Re: Custom Motobecane Ebikes with Premium components

Looking at options for my wife who needs something with a 26-27" standover. Thanks though.

Re: Custom Motobecane Ebikes with Premium components

On 29er #2 - they offer a 13" frame. Can your battery and controller fit this small of a frame?

Re: Leaf / leafmotor / leafbike high efficiency 1500w motor

I got it all sorted out (the wires inside the cable that enters the adaptto are not standard hall colors - blue wasn't connected to anything and I needed to use Orange). It auto detected and seems to work. Just not as impressive as I thought it would be. Anyone running a 4t on an Adaptto mini-e (unl...

Re: Adaptto Mini-E/Max-E Owner's Thread

So I picked up a used Mini-e recently. The hall sensor plug was chopped off and the wires were bundled inside some heatshrink. Unfortunately most of those wires were still stripped bare and shorting together. I didn't power it on this way but was told that this was cut off and ran on a sensorless mo...

Re: Leaf / leafmotor / leafbike high efficiency 1500w motor

I've got 10 coming from Digikey. I pulled my motor apart and tested the halls individually. It seems like all three are flaky - I apply 5v and when I pass a strong magnet over, I only get a small signal between gnd and the signal wire of each, but I get full switching between +5 and signal, but even...

Re: Leaf / leafmotor / leafbike high efficiency 1500w motor

Well it looks like I've probably always had a 'bad' hall in my leafbike motor. The performance at 3000 watts was always 'meh'. As it was m first ebike experience, I wasn't sure what to expect until I build my wife a 1500 watt ebike that has much greater acceleration. Now it makes sense. After a frus...

Re: Leaf / leafmotor / leafbike high efficiency 1500w motor

Thanks for the reply. I've tried many combos of those settings and phase wire arrangements and consistently get a hall 'e1' error.

I'll keep fiddling with it and hope something works or just sell it and go back to what was working before.

Re: Leaf / leafmotor / leafbike high efficiency 1500w motor

I just picked up an Adaptto mini e and am having little luck getting it to work with my 4t Leaf motor. I can run it in sensorless mode, but autodetect always fails and gives a hall error code. In the health monitor, when rotating the wheel forward, I see halls 1,2,3 in order. Sometimes it reports ha...

Re: Where to buy parts for EEB

I'm in the same boat. Need a new plastic top tube cover. I would be worried that there are possibly several manufacturers of that frame so maybe going back through Em3ev might be best?

Re: Frame for sale SEKIBIKES Frame 2017

Yeah, the swingarm worries me too. It would seem that its design would require the Axle to share a higher than usual amount of certain loads - compared to a typical tubular (be it box or round) swingarms. They could certainly mitigate this somewhat by adding truss elements along the outsides of each...

Re: torque arms (do I need 1 or 2 of them?)

If it is a steel frame and you stick to 1000 watts and don't use a lot of regenerative braking, then one should work. If aluminum and/or regen, then I'd use two.

drawing 70amps through a em3ev 9fet4110 I am no expert on these controllers, but 70 amps really is a lot of power for a 9 fet so my guess goes to blown controller.

Re: Ebike conversion 600$ budget

Isn't it the worst hearing people suggest just pedaling? Actually, it's worse seeing people go out of their way to be lazy sacks of crap, when they're unwilling even to commit enough resources to do it successfully. It's the typical car driver approach to life, for sure. Therefore it's both common ...

Re: Leaf / leafmotor / leafbike high efficiency 1500w motor

Does it sound like a bad bearing? If not, disconnect the phase wires from the controller and check again for resistance. If the rolling resistance disappears, you have cooked FETs in your controller and they are shorted.

I know this isn't the answer you want, but Hobbyking will randomly drop the price of various packs. Keep checking as often (daily?) As you can and you'll run across good deals again.

FWIW - my steel chinese electric enduro bike weighed in at around 80lbs on the bathroom scale with 12s 16ah lipo packs ready to ride. I was surprised to see it weigh so little. Makes me wonder about those scales.......

Re: Are Leaf 1500W and Edge 1500W the same motor?

Not that I am aware of. The 'new' leafbike 1500w, as I understand it, was larger phase wires (which mine didn't get when I ordered it). I believe it still uses a steel stator. Lamination thickness is the same between the two. Not sure if thr Edge achieves the same efficiency as the Leaf though. Sent...

Re: XS Trek Marlin 5 650b Conversion

Ok, I figured out the 7 speed is just a shade too wide for the axle in this setup. I had to turn down a washer so that it would fit inside the freehub against the axle shoulder. Noise is gone.

Received the motor/wheel kit today, but unfortunately it makes a loud rubbing sound. It sounds like from behind the freewheel. I'm guessing it is a bearing but haven't dug into it. Installing washers doesn't help and I haven't cinched down the axle nuts yet. Hasn't been powered on yet either. I sent...

This will be a conversion of my wife's Trek Marlin 5, 13.5" frame, 650b wheels. I've ordered a 1500 watt hub motor from Leili with the color TFT screen and RFID keys. My wife isn't interested in high speed, but wanted something so she could ride with me. I'm somewhat concerned with battery and contr...
