new eZip motor

[DrkAngel]

Been searching some BMX forums for pro 20" BMX bike cost.
Most notable was:
"Don't expect a $250 bike to be anywhere as strong or durable as a $1000 bike."
"Most essential is full chromoly (chrome-molybdenum steel) construction!" ... "steel" is dangerous ... aluminum alloy is suicidal ...
(Somewhat paraphrased)
Professionals, whose livelihood, and life, depend on their bike spend thousands ...

Seems they rate $69 Walmart bikes as being suicidal ... even for normal riding!

4.20V @ .3A means pack is nowhere near fully charged or balanced!

Read the manual!!!
Do a search for brand - model "manual" for your balance charger.

Cells might be near 4.15V with large differences in voltage.
Cells are not balanced yet!!!

You need to check each cell voltage with nultimeter several minutes after removed from charger.

Once again DA, you are watching what is not being done correctly.

When I fill the car up with GAS, I watch the fuel gauge on the dash. When it gets near full I stop. Why you ask, I don't want it to be Full since it might blow up! I don't trust the gas pump even tho it has a automatic shutoff when the tank is full.

I STILL DON'T KNOW HOW BIG MY TANK IS, BUT AT LEAST IT HASN"T BLOWN UP YET!!!!! :lol: :lol: :lol:

It has been seven hours I think. I feel sick. I need food. I really should stop drinking. It is going to be a lot of work. There really is not very many companies who make 20" hub motors for the front of BMX type bikes. Also I don't know if the bike is Chromoly or not. Doug would definitely know.

http://www.leafbike.com/products/diy-bike-conversion-kit/20-inch-electric-hub-motor-kit/updated-20-inch-48v-1500w-rear-hub-motor-bike-conversion-kit-986.html

I like this one but don't really have the money. Also it looks really heavy. They have 24V motors but only about 250W. 500W is the minimum I am willing to go and I like 24V better than 48V. 36V in out of the question as I don't have 5s Lipo and surely don't want to run SLA att the time.

If someone could please post a link for a 20" Hub motor kit for a 20" bike it would greatly be appreciated. I wont be home most of the day as I have things to do but would like a better option than a chain driven motor on the front. Geared or regular hub motor would work. 24V and 20mph capable without going much over $200. I have not seen much out there. Most hub motors are built into 26" wheels. Another reason why I don't have one. Thanks.

[DrkAngel]

You should really let the balance charger finish its work!

Leave charging till it says complete, another ~1/2 to 1 hour+.

If my packs were that stuck out of balance, I would probably tear them apart and rebuild.
When I balance my packs it is to within a few thousandths of a volt!

 

[latecurtis]

I can later. I want to combine the packs also. When should I do that. The 1500W 20" hub motor looks good but would rather have something 24V. Why I like that Monster scooter kit so much. I don't have to do series connection and it doubles my Amp hours if I go at reasonable speed.

I may have Doug fix the problem with the red bike and get that 1500W motor for the rear wheel later on though. I just don't know about spending that kind of money right now though. Then there is the weight factor.

Another thing is a motor in the front is better for a large cargo basket on the back. The only reason the Currie was able to haul so much stuff was the three heavy 22Ah SLAs mounted in the frame. Thanks.

[DAND214]

As always, Google what you want. but as always here is one. 24v piece of crap kit. Motor watts are not what they can do. A 24v 350 watt on 36v or 44v would be much faster. no gearing guessing, much easier and lighter. Biggest worry is that you cannot wire this thing or even mount it. NO 2X4s needed so what will you do? https://bmsbattery.com/ebike-kit/41...tml#/313-throttle-half_twist_grip/214-rpm-328
20mph maybe real speed not 50 mph miss geared thing but real speed demon :lol: :lol:
There is a lot more, all you need to do is search not drink!!

Will it make up a hill with me on it. I am on a bus with my tablet.

 

[DAND214]

Probably not if you don't pedal. First you want a 50mph death trap then a mountain goat. Do you have any idea what you really want/need? Here is one that will climb your hill. http://em3ev.com/store/index.php?route=product/product&path=50_36&product_id=138
Speed costs money, you can calculate all you want but if you don't get the numbers on both the paper and the project it won't work! Just because you have the numbers right you need to have the AMPERAGE/watts to push the numbers. Your SLAs are not ever gonna do it. Yeah you can parallel them all you want but the more you add the more your gonna need.

