Anyone can increase their intelligence, it's called Neuroplasticity. Whatever you challenge your brain to do, it will adapt to be more effective at doing it. Whether that is physical, like balancing on a bike, or mental, like arithmetic, or refuting arguments, or seeing the funny side of any situation.

Quantum physics is fascinating. I wish I had more time for it. I've already put machine learning on my agenda (semi-work related), as well as deeper understanding of electronics. There is so much to learn, and it's not even just time. There's head space. Often, after dealing with a heavy mental load, I can't focus on learning, even if I enjoy it.

I am still not out of my severance period yet, still don't have a job, so I have had a lot more time to work on my electric motorcycle and its supporting parts. I should post up some photos soon. The Traction battery is now complete, including all the mounts to hold the BMS in place, though I am still working on getting water proof cable entries for 00 AWG wire. I've started doing up the wiring diagrams and actually doing some hook ups to dummy inputs, etc. Hoping to get some real progress over Christmas.

Hope you're doing well, LC.

I took the city bus turkey shopping last night. cold and miserable rain. instead of waiting 1/2 hour or so to get the bus back i crossed the road and took the bus to Massillon as it goes to bus station there and turns around and returns to Canton where I live.

I had a discussion with the bus driver as he waits 12 minutes at Massillon . He said he was looking for a street legal e bike to ride on his days off work.

I told him the difference between direct drive and geared hub motors. he is looking for legal 20 mph and pedal assist so told him to look up e bikeling motors on google and geared 500 watt motor like the two I got.

I also gave him the endlesssphere info for further questions reguarding batteries ect. and told him about lithium ion vs lead acid. I did not mention LiPo.

He told me there is a bike trail which goes from Massillon which is only 5 or 6 miles from me all the way to Cleveland. :D . It looks like i will be ordering batteries this winter for the spring.

Good luck Sunder with your project and look forwards to the pictures.

Everybody here on this ES forum. Have a great Turkey day. Thanks.

yes i got assurance wireless phone with apps.

I went to Akron on Monday to Pete's electric bikes with my 31 day bus pass, They were closed on Monday but can go back as pass is good until Dec. 7. Was not planning to go to Pete's. Just was board and wanted to see Akron.

I need to call them to see if he has a new thumb throttle. In fact will do that now.

How is the weather there compared to NY?
No snow here just a little cool at night. It's getting into the 40's at night. I don't miss the cold and snow but I do miss Chicago!

I took a ride about a month ago, still able to ride fine just hurts a lot after 14 miles. I really don't know when I will bwe able to do the 50 mile ride I've done many times.

Keep in touch.

Merry Christmas, LC.

Sorry for hijacking your thread, but I thought I'd update you, and give you some more ideas to tinker. I am getting back in the eBike game. New work place doesn't allow motorcycle parking, but has a bike rack downstairs, so I am resurrecting and improving my old eBike.

Basically I just want an eBike that's almost as simple and reliable as a motorcycle. That is, I dont want to be cleaning and oiling a chain constantly charging lights, truing wheels, fiddling with connectors, checking cell balance, etc.

There's a lot that's maybe, but here are some of my planned ones:

1. Graphene Lipo. Wanted LTO for safety and long life, but after 3 weeks of everyone telling me they are out of stock, or simply not get back to me, I gave in. Graphene costs as much as LTO, has a 30-50% longer cycle life than standard LiPo (but still only about 5% of the length of LTO, but is close to LiPo density than LTO density. It's not the best of the best, but it's still a good compromise.

2. Going to use this as a combined BMS and cycle computer:

Image

3. A hard case and docking system for the battery with a precharge resistor. So rather than fiddle with plugs and it arcing all the time, I'll 3D print a docking bay foe the battery with a precharge resistor that contacts first.

4. A 48 to 5v step down to drive the lights and safety cameras.

5. I'm thinking electro luminescent lighting for side visibility too.

These are the easy electrical ones, and will make the system as plug and play as possible. I can check cell balance on the bike, I dont need to fiddle with arcing andersons or XT90s, etc, only one battery for the whole system, etc.

