First Build: cheapy frame + GM arcane pastries of some sort

[stinkler]

This is all your fault endless sphere!
I was just minding my own business browsing Hobbyking for quadcopter parts and I stumble on to these enormous 80-100 motors.
Well I knew somebody had to be doing cool stuff with them.
So I searched around for crazy people doing crazy things with electric motors. Guess where i ended up?
Hours of reading and watching videos led me to this fact: I need an Ebike Right now!
Pretty basic setup so far. Got the deathtrap genesis frame, 48v yescomusa ebay kit, and 4 6s1p 8ah lipos for 12s2p from our dear friends at hobbyking.

See wallet I can be practical. 48v is plenty right? *TWITCH* yes of course...must..not...stray into 60mph zone. That way madness lies.

So What am I missing?

[wesnewell]

I don't see a drip loop in the wiring to the motor. Wire should be facing downward to keep condensation from running into the motor. You've got to change the tires and tubes. And use friction tape or heavy rim tape on the rim. I like the CST Cyclops 2.4 tires and XLC 2.3-2.75 tubes. And 5" riser handlebars if you don't have long arms so you can sit more upright when riding. Looks good though.

[dogman]

Yep, street tires would be next, followed by one of Lyens excellent 12fet 72v controllers. Only a few packs more for 18s

Whatever you do, don't click on anthing that says cromotor, just yet.

Oh, and body armor.

[stinkler]

Nooooooooooo! The lipo gods are punishing me for my hubris!
Got my packs today and one has a cell at 2.3v and 1.4v.
Do I attempt an rma with hk?
Or do I cut it up into a 4cell and move on.
Ahhh well I still love you hobbyking.
Even buying it twice is cheaper than domestic lipos.

Good first build, I now have too many ebikes to be playing with the magic pie. It looks to be a good hub motor to run higher voltages on. Good balance between weight and torque.

You could move the controller to the bottom of the tube and use the triangle space for your batteriies.

[neptronix]

( btw, that's not the magic pie, it's Golden Motors' lower powered, smaller diameter cousin. )

[stinkler]

Aww its not a magic pie? Is it even a little magic?
Does my hub motor have an equally embarasing name?
I will have to edit my title to better reflect the essence of my build.

So much good advice, thanks guys.

Oh and the only low cells I have are brain cells!
Turns out I read total pack voltage as 2.20 instead of 22.0 and thought it was cell 6......derp

[kfong]

Haha, I didn't even notice it wasn't a magic pie. Should of caught that. Hopefully you have the 1000w motor. that version has some magic to it

[LI-ghtcycle]

Don't worry, everyone's first E-Bike motor still has some magic to it, however, that magic tends to wear off once a year until you build a bigger, faster, leaner E-Bike, then the magic comes back!

The controller I got with this 1000watt kit came with a pedal assist sensor. Do I have to use it?
Oh and the brake switches, do they just cut power to motor?
I can't get this thing to spin and those are the only 2 things I don't have plugged in.
Why did I leave them at home *facepalm*
Its the yescom 48v 12fet non infineon one.
Anyone have this thing?
*edit* it seems that the function of the brake switches is to release the mystic smoke that powers the controller

whats a good controller for a 48v 1000w hub motor

[stinkler]

The thumb On/Off switch wires have become one big melty looking wire.
I will repair them. check all my connections and start from square one.

Its always sad when electronics go boom but man i love that smell haha.
smoke is just weakness leaving the circuit board
welp back to the shop.

Will my pedaling never end?!
am I doomed to a life of healthy exercise?

Nope to PAS and yes to your question about the brake switch.

Although smoke is somewhat bad, crack open the controller to see what you cooked. Take pics and upload, maybe you can repair it.

And if you did cook it this hua tong controller will work nicely

And for similar builds check out ZOMGVTEK's, migueralliart's, and mine

[wesnewell]

You don't need the PAS sensor hooked up normally. But, if you got a European kit, you may need to make or break a connection for the controller to work without it. The brake switches, cut the motor and activate regen braking if you have that enabled. Don't worry about the motor not being a magic pie, it's a strong 1000W motor that I've put close to 4000W into without a problem. Assuming you got a thumb throttle with the red kill switch on it, the switch has to be out before the controller will function and motor run. I got a 15fet EB215 Infinion controller with mine and haven't seen the newer ones. If you don't have all the throttle wires hooked up then the controller also won't work because the kill switch is one of those connections. Should be 3 plugs from the throttle. One is the throttle. One is for the leds, and the other for the kill switch.

