new eZip motor

[latecurtis]

I charged them to 4.2V a little over three weeks ago at the other place. The Schwinn is still hooked up with alligator clips.
I was going to solder some bullets but did not get a chance since I moved.

Also I have not found my pre hook up cable as well as the Mega charger you sent. I dont think anyone would steal it as nobody I know is even smart enough to use it. I will look for it tomorrow. I could probably go about two miles maybe with them. I dont think downtown will happen though. They would make it down ok but probably not back as it is mostly uphill.

I can run the SLAs for downtown runs. The steep hill is only about three and a half blocks or so or less than a quarter mile, then there is a gradual incline. DA would probably state otherwise but I dont see how one short fairly steep hill would kill the SLA batteries with a little pedal assist. Also 10 to 12mph on the flat should be less than 1C discharge.

The two original SLAs that came with the Currie were abused relentlessly from the time they were broke in and ran until totally dead three times right up till the end of the 6 months they survived running constantly at full throttle and even pulling large grocery carts full of scrap metal.

10mph on flat and pedal assist on moderate hills, four 10Ah SLAs should last two years. I should get about 200 50% charges at least as I know that 48V@10AH doing less than 5 mile runs (no full throttle) except for up hill should be about 50% or less capacity. Utilizing the old LiPo packs for short runs up to two miles should give me a years to 18 months worth of battery life for the Schwinn with no problem.

Full throttle is dangerous for the Schwinn anyway as it is a front hub motor. 10 to 12 mph on flat and 15 to 18 on slight decline I can live with for now. When I get the other 10.0 6S pack I will have a 30 mph capable bike in the 24" Huffy bike with the 20" wheel and 65T spoke kit and the 24" front wheel I found today out in the garage.

That is about as ambitious as I am going to get this summer I think as I would like to fix up my car for the fall and winter for when it is too cold and too much snow to ride an e bike. Thanks again for posting.

As the Hub Motor Turns and the LiPo Fire Burns. Who cares if it's a little heavy now. How fast does it go?

I have to sit back here and think. Also missing are two of the new SLAs for six total. I hope I can find them because finding the 24" tire today was great but with 6 SLAs and that second controller in that white package the 24" bike could run just as good as the Currie did. 750 or 1 HP is a sweet spot with e bikes.

500W will get you around up to 18 mph and struggle up hills. 750W will do 23 mph and walk up those hills.
The king of the hills of course is the Diamond Back. It is a 20" kids bike though as DA would say.

Problematic to say the least with the shaking vibration and super touchy throttle. Bearings? maybe.
SLAs being too much weight on an already overloaded bike when i mount it? definitely.

Good reliable transportation? maybe but not with SLAs. I need to paint the rear wood box black and add a lid that locks and perfect for two 10.0 6S packs. I refuse to run that little bike with SLAs. Too much weight and unsafe. The other 20" bike is safer at 533W geared for flat.

The bike I got running today, I mounted the motor with a 2 by 4. I took two trips earlier on the flat. It cruises about 18 mph at least. The Diamond Back may do 19 mph and a hell of a lot quicker but if I am drunk and hit the throttle too quick I could lose my front wheel and get seriously injured. The brakes are about the same. Both functional but leaving much to be desired.

The Schwinn is the best bike and The 24" Huffy with a 24" front tire and good front brakes at 36V and 750W just makes the most sense now for the next build. Thanks.

Running an eBike geared for 30mph ± at 10mph puts the motor-battery in an inefficient, damaging region of their performance curves with pitiful acceleration and hill climbing ability!

I reiterate my recommendation for the < $100 kit gear reduction motor w/spoke mount sprocket! For rear wheel mount!!!
Cheap easy gear swapping for <10mph to >20mph.
Voltage options for various speeds and torques:
22.2V 325w ≤ 19mph
24.0V 350w ≤ 21mph
33.3V 485w ≤ 23mph
36.0V 525w ≤ 24mph
44.4V 650w ≤ 27mph
etc.

You must gear for lower than maximum speed or acceleration and hill climbing ability will be pitiful to lackluster!