Do you have any idea why they have gone to higher voltage?
the higher the voltage the more efficient it gets.
By using 24v you will draw more current than if you use 36 or 48 and so on. Yes 24v will work but it takes more amps to do the same job 48v will.

I am still blow away that you are such a scaredy cat when it comes to 50v. Yes you can burn you fingers or your house. What I have learned is, not to drink, especially when I'm working with something dangerous. That being batteries, cutting down trees, working under a car, doing a roof and more. Any thing can be dangerous while drinking.
Maybe that what gives you the tough attitude you pose here. "I'm gonna punch him in the face". Haven't you learned that will get you no where but back in the slammer?

As asked before as why do we keep posting to this thread and I still ask myself. I guess it's because it's been something to do other than laughing at myself.

LC you really need to read and learn what is posted here. NOT JUST ON THIS THREAD but there is so much here on ES to learn about EV's. How to what to do or not to do in many different things.
Oh well, I guees this was a waste since you don't listen to DA, Sunder or me most of the time, just go back to the 2x4s or better yet try some 2x6s.

As the Hub Motor Turns and the Lipo Fire Burns. Wheels and deals.

I just got off the phone with Doug. He posted his number on Facebook message. The quad core computer I built that I never use and collects dust I am trading to get my blue Diamond Back back. I miss that bike. It is my favorite color. Also it has chrome handlebars and forks on it now.

Also Doug said the Kink bike is total shit. That is ok though as the rims are almost perfect. Especially the front and it came with a pedal chain. My plan is to order the 350W hub motor or 500W one if I can get one for about the same price or under $150. It has to be lightweight and silver or chrome as the Diamond Back has a lot of chrome on it now. That will be my new build for next month as these chain drive set ups on the front have proven to be unreliable to say the least.

Hopefully tomorrow or this week I will pick up the #415 chain and Doug says he can fix what is wrong with the red bike with extra parts he has there. His house is also closer to the bike shop where the #415 chain is. It makes sense as the red bike is a heavy duty frame but looks like shit as red is my least favorite color. Hopefully if all works out I will have both bikes up and running by my birthday on April the 26th. Thanks.

Take a break, go for a few rides on a working one...

You'll soon change your mind.

It looks like a pretty decent kit. A little heavy at 24lbs but when the weight is in the front and the bike is 20" it still goes up and down stairs easily. Perfect for the diamond back. I did the trade for it but he is keeping it there for me so I can make sure the brakes and pedal gear work good before I take it home. I would like to install the motor there also.

All I will need is the #415 chain for the red bike as Doug has the parts and can fix that too. I just have to try to get it there. That is the only problem. I still need to install the spoke sprocket and change a tire then tighten up the #25 chain as best I can and bring the wheel with the spoke sprocket there. The bike shop that sells the chain is close to Doug's house.

It is all on my to do list but I still on time out for awhile. I may try to install the spoke sprocket tomorrow though. I have had other business to attend to. SSA is trying to screw with the ol lady's check and they switched me from SSI to total disability SSD and want to place the money in a different account or something. Thanks.

Got my whole Tuesday ruined - Shooting - Standoff

 

[latecurtis]

Wow. Heard something about it on the news. Ol lady just said there was a big shooting. Didn't pay too much attention to details. Small world I guess. Crazy shit

Hopefully it wont come out in the media and the guy wont find out you helped out police. People do escape from prison these days you know. ( Richard Matt and David Sweat).They also get out some day but in this case probably not for at least 20 years. I might have done the same thing if I were in your shoes though. I don't like police but if I had family or friends in the building I would have helped the cops too. At least you got out of the shitutation with a whole skin. The poor guy that got hit though has got to be hurting. OUUUNCH!

Up early to make sure the ol lady answers the phone at 9 AM. SSA is calling and if she don't talk to them no more SSI for her.
That means I will have to pay all the bills next month and wont be able to order that hub kit for the Diamond Back.

The way things are going with the red bike I feel there is only about a 50 50 chance it will ever be reliable. I am only giving my chances that high as I have had both the Diamond Back and the red bike running many times with the front mount but only for brief periods of time. Also it ran much better with the #415 chain and spoke sprocket. If it were a total impossibility however it could not have happened at all.