If it becomes my main form of transport, I want to:

A. Change to a mid-drive belt driven bike.

B. Get at least front suspension.

C. Get a disc brake system.

What are your thoughts?

warm lately. Went to computer store a few nights ago about 4 and a half miles shortly after dark to upgrade my laptop from 4 to 8 gig DDR3 for 20 bucks.

Was not a complete disaster as after I hit something in the road I could not see I got a flat tire and ended up pushing the bike for about a half a mile.

I talked a guy at the gas pump into giving me a ride to the computer store so was successful with the upgrade. I tried selling the bike for 200 bucks several times before I got a ride to the computer store and after but ended up taking a bus back home with the bike where i pushed it another half a mile home.

I learned three things from the experience.

1. Don't go anywhere at night because I can't see worth a shit.

2, Stay off the main roads as they are for cars not bikes of any kind. It is suicide. I am just asking to get run over.

3. Do not bother trying to sell a e bike because if it is not meth or heroin it will not sell.

Most everyone around here either drives a 50,000 vehicle and is straight edge and not interested in e bikes. Or they are a drug addict with nothing because all their money goes to support their habit.

I wish you luck with your projects. You are at a much higher level than I was even when I had the e bike workshop I miss so much.

I need a car or pick up truck. I got 500 saved so far. Maybe where you are it is safe to ride an e bike but traveling from here to Belden village or Akron is not safe for me. I did it several times but no more. Everyone is in a big hurry and a_ _ holes are driving around talking on their cell phones running lights and going 20 or 30 mph over the speed limit. It is like playing Russian Roulette.

I don't plan on fixing the tire any time soon. I just fixed it awhile back and had to go to a bike shop and get washers to get the wheel back on right. I probably won't be riding for a long time. I got diabetes type 2 now so am walking whenever I can to lose weight. I was 232 a couple months ago and am down to 220. I am not taking medicine for it and trying to reverse it.

I am not taking the risk of another bike accident as just started working out at the YMCA with light weights as my right shoulder I screwed up has healed. The ortho doc. recommended surgery and so now is like my right knee. If I hurt myself again in either area surgery will have to happen or I will lose the use of the limb.

Too many holes and broken section on roads and idiot drivers in a big hurry to take a chance. Also all my projects are still in storage 500 miles away.

I still hope that some day before I die I can have another e bike workshop and get that 1,800 watt brushless motor and hook it up to a 20" BMX bike with a custom built 60 volt pack and get up to 40 mph briefly on a safe stretch of road with no traffic. There are areas here in the city like side streets that very little traffic rolls on them and in broad daylight a bike should be able to get to 40 mph and stop in about 3 blocks or less.

I am talking about smooth recently paved roads where you can see about 1/4 mile ahead and are no intersections where a car can pull out. Yea I still want to go 40 mph but not willing to take any chances having an accident doing it. I have been hurt enough times. I am taking a long break from riding but never giving up totally.

I miss my 5 e bikes in storage and probably wont be riding again until I get all my stuff. Good luck Dan and Sunder and will keep following this post as long as I am alive.

This is kind of the point of my sharing: to give you ideas you can achieve. I am not posting up much here about my electric motorcycle, as I know it requires a lot more money and specialist tools and machining.

These I have posted up, mostly because I know you could replicate it at an affordable cost, though I did forget you no longer had access to your workshop.

I know in the past, you've had issues making your build reliable, and have made mistakes like reversing polarity. I've only just shared some ideas of mine to get even better reliability and low maintenance from our builds.

Thank you. I need a pick up truck first though and eventually a larger apartment. I might be getting my storage moved here for new years but need a pick up truck to move to a larger apartment where I can set up a e bike work shop. I also need a truck to take my wife to doctors and get her out of the house. She never goes out and e bikes are not the answer for that.

