Where can I find a Bafang Hub motor (BFSWX02-10) for my Juiced CCX?

[Jerry Mike]

Does anyone know where I can buy a Bafang (BFSWX02 - 10) hub motor for my Juiced CCX. That is the motor that the bike came with and I would like to replace it with a new one. Any help would be appreciated.

SWX02 is also known as G020, I think that's the new name (designation).
Are you specifically looking for 10T winding?

Yes, the stock hub motor on the Juiced CCX ebike shows BFSWX02 (10) labeled on it. It's a 750 watt motor. It would be great if I could replace the motor with a identical motor.

 

[Jerry Mike]

No, Juiced has 350W motor over boosted to 750W. (Unless they changed to 500W at some point, in this case, it would be 500W boosted to 750W)
Also winding can be changed depending on your preference.

Thanks for you input. I noticed on line Bafang has a RMGO20 which (according to them) is the new name for BFSWX02. Maybe that's the correct one. It did say 500/750 watt.
Does the Juiced CCX hub motor use a "free wheel or cassette" for the sprockets?

 

[Jerry Mike]

GBK (Green Bike Kit) offers the "500W/750W Bafang rear hub motor SWX02/RM GO20" for $139.00
The core of that motor might fit in my existing Juiced CCX motor. Last week my existing motor started slipping (bad clutch or ratchet mechanism, what ever you want to call it) and I thought a new core would be the best thing to put into it to get things up and running.

 

[Jerry Mike]

I doubt this is 750W rated motor, I think it's a typo.

If you click on the spec sheet, it says 250W/350W.
Anyways, it can easily handle 750W so it's fine either wya.

Yeah I think it will likely fit the existing motor. So all you have to change is the core.
It doesn't say anything about the winding though.
If you want the 10T version, you might have to click the smaller wheel size.
I don't know if they will give you 8T or 10T.
If you click larger wheel size, most likely you will get the 13T, but you would need to ask them and double check.

My original motor (BFSWX02 (10) indicates it has a 10T. Is there an advantage to get a higher or lower winding than the stock version?

 

[Jerry Mike]

In general,

Higher T will give you higher torque, low rev. (often used on larger wheels)
Lower T will give you higher rev, lower torque. (often used on smaller wheels)

I see. Thanks for your input.

Here are some info I found on HillEater (Juiced distributor in Canada):

• 11T Motor windings with 48V, 700C wheel will give about 40-45 kmh top speed. (25-28mph)

• 13T Motor windings with 48V, 700C wheel will give about 30-35 kmh (18-22mph) top speed. If you want 45 km/h (28mph) you need the 10T motor
• A higher winding count makes the motor turn slower for a given voltage, but with more torque and higher efficiency climbing hills. If you don't need the extra speed of the 10 turn motor, the 13T is a good choice.

Thanks for that information. I think the 11T is as close as I can get to what I had. That looks like the best choice for me.

This was useful - thank you. I had a BFSWX02 48V500@ (13T) on my 2017 Surface604 Rook. Surface604 shipped me a replacement, but it was an 11T, and has noticably less hill climbing torque. I live in very hilly North Vancouver, BC, Canada, and the 11T cuts out on climbing some of my steepest hills. The replacement is C020 500DC 11 - which I take to be 11T.

FWIW. Also wanted to thank. you two for the info & discussion - good learning for me.
