new eZip motor

[ronnieb52]

LC

do you know what the RPM is with this new motor ?

Can you install one of your saw blade gears on the motor ?

Could you use JB Weld to hold the gear on to the motor ? With some bolts of course .

Have you figured out how many batteries you will need to power this motor up ?

Oh and have you downloaded the spec sheet for the controller yet ?

I'm thinking that you will need more than 24 volts to make this work.

As the Hub Motor Turns and the LiPo Fire Burns. A brand new sport. Robot bike drag racing.


https://www.youtube.com/watch?v=LSZPNwZex9s

There is little or no reason why this technology could not be used for any e bike not just the ones in the video unless there is a patent or something.

Basically drag racing of any type requires a strict set of saftey rules and regulations which in fact significantly adds to the price of the motor sport.

If racing bikes WITHOUT a rider the costs would be reduced dramatically. It would take much of the fun out of it but the bike rider could still ride it on back roads or in the country but the quick 0 to 60 or 100 + mph would not be needed which would also reduce stress on the frame as acceleration could be achieved gradually with a rider and during drag racing there would be no weight ON the bike reducing stress on the frame.

This my friends out there is my genius clearly shining thru and I would like all of the great minds here on endlesssphere to please work together so we can invent this new sport in the next five years or so. I am willing to pay the money to build the bike with the FX 75 - 5 motor on the back and the 40 kilowatt peak motor on the front.

Also I am fairly sure I am not the only older person who has heart conditions which could pose a direct threat to their health drag racing. There are probably many retired drag racers who are either not physically healthy or too old to be in a racing type of Motorsport. This being a perfect new sport for anybody. Not just the young and healthy.

The controller being fully programmable as I have been told will allow me to ride the bike and SLOWLY accelerate to about 50 or 60 mph or even faster on a smooth flat country road which goes straight for several miles with little or no traffic. I would still wear full motorcycle gear with a crash helmet.

Then the bike will be programmed to go ALL OUT from zero to maximum speed on a drag strip with NO RIDER Safety being no issue may the fastest bike win. Thanks and I hope to hear from everyone regarding this subject. I am hoping that when this bike is finished that Liveforphysics himself will come and ride it.

Liveforphysics is totally awesome and I want to thank him publicity here on this forum as he is a huge inspiration to all EV lovers all over the world. I know he has sure inspired me.
In closing please help me to research the technology and post anything on the subject of self driving e bikes. Thank you all and please post when you can.

But this is no risk! He'll buy a prototype technology probably worth millions, (he's willing to pay for it) so we can do this "sport". (Is it still sport when there is no human skill involved?)

He's dreaming and possibly trolling. He knows it won't happen, and only calls his ideas genius when he wants a reaction.

That self driving bike sure is some serious technology.
It looks like more than a prototype as in the video they got little kids riding on it so it must be safe.

I really cant understand how it can self balance like that
I just would like to know how it is physically and mechanically even possible. It looks like magic to me.

Does anyone know how they do it because it looks like an anti gravity device to me.

Also I wont be using the 29" frame. Also even though I would like to put the 40 HP motor on the front I doubt I will ever be able to afford it.

I will be using a front end equal to that of the original deathlike. I am looking in craigs list for a 125cc dirt bike with a blown motor for parts.

I am not sure if I am using the entire bike frame or if I am only using the front end like the death bike.

Therefore if I could afford to a front hub motor would be possible.

Either way I will need some help installing the FX motor on the back and getting the rear wheel set up for belt drive. Also I am not sure where to order the belt.
This build will take some time and I will need more experienced help to accomplish it. Thanks for posting.

Magic? More like it is just BS. It's a phony video or is it magic?
Maybe it's not BS, I think I remember seeing it on MARS the last time I was there, So it must be real!

Then why not investigate it to find out. I know they will soon be selling cars that drive themselves.

They also have those self balancing skateboards. I would really like to know if it is fake or not and the physics behind such technology.