I am inserting this. That 50 50 chance just got a lot better in my favor regarding the red bike. Doug said something about an adjustment or tightening something up and I kept the front wheel stationary with my feet and turned the handlebars and they moved a good 1/2". The sprockets are now lined up better. All I need to do is make it Doug's house across town and pick up my chain tomorrow. Tonight however I will need to switch the tire to the better rim and install the spoke sprocket on to the better rim.

Once I get the bike to Doug's with the bald tire I will go pick up my chain awhile Doug gets everything lined up perfect and tightened down good. Then when I get back with the #415 chain I will put the 9T motor sprocket I JB welded on and the wheel with the spoke sprocket and make the chain nice and tight and then test it out at full throttle.

Yesterday when I was at Freeman's Bridge sports. (local bike shop here) You can google it. I ordered the #415 chain there and should be in by tomorrow. The guy had an e bike there with a rear hub motor and a lithium battery pack on the rear rack. 26mph and 20 miles range. 1200W motor he thought. No throttle or switches though. He claims e bikes are only legal for pedal assist in NY state. If there is a throttle on it it is supposed to be registered.

However I know for a fact they cannot be registered as I was at motor vehicles about 18 months ago and they said under no circumstance could any BICYCLE. (scooters and mopeds are different) with a gas or electric motor be registered or driven legally on the road. "they are not road worthy" Those were her exact words.

I know DA is more up to date on the laws and they are changing so I would appreciate it if you could keep us up to date DA. The police don't usually bother with stuff like that here but would like to know in case I decide to move out of Schenectady or take an e bike to the hill towns 50 miles west of here where I am actually from as cops are board around those parts.

The Mohawk valley. (Canajoharie , Fort Plain and ST. Johnsville NY.) That is where I grew up along the Mohawk river. It is where my mother, Two brothers, sister and a few old friends live. I was planning on getting some 20.0 Lipo packs and back up packs to go up there this summer on e bike trips. Those cops there don't have much to do and will pull anyone over for whatever they can just for recreational purposes. Lots of Amish people with horses and carriages. Hilbilly cops! :lol:

I have talked to a lot of people and most believe that Federal law trumps State law. My brother Cory said that too. Other people I talked to claim City or County rules apply. I would like to know what is true or false and perhaps have a copy on me of any federal or state law which would help me keep my bike and not get tickets. Thanks and please let me know.

It's usually not a matter of which law trumps which. It's a matter of jurisdiction. If federal law says you can have a 750w bike, and state law says you can have 250w bikes, then if you have a 750w bike and you are riding on a federal highway, you're golden. If you get to state or local roads, you'd better get off and push.

As the Hub Motor Turns and the Lipo Fire Burns. Ongoing projects!!! :lol:


Not sure how they hook up but I have seen chrome chopper forks on a 20" bike and they look fantastic.
I also am not sure if it would be possible to mount the hub motor on the forks. It might have to be a rear hub motor.
The only thing I do know however is I really want awesome chrome chopper forks on the blue Diamond back.
Another thing I do know is I am glad DA is ok and survived his ordeal. This forum would suffer greatly without DA. His advice and knowledge is not replaceable. I am sure he will be busy with his store and going to see his friend in the hospital. I hope the guy heals up.

Today i am doing three things.

1.) installing the spoke sprocket and getting the wheel ready.

2.) testing out the red bike the way it is since i worked on it yesterday. Maybe a short video if it rides good.

3.) balance charging the new lipo packs until they reach full. That may be done before the test ride.

from page 123.

If you blow a fuse, it means you did something wrong. So don't replace fuse and repeat exact same mistake? (Good news is ... fuses prevented 2 possibly catastrophic failures ...)
6" long bolts are not necessary to hold 1.5" item. Sharpen them ... if designed for chasing down pedestrians?

the other thing I may do if I get all that done is a small front basket for the front of the red bike. I would like to have it for the new lipo packs and run them exclusively. Not only will it eliminate running wires to the back rack for SLAs but I can have a cargo basket back there instead.

