500w @ 36V (~20mph) geared hub motor kit available from USA <$200 but 26" ...
You would need to lace into 20" rim if that's what you want.
20mph/26" = 15.38mph/20"
15.38mph /36V = 18.975mph/44.4V = 20.5mph/48V
.. 500w @ 36V ..... 615w @ 44.4V ... 666w @ 48V
 
I wonder if you could start with one of these:

It would be a solid base to start from. From the size of it, I'd be willing to bet that the motor can handle way more than 1.5kw, and with a 45Ah battery, you'd get some decent range out of it. Modify the controller to put more current through, and rewind the motor if you need to for a higher top speed, and you could possibly have a 60km/h road legal eBike.

Since you're a bit... wildly optimistic, you could just put your own motor in there, get your own controller, replace the ECU with a cycle analyst, and upgrade the battery, and you could probably have it engineered to be still road legal.

Either way, it'd be way safer than starting with a bike frame.
 
Poor cargo capacity!
Could barely fit 2 12 packs on it!

Meh, Nothing a backpack on your back, one by your feet, and two panniers wouldn't fix.
 
Wood brackets did not work out well. Had to go back to the heavy steel. Will test it tommorow. The red bike is a Mongoose. Defintally going to get a light hub motor for the Dimond Back now but waiting until next month when I get more money as I dont want to take anything out of the bank.

The pot is a miracle as I ride the sidewalk a lot because the cars here are reckless. Driving 20 or 30mph over the city speed limit is normal here and I prefer to stay out of their way. the pot. and kill switch makes the bike safer and easier to maintain 3 to 5mph speeds. Whenever I talk about going really fast like 35 or 40+ mph I am not refering to anywhere here in the City. Only 25mph is safe here and only in a few areas as of poor road conditions.

Actually a really fast e bike capable of 60mph could only be done safley on a flat country road in daylight summer roads. Somewhere you can see a mile in each direction. Amish horses and carriages ride around there. there are very few cars. My brother and brother in law race four wheelers there. Also a helmet,which I have and any other sort of saftey gear they wear I could too. I want to blow them off the road but my brother in law has one that goes 80mph he said. It would take a lot to beat that.

I need that light hub motor for the DB. What is the difference between a geared and non geared motor? Will a 24V controller handle two 4s packs or 4.2 * 8 = 33.6V? I want to use those $20 packs. Please let me know. Thanks.

OMG that is what I talked about a few pages back. I found it researching. I got feedback from Skalabala.
My motor is suppose to be the same as the BHT 1000W one that could handle up to 7kw.
I am going to build a 4spd gearbox for it so it will work nicely :mrgreen:

I posted yesterday.
It will have dual 3300W 4.5hp AmpFlow or the back with heavy duty spoke sprockets on either side of the rear wheel and the 5 killowatt Crown hub motor on the front.

He lives in South Africa so I posted.
we can get speedometers and a stop watch and put someone on the start and finish line and race that way and post it on youtube. Hell with the video technology we have today Both videos could probably be combined so it would look like we were actually racing.

his reply.
Sound fun :D
I think ES must actually have a thread dedicated to acceleration and top speed videos and with your specs stated 8)

i looked for it but did not find. I want to know how to beat that 80mph gas powered 4 wheeler. Please help me with my quest. If even one of those assholes buys an electric car afterwards it could help save our planet.

Heard from LVP. Still looking for an FX motor. I am a motorhead. The only thing different is I am an electric motorhead now. Thanks

Hub = large-heavy 350rpm motor
Geared hub = small-light 3500rpm motor + gears (freewheel option common - no "drag" from pedal alone)

LVC and HVL varies, dependent on controller.
24V brush controller I recommended was tested from 20V through 50V+.
 
PTP (Points To Ponder)

Speed
Gearing for 30mph+ ...
then running at 20mph - ...
severely degrades performance!

Greater than 20mph is liable to get you noticed ...
30mph+ is certain to get you noticed >> pulled over >> ticketed! >> jailed if typical attitude exhibited!

Brakes
Important!
For your and everyone elses well being.
A bike with good brakes, properly tuned, can stop from 20mph in about 20 feet.
Rear brakes only are rated at 33% effective.
That relates to my 20 foot stopping distance + about 4 lanes of traffic.
Imagine the stress caused to all the people trying to avoid you as you gradually decelerate crossing a 4 lane highway in front of them.
Worse! ... consider the life trauma you cause the poor girl you glide in front of ...
the blood smears and crushed and torn body parts protruding from under her car ... possibly quivering or twitching still?
Could cause her nightmares and necessitating prolonged counseling treatment.

20incher
Small wheels are a horrible choice for rough sidewalks or pothole strewn streets!
Short wheelbase makes heavy braking fairly hazardous, combined with high center of gravity, becoming unreasonably hazardous.
Adding a 5kw motor and ~300lb to a bike designed for a 90lb 12 year old is a train wreck waiting to happen!
You know what is going to happen ... you know it is going to be ugly, you shout warnings even though you know they can't-won't hear you ... worst of all, you seem hypnotized and just can't look away!