Someone questioned whether it would be a sport to race bikes without riders.

It would be like the robot fights and RC racing. Both of which are popular. I think it would be great sitting on the sideline with a remote control doing that.

You still have to build the bike and hook up everything. Then enter it in the race. Why not is what I say. All is needed is enough people interested.

If I get my van on the road would you be willing to give me a hand installing the FX motor and controller. Also do you know of a race track around your neck of the woods where we could try it out and video it for the forum.

I am not hooking it up to a cheap wall mart mountain bike. I am starting with a 125 cc dirt bike frame and going from there and hopefully building something very similar to the original death bike. Also I am sick and tired of working on e bikes by myself. It is why I have been doing less and less as time goes on. And playing Pirates more and more. Also the shitty weather plays a factor

However I have e bike projects on top of e bike projects to do. All is needed to get my dual motor 20" bike rolling is the chain. However it is a set back as I can't even break #25 chain.
I have been looking on e bay at #25 chain breakers. I have ordered at least 3 or 4 and a couple of them broke like the first time I used it.

I do not want another cheap one but is all I see.
Also the FX motor if my dream RACE BIKE. For racing only and since I am 51 years old I will never again have the opportunity to fulfill my dream which started in the mid 1980s and that is drag racing. I went with my friend bob in the 1990s to Lebanon valley speedway when he raced his big block mopars, but I never raced. Therefore this FX motor is my dream to actually be in a real SPORT.

It is separate and the next level from e bikes as a hobby. As far as a hobby goes I am finishing the 20" bike and installing the alien power motor I will be ordering on the Haro V3. My dream STREET BIKE.

IF anyone asks why I have a 60 HP motor and controller sitting on a shelf and am building other bikes then the answer should be obvious. Because Latecurtis needs a hand with that. It is not something I can just slap together on a Sunday afternoon. It requires careful planning plus the correct tools and parts. Furthermore if anyone has a question why I am building other bikes then they can answer this. Where do I order the belt for the motor. It is belt drive and if anyone thinks I am dumb enough to try to change that and possibly damage a $5,000 motor it is NOT happening.

Also what type of rear wheel will I need and how do I set up the wheel for belt drive ? When someone can answer those questions and are willing to give me some hands on help then they can ask why is latecurtis working on his other e bikes and not building a bike for the FX motor. I am still nervous about charging 6S LiPo. Imagine me hooking up the 90 volts or so required for the FX motor. There are a ton of questions to be answered and a long list of parts and also welding equipment required to do the FX project I shall call it and do it right,

Until then I will do hours of research and post regularity here to try to find someone who is willing to physically help me out but until then I will be building other e bikes and riding some of the finished bikes I have like the Schwinn and Diamond Back with the hub motors. Thanks for posting.

LC out.

The pictures are of the #25 chain. I have been trying for a half an hour just to get the clip off the master link.
It don't even look like I have the mechanical skills to do that.
I need to break the chain and measure it for the wheel and motor sprocket and possibly find a place that works on scooters or mopeds to put it back together at the correct length.

OK I managed to get it. I thought I lost the little clip but it showed up. Now I will need to break it again at the correct length and get it back together without a chain breaker tool

I got it back together but what I figured would go wrong did. Notice the pic fourth down from the top ; the little clip at the end of the arrow I drew. Yep you guessed it. It flew away attempting to get it on there and is nowhere to be found. This has happened so many times before. (click on pic and it gets bigger) It is one of the reasons I hate thin chain.

Now I will have to wait for the new order I placed. I need the bullets to combine the other two LiPo packs Dan sent. I also ordered extra chain and master links. The dual motors on the back of the little 20" bike will be fun as hell when the weather breaks and spring comes. There is no way it will be geared too high with two wheels spinning. Total power is 1,033W at 24V and 1,550W at 36V if I choose to run it at that. Thanks.

