placing bags of sand or rocks or whatever in the battery spaces and driving around taking jumps and potholes and post results,,,but in the end we have to realize we are not building dirt bikes,,,these are electric bikes built for paved roads and in the end are simply not made to perform to dirt bike extremes.i think in the end if you start testing this bike to extremes either the actual hub motor will suffer damage first as we have to face the facts those are certainly not made to withstand taking jumps,or we the human will break our bones before the frame suffers,,,so just how strong does this frame have to be?
about the dropouts: you do not see all the details yet of exactly what design concepts are in this frame, and my designer is very well aware of the dropout issue and make no mistake,THE DROPOUTS HAVE REINFORCEMENTS TO THE MAXTHERE IS NO WAY THAT THE MOTORS WILL EAT THROUGH THESE DROPOUTS.PERIOD.
IN THE END THERE ARE VERY LEGITIMATE CONCERNS about this frame and i can go on all day here addressing all issues,,,,but in the end it amounts to this,,,it will be a great frame for the purpose it is designed for,,,i have no doubt that this bike is the greatest e-bike ever for many reasons, a practical E-bike with good speed or as much speed as a modder would like,great for hills,and great range possibilities at a very fair price, i have searched endlessly on the internet for E-bikes in general,,,,some guys out there want 12,000$ for their concept hand made e-bikes that this one will still blow away in terms of range and speed,,,,and yes of course you can use lipos to accomplish greater amounts of batteries in a smaller space,,,just be sure you know what your doing when charging those lipos or say bye bye to your house as it goes up in flames,,,,lipos should always be charged outdoors or in a space ready to accept consequences IMHO.i for one will stick with lifopo4.
no one so far has placed .10 cents on a deposit,,,some are on the fence and others want prototypes built first,,,yea i want a prototype too,,,but i know that in the end its a bike,,,not a Ferrari or a Porsche or a nuclear sub,,,,prototype will cost upwards of 10,000$ easy...all i ask is 25$ from 25 people and i will take the plunge. (not 10,000 people like the guy who promises to make a Grammy award winning record) that really gave me a good laugh and although was a good analogy,to be fair is a greatly exaggerated one.
in the end it may sound ludicrous to ask for such a deposit on such an expensive undertaking,,,but in my view as i stated before if 25 people are willing to buy this then i have a product i can take to market.