I doubt e bikes will ever be my main transportation as I walk and take buses and need a truck to move and haul stuff around. When all those things happen then I will continue my hobby of building e bikes.

Most or all of you wondered why I built in efficient chain drives and even dual motor franken bikes. The reason was I was having fun and enjoyed experimenting. I was not building them like you do for reliable transportation however Easy street as well as my current full suspension bike I have here reliable.

However reliable is not practical. The roads are too dangerous and riddled with pot holes and I have already sustained serious injury to my shoulder flipping the bike and black ice ect. Once I get my storage here though I will be ordering the 1,800 watt brushless motor as well as a sprocket which will bolt on to a freewheel. I am done with spoke mount sprockets as they warp the rim and not reliable or practical for a high speed build that could last awhile.

https://www.ebay.com/itm/48V-1800W-Elec ... SwoFVaW0GN

was only 1,000 watts.


This is the one I was looking for.

2800 - 3300 rpm for the black motor,

4500 for the silver one.

The black one will use a smaller sprocket. :P

will need the motor without the kit so can order 60V controller separate. 60V > 2,000 watts. My next build. :twisted: :twisted:

I learned about gearing and also how to install motors on about any bicycle. My advice when first joining ES was a bolt in replacement. Great advice for someone only interested in traveling from point A to point B.

I understand and appreciate the effort in DA and others attempting to save me time , money and trouble ,,,, but. I am not an average ES sphere member.

I never was such a person and never will be. I like to experiment and test the results. I find building e bikes enchanting and savor all adventures doing so. It is my thing. And I miss the experience.

Building e bikes is the most awesome and exciting thing I ever did in my life as was a motor head in the 80s but not mechanically inclined. successively installing an electric motor and reaping any success was and is is very therapeutic to me. It is something a lot of people on this post fail to understand.

Thanks

Yea. I really want to order that. F _ _ k a car. I also want a 58" smart TV from Wallmart for 298 bucks. :lol:

196 cells for 16S - 12P = 31.2 AH < $ 300. Not really that bad. Definitely 40 mph with that motor and a 60V controller that is > 2 kilowatts.

you forgot to post the best part. The price . Very impressive. Most e scooters or e bikes cost twice that much easily. I heard about something like that which is very popular in California.

The only thing I can say about it that I do not like is the fact that it leaves out the e bike workshop. :x

You see more than half my fun is building something custom. Converting a mountain bike or BMX to electric and then going like a bat out of hell on it and making a video. Especially when I am told it could not possibly work. :lol:

Would I recommend it to the average Joe who is interested in electric transportation. Absolutely.

Thanks for posting and welcome to this post.

PS.

I will probably use my 26" Haro V3 for the 48V - 1,800W @ 60V - 2,250W - with 43 mph gearing instead of a 20" BMX bike.
I don't have a picture of the bike because it is 500 miles away in a storage unit but will google image it. It is a sexy bike.


Yep. That is exactly what it looks like with the original Currie battery rear rack on it from the first pages of this post. I had a 48V - 1,000W unite motor bolted to the rack and ran it almost two years so I know I can bolt the 1,800 watt motor to the rack which is almost the exact color of the Haro. :D

There's hobbies and there's practical projects, and while the two overlap, it's important to see them differently. My electric motorcycle is a hobby. My electric bike is a practical commute. In the first, I am doing a lot of custom work, getting it exactly as I want it. Some things are probably not done the way others would have done it. E.g. I am using LTO despite its cost, weight and reduced range, because I wanted longevity, safety and ultra fast charging.

The electric bike on the other hand needed to be done fast and just "work", so I went down a very traditional path of off the shelf motors, controllers, and management systems and LiPo.

For a time, your projects seemed to need to serve a practical purpose. You complained of chains coming off, things blowing up and melting, having to walk back, being unable to ride in the dark or the crappy roads that you have there. So we focused on that.

