Re: NEED HELP PLEASE HUB MOTOR PROBLEMS

Hummmm. This is a funny one...And I don't mean "funny ha-ha". I don't know what motor your are running because you didn't tell us the make and model. My first guess would be that the gear attached to the motor axle isn't turning because it is striped on the inside of the gear (not the outs...

Re: Kids 500w fun bike keeps cutting out

Seems plausible from where I sit. Make sure your nickle strips and other connecting wires can take the current.

Re: Voltage selection

Sounds good. Just be sure to set the low voltage cutoff properly so you don't damage your battery by over discharging it.

Re: Can I and should I do this

I've re-laced 3 direct drive motors that came with 12 gauge spokes and used 14 gauge spokes. Also one geared hub motor and rim that came with 13 gauge spokes replaced with 14 gauge. The J-bend is of course offset in the larger hole, but wouldn't be able to pull through. I've not noticed any problem...

Hey Bikejunkie! Welcome to ES. From one "I'm older" to another, the answer is yes, you can put 20" wheels on a bike made for 26" with some caveats. How did Ross Perot so famously put it......."The devil is in the details." It goes like this. Obviously you will need brak...

Re: Kids 500w fun bike keeps cutting out

Looks like you might have weak cell groups. Leave on the charger for 24 hours to see of they fully balance. Then check them again and write down the results. Then, as suggested, run it to LVC and measure the cell groups again to compare the voltages of the cell groups when charged and at LVC. You wi...

Re: 5 way lights/ indicator/ horn switch help

First, how can you get the wiring info from the seller? They must have some way for you to access it. Second, get your DMM and start testing. Do this. Assuming that the green wire is a ground wire, and maybe it isn't, but lets assume it is. Set your DMM to continuity and connect the black lead of yo...

Re: Kids 500w fun bike keeps cutting out

Leave the battery to charge over night and then ride the bike again. Meter the battery voltage before you ride. The point of this is to be sure all your cells are balanced and that one or two aren't triggering a low voltage cut off. You can also find the balance leads of the bms and meter those to f...

Re: How to dissasemble a Mxus rear hub?

When you resemble it, mount the gear sided cover to the wheel first then use two hands on the axle when reinserting the stater and axle. If you catch your finger in between the stater and magnets you will be very sorry. :oops:

It's not that simple. Is your battery rated for 100A continuous discharge? Is your controller rated for 100A continuous discharge?

Re: ideal front fork for street: Speedway style leading axle?

Just so long as it doesn't constantly bounce your front wheel off the ground, hopping and skipping all the way. Some traction is needed.

Unless you plan to pitch your bike sideways and go left, if you know what I mean. :wink:

Re: mtx 48v controller can it handle 52 volts

The answer is probably, but with no guarantees. The only way to know for sure it to know what voltages your controller capacitors and mosfets are valued for. To check that out, you need to open your controller and look at the components and figure out the values. The capacitors have the value printe...

Well, I am not familier with your BMS, but sorry to say your story is an old one around here. BMS's being connected to a battery for a long time and draining the battery has happened many-many times. As you surmise, disconnecting the BMS for battery storage is the way to go. Either by switch (make s...

Re: Hub motor suddenly feels like a rubbing tyre..

When you said it was fine, what did you check?

It could be a bad baring, a loose magnet, a loose axle, a misaligned brake rotor, it could be a lot of things.

Can you give us more detail of what you checked?

When you say limited performance, can you give us more detail. Did it run smoothly without power, did it jutter around, what do you mean limited power?

Also, how do you know your phase wire / hall sensors were in sync?

Re: Are generic Chinese controllers and throttles non-adjustable?

Inexpensive generic controllers are usually modified sine wave (trapazoid wave) and are generally not serviceable much. If you want smooth starting a sine wave will give you more of that depending on your motor / controller setup. Bluetooth controllers are more programmable, and yes, more expensive....

If they can not take 5A, then at best you overheat them and degrade them. At worst you set them on fire. Any way to figure out the types of cells they are? Manufacture and type of cells?