I hooked the harness up wrong. reverse polarity has blown three fuses. The Lipos wont as there will only be one way to plug them in. If I do run SLA again I will need to wrap black tape around the negative wire harness and red tape around positive.
As far as the bolts sticking out they will be cut shorter and at lease two of them will be used to support the front basket. I have been looking for the right size. It needs to be small and factory looking. Just big enough to hold the Lipos and would like to hide most of the motor too if possible by attaching something to the bottom of it.

Advanced auto has the exact fuse I need and looks just like the four pack I ordered however at over $4 a pop i need to stop hooking shit up wrong. I picked one up yesterday.


Also i will need to call the bike shop to see if the chain is there. I have much to do today. I also think I may have tightened down the circle thing on the goose neck with vice grips last night. I am happy I solved the mystery as to why it was so difficult to line up the sprockets. It was NOT my bizarre or unorthodox mounting method but the bike itself.

I have a lot to do today and am happy to be alive. (especially after the amount of beer i drank last night) :lol:
Every day you wake up and don't get hit by a stray bullet is a good day. I need to finish my coffee and get going. Thanks.

I have not got much done today however the Lipo pack is back on the charger until it reaches full. I want to get them both ready. I will probably wait until tomorrow to try out the red bike. The #415 chain is in but they closed at 6 PM and it was after 5PM when I called so I can pick it up tomorrow.

Other good news today is the ol ladies getting her check next month but it may be a few days late. Also the landlady wanted me to call her and I thought it was over the noise of working on my bike and the downstairs people said something but it was she wants me to put a fence up in the back yard that was taken down when she cut down all the trees. I will look for my friend Mike to see if he wants to help and give her a fair price.

I am happy as now I can build the Diamond Back next month and maybe even order that chrome low rider. :lol:
I sent Doug the link on face book and he said it is not a heavy duty bike and wont work for a hub motor as it would look dumb. Also a spoke kit obviously would not work. However a friction drive will work. Please post guys and let me know what you think. It looks like multiple projects for next month. A friction drive would work but I would need to remove the chrome fenders as one fender may not look good. I wonder if they would work on the Diamond Back. It would look really good with the chopper forks on it. A real show bike. Thanks. Post when you can.

I really wish I had an exact link for the parts in the picture of the friction drive. Landlady just called me. She did mention noise and I talked to her and am in agreement with her that a shed in the back yard can happen this summer. The pack is up to 4.2V per cell and at 0A. I am waiting for it to beep full so I can go to Wall Mart and look for a basket for Lipo and get my exercise. I try to walk about three miles a day for my heart. If I get a shed I want to know how to make it secure so it dont get broken into. An alarm that goes off upstairs and a battery operated floodlight system on the top of the shed to stop anyone from breaking into it. I will be able to keep all my big 26" bikes in there if it is safe. Please let me know about that also. Thanks.

[latecurtis]

As the hub motor Turns and the Lipo Fire Burns. balanced and ready.

I don't really understand why the charger never beeped and read full on the main screen but over 90 minutes for each pack and the charging amps were 0 for about 1/2 hour and all the cells were at 4.20 steady with very little blinking.

About 1 hour off the charger they settled to 4.19 to 4.17 being the lowest for any of the cells (only a couple each pack)
I decided to hook each pack to the balancer in balance mode for about an hour.

The results are obvious. The packs are holding their voltage and after about 10 hours are almost perfectly balanced and ready to be combined into a single pack. Too bad I cut up the parallel cable. However I can fire up the soldering iron and make a parallel cable. I don't have any shrink tubing though and need to get some.

It was too late to get it last night as Advanced auto closes at 9 PM. I guess I will have to run the SLAs one more time if I want to test out the bike. It is also too late to pick up the #415 chain as they closed at 4PM and it is 4:18 PM.

