Re: Hi, TSDZ2 any coaster brake users? BBSHD build thoughts

Just came across this thread regarding the coaster brake model. I have a couple of "non" coaster brake versions of the TSDZ2 here in my shop, and just tested whether your idea that any TSDZ2 would work with a coast brake. The pedals engage the chain ring normally in a forward rotation, but freewheel...

Re: Bafang BBS01 Found It!

Figured it out. The internal hall sensor connector was loose. It looks like the connector was not completely seated when the silicone was applied to lock in the connector. hall_connect_1.jpg hall_connect_2.jpg hall_connect_3.jpg Bike works great. This was just a minor assembly glitch, but shows the ...

Re: Bafang BBSxx - fault finding and fixes

Yep. Good catch, Tom. The BBS01 probably has a much lower HVC. Try running it on 42V. Max. Overnight I started questioning the accuracy of my 20 year old Craftsman multimeter. This am, I pulled out one of those freebie Harbor Freight multimeters. Sure enough, the Craftsman apparently went haywire. ...

Re: Bafang BBSxx - fault finding and fixes

Yep. Good catch, Tom. The BBS01 probably has a much lower HVC. Try running it on 42V. Max. Yeah, you're right - that is too high! Strange, as it's a "test battery" consisting of three new 12V 5AH SLA's running in series. I just put it together. I'll take the pack apart tomorrow and test the individ...

Re: Bafang BBSxx - fault finding and fixes

Another possible cause of the turn on and then blank screen could be a poor battery connection. Check the wires and connections to the battery to confirm you are getting a solid connection with proper voltage between 42V-60V. Once I start pedalling the bike, the display comes back on, but there is ...

Re: Bafang BBSxx - fault finding and fixes

I made a rather protracted search, with the poor native engine, and found nothing. Neither did an exhaustive google search, limited to english. Where are you located, perhaps you would be lucky enough to have another user near by and find that it is a C961 problem. I didn't have error code 8 but I ...

Re: Bafang BBSxx - fault finding and fixes

Just installed a BBS01 350W 36V C961 Display and turned the unit on. Came on momentarily and then displayed a blank screen with er 8 at the bottom. Configured the system including wheel size, number of PAS settings (9) and plugged in the thumb throttle and brake levers. Speed sensor blinks red when ...

Re: GNG, 1000W 48V BB-drive, $400

Got my sheets and spacers from LightningRods today. Pure eye candy.The cut edges are smoother than the GNG plates.
Anyone know of a good company in the US that can plate the sheets to match the GNG sheets? I'm assuming they nickel plated them.

Re: GNG, 1000W 48V BB-drive, $400

Several sources have been discussed in this thread on where to buy the GNG drive. What is the best source, considering a balance of price, shipping cost and receiving the package in one piece?