Front Wheel Drive
Extreme care must be used on less than perfect road conditions.
High power front drive - poor throttle regulation can put you down in any situation!
You can easily recover from most rear end "fishtails" but a front slip is nearly impossible to recover and "put down" is nearly instantaneous!

Battery size
High C rate discharges quickly destroy batteries
Saving weight with small batteries means the need for new batteries 4x(?) as often.
Saving money with smaller batteries will likely cost you twice as much! ... in the long run.

Battery Deep Discharges
Discharging battery after "it slows down" and "was able to turn back on after a couple minutes and go a little further" etc. indicates severely deep discharges ... sucking the minuscule remnants of energy from the battery and causing severe damage-degradation.
Controller LVC (Low Voltage Cutoff) is the last ditch effort to prevent catastrophic damage not your nearing empty mark.
For reasonable battery life ... you should discontinue discharge before motor starts slowing down!

Three questions.

1. Does it need to be fully electric?
2. Does it need to be repeatable?
3. Do you need to survive the experience?

If the answer to all of those is "no", then I've done the maths for you.

344 of these attached to your bike, will accelerate 300 pounds at greater than 1g: http://www.hobbylinc.com/aerotech-g40-10w-white-lightning-motor-g-composite-model-rocket-engine-74010. Those rockets burn for 8 seconds.

At 1g, after 1 second, you will be travelling 9.8m/s. At the end of the burn, you will be travelling at 78.4m/s. This translates to 282km/h, or 176.4 mph.

Wile E. Coyote. Super Genius.

Not sure why I would do that unless I was extreamlly drunk. Kind of seems like I would be accelerating instead of decelerating crossing a 4 lane highway to make it across. Anyway I Will be testing the bike tommorow if it dont rain. It rained all day today. I am still sticking to my story that the skill of the e bike rider trumps anything to do with brakes. It goes the same with any motor vehicle gas or electric. The skill of the driver can overcome almost all shortcommings. Watch the fast and furious. I just watched Furious7 for the second time.


Yea I did that to the 12Ah SLAs. Why would I care I got four 10Ah SLAs and two more comming and the four now never ran over 3 miles and only exceeded 15mph for a few seconds. I will soon have 36V@20Ah any day now and will be posting a video soon. I will get a speedo and at least 25mph soon out of the build. My next build will be brushless and at least 40mph. thanks.

Thanks.

I hope you realize the fast and furious is a movie. It is make believe,not real. Good luck in your alternate reality. :lol:
 
Brakes? What is that? Don't use mine on downhill trials :p
 
Got to take the movie back to red box and pick up my last two SLAs at the USPS office. I got a note in my mailbox. Hopefully the sprockets line up and the chain stays on.
Too dark outside to do a video now. Hopefully tommorow or later this week. The sidewalks are as bad if not worse than the streets here. Very piss poor conditions. Schenectady spends all their money rebuilding downtown and are putting in a big Casino and dont give a rats ass about the rest of the city. It is ridecelous.

Like I said before I wont be breaking any land speed records around here. I am just hoping to not pop a tire and keep the bike upright. Also there is broken glass a lot on the roads and sidewalks in a lot of areas. People also litter a lot around here. Garbage everywhere. It is disgusting. Not only do you have to worry about running over glass but there is always a chance of being hit by a stray bullet. Gang bangers are shooting each other every week here and they call this area Mont Pleasent. Imagine that.

Also I have to ride thru the hood just to get home from downtown and 20mph or a little more can get me out of problem areas quickly as long as I dont hit a huge pothole. During the day I can see but at night potholes are a huge issue. I will be getting a bright LED headlight and a reflector on the back for saftey. My brakes are fully operational. They are not as good as Cantilever or disk but they will stop the bike now.

I can do a video in the parking lot. I would guess about 25 to 30 feet at 20mph but am not sure. They should be as good as they were in that video I posted awhile back where I got up to 23mph or so and stopped for the stop sighn. It was awhile before the controller fire video a while back. Got to go now and pick up the SLAs before they close. Post when you can. Also Skalabala, Keep us posted on how that motor project of yours is going. I would like to see that in action. Thanks.

As the Hub Motor Turns and the Lipo Fire Burns. Sidewalk Special reloaded. / which bike for 50mph?


Sure I already posted the sidewalk special before. This is a different bike so it is reloaded.

The chain is good. About four miles and still nice and tight. The batteries were in and I put them in the back. Five SLAs and the weight is totally ridecelous and adding one more for six SLAs for 36V@20Ah is insane! For speeds under 15mph and distance of four miles or less I dont see it neccessary to haul around all those batteries. I went to the drug store and found that basket and placed it on top of the batteries as seen in pic3 so people would not notice the batteries.

Anyone with a scooter or power chair could steal my batteries in a minute. At Wall-Mart I decided to get 100 zip ties for about $3. The reason is after I hook up my batteries for a trip I can zip tie that on the back over the SLAs and haul up to 20lbs back there if I only run three SLAs instead of six. I dont want to put much weight in the front basket as the motor and those brackets are enough weight. This system is superb as with a large back-pack I am good for at least 60lbs. 20 in the back,20 in the front and 20 in the back-pack.

