electric motorcycle project

Bad day at school? What does that have to do with leaving a note? A pat on the back, a hand shake and a thank you are more valuable than anything. You dont have any idea yet what hell it is to lose your wallet and have to cancel and replace everything in it. Some things are irreplacable. It took me two years to straighten everything out after losing my wallet and some lowlife went crazy with my ID and credit cards. I guess you thought that I meant he might give you a monetary reward? No. You might have made a friend. He might be someone who could change your life. At 16, while I was working in that little hotdog stand for $3.25 an hour (minimum wage) after school, I did a favor for one of my regular customers, not expecting anything in return. A week later I was night-managing his little gold mine fast food mexican restaurant, making 3 times what I was making to start and all the mexican food I wanted to eat. He did always complain that I ate too much of his profits/food. A few years later he opened several more of those little gold mines, and one of them was 1/2 mine. Maybe the guy who lost his wallet owns a scooter shop.

Its not just what you know, but it is also who you know.

BTW, You have never built an EV? You should! Maybe not a 96V 1,000A racing bike with $15,000 batteries yet. You should learn to ride before you sit on a rocket. My son has about 10 hours dirt practice on my XT350. Do you own one? You said,

If you do, tell me about it.

Are you saying I can or cant use a regen controller with my motor?

Sir Popeye,

Looks like you are overqualified to build an electric motorcycle. Hell, you have built two awesome Ebikes from the bare circut board up. Hub motors too! Has MIT contacted you yet? You should be building Ecars. Just call me Olive Oyl from now on.

Read the whole PackCycle thread, half way through the S-Go threads. Still trying to see the vids. Why are you wearing a helmet but your passenger isnt? You have the right to kill yourself, but not other people.

Thanks, I want to try one of those CC IQ controllers if it wont hurt the motor.

Housing update...

Moved the sprocket more towards the center for even radius force support, notched input shaft for keyway, 1/8" half moon keyway tack welded to input shaft so it cant move, notched 10 tooth sprocket for keyway, removed some material from unused input gear for more chain clearance, installed two new sealed bearings, installed new ring retainer clip, cut housing end down to size, reinstalled the two secondary gear shaft plugs, cleaned housing a little bit, greased 19 spline end and mounted housing onto the motor with three grade 5 bolts, flat and lock washers. Going to put two small spot welds on the shaft so the sprocket cant walk off of the keyway. They can be easily filed away if I need to disassemble the housing later for sprocket changes or maintenance.
Its finished...

Theres about 1/2" clearance between the sprocket teeth and the housing so I can run a slightly higher/larger tooth sprocket for more speed. It disassembles in 2 minutes.


Housing fits onto motor like a glove with its inner ridge, perfectly centering the armature.

Tomorrow (3am now, uh, later today) I will start the aluminum motor mounts for the swingarm. The motor has 4 housing mounting holes (the 4th hole is not used because it is under the secondary plug on the housing) and the housing has two sets of three mounting holes. So there are 8 clock positions that the housing can be mounted to the motor. This will come in handy while fabricating the motor mounts.

The fastest ebike on the planet...
HI SPEED WARPAGE? This is why I would never put a bicycle wheel on a motorcycle Popeye.

Dont feel too bad, a month ago my son forgot to put the hood pins back on his '00 Mustang (We had to use hood pins because 5 months ago he pulled out in front of a car who had the right away and got the front end of his Stang ripped off and totaled the car. No one was hurt. If he had been 4' farther out in the way or on a motorcyle, he would be dead. The insurance company paid off, we got the car back and we put a Black Widow II custom hood and bumper, euro headlights, cobra fenders, cobra grill, etc ), well driving down the road the speed limit went up to 55 MPH, as indicated by the sign up ahead, he speeded up and the hood came up and crushed the windshield. He slowed down because he couldn't see and pulled over and ran over the damn 55 MPH sign, destroying the new bumper. Luckily, we hadn't painted the car yet. The windshield has been replaced and the Cobra-R bumper is on the way. Now he wants to ride a motorcycle on the street. I said learn to ride in the dirt for a year AND dont crash your car for a year, then you can get a street bike. Its hard trying to keep you kids alive. It was your fault... Slow down!