 

[latecurtis]

I may never be as good with these graphs as DA.
You have convinced me that that 350W motor would do the trick. The thing is though i am out of money for this month.
What I must do is make the best at what I have to work with. I understand when riding my 20" bike how important gearing is.
It will climb hills that are slight incline but really crap out on anything a little steep.

The Schwinn tops out at about 25 to 27 mph I believe and is a little better up hills than the 20" bike.
What you are stating is that running the Schwinn 10 mph would be no good for the 48V SLAs or the motor.
What about 15 to 18 mph ? That would be about half throttle not full throttle. I know full throttle especially up hills without pedal assist will push the SLAs beyond 2C discharge when 1C or less is the target. That is question #1.

Question #2 is what I plan to do for a back up for my 20" bike simply because i dont have to order anything or spend any money.

Current gear ratio for 20" bike.

2750 rpm@36V. 2750 / 3 = 916

2750 - 916 = 1834@24V

1834 rpm

20" wheel

20 mph

ratio 5.458 * 11 = 60.038.

That is the specs for my current 20" build with the 11T motor and 60T spoke kit.
good on flat but only works for small to moderate hills.

That and it will be a chance to improve my mechanical skills building e bikes.

specs for 24V 500W motor. next 20" build
From page 71 sprocket calculator.

rpm - 2,500

tire in " 20

speed mph 16

ratio 9.301 * 9 = approx. 81

Basically the 24V 500W motor I already own teamed up with the #25 80T sprocket which bolts to the freewheel and the #25 9T sprocket I got brand new from electric scooter parts should work on a 20" bike.

This is also a chance to prove the importance of proper gearing as if I get another rider about the same size as me I can shoot a video of the bikes accelerating side by side on flat and up a moderate hill and post it here with all the specs.

Question #2. If assembled, how would it compare on that graph to the 350W motor at 22.2V or 6S LiPo?

When I do get the money I will order that 350W kit just to see how it will do against my 20" builds in a race.

Thanks. LC. out.

As the Hub Motor Turns and the LiPo Fire Burns. 36V 20Ah SLAs ?


I really need to find those other two SLAs today. I just remembered that the Schwinn will run off 36V. Not only that but with the new variable controller with the pot like the one on the 20" bike I could run the 24" bike with the 24" wheel on the front and 20" wheel on the back. currently over geared at 48V and 35mph.

At 36V and 2250 rpm gearing will be perfect. Gearing will be for 26 mph at 750W@36V. I am hunting now for the other two SLAs and the Megacharger and the pre hook up cable.

pre cable found. 50 foot heavy dutu cord found. Going to pizza shop then back for more treasure hunting. lol

Found the other two SLAs under the back seat of the car. Close to 13V each.

Got to go to Wall-Mart. no electrical tape, no gorilla tape, no zip ties, no electricity if I dont send money on the bill. Still no Megacharger. later.

Thanks.

did three videos with the 20" bike. the first was mostly downhill to wall- mart. the second in wall mart parking lot and then back up the hill to home. The hills were not too long or too steep but were still hille. this is the 533W 24V bike geared for 20mph

did not know. spent 3 hours now posting it youtube upload takes about 1 min for every 1%
ridecelous

It says public and I hit share. Try it again. I am uploading the last one.

uploading the one going back up hill. It says public. Also got 7 views on the first.

It shows that the bike is ok up small hills not great like the Dimond Back but running good. Hopefully you can watch it.

[latecurtis]

Just tried the last one and got private but tried again and it played. It says public when I publish it.

My friend just played it on his phone. He typed in latecurtis and it came up.

I tried it again also. If you can see it go to the first video and notice the hill I coasted down. That was the hill i came up on but had a bit of speed going into it. . I am not sure if it would make it from a dead stop. The Diamond Back did in an earlier video and was over 10 mph probably close to 15 mph and accelerating when it hit the top.

I know the deal on gearing and not interested in a slower 20" bike. I will work on the 24" bike now and maybe ride the Schwinn
if I can get 36V@20AH with the SLAs.

I will probably order the 900W monster scooter kit before ordering more 6s LiPo for 44.4V. Thanks.

