On my build thread. I pull the side covers off using wooden shims. Unscrew all the screws off the wire side cover. If some screws won't come out because of how tight they were put in leave them for last. For the screws that don't come out with the screw driver: I put the screw driver on the screw an...

How did he break the axle? :shock: the quality on these motors is real questionable isn't it man? I don't think he would have blown the controller, unless your son gunned the throttle after the axle broke. If you know someone with a 2-ton press use that to drop the old axle out and press the new axl...

Pics to come of the new found problem and solution of these new torque arms. First glances So far, these things are freaking beefy! They are just about as thick as the ebikes.ca torque arms. It took a tiny bit of dremmeling to fit the axle, but its as tight as the ebike.ca torque arm. The one proble...

At 40 amps and 20s lipo, you won't be overheating the 4080 as fast as the 3540 lol. It's the best upgrade for the money from where you are at currently. I upgraded my 3540 to the 4065 and it gets warm but not as uncomfortably warm as the 3540 got. You may find that the 4080 consumes less amps at the...

The crown is now on the simulator. Check it out. It doesn't perform much better then the 5400 series motor and that with all the extra copper and wider Stator. I would say, go for the cromotor. Currently the cromotor is cheaper and you get more motor then the crown.

I think the short one will put more stress on the caliper mount because its shorter and mechanical advantage being polar oposite against the Caliper, but I don't think it matters because the caliper bracket is designed to lock up the wheel and stop it. But wait untill you get it. They are super san...

Lipo's like to be stored in cold climate at 3.8 volts and nothing plugged into them.
I had mine stored in NJ winter climate for the entire winter...... No drop in voltage what so ever. Of course the controller was unplugged from the battery.

Trackman, I don't know why you waited this long to bet Mig torquarms. Get the one in the pic, with this arm design, this one puts the least amount of torque forces on your brake mount and maximizes mechanical leverage against the axle from spinning. Rick hehe. Yeah, about that :mrgreen: . If I don'...

- at 00:20, under 65A (5.6kw) load, delta V hits 0.125V (turnigy 25c cells (17-20) sag to only 4.05V, but zippys sag to ~3.98V avg? [3.93V to 4.1V judging from graph]) Yessir. I made the switch from zippy's to turnigy's and they do sag a little less under load. I also can tell I am getting a little...

I wish I had a better/ more practical way to charge 24s of battery's to get the motor up to 40mph. 24s 10ah removed from the bike as was re-doing some wiring. http://i189.photobucket.com/albums/z313/sacko_vit/6E3925E3-F85F-41FE-94B0-67062B024F84-3319-0000017A18D0A2B9_zpsbaa08cb6.jpg 24s Charger £10...

Uh-oh.
Ruining your new battery already I see? Looks like you got yourself a runt cell. Don't lipo's start differing in voltage past 3.7 volts, so that one cell being a lot lower then the others is expected.
No video of your commute?

I did a small batch run for a right arm but it won't fit all frames. I'll pm you a scaled pdf you can cut and measure in your frame if it fits them pm me later. That one is made out of the same thickness and metal except it is open and doesn't interfere with the derailleur. I'll post some pics late...

Yeah man. I think I would've wound the motor in the time it took you to get started .
Please keep us updated. The suspense is killing me.

Hey Orlando. ANy news on how much power one can put through these torque arms? After snapping a hose clamp on one my torque arms, I think its time for a much needed upgrade .

Does anyone know if there is a light that goes on or something when a hall fails and the controller switches to Sensorless mode?
Other then the ye olde' stand your bike at the base of the hill and see if your motor will advance?

I think you woul be fine upping the voltage and lowering the amps. If the 4065 is getting hot, maybe you need to limit your WOT to just a few every half hour or so. I bet this thing rips with that much power 8) . I was thinking about getting a lyen controller, but i just snapped one of my torque arm...

I hear the training is really difficult. Must be part of the occupation lol.

Also forgot to post a picture of my brother and sister from our trip up to Maine :P Looks like there is another form of police around Rick. You guys might be in for some competition from the fun police, or more adequately named the Sex Police :mrgreen: Sex Police.jpg Sex Police2.jpg 'ME RIC CA 8) :l...

Thanks for the info Trackman, its especially useful at this stage with no 40xx motors on ebikes.CA/simulator . Do you know the weight difference? I suspect its 3kg or so. In the precious pages in my thread, I made a point to weigh the 4065.... With a seafood scale so I know its accurate :mrgreen: ....

Looks good your build! And nice motor! Any diffrences between HS3540 and HS4065? Rix just threw some rock hard facts at you. How do you feel, enlightened? :D Now it's my turn to throw some facts about how each motor handles. The 3540's no load speed on 20s is around 60 mph so on a downhill section,...

If you are going to get a 4115 fet controller, I highly recommend getting one of Zombiess' 4115 controllers or seeing what you can do about paying him to match the fets and send EM to lyen or someone to make a controller. That will help with reliability in your controller setup.

I see you got your cover off. The holes in the center of the stator can you see the other side cover through them?. If so, just drill vent holes without disassembly further. Also, vacume out the drill shavings completely. Frill out the cover you have removed, Spray a bunch of T9 Boeshield in there ...

At full power, my voltage dropped from 82v to 58.2v :shock: A 24v drop at 148.5A. That's 3.5kw heating some shit up! Dammit I feel short changed. I want that to go to my wheel as well! I dont think it works like that :P Thats just voltage sag from the high demand of power from the battery's not was...

Trackman417, Where is this ian.mich located? Web address? I have almost $600 in my two lipo chargers, a Thunder Power 820 and a Hyperion Super Duo so ditching one to get a bulk charger only makes sense to me. I'm too lazy to pull and charge 12 packs and have been toying with going to 16 for a 24s4p...

How's your tyre pressure? That gets me often as I use a hand pump and its hard to tell what the pressure is without a gauge. Edit... quote to show wtf were talking about ;) Needs some adjusting :roll: . The tire pressure is pretty good since I rode these tires for damn near 700 miles and almost no ...