Also, when people like experimenting, they want to do something new, or that at least serves an unusual purpose, not just experiment for the sake of it. When people say "It doesn't work", they don't necessarily mean "I couldn't get it working at all". Often it means "It didn't meet my requirements for reliability" or "It didn't deliver the speed I was hoping for". So when you get it working, you might have a different expectation.

But if you are enjoying learning for the sake of it, and enjoying the results, I don't see any harm in it, but you do seem to want to learn through mistakes, rather than advice. Either way, I hope you are having fun.

Chains coming off:
Typical with worn chains ...
BUT, your problem is using chains and sprocket types designed for stable-strong mounting ... and putting them on flimsy bike frames.
Look at your sprockets!
They have straight-square edges for maximum contact-minimal wear, designed for precise-straight contact.
Any deviance will cause the chain to climb onto the tooth and off the sprocket.
Compare to the typical bike sprockets!
Chainrings and sprockets (410, 415 etc) in the more typical bike applications have teeth with angled edges, this allows for some mis-alignment and teeth guide chain to center for proper "flow".

Of course, if you want reliability, a basic hub motor kit has always been a better choice, especially with your consistently gearing choices for unattainable speeds.
You complain about hills but then gear for more speed than your motors are even capable of attaining.
Bad. Usually you gear for speeds well beyond the watt output capability of the motor, on the level!
Worse. This causes poor inefficient "performance" over your entire trip.
Worst. Because the motor is dogging along at 50% rpm speed, efficiency might be 40% rather than 80% if geared optimally, for 50% range.
Worster! When you hit a hill, torque multiplication, actually torque division, causes speed, rpm drop and inefficiency increase.
Worsterest!!! Compared to optimal gearing, you might be using 400% the watt input for 400% the duration. Which factors to a 1 mile hill vs 16 miles of hills - using the same battery.
... Not even considering the damage to battery and motor etc.
A little learning is a dangerous thing;
Drink deep, or taste not the Pierian spring:
There, shallow draughts intoxicate the brain,
And drinking largely, sobers us again.

I enjoy enlightening ... and enlivening the spirit of the innovators.

If you are still stuck on that 40 mph, get a hub motor with a 72v controller. Put your 72v battery on and go! 40 mph with 66v nominal is also possible.
I really don't recommend it with any pot holes or rough road, it's very unstable and dangerous even on smooth roads here in Florida.

You complain about hills but then gear for more speed than your motors are even capable of attaining.
Bad. Usually you gear for speeds well beyond the watt output capability of the motor, on the level!
Worse. This causes poor inefficient "performance" over your entire trip.

I thought I fixed all of those issues ?????????

The Currie got a 750 watt gear reduction motor and proper gearing with a 16 tooth freewheel sprocket for a 480 rpm. motor.

The one 20" bike got two motors and controllers and average gearing is 21.5 mph and total power is 1033W @ 24V.

The other 20" bike has the 800W hub motor kit on the front.

Then there is Easy street which has the front e bikeling hub motor which is 500 watt and is pedal assist on hills.

Then there is the other 500W e bikling hub motor on the back of my dual suspension bike with disk brakes which has a flat tire.

I am not sure what bike project you are referring to but for moderate hills the e bikeling motor is ok with pedal assist.

The currie can take mid size/grade hills with pedal assist and the dual motor chain driven bike steeper hills with no pedal assist as don't have a pedal chain.

Right now all or any future builds are on hold as well as a vehicle as I bought a 58" smart 4k TV with HDR10. I have 550 left in the bank and the rent is paid with utilities included and Mary also has about 550 in her bank and I am not planning on ordering any e bike stuff until I get my storage unit moved here or I save enough money to move back to NY.

I also have no friends here in Ohio. I don't do Meth , crack , heroin or any other dangerous recreational drugs like people do here. I just drink a few beers and maybe smoke a joint at the end of the day. During the day I eat low fat , low sugar and watch my carbohydrate intake as well as walk or work out at the WMCA on a good day. On a lazy day I don't do much of anything besides play my pirate game and watch TV.

