Kepler, you dont do yourself justice with your average snaps.

Marc S. said:Hi Kepler!
Very nice build!
I run the Bafang SWXH (and Bafang BPM II) currently with 13s to 15s LiPo battery and 35A controller in my ICE Sprint recumbent trike and had clutch problems with both motors as well.
Since I filled 50ml ATF with a big syringe through the disk brake screw holes of the SWXH the clutch problems are gone. On top of that he motor is quieter now and I think freewheels a tad better. http://endless-sphere.com/forums/viewtopic.php?f=2&t=37972&start=375#p731095
I think the sprang clutch of the Bafang SWXH doesn't even get enough lubrication with the stock grease filling at its rated 250W for a longer period of time. My SWXH clutch started acting-up infrequently after 1000km or so when still run off a 10s battery and 15A controller.
No, running in an ATF oil bath, the more or less frequent sprang clutch lock-up is a problem of the past. Since the SWXH is better cooled as well I'm much more confident to use my ICE Sprint as my daily commuter with 14s battery at up to 45km/h WOT. It gets quite warm, though.
Kepler said:Thanks for that.
I have used tried the oil thing in my BPM and made a hell of a mess. Not too keen in re visiting that. I may have got a bit carried away with the ATF though and put closer to 150ml in.
If the clutch locks up on the SWXH again, I might take up your suggestion ATF and keep the level to 50ml as you have suggested. Will see how it goes
Samd said:Thinking of doing this to my BPM - any side seals necessary, or just keep it to below 80ml so it stays below the axle wire exit?
Sorry for the threadjack Kep.
Hi el walto,el_walto said:Not sure why hobby king lists 2 separate weights per pack.
Kepler said:I am really pleased with this formula and am considering building a similar bike for sale. Main difference would be an Aluminium frame rather then carbon although would be happy to build it in carbon if requested. This is the donor bike I am considering. http://www.cellbikes.com.au/2011-CELL-X-2-City-Bike?sc=21&category=12627
Price wise, I think I could make it worth my while for around $3,000.00. Any feedback would be appriciated.![]()
Hi KeplerKepler said:Thought it was about time I fixed the seized free wheel in my geared hub today. Ended up being quite a job. Not so much replacing the planet gear assembly, but just getting the motor apart.
This geared hub has a screw on cover that has 3 recessed holes used for disassembly using a specialised tool. I tried getting it apart with a C spanner and strap wrench to hold the motor, but not a chance. Decided best bet was to get serious and make a proper tool for the job. Here is what i came up with.
The Aluminium block attaches to the disc brake mount so you can hold the motor securely.

A big shifting spanner or pipe is then used for plenty of leverage
CORKY said:Hi Kepler,
I admire your workmanship.
I am looking at doing a similar build on my aluminum hybrid frame,
but may go to a road bike soon.
Where did you buy your 201 rpm Bafang motor ?
I'm in Los Angeles, so I was wondering if you have considered selling a kit without
the bike including the motor, controller, and all other electric parts with full instructions, of course.
You could even exclude the wheel, batteries, and Cycle Analyst for compact shipping and better pricing.
Personally, I have a Cycle Analyst already, but the former model.
Can it do the detailed split info between the motor and pedal inputs, or is that reserved to the model 3 ?
If I get to it first, what generic controller do you recommend ? I could go with a Lyen, as he's close.
I would like to use the RC LiPo batteries, but in the interest of safety, what high quality
charger, BMS, or other monitoring systems do you recommend ?
Safety is senior to money on these.
I'm good with mechanics, but a little shy in the electrics department.
Where can I get a detailed wiring diagram for everything,
including the controller, BMS, charger, 3-position switch, and C.A. ?
Thank you for the help.![]()
I hear that..thanks Kepler.Kepler said:Hi Todd,
The tool would cost you twice the price of a new moto![]()
Is there any chance you would make another side cover removal tool and sell it
Bafang bldc hub engines opening tools [sic] appear to be available from greenbikekit.com for most of the thread on cover motors. They are not cheap, but still less than 1/3 the price of a motor. They also have gears, clutches, and sidecovers as spare parts. Which is pretty cool really, I don't know any of the other usual suspect vendors offering repair parts.Kepler said:That tool took me half a day to make and another half a day running around getting the materials. The tool would cost you twice the price of a new motor for me to make it for you unfortunately
