small front hub motor with disc brakes can I use rear motor?

[frankfrederick]

Hi folks, my first , hello to all of you

I wish to ask for an advice,

I want to buy a small hub motor approx 350W for front tyre, It needs to be silent, I have decided for q100 or q128

But they dont have disc brakes in q128 versions,

do you think that its possible to use rear motor and put it in front ?

No... It will be too wide to fit.

This is perfect:

Look for the Bafang G311. 100mm spacing and disc brake. Geared and quiet.

 

[frankfrederick]

Which one would be the strongest?

Silent and relatively strong light weigh and front with disc brake

 

[frankfrederick]

Btw I have Electra straight 8

That bafang looks really good!

Depends: Can you change the fork? A fatbike fork may have the correct width for a rear hubmotor.

That's how I'm going to use a rear hubmotor on the front of my SB Cruiser trike (in addition to the two rear motors it already has in back), eventually.

How about bafang g320? Or g360?
They look like a new motors really cool

As AW said, measure that front fork. Many fat tire bikes have the same front fork width as a regular bike rear. 135 mm Yours might be that size, or it could be 100mm standard front, or it could be something non standard. If its not 135 or 100 mm, you will be limited to changing the front fork. ( to standard 100mm, and a narrower tire.

If your fork is 135mm, measured on the inside of the dropouts, then you do need a rear motor for the fat bike front wheel. And many of those come with disk. You mentioned wanting power and quiet, to me the quiet really points to a direct drive motor. They are heavy, but on that bike a DD front motor will be ok, its not a flyweight road bike.

ALL the geared motors make some gear noise. Not a big deal at the lower speeds, but at 25 mph cruise, they make a very noticeable high pitch whine. A DD will also make noise, but a lot less.

So far I like g311

Are these available only in Canada? They want 300usd for shipping to Poland... Too much...

What controller is best for use with that motor?

 

[frankfrederick]

They offer cycle analysis ca3dp v3 for that motor and controller.
It looks so complicated....
I would rather use something simple like lcd6 from bmsbattery.
What do you think? Should I worry about the complicated setting of that cycle analysis ?