[latecurtis]

I might buy it if anyone thinks it could work for the FX motor.

I like the style. It looks more like a bike than a motorcycle.

If I do but a dirt bike frame I am stripping all the plastic off of it.

Ok. I got it.

Lets see if I have learned anything here on this forum. DA said something about giving up.

Lets see if I can pass the test.

If I were to choose between these three my choice would clearly be the bottom. If I had that bike with the FX motor I would put it in my will to be buried with it.
That bike is GORGEOUS

That is my choice and the owner is on this forum.

The only thing that could stop me is the price tag. That will probably make me cry.
However I am giving up on anything less for that motor and say if I get it built in three to five years and I survive 10 years or longer there will be a 40 HP peak motor on the front also.


Thanks.

[latecurtis]

I may have to order the parts separate as for the price this is not bad.

I said I was doing research and I am.

I am looking for deals on parts for the FX project

I want to start with a frame and go from there. I am looking for the best or strongest parts for the least price.

I am experienced enough to finish the two remaining e bike projects for the street and every day e biking myself.

The dual motor 20" bike only needs a little clip for the chain which I get in about a week and Bruno from Alien power will help me with a 24V controller for
2400W and 40 mph street ride. I wont need help from here on those projects but will still post videos as the Haro V3 will be my first professional build.

The FX project however I could use some advice on what parts to choose which will be the strongest and safest for the lowest price possible.
basically dirt bike parts and frames.

I am willing to go with the heavy duty dirt bike frames but want it to look as much like a mountain bike as possible. NO plastic panels or anything of the sort.

Thanks again. Please let me know if any ideas , name brands or whatever.

Again the bottom picture looks like the best deal as shipping is free.

The physics you refer to is mostly gyroscopic forces: http://www.cleonis.nl/physics/phys256/gyroscope_physics.php

However, they've since discovered (2011) that it's not actually sufficient to keep a bike upright by itself. From what other experiments they've done, by changing particular ratios on bikes, that certain ratios (e.g. angle between fork and body, etc) help keep the bike upright better. So in some ways the first bikes were "self-balancing" by coincidence of design.

The sports you mention have a human behind remote controls, so it is still a game of skill, if not truly a sport. But even computer gaming is considered an eSport, and you can be fat, old and still be the world's top golfer, so I'm not challenging you on that one. But with NOBODY involved at all, except a programmer who might not even know the game is being played? I think you're stretching it.

On the other hand, they have robot soccer COMPETITIONS:

[youtube]otsQL4SFxX0[/youtube]

Those guys behind the computers aren't remote controlling them. Those robots are programmed before they enter the field, and their owners have no control over their actions. That's not a sport though, that's considered an academic pursuit - somewhat like programming the best chess computers.

 

[latecurtis]

Ok thanks Sunder.

Did you get a chance to look at the dirt bike frames I posted for the FX motor.

I have decided to get a frame and rear wheel that I will need for the FX motor FIRST before ordering the Alien power motor for the Haro V3.

Basically I have everything I need here or it is ordered for the little 20" bike with the dual motors including 10 master links and 3 feet of extra chain.

I even have the thumb throttle so I wont need to order any more parts for that. Also since the weather is so horrible right not I see no sense in rushing into the Haro V3 project as it can wait until March or April.

however since I am going to need wheels , shocks and tires ect. I would like to at least order the frame THIS month and maybe the front forks if I have the money for the FX project.

Also the thing DA mentioned about me trolling by saying I want a 40 HP motor on the front also is true if I were talking about mountain bike forks but I am ordering heavy duty dirt bike forks.
There is no way I will be putting a 40 HP motor on the front for at least two years though as I need to get it running with the FX motor on the back first however I do not want to have to upgrade the forks in two years if I do that so I want to order good enough forks and shocks now. I am looking for the best and strongest parts for the lowest possible price. Thanks.