Where did that come from? I was complimenting him. Hes an electrical Genius. I completely agree, especially with the latter part.

A little help here please, Link? I think I have offended her and perhaps you? I sincerely appologize to you both.

I saw one those videos on your PackCycle or S-Go threads. The vid is someone video taping a guy giving a girl a ride in circles in a cul-de-sac. The guy had on a helmet but the girl did not. I thought it was you and your sis or GF since it was in your thread.... Sorry, its a dad thing... nevermind

So far, so good. Mocked up the right side aluminum mount for the swingarm tonight


The case on this motor is 5/16" thick. Can I electrically mig weld on the outside of it without hurting the motor? I really dont want to have to take it apart to weld on the case. I have used a set of ICE motorcycle motor mounts that already have the same arc as the motor case. I suppose that welding on the case will cause some electromagnetic quantum forcefield that will fry the motor?

I filed for the patent Friday. My lawyers will be contacting you if you do ;)

Did you build that 30MPH (deathride) skateboard yet? You think that AC unit hurt? Ride a 30MPH skateboard and you will find out what real pain is. Tighten up the trucks up all way (if it has them). Please dont do it though til I finish with this CR, I need your help to finish it.

Only be a few things can cause it:
Sprockets are not aligned with each other
Sprocket is not spinning true or is worn
^Dial indicator, laser level, or even a straight edge can be used to check.
Chain tension is too loose, too tight, or chain is bad

What kind of batteries are these?

Maybe someday I can be your friend and attack anyone who messes with you. Oh wait, I already did that :)

I have already made 4 "L" brackets to attach the motor to the MC mounts. So everything is bolted. Even the rectangular base support will be bolted to the swingarm. That way I can remove everything for the upgrade and change the mounting configuration. I doubt that I will run this motor more than a few hours, if that long. Just want to try it on "The Hill" then scrap it for twin Eteks. :)

I was curious about welding on a motor though. No way would I will take this or any running electric motor apart. After I put it back together, I would have extra parts left over and it would never run again. I have an electric phobia, love cottage cheeselike knurled flesh and blood though :)

Motor upgrade? Forget the Etek-Rs and LifePOs... Heres my (our) next motor

Drop this in a Hayabusa rolling chassis with 600 AC volts, a 90+HP controller, and a 12" wide slick!!!
Someday soon you will be designing motors that are powered by hydrogen fuel cells at MIT :)

That means they were doing their job? Hopefully, they got really sticky too. Better traction equates to quicker excelleraton and handling (less wipeouts)... Oh wait, Im talking about drag racing slicks... EVers want no traction and no friction. Nevermind :)
It was a happy day when they invented hard plastic skateboard wheels and trucks so we didn't have to use old steel rollerskate shoe wheels and frames on our homemade plywood skateboards anymore. Im old!

Doesnt the derailleur also act like a guide to keep the chain inline with the sprocket, even when you aren't changing gears? Tape your pants leg our use a pants clip?

Oh, PowerSonic PS-12180, IIRCs are SLAs too. Batteries will be in phase 5.

You can have the motor, but the cool custom totally tricked out phat stupid dope (Old english... Bitchen) patent pending housing end will cost $6,000,000... cash, no receipt

Chains and other moving parts at high speeds have a tendency to "harmonically" vibrate at the right frequency (speed). Even perfectly aligned chains and sprockets in perfect condition can experience harmonic excitation at a certain point if they aren't perfectly balanced. The longer the chain the sooner it will happen and the more warpage of the chain will occur. A dampner may be necessary to stablize the chain and stop the vibration. And, wear those freaky pencil-legged skater pants so you will look aesthetically appealling (referencing your painted wire problem :) ) right before you wipe out.

By definition, would that make it a motorcycle with cyclical foot pegs?

I think it is time to let this thread die and disappear into the abyss called the archives. Stay tuned for eleCtRic 250: Phase two

Dont make me break out a can of Spinach :)

So, are you stalking me now?
I'm not Popeye. I'm Olive Oyl. Link is Popeye. I was going to give the Spinach to him. Since you wont go away, please keep up with the assigned gender roles at least :)
