Ah! They are in every house here, and 9v batteries are very common.
Yet, if you don’t have a 9v battery, use any other combination of batteries to make 5+ v

Re: Are these cheap "sinewave" controllers really sinewave or just simulated?

Most controllers that are sold as sine wave are not real sine wave. Look for field oriented controllers.

Re: I need help, as i dont have anywhere to ask, and no one to help me

Yes. You need to supply the halls with 5v and rotate the wheel to test. Each hall sensor does return a signal for one phase. It doesn’t need to be 5v but not too high of course. The test can be done with a 9v smoke alarm battery without any damage. https://electricbike.com/forum/forum/knowledge-base...

Re: I need help, as i dont have anywhere to ask, and no one to help me

If you have no return signal on the three of them, the problem is probably in the 5v circuit (red/black wires). One of them might have been damaged, or cut.

We see nothing of your test procedure on the vid. What source did you supply the 5v circuit with?

Re: I need help, as i dont have anywhere to ask, and no one to help me

It is very unlikely that you fried 3 hall sensors at once. Don’t test them plugged to the controller. You want to know if halls and wiring are good in the motor. If they are OK, then it will be time to identify the cause on controller side. If they are not, it will be time to open the motor to see i...

Re: I need help, as i dont have anywhere to ask, and no one to help me

If you have a hall sensor fault, it is unlikely that your controller is fried. Test the halls at motor exit, and if one is not returning a signal, open the motor and check the wiring before ordering replacement Honeywell hall sensors. Sometimes it is only a rubbing damage to a small wire. Easy to re...

Re: (What is) The Best Damn 500W (front) Hub Money Can Buy?

:D Depends of what you are expecting. The Leaf 1500 is a very good motor but I’d say a tad too big and powerful for a front build. I believe most who are building with a front hub prefer using a smaller geared hub. Best is to avoid a heavy front wheel, if you value handling and nimbleness. If you ar...

Re: Thru axle to Drop out conversion? Santacruz Bronson

Hub builds are different animals. They don’t ride as much as a bicycle, compared to a BB drive. If you want to climb without shifting gears, at a much higher top speed, then a heavier hub build is a must. But, it won’t handle like a bicycle and sure not a good jumper. Riding the mountain trails with...

Of course, we are talking DIY. Many would not hesitate to learn building their own wheels if they knew that expansive equipment is not a must. This is a recurrent problem for ebikers, to have a hard time finding someone to do it locally.

The same spoke roller head can be fitted to do 14 and 12 ga. You don’t really need the machine if you mind the money. I have used a variable drill successfully before.

Re: Assembling a safe fast ebike

Shortest motorcycle braking distance is the Aprilia Tiono. I believe it is possible to beat it with an ebike. I beat all motorcycles that I tried for braking, but I am still at a longer braking distance than the Tiono from 60 mph. Example in slow motion:

Re: The best universal crimping pliers

I have the crimping tool for Andersons, and one cheap multi-tool that fits small bullets and spades connectors. Turned out I never needed any other. There is some simple logic into using the connectors for your crimper, instead of buying a crimper for every different connectors that you meet.

I shop for batteries every year for a decade, and never seen as much variance as this year. Various Li battery chemistries and quality are making as much difference as 5 to 1 for equal voltage and capacity.

Re: toronto Bafang Hub Motor

There must be many ebike shops in Toronto that can fix your bike. Yet the cost of repairs on a hub motor are often higher than the cost of the whole motor on aliexpress.

Best is to fix it yourself. Hall sensors are cheap, and the controllers on commercial ebikes are usually pretty cheap too.