The #415 chain and spoke kit is my back up plan if the chain and sprocket on their now don't work. I might order a 800W 36V motor for the Currie and use the 80T and #25 chain that is on the red bike now for the Currie and use the spoke sprocket on the red bike with the 9T motor sprocket I made. However I plan on running the red bike for awhile first if it works good. i guess today is a good day to try it out.

http://www.ebay.com/itm/800-W-36V-DC-electric-brush-motor-f-scooter-ebike-ebike-eATV-DIY-project-/161593361018?hash=item259fb7027a:g:SHYAAOSwQItT7tja

http://www.hobbyking.com/hobbyking/store/__16227__ZIPPY_Flightmax_8000mAh_5S1P_30C.html

That is my plan for the Currie. Those 5S packs are about the same price I paid for the new 6s packs. When I build the currie again I will probably get four of those for 36V in parallel series. Since the original Currie setup was a 48V 1,000W 3,000rpm motor running at 750W and 2250rpm@36V and ran perfect I may order a 90T sprocket instead of the 80t as the 800W motor is rated at 2800rpm@36V. The Currie ran almost flawlessly for about two years before I got stupid and stripped it for the 20" build last spring.

The thing is though I want that chrome low rider. That will happen first before anything else i think. I think i can make a 9 hole spoke mount work with huge washers. I should be able to adapt it. i may need to drill some holes but should work. I could put the 900W Monster scooter kit on the lowrider.

Basically the experimenting I do is practice developing my skills. I lack skills. Like anything else if you don't practice how can you get better? I am trying to figure out if i mounted the wheel sprocket right or is it the bent rim being the weak point. I thought it may have been my lack of skills but the adjustment on the goose neck lined up the sprockets. now the culprit is the bent rim. I want to see full throttle again.

I will see after installing the new 60T spoke sprocket how much better I can get it running. Doug will help with the chain Monday when I pick it up.


Either way i really wish I could find a way to mount the Lipo packs over the motor in something for the red Mongoose. Also I would like to hide the motor with something. It looks too obvious for police if they see the motor. I have black paint to cover the wood. I plan on doing that outside after the test ride. Any suggestions as to how to mount the Lipos and hide the motor will be greatly appreciated. Thanks.

Ampflow in the rear with the overgear.

page 71 calculator. best gearing for a 5700rpm motor is 50mph. A 60T wheel and JB weld special 9T #415 chain.
The 4.5 hp AmpFlow is what is needed and rpm = 4900. calculater = 60T spoke 9T motor = 43mph.

4.5 hp + 1+ hp from the front hub motor could achieve 40+ mph if geared to.
The Dimond Back will be the fast bike. Thanks for posting.

As the Hub Motor Turns and the Lipo Fire Burns. Front hub kit for D back.

yea. believe it or not I am listening to reason this time and NOT ordering the low rider. My friend Eric got me into Pirates Tides of Fortune. Been playing. Got the spoke sprocket on last night. I got to go pick up the chain today if I can get away from the screen long enough. :lol:

It is going on the Red bike with the tire and tube on the red bike now. Also the bolts sticking out on the front will be cut back with a hacksaw today and the second cash box will be bolted above the motor to hold the new Lipos. Speaking of holding I am going to test them to see how well they held their charge.

It has been a few days. I will throw them both back on the charger tonight for about 1/2 hour each then the balancer for 1/2 hour each then combine. Before anyone says anything, both packs were LIPO balanced to 4.2V which read steady with very little blinking 4.2V for over 1/2 hour and close to 2 hours on LIPO balance charge and still did not get a full reading on the charger?

The packs cant be too bad though as one pack dropped slightly. I want to combine the packs tonight and run them tomorrow if possible. I have some work to do. I am still ordering the front kit for the diamond back. It requires 100mm which is about 4" , Here is a picture.

http://www.ebay.com/itm/Electric-Bike-Conversion-Kit-Front-Hub-Motor-with-20-24-26-28-700C-Rim-/151610151588?var=&hash=item234cab52a4:m:mdJv1BcnXEhFJd-_eTGPfmA

I can spread them about 1/16" easily. Not sure how much more. Please let me know if the kit will work on those forks. If not I will need different forks, I am happy to get the DB back. I am not going to get longer forks to convert to a chopper. Doug has some sense and talked me out of that. He said it would make the front unstable, especially with a front motor. I am pretty sure you guys would agree so I guess I am not building a chopper either.

At this point I will be happy if I can build a reliable 20" bike. I will then have two 20" bikes running one for daily commute and the red one for cargo. That is my goal and since I am not getting the low rider or building a chopper or 50mph bike at this time plus Doug is going to help me to get GOOD brakes on these bikes. I hope you guys will start posting again. Please let me know if the forks on the diamond Back will work. Thanks.