As The Hub Motor Turns and the LiPo Fire Burns 20 mph
30 mph
40 mph
50 mph
80 mph
100 mph


We shall start our new series of videos with the dual motor soon to be the next finished e bike project as I got all the parts and extra chain and am ready to finish it all up and do a video.

@ 24V and approx. 500W going to each motor not only will the poor gearing no longer be of any concern with both wheels getting power but it should fly up hills with no problem as 1,000W+

with 20 mph gearing.

@36V the same gearing will easily propel the bike to 30 mph at approx. 1550W total power or approx. 1 HP for each wheel

@48V The same gearing, 40 mph is possible but I would NOT DO THAT on a 20" kids bike and NO I am not TROLLING anymore. That is common sense.

40 mph will be achieved by a custom Alien powered e bike which will have custom KV running 24V to a custom controller all at no extra cost and that came directly from Bruno at Alien power systems. I already posted the conversations. The front of the Haro has DISK BRAKES. The rear wheel will be set up for disk brakes but will get TOP QUALITY U BRAKES as the wheel sprocket will bolt directly to the disk brake set up and gearing will be set for approx. 40 mph running 2,400W. It will be my first professional build.

For faster than 40 mph speeds a mountain bike frame will not even be an option. I will most likely never travel 50 mph on a mountain bicycle frame. I will need to build an equal version of the deathbike which we all know is a hybrid motorcycle front end with dual disk brakes on the front. I may however just use an entire dirt bike frame and just make it an electric dirt bike. It all depends on what welding equipment and the skill set available or person to help weld as I do not know how to weld.

What I do know however is that I will have $$$$$$$ to finance the FX project this summer. There has been an increase of income coming in to the household and I have TWO vehicles sitting in the back yard. A 1993 Pontiac and a 2005 Dodge Caravan. The Van is in top running condition and was drove here. The Pontiac was from next door and needs master cylinder and fuel / brake lines.

My plan is to trade the Pontiac for a 125 cc dirt bike in good condition except for a blown up gas motor. It should be an easy trade as I can fix the gas line at least and get it started as the motor runs great and the tranny is new with only about 35k on it. I may fix the car up and get it running good and trade it for a dirt bike with a blown gas motor plus two or $300 in cash which I can use towards batteries for the FX project. Either way the FX project WILL HAPPEN this summer.

Also the dirt bike front end may be from a 250 cc bike if it is stronger than a 125 cc bike. I think that a 40 HP front hub motor will significantly add a huge safety factor to the build.
I saw a video where a bike flipped backwards as the front end shot straight up like a rocket and it was like 8 or 10 kilowatts. Not even close to the FX motor.

With two throttles, one on the right for the front motor and the FX motor on the left the bike will basically be a two speed.
The heavy duty hub motor will add about 30 pounds or more to the front wheel.

normal driving conditions 0 to 50 mph front hub motor. 50 to 70 or 80 mph both motors if passing a vehicle but letting off the right throttle after for top speed as the hub motor should be geared for 50 to 60 mph and the rear FX motor for 90 to 100 mph.

Racing from 0 to 30 mph front motor then both motors so bike does not flip. 2 stroke dirt bikes and four wheedlers will probably have their front wheels off the ground for a few feet and may enjoy a very brief lead until the FX motor (my second gear) kicks in and I go from 30 to 90 mph in 3 or 4 seconds and blow by anything gas awhile they are going from third to fourth or fourth to fifth depending how many gears they are running.

Thanks.

All sounds good, except I'm not sure you've done the maths for the power required at each speed.

50mph is about 6.5-8.5 kilowatts, depending on even the slightest gradients, and even which way the wind was blowing. This morning I was very surprised to to be only 6.5kw UP a very slight incline at 50mph, because I had a fairly decent tail wind. That tells me however, 8.5kwh or more would be easily hit had I been doing the same into a head wind.