Sorry, that link didn't work either. I can see by the URL though, it's got an edit command in it - and again, since I'm not you, I DEFINITELY won't have permissions to edit your videos.

 

[DAND214]

More MOTORS! I think you need to get them power before you get nore MOTORS.
It's supposed to be more POWER!

There are lot of mv1153-154-156 videos. Do you have a channel your videos are? I still haven't the DiamondBack ride. Want to see how a powered bike should climb that small hill.

I did two videos of the Dimond Back awhile back. One was really shaky and the other blurry.

I would do another one but what is the sense if nobody can watch it.

It says public and one of the videos has 21 hits. the other 20 and the one comming back I hit publish so hopefully it will work.

If not then I guess it is time to retire or go back to shooting those crappy < 512 kb clips. :x Thanks.

top of page 136 shows the Dimond Back doing 10 to 12 mph at the top of the hill from a dead stop towards the bottom. It did not come in clear. i deleted tho other one which looked like i was going over a million speed bumps.

I am working with a laptop. The desktop has no internet connection I dont have the software drivers for the internet adapter.

I failed to change my paypal info or my e bay info to my current address so not only are videos impossible but also ordering anything from now on.

It may be a much better apartment but now that I have all the room to work on e bikes i suffer from other limitations.
I can only make use of what I have here now, only pictures and short < 513 kb clips. thanks.

LC, I don't know why I am bothering to post this, since I know you're too stubborn to listen. Either I'm too stubborn, or too optimistic too, but here goes: I was reading a book on self leadership last night. What is self leadership? It's about not letting circumstances and other people run your agenda - It's about leading yourself to where YOU want to go. That means that if there are problems that affect you, YOU need to solve them. That could mean asking for help, keeping on trying, or even accepting that the cost of fixing the problem is higher than the benefit of having the problem fixed. The only thing it doesn't include is tolerating limitations and whining about them.

You've lived a hell of a lot more life than me. But I get the feeling you've lived a life that was driven by someone else. Someone else that made you angry, someone else that locked you up, situations that made it hard for you to work. Let me be blunt with you. If humanity is ever going to reach immortality like in your signature, it's not likely going to be in your lifetime - or even mine. Based on your age, you might have 20 years left, or based on your health, you might only have 1. However long you have left though, you can choose to live your life, or you can be a passenger for the other people to tell you how to live what's left.

Thanks Sunder for sharing that. As you were posting it I was outside for a good hour searching the garage and the van for the Megacharger.

My friend Eric is painting the back stairs and porch for money off his rent so I needed to move a broken up box full of clothes and stuff and low and behold what showed up on the bottom of everything. Thanks again.

ps. I changed my papal address and then my e bay address so I should be good to go. Thanks Sunder.

I still don't really have money to spend however am thinking about 36V@20AH SLA. The two SLAs I found behind the back seat of the car will be charged tomorrow. The first was on overnight last night on the three stage 12V SLA charger.

I switched them today and the second one will be done tomorrow afternoon. My question at this time is What is the easiest way to hook up run and charge six 10AH SLAs for 36V@20AH. Obviously alligator clips are out of the question and those connectors which fit on the battery terminals tend to slip off.

I dont have a three stage 36V SLA charger and cant afford it. Also the Mega charger is capable of charging all six in parallel however I will need better connectors as I dont need them slipping off and causing a short.

If they were your SLAs and you wanted to run and charge them the safest and easiest possible way and could not afford a 36V SLA charger but had the mega charger with the 500W power supply and the 12V 1.8A three stage charger I am charging with now and two bikes you wanted to run at 36V ,How would you configure the connectors for switching back and forth?

Also I have not tried it but if the Diamond Back will run off of 36V I will have three bikes to run with the 36V 20AH SLAs.
The Schwinn with the front kit runs 36, 44.4 or 48V. so the Diamond Back may as well. Please let me know. I will be looking for my soldering equipment tomorrow because I have a feeling that whatever idea you guys come up with I will need to do some soldering. Thanks and please let me know.

Have a parallel cable and a series cable.

Series for use.

Parallel for charging.

But... I wouldn't use SLA to start off with, and I definitely wouldn't be buying any more.

