In case you're not aware, power delivery can be very finely tuned on the bbs0x range via a programming cable

Another drive failure in my spare bbs01b (motor #2). This motor was installed exactly as received from an aliexpress supplier, with no mods done other than applying mobilgrease 28 to the large gear. Following stripdown the following was observed: 1. Splines damaged at two positions, one area...

Which cassette should I use with the q128c? Can I use my tried and trusted PG1030 http://www.chainreactioncycles.com/mobile/sram-pg1030-10-speed-mtb-cassette/rp-prod67864 Or does it need to be this version...

I'll take the lot if still available

Thanks for the info Nealh. Is there any need to keep the display installed once the P&C parameters are set? My experience with the bbs01 is that a display on the bike attracts the wrong kind of attention from the public! The bbs01 needed a slight tweak to the controller wiring to allow...

Thanks all for the information. From an installation point of view the 09 controller looks the easiest to mount, I'm thinking way low down, just above the bottom bracket & behind the seat post down tube, with the wires exiting vertically downwards. Rivnut or cable ties, depending on mass, to...

99% of my riding is on the flat, so happy to sacrifice torque for mph. Here is my battery: http://eclipsebikes.com/product_info.php?products_id=144 Would the 36v 328rpm q128c be the optimum choice? Donor bike in question, with bbs01 fitted (about to be removed)

I'm already riding a modified Boardman 29" bike with a bbs01 - at 18amps I can hold 27 mph foc on the flat. I'd like to remove the bbs01 and experiment with a rear wheel hub drive to achieve similar speeds, but would like to use the same 36V battery I already own (17.4Ah Lithium Ion Frame...

Changing pas level on a touch screen phone?

My experience, front suspension needed over 20mph

Roughly every 1000 miles or so the motor begins making mechanical noises - a fresh application of mobil 28 to the large gear behind the chain ring quietens things down again

How about this as an alternative to the 29e 6p pack? Any opinions? http://s.aliexpress.com/nM77nYFr

Understood As the MOSFETs appear ok, is there a different, repairable controller specific failure that would result in the controller not switching on (and hence no +5v to the display), despite the controller being fed the correct 'switch on' voltage from the display?

LCD switches on my good controller, but not the spare controller. I've repeated the y/G/b resistance check after grounding Batt +ve to -ve each time: against the -ve I'm getting 10k ohm on all 3 wires again. Against +ve, each wire slowly rises to open circuit, behaving consistently

Have you checked the 'B' dimension? Distance between upper derailleur pulley and cluster should be 6mm approx I believe. You can't measure with chain in place so use dead reckoning Set your chain as short as possible too.

Thanks, I'm measuring 10k ohm for green / blue / yellow wires to battery negative, so I assume MOSFETs are intact?

I'm Experiencing a similar problem (bbs01, battery fully charged at 42v) with my spare controller - see picture below Bearing in mind the system works perfectly with my working controller, could anyone help to establish if my spare controller is permanently fried? I'm measuring 0v on the +5v...

Just persevere The dust cap is sacrificial - it's just a rubber coated steel washer. Once the rubber is completely removed, the remaining steel part can be removed with a magnet. Following a similar repair, I ran without a dust seal whilst waiting for gbk to send a spare seal