Let's just say an average of 7kw, you're looking at 300A @ 24v, 200A @36v and 150A at 48v. The first is probably non feasible. The last two will require very expensive controllers, as well as cables and connectors. Get over your fear of high voltages (After learning proper respect of them of course). You need a much higher voltage system to be able to realistically go those speeds.

Oh, and I hit 75mph for the first time today. Went to visit a client who was 40km away, so used the freeway. It was a good stress test of the battery. Held up very well, both power and range, but wow. Using regen from 70mph, I was getting some very serious feedback current. Was worried I damaged my cells, since they are designed for 10C discharge (which I don't hit), but only 2C recharge, which I went WAY over for about 2 seconds.

I am not sure what the FX motor is but think it said 96V.

I have the controller for it. I don't know the current limit.

I will check but 6 - 20.0 - 6S packs in parallel series should work. 40 AH or 66.6V minimum or 4.175 * 18 = 75.15V .

That would make sense for the FX motor.

Might be able to get by with three 20.0 in series for the front hub motor.

Rear motor = 50 HP

Front motor = 30 HP

That I think is what the FX motor I got

and an approx to the 40 HP peak motor DA posted 4 U.

I agree that low voltage wont work for the FX project.

However the FX project is for summer. It is winter.

The Haro V3 however will run off of 6S LiPo for 2400W via custom ordered Alien powered parts.

This will happen after the video for the dual motor 20" bike comming up soon on

As the Hub Motor Turns and the LiPo Fire Burns.

What da hey ...
One more shot into the dark ... whatever ...

#1 "One on the bottom" trail bike is a Mongoose CX 450. Runs on a .6hp motor.
A 6hp motor would probably rip it apart ... and you wanna put a 60hp motor on it?
10,000% its designed motor???

#2 Front hub motor
Apparently you didn't learn anything from your 800w front hub motor that was too dangerous-unstable to let anyone else run.
Yes it will easily spin out and dump you on the street ...
Well, your 800w eBike had maybe 80lb(?) on the front wheel.
You think the 30lb weight of the 30hp (22,500w) motor will hold it down!
That would be ~110lb on the front tire so ... 1100w motor would be just as dangerous!
You should realize that any acceleration lifts weight off the front wheel letting it spin and slide all over.
The best you could hope for is to dump it before you get to more dangerous speed!

#3 Motorcycle parts
Motorcycle parts are not typically interchangeable!
So you would have to buy separate parts from the same make and model and similar year motorcycle ... if you want them to fit together

#4 Donor Motorcycle
Well a 125cc dirt bike might handle a 10hp motor OK ...
But if you want to run a 60hp motor you want a motorcycle designed to handle that much power!
Some where in the neighborhood of a 500cc.

#5 Motorcycle Suspension fork
Motorcycle forks are not designed for a pulling stress!
While they are capable of maybe 1000lb compression, they are only designed on extension to retain the weight of the wheel.
Much of any power at all will likely rip the forks right off, or apart.

 

[DAND214]

Without quoting DA's post. I agree.
DA has spent a lot of time with you, trying to stop your suicide rides AND I agree with him! If we didn't see pics and videos, we wouldn't even believe yo,. like Swbluto's living in a forest. he won't even post pics.

Why don't you just send that back to Luke and ask what it will cost to trade for the parts he sent in exchange for the Deathbike

I would like to study the stress on the front end geometry of dirt bikes during these helliatus jumps.

The landings are mostly compression stress and not pulling stress as was mentioned ?

Either way I would like to do some research on which components commonly fail during that sport where bikes land from high altitudes.

I would also like to know how many road bikes fail when hitting large potholes and other road obstructions during high speed before I put myself on a 40+ horsepower bike.

My main concern would be the structural integrity of the goose neck which holds the forks into place. It would seem that it would be the strong or weak link in compression AND pulling stress.

The bottom picture shows the two very extreme possible landings. Obviously the vertical nose dive landing would be an epic and tragic FAIL , however the horizontal landing to end such a jump would be considered perfect.