Ouch. Welcome to Ebiking, and learning why we harp so much on who to buy from. With a great deal of ebay vendors, it's just a ship you a box that they got from china deal. Often nobody is opening the box and testing stuff before it's sent to you, so it's a bit of a pay your money and take your chances deal. Worse of course, if the untested stuff is shipped from china. CS gets more complicated if the sellers english is poor. One reason Cellman is good is he speaks english. Really good vendors test everything in the shipment container before shipping it out to a customer.

My first ebike kits, I was two for two on something going poof immediately. One controller my fault, let the motor axle spin and cut the wires. The other was a charger that went poof. First of a series of chargers that didn't last.

Hopefully, you will get sent replacement stuff on warranty quick.

Lyens is my favorite controller source, and he also sells a very handy thing, a tester for checking motors, controllers and throttles.

[wesnewell]

Try and get yescom to replace your controller under warranty. If not, I've got a 12 fet 30A basic controller you can have for the price of postage.

[stinkler]

Wooo! Got it going! So damn cool.
Pulling 18 to 20 amps at 28mph.
I am impressed with the torque and smooth accel.
Haha total ev grin over here.
Spare parts offers and good advice, what a bunch of cool guys : )

Just one crap cell in the bunch won't go over 3.8v.

Here is the "I don't care what it looks like just make it go right now"


Then after I got that out of my system it was taken apart and cleaned up.


Made a battery holder out of some aluminum flat stock and a top to a project box.
Its pretty much a bottle holder's tarded cousin.

Seems sturdy but I don't trust those 2 nut inserts.
I'm getting a new hardtail so this wll do for now.

[stinkler]

made torque arms out of some flat steel.

should do for now.


After jammin around all day im really close to ditching this frame for a steel hardtail.
this thing is just too damn flexy and the suspension was made for 5 ft 160lb person.
what seemed fine while pedaling is terrible at 30mph.

Passed a 3 person spandex roadbike convoy today haha is that not the most satisfying thing ever!
I couldn't stop giggling

[biohazardman]

Be sure to check your tire pressure, suspension points for any play and spoke tension before you blame the frame. My hardtail was way slack, frame wise, when compared to my suspension bike. Good you could find the ES and get the addiction like the rest of us. Nice job and good thought on the torque arm.
I don't see your location on your profile. Is a good thing to have it there so we can have a better idea of where to send you for help and or to purchase products.

My first ebike commute hooray!
batteries held up, bike handles traffic well.
used about 4 amp hours total
I think I'm good with 8ah pack for now. (till I get the more amps sickness)
the motor doesn't even get warm and I'm so far below my lipo's C rating.
So tempted to solder the shunt..maybe just a little tiny bit...a teensie tiny....damn I didn't even last one day.


Im interested to see how some nice road tires will change the amp draw at cruise.
I like the look of the kenda 838 tires are they any good?
I am torn between the kenda and the CST Cyclops that wesnewel recommended.

One thing that had never occurred to me when selecting tires, is the ability to put the bike on the bus.

If you think you might ever need to take the bus part way for a commute, or just want the option as an easier way to get home, the Cyclops at 2.7 inch wide isn't going to fit the bus bike rack, or most bike racks that you might lock up your bike to.

Otherwise, I would say go for the Cyclops, I really like mine, and I am a huge fan of balloon tires and rigid frames VS suspension, each ot their own,

[shock]

Nice looking build! Question, does that 48v 1000w rear ebay kit come with a ISO disk brake mount?

it comes with this threaded thingy.

I want a hardtail so bad but I think that they do not exist anymore.
The local bike shop had ONE 800$ hardtail out of maybe 30 bikes.
ARRGH! don't want linkage all around my center post, that's where the lipos live!

If anyone can point me to a large or x-large steel frame I would be thankful.
being a 6'4 230lb ogre and riding a 130$ aluminum wallmart bike at 30mph is terrifying.
When I pedal the whole thing flexes and it wants to walk all over the place.

but other than fearing for my life its very smooth.

[Beachcruzer]

Lots of hard tails on Craigslist for way less than $800. Get a quality old school ride and pimp it with the electrics you have now. It'll be badass.

[wesnewell]

Walmart sells lots of hardtail steel frame bikes, from the $59 one I bought, on up in price.

That's true, but then you will have a WalMart bike. You can get a pretty high quality bike on Craiglist or similar for very little money, especially if it's an older style like a hardtail mountain bike or steel road bike. That gets you better components from soup to nuts, including things that really matter when you're going 30mph, like brakes and wheel builds.