Not sure when the next build will happen but a 2,250W motor geared for 43 mph should actually achieve approx. 40mph on flat land with a 16S- 6P - 96 cell 18650 battery pack. It wont be able to go up steep hills as it is not meant or geared for hills.

I have a dual motor bike especially built for that and a 1,000W unite motor I am not using which will go on the back of the 20' bike with the 800W hub motor on the front for a total of 1,800W and 26 mph gearing or whatever the top speed is on the 800W hub motor solo @ 48V on flat ground. I mostly ran it at 36V so will need to run it with a speedo to know how to gear the 1,000W unite motor on the back. that is an unfinished project. I will also need a 13s - 6P pack for that build.

On top of all that there is the 1,000W 26" hub motor SUNDER sent. the wheel is bent but am sure I can get that fixed at electric bike Pete's in Akron Ohio. That will go on the front of a 26: Giant Roam and will order a 1,000 watt hub motor kit for the back. Another unfinished project.

Also when I do build the 43 mph bike with the 1,800W brushless motor on the back if I wanted to use it for going up steep hills without changing the 43 mph gearing I could do that by simply installing a 1,000W hub motor on the front. You see I have proven over several times that you can have a bike which is geared high for top speed and still climb hills simply by running two electric motors. One for each wheel. Three motors are also possible if I were to build a push trailer and hook it up in the back.

Did you all forget that I did in fact come up with an answer for inefficient chain drives ??? My answer to that was a second motor on the second wheel. Heat now is split between two motors and controllers and they share the load. All that I need to do now is build larger battery packs to run two motors so I don't overheat the battery packs. :mrgreen:

Thanks.

I build e bikes. There not always pretty or practical but sometimes they work, at least for awhile. Immortality is not a dream but the future of our evolution. We were given the tools to forge our own destiny. We were created in gods image and shall evolve to live forever.

two motors 1,800W @ 48V Each running a 16S - 98 cell pack pushing the motors to 4,500W total using currie ezip rear wheels with the freewheel on both sides and a electric scooter freewheel clutch on each wheel and the correct sprocket could propel the e bike to 50 mph. :twisted: :twisted: :twisted: :twisted: :twisted:

Great. How will your shoulder do taking a 50mph hit. Fella, it’s good to dream, but more fun not being a cripple.

I don’t know anyone that does heroin or crack, or meth. Find new connections. Staying around losers rubs off.

You deserve better!

Have you seen the wiring harness that ebikes.ca sells? Dual drives are cool! I tried a 2WD MAC. After a week id had enough but I’m gonna do two lower powered 36v, a rear geared hub and a 350w mid drive. For no good reason other than I can. Like what a dog licks his junk...because he can.
Thanks Justin_le we're here thanks to you. All the best to the mods for their tireless work keeping it on an even keel.

Before throwing money into a 50mph bike ...

... just take any of your present bikes, with speedometer, up a long steep hill and let it loose.
Stop dreaming about 50mph on a bike and actually experience it!
Good chance you will never want to see it again?

Keep in mind that at 50mph hitting a pothole, or possibly even a stone, could crush your front wheel giving you a nice lengthy tumble with heavy motors and chains and gears.
A little learning is a dangerous thing;
Drink deep, or taste not the Pierian spring:
There, shallow draughts intoxicate the brain,
And drinking largely, sobers us again.

I enjoy enlightening ... and enlivening the spirit of the innovators.

First of all I do not hang around with losers I just hermit/ LoL : Like grizzely Adams. I don't hang out with anyone. Talked to a couple people and exactly what suspected was true. I don't like new faces. Never did. I am like my brother Jeremy who lives out in the bushes where the Amish do and don't like anyone. Antisocial. We don't ever hang out due to his miss. goody two shoes wife. Since I smoke weed I am the bad influence and already declared the black sheep in my frocked up family. I am separate from anyone I am related to and could really give a flying f + + k about anything. I drink beer and smoke a little weed. I am the black sheep of the family because I refuse to change. i want to be buried face down so the world can kiss my ass.

yea I know.