I would guess that the majority of landings would be somewhere in between the two and by looking or guessing the front end geometry would need to be able to handle extreme stress in BOTH directions as depending on the landing the force on the top of the forks or the goose-neck could be in EITHER direction as the arrows show. That is why further research is required to find out at which direction of force is the usual culprit in a catastrophic front end fail.

For now though I want to finish up the current 20" bike build and also accomplish my first professional build. The Alien powered Haro V3. Thanks for posting and I am listening and trying not to do the trolling thing.

Let's demonstrate-test acceleration (motor) and deceleration (brakes) of front vs rear wheels.

While pushing bike forward apply rear brakes to lock up.
This demonstrates rear brake only effectiveness. Should drag fairly easily = rear brake only has poor stopping traction.

While pulling bike backward apply rear brakes to lock up.
This demonstrates rear motor acceleration. Should be nearly impossible to pull, even with almost no weight = rear motor has excellent acceleration traction.

While pushing bike forward apply front brakes to lock up.
This demonstrates front brake only effectiveness. Should be nearly impossible to push, even with almost no weight = front brake only has excellent stopping traction.

While pulling bike backward apply front brakes to lock up.
This demonstrates front motor acceleration. Should drag fairly easily = front motor has poor acceleration traction.

 

[latecurtis]

OK.

So what you are saying is to stick with a single rear motor to run the rear wheel and forget about a powerful hub motor for the front when I get a dirt bike frame for the FX motor.
It makes sense as I have never saw a big hub motor on the front of any motorcycle and I did research it.

Right now I am attempting to solder again.
I am finishing up the dual motor project on the 20" bike.

Those plugs are what both 24V controllers will plug into so I can run both front and rear motors with a single thumb throttle.

Obviously I still cant solder. I am taking a short nap then going to Wall-Mart to get some colored electrical tape to tape r up. :lol: :lol:

No, actually, that is not what I am saying!

I have said that a dozen times and you won't listen or just can't comprehend ...

What I am doing is providing you with a simple test that will let your genious mind see for itself that a powerful front drive is at worst dangerous and at best ... just useless.

 

[latecurtis]

I slept too late to make Wall-Mart. Tomorrow is another day.

Yes It makes sense. The traction is where the weight is. I just hope that the dirt bike with the FX motor on the back will not flip over. It will be a challenge keeping the front wheel on the ground with all that torque going to the rear wheel.

https://www.youtube.com/watch?v=hsnkD10yklc

That video is why I was thinking about a front hub motor.

The controller that was sent for the motor is programmable. However it is beyond my skills.

You would think that with self balancing bikes they could come up with a controller which would cut power to the back wheel when a sensor tells it that the front wheel is lifting up.

I will get the dirt bike frame and mount the motor but was wondering if I could get some help hooking up the batteries and controller.

My 2005 Dodge Caravan will be on the road this summer and I can drive to where you are in about 5 hours I think.

Would you help me so I do not electrocute myself. Also the belt drive on the motor. I do not know where I can get a rear wheel to complete that set up. Also where would I order such a belt.

Thanks. LC out.

You would think that with self balancing bikes they could come up with a controller which would cut power to the back wheel when a sensor tells it that the front wheel is lifting up.

On first glance, that might look pretty easy. But think it through, how would you know the wheel was off the ground - and more importantly, why?

E.g.

1. Front shocks decompress - you could be going over a jump
2. Front wheel and back wheel have very different RPMs - you could have lost traction
3. Angle of bike - you could be going up a hill.

(2.) would be the closest you could get, since if you've lost traction, you probably want to lower the power output anyway, but that' might not be 100% true - You could also have for example, gotten a bit of air in that case too.

Things always seem simple until you try to think through all the scenarios that could occur.

LC, you will be able to tame the throttle to a soft start when you learn how to program it. I am sure Luke can help you do it.