If LiPo scares you, could you save up and get a professionally built, BMS balanced, 18650 based Li-ion battery? Almost impossible to kill, and probably the second safest Lithium chemistry there is. Not cheap, but it's cheaper to buy well once, than buy cheap many times.

I dont ever plan on buying SLA again. I can charge and run LiPo. I charged them tonight after another run.

I tested the pre hook up cable before using it with an SLA and the multi meter for continuity.

If LiPo scares you,

it makes me a little nervous but the pre hook up cable helps a great deal. I used it with the cash box and ice cube tray setup many times to do the series hook up. . My attraction to 22.2V vs 44.4V stems solely on the fact that I dont really have money for another 10.0 6S pack right now. Also i dont feel like spending $80 at Kings Custom sprockets for a 65 tooth to run the 24" bike. $150 for 44.4V

With two 6S chargers I could easily charge each pack with a charger for 44.4V and use the pre hook up for all connections but it would still be twice the work hooking up as one 6S and a single 6S charger and how much faster would the 24" bike be at 44.4V LiPo than the Currie with the 900W Monster Scooter motor at 22.2V 6S LiPo.

You already know I will be ordering the 900W 24V kit. It should not be a surprise either that I will get the second 10.0AH 6S pack for 44.4V and the 65T spoke from Kings all by the end of the summer.

However until i feel like spending all that money I got 36V@20AH to play around with and at LEAST two bikes to hook them up to.

i also think i should use the 44.4V setup of Dans to power the Diamond Back soon for a video. But if nobody can see it what is the sense? I know if I get the Fios connection and back to my desktop where my you tube settings are i should be good. Monday the 13th. Until then I would be wasting my time. Thanks for posting.

As The Hub Motor Turns And The LiPo Fire Burns.

The 20" bike seems to be holding up well as a cargo bike. Since I replaced the 40amp with an 80amp fuse about 6 weeks ago I have not had any more blown fuses going up hills.

I could make three or four trips to Wall-Mart or the grocery store but usually recharge at 3.84V on average. 16Ah @ 22,2V is much better than 8Ah at 22.2V

If I did NOT learn anything here than I would be using the two 8.0 6S packs for 44.4V instead of 22.2V and 16AH.
I am willing to waite for a second 10.0 6S pack before running 44.4V but could run Dans old packs for a short distance but am not going thru all the trouble to switch over to bullets. I ran them about two years with gater clips so may as well as they are only good for about another 6 months anyway.

I realize now why I took the 24" wheel off the Huffy and put the 20" wheel on the front but never rode it as NO BRAKES!
The bearings are shot in that wheel. I may have decent brakes but BAD BEARINGS. The wheel will need to go to a bike shop for repair and the 20" bike will not make the hills too good comming back from downtown. The hill downtown is about twice as long and just as steep so it will be better using the Schwinn to go to Freemans bridge sports or better yet a bus.

The Schwinn may make it at 36V and 20Ah but not chancing it as low voltage cuttoff could happen comming back up the steep hill. It is a good 5 miles at least one way.

The Currie looks like it could use that 900W motor kit and Sirus put his paw on the front wheel of the Huffy. Bad bearings or not I think he wants to ride it. I made friends with Sirus about 9 years ago when I first met Eric. We lived on Barrett street then and they lived across the street on the second floor. I would go over to see Eric and Sirus would stick his head out the window and if he looked sad I would know that Eric was not home. He is about 80 years old now in dog years but my favorite Pit Bull. I never owned one but am friends with him forever. :lol: Thanks.

I thought the hub kit Sunder gave you was a 36v to begin with. Most 36v controllers are ok with 48v.

Jump in Sunder. Do you still have the link to the hub kit?

LC if you get the gearing closer to the slower end of the deal you would get a lot more mile per AH.
To day I went 16 miles on 4 Ah. I changed from 44v to 66v and what a change. The hub is a slow wind or a low speed gearing as you use. At 44v it was getting 2mp(g)Ah
I sure wouldn't recommend you to do that but 44 or even 36v is better than 24. It does have a nice snap when I plug it in. :lol:
