new eZip motor

[latecurtis]

Ok.

What about alibaba though. Did you check out some of the prices on their hub motors. I cant find a contact number from them though. it is very frustrating.

That 2killowatt 24V 2900 rpm motor is exactly what I need. Please let me know.

 

[Sunder]

Alibaba is for wholesalers. But anyone can buy from them as long as you buy the minimum quantity. If you are just buying one, use Aliexpress. Most manufacturers list on both anyway.

By the way, I don't need a PM every time you post. I check when I have time, and sending me a PM will not make me check any faster

 

[latecurtis]

ok thanks.
I tried to join alibaba but they sent something to my e mail but i could not find it.

I will try the other one hopefully it will work

If I have trouble mabye I could send you my e mail and you could set it up. I want to order that 2 killowatt motor instead of the winch motor. thanks.

Probably went to your junk filter.

No point giving me access to your email. If its not working for you, it won't work for me.

I guess you didn't look at the output shaft.
THERE ISN'T ANY. It looks shorter than the mounting flange.

Ok Now I am asking DA this as he posted this motor originally. Is there a way to put a motor sprocket on this motor ?

It really does NOT make much sense in posting a motor if you cant put a sprocket on it.

Also I was definitely going to order it but no sense if I don't have a link for whatever is needed to put an 11 tooth motor sprocket #415 bicycle chain.

Also the best compromise I can think of is the rolls of 4 gauge wire with the 100 amp variable controller and 4S LiPo. It will get me 1670 watts to the motor

4.18 * 4 = 16.72 * 100 amps = 1672W full charge. 3.7 * 4 = 14.8 * 100 = 1470W LiPo as low as I will run them.

2100 / 12 = 175 rpm. 175 * 4.6 = 805 rpm. 2100 + 805 = 2905. 2905 - 105 (under load) = 2800 rpm.

Sprocket calculator states a 72 tooth sprocket will gear it for 37 mph.

Please ! someone please let me know if a motor sprocket for #415 chain will fit on that motor so I don't waste any more time on this. I really need a straight answer and a link for the sprocket type and adapter hardware if needed. Thank you all.

1. Find the size of the keyed shaft.
2. Search for a sprocket with same size shaft compatibility.

This thread is two years old and still being spoon fed!

Both my kids started feeding themselves just after 1!

[DAND214]

Wasn't the shaft size on the spec sheet?
If not, you'll have to measure it, after you get it.

I will look in electric scooter parts and monster scooter parts but dont remember any keyed shaft sprockets.

.4 inches is not even close to 3/4 inch.

I seriously doubt there is a sprocket made for that motor.

I am not sure why DA thinks with a little effort I could find one.

FIND ONE WHERE ?

[latecurtis]

will this work ?

It wont post for some reason. It is way below the 500 kb limit. I even changed it to a jpeg image.

A simple yes or no would be good.

I know I am not as smart as DA or most of you guys.

However I did find this page. I am just not sure what will work and what wont.
I guess I could order another spoke kit and chain if I cant get a sprocket to work with the 56T I am currently working with.
As you know I lost the rubber pieces for the 56T on there now but still managed to install the sprocket with the rest of the parts. I doubt the rubber pieces would fit anyway as I used six bolts instead of the nine as it is a 48 spoke rim and not a 36 spoke rim.
This means that I will need to take it easy on take off and will never be able to short the battery to the motor at 35 to mph to get 50+ mph out of it.
I will be happy with 35 mph for this build.

Thanks.

What are you going to do with a centrifugal clutch? The motor won't even engage it. You are looking at Go-kart chain there. 219 chain is strong roller but small than you are looking for. Ran that years ago with 30hp engines.

You know that there is NFW I would trust the wheel sprocket if it's not fully installed. You will pull the sprocket off center and blow the chain at 50mph and slid all the way to the hospital. :lol: :?

You still can do 30mph, without a chain if you load the parts and batteries on the bike and do the killer down hill ride. Would be safer than the chain installed.

I am not intending on going 50 mph.
I stated that I am good with 35 mph.
There are 6 bolts holding the sprocket on instead of 8

I did not see any 48 spoke sprocket kits anywhere nor did I see any sprocket for that winch motor.

Yea , sure It is easier to just order a hub motor. I already have two hub motors and both bikes are running fine.

I am wanting to do this build because I enjoy building electric bikes. It is why we have a forum. This forum is for people who enjoy building electric bikes.

Anyone can buy a hub motor and hook it up to LiPo batteries. It is NOT difficult to install a hub motor and there are lots of you tube videos on how to properly charge and run LiPo. We dont need a forum for that. The forum is to do unique builds which may be out of the norm and somewhat challenging.

I have in the almost three years built several e bikes which are not common and somewhat unorthodox. Some of them lasted a few days and some a lot longer
however I fail to understand the constant criticism when I am simply experimenting and trying new things.

I am capable of doing this build and see no reason why it cant work and go at least 35 mph but should NOT have to feel like an idiot because I cant find a motor sprocket for a motor someone else posted.

It was a simple question. Does a motor sprocket exist for that winch motor or not ?

Thanks.

15 second google.

A #40 chain will go on a #410 sprocket, but not vice versa. So you will need to upgrade your chain to a #40, and you might have a small amount of play on the #410 sprocket.

Thank you.

I was just reading a long article by spinning magnets waiting for someone to post and I saw that about the #40 chain and now you verified what he was saying.
It must have been less than five minutes ago I read that. Thank you again sunder as That 15T sprocket you posted sent me in the right direction. It took less than five minutes to find the 10T which should work without gear reduction.

In a perfect world or should I say better world I would have spinningmagnets living next door to me and you across the street and the three of us would get togeather every sunday afternoon and work on e bikes :lol: Dan would live around the corner next door to DA and they would come over also and we would have a cookout with hotdogs and hamburgers. :lol: Liveforphysics would show up about once a month with an SUV with a bike rack on the roof and we would all head out for the test track. :lol:

However I live in this world where I am the only one I know for hundreds of miles that builds e bikes. Everyone I know cant put a beer down long enough to fix a wheel on their kids tricycle. :lol: Thanks again.

What you describe wouldn't be too bad, but why do I get the feeling that it won't just be Sunday afternoons that you'd be around, and we'd be hearing swearing and banging at 4am, as you try to line up a motor and chain after a six pack?

That part I could do without

Mr Latecurtis,
Whaat are you doing? Motor, sprocket, chain, 155 pages of electric bicycle projects. If you really believe the your way of building a electric bicycle is the best way to accomplish your goals, then carry on. My suggestion to you. STOP. Rethink. Would you like a reliable electric bicycle to transport a human from one place to another? Read, ask questions, start a new topic.

How to get the proper advice, read before asking

To get solid advice on parts to buy, you must provide the following info.
Desired max speed on level ground. mph or kph
Desired max range at what cruising speed. mph or kph
Preferred bike wheel size, or wheel size of bike you want to convert. Most common kits are for 26" wheels.
Brake type of motor wheel. Disc or not.
Rider weight.
Terrain. Exp: mostly flat, some short hills under 20% grade, I want to climb mountains, etc., etc.
Budget.

Me...... I don't agree with any of this. With just about anything, I say don't build it. Buy it. Buy a ready made electric bicycle. Comes to your house in a box and all you have to do is put it together.

Yeah, I don't either. I could make a boat out of lead foil too. It'd probably still float, but you know, I wouldn't be doing it because it was the best way to do it.

It's his hobby, leave him to it.

I agree to a point, hobby? I think it's more an addiction

[latecurtis]

yea. The thing is though I have fun experimenting.

I wish I had the mechanical skills to do a brush less high output motor from Hobby king or something like Skalabala did about a year ago but I still have a lot to learn before taking on a complicated jackshaft gear reduction project like spinningmagnets.

I have all the information needed now to build this thing. All I need now is cash and a new paypal account.

I also have three reliable bikes already built. I guess I will need to post new videos with them as members keep forgetting that these bikes do in fact work and are not failures.

I will be building a forth e bike with the 500 watt motor on the handlebars before I build the 29" bike with the winch motor as the bike is on the back porch. The one that had the 2 by 4 deal. That lasted for several months I believe before the motor sprocket got wore down because it was not perfectly aligned. It was a semi successful build.

This time though it will be just as reliable as the 24" cargo build is now. The only thing is I will only be able to ride a front wheel powered bike on good roads. The 24" bike has the motor on the back will need a studded tire on the back in case I have to ride it in bad weather.

Thanks again to everyone. I should have the 20" bike on the back porch up and running soon.

4.18 * 4 = 16.72 * 100 amps = 1672W full charge. 3.7 * 4 = 14.8 * 100 = 1470W LiPo as low as I will run them.

2100 / 12 = 175 rpm. 175 * 4.6 = 805 rpm. 2100 + 805 = 2905. 2905 - 105 (under load) = 2800 rpm.


16.72V * 120 amps (miminum) = 2,006.4 watts (minimum)

16.72V * 200 amps (maximum) for 1 minute = 3,344 watts (maximum)


Basically if this kelly controller works gearing will be for 47 mph with the current 56 tooth spoke sprocket already on the 29" wheel.

With the 100 amp variable controller power would be limited to 1672W causing it to be over-geared by at least 10 mph.
A 70 tooth spoke kit from Kings custom sprockets will be at least $100 with shipping so for less than $100 more I get the Kelly controller which is a higher quality controller with more features.

Please let me know if the Kelly controller would work and if anyone knows of a better deal to save money like a 150 amp to 200 amp controller which will run 14 to 17V cheaper. Or a 300 to 400 amp controller for 14 to 17V so I can get over 4 killowatts out of the motor please let me know. Thanks.

I guess the message about not PMing for every post didn't get through. I get the email notification to my work email, and it pings my phone when you do that, which, considering time zone differences isn't always at a good time.

What do I have to do to get a little respect around here? Ignore your post if you PM me early in the morning about it? How about I try that now? Instead of answering your post, which is a very quick and simple answer, I'll just complain about you harassing me. Maybe Dan or DA will give you a good answer instead.