Had my share of accidents in the past.

All those mishaps were due to driving after dark plus broken sections of road , or Black ice and the latest a drainage hole approx 1 foot in diameter with grass growing around it.

I hurt myself many times.

One of the reasons I don't ride anymore.

Not one time though was it my fault due to building an unsafe e bike.

i rest my case.

LC. out,

PS.

If I ever do build an e bike which can do 40 or 50 mph I will be smart enough to accomplish it and record a video and still have a whole skin when posting the results. Thanks.

Stats are such a funny thing. I recall my economics teacher had a sign on his wall that said "An economist is a person who will put his feet in the freezer and his head in the oven, and say the temperature is lukewarm". I don't know anyone who does anything harder than weed either, but I live in an upper middle class area. The official stat in Australia is that 1 in 3 women will experience domestic violence in her lifetime. But knowing more than 3 women... Way more than 3 women, I don't know a single woman who has experienced that. I looked up the stats in my police precinct. It's actually 3 in 1000 for my area and I definitely don't know 300+ women, let alone 300+ women well enough to talk to me about it, to make it statistically likely.

I guess the same goes with drugs. Some areas of New York, you're going to be tripping over ahem... tripping druggies. Others, you might have a coworker microdosing on LSD or taking half a dose of speed to keep up the long hours, but you'd never know, because they're high functioning.

Been doing so much on my electric pushbike lately. I've got everything working loose, and went for a test ride a couple days ago - 1h 09m to work, including 4 wrong turns and slipping a chain. So when all's done well, I should be able to do it under 1h.

So some of the things I've been working on - Heatsink retainer for Phaserunner, so I can run it at max amps for longer:

Currently on the printer is this battery case. I wanted it stealth as possible, so this case is basically 1-2mm bigger than the raw cells. Since the drawings don't provide scale, it's about the size of 3 DVD cases stacked on top of each other. It gets me about 30ish km.

The top compartment, again, is only a few mm bigger than needed. It houses a BMS, step up converter (So I can charge it with anything from 5v to the full battery voltage - that means in a pinch, a phone charger can top it up!) and a step down converter - so I can run the bike's lights from the main traction battery.

Nothing innovative, nothing experimental, like I said, everything off the shelf... But I am determined to do this well. Reliable, professional, quality.

You posted that a few pages back. I wanted it more current so I don't lose track and have to search for an hour looking for it.

Are those the cells you are using for that or something else ? Since e bikes are legal in Ohio and Pennsylvania I could ride from here to Scranton PA. Then catch a bus to Albany but only would work in good weather with no snow or rain.

I really need a motor vehicle but am definitely not ordering anything else but these cells if or when I do another project. I like the quick charge as I can stop at any public library or any place that people plug their phone chargers in. It makes no sense sitting some where for hours charging if it can be accomplished in only a few minutes. It will be worth every penny.

Are there any other batteries of this type and are you using those or something better ? Is there any other new type of battery that is better ? Please let me know when you can. I am in no big rush to build anything any time soon as my storage , tools and bikes are still 500 miles away in a 10 by 10 storage and I have no idea when I can get my stuff. Thanks.

I ordered (and just received Monday) the 4Ah version of those, and I am going to put them in put them in parallel for an 8Ah battery.

I need about 5-6Ah @ 48v to get to work, so building itike that gave me a bit of flexibility as to how I can configure them.

I'm currently using 8Ah of 12S Turnigy Graphene. They are good batteries now, but I bet you in a year's time, they will be sagging a lot and have lost capacity.

My ride to work is really nice. There's a "slow" section through parks where I keep it to mid 30km/h, and some freeway with dedicated bike lanes, where I hit 65km/h due to a hill (motor can't go that fast).

It only takes me 10 mins longer than bus or motorcycle, and it gives me the opportunity to unwind, destress before I get to work/home. Really enjoying electric biking again.