I will eventually need to get more zip ties as when I get home I have to cut the ties to take the batteries upstairs to my charging area. That is acceptable though as they should last about I month anyway. As far as the overall saftey rating of the bike it goes according to speed and road conditions. On small hills not very steep it rolls down them surprisingly slow. On the flat the bike decelerates quickly when cutting motor power. From 5 to 10mph the bike is very safe. 15mph the bike is moderatly safe as long as the roads are smooth. The fastest I will probably go with it is about 20mph if I decide to run all six SLAs.

As far as the bike putting me down fast as DA. said; a couple of weeks back when I ran that variable controller that made the terrible noise and cut out at low speed I finally opened up the throttle for a few seconds and about 18 to 20mph I would say I hit two pot holes with a man hole cover in between but did not lose control of the bike. Five 24oz cans of beer came up out of the front basket and one of them broke suds all over the road. It scared the hell out of me and I gained a new respect for the bike. I dont go fast now. that also was with the Dimond Back and it was a miracle the shock I butchered did not snap and cause a serious injury. I got lucky.

Both brake levers on each side did not work well (pic2) so I decided to lose the throttle and run the pot. exclusivelly and I moved the front brake handle over to the right handelbar where it belongs. The cable needs to be shortened and hopefully it will work better. The brakes could be a lot better but at slow speeds under 15mph it will work for now. At least it is functional. I wish they had good deals on 5s packs like they do 4s packs. four 5s packs would be much better than hauling all those SLAs around. I wont be ordering any more any time soon.

I am going to hunt hard for that geared motor for the DB. I need a lighter bike! 24V is fine and four 4s Lipo packs in parallel series just makes sense to keep the weight down this time. I would like to get it next month as well as studded snow tires for it. I do agree with DA about it putting me down fast on slippery roads though. I wont even ride the red bike if it snows or is snowing out. Not worth it. With an overall saftey factor of about 6 on a scale of one to 10 at 15mph and 8 or 9 at 10mph or less. It drops to below 0 as soon as the roads are covered. That is why I need a rear hub motor for the DB. and studs in my tires for when it snows as the only way the red bike would be 100% safe when it snows out is to keep it in my closet on time out.

http://gocarlite.com/400-watt-geared-motor-kit/ Just found this on google after not seeing anything on e bay. Have to call the dude. Another Doug! OMG!
Looks like the Dimond Back will be going about 27mph with the LIPO packs. That will be my light and fast bike and the red bike can be my slow powerful bike as it is decent up hills I noticed. I also pedal assist a little now. Can hardly wait to get that motor. It dont look very heavy in the picture. Had a cheap one on e bay but no freewheel or gears. It was for the front though and I'm looking for rear. I'll find out tommorow the price and more details when I call.

Also now that I have extra money the Currie needs a motor. I wonder if I could put two motors on the Currie. A hub motor on the front and a chain motor on the back for say 40mph :twisted: The master plan is.

Red bike <20mph. medium hauling dual baskets up to 50lbs low range <5 miles <10mph

Dimond Back >25mph <30mph. light hauling up to 30lbs one basket medium range about 10 miles <15mph

Currie 40 to 50mph dual motors. heavy hauling 60 to 70lbs one huge basket. long range 15 to 20 miles. <20mph

Schwinn 25 to 30mph no hauling super range up to 50 miles. <20mph


Thanks. Just told the ol lady about 4 total e bikes and no car. How do you think that went over? :)

LC. out.
 
Why do you have four ebikes LC? One is more than enough!? :shock:
 
May even have five e bikes. Dont forget about this guy. See roadmaster. Ordering another 36V controller so I can run dual 24V 280W Unite motors on the back at 36V in series for 2100rpm and 420W total and 17mph with the 80 tooth #25 sprocket according to sprocket calculater on page 71 with a 20" wheel.

may replace the unite motors with dual 3300W AmpFlow and add a 3 to 5 killowatt hub motor on the front for fun later on. :twisted:

youtube was taking 16 hours to upload with my connection speed. Was easier to take out some video and split in four parts. part 4 showing about 25 feet to slow from 20mph going downhill to about 3mph to the sidewalk.

Drove about 3 miles on three of the new SLAs that needed to be broke in and about 4 miles with the other 3 that were broke in. About 7 miles total today but under 15mph on flat and pedal assist up hills. The brakes could be better but they are operational.

Should be good as I went down a much longer hill after the video and was able to control speed all the way down. This build is offically finished and my 20" Mongoose is an official custom e bike build. Thanks.

LC. out.

PS. Just got back from a short trip <2 miles with the shitty old abused 12Ah SLAs and they made it about 5 to 7 mph. Will still get my moneys worth on short trips. It will save the six new ones I have. :mrgreen:

They might have to sit for a bit though as I got three of the new ones on the Mega charger and the other three on the 3 stage charger. I could break out the Sky charger but dont have a second set of charging cables. I should get a beep and a full reading or a green light on the 3 stage very soon now though. :D

The old SLAs still have life. I just checked the voltage and got a 12.95, 12.96 and 13.0V. I think if I recharge them and desulfate them then top off the charge I can get a few more short runs with light pedal assist <2 miles. 8)
