I haven't seen on the thread anywhere where one has specifically mentioned the D/O width so best to check.

There are very very few hubs to fit 74mm width D/O's and the one I mentioned is one of the very few. The same motor in silver is sold by Bmsbattery as the Q70, both are 36v 250w and are Aikema's.

Any generic BB with an English thread will work, avoid press fit BB's, Carbon bikes and eccentric BB's. Typically a 68mm BB is preferred though one can get away with 73mm BB. One other thing to watch out for is the rear horizontal stays esp ones that go from a narrow profile at the BB to a wide...

It is a DJ 70xx series connector there are many 100's of designations. That one looks like a six terminal block used for sense wire connectors which is a DJ7061- 2.8- 21 used widely for generic China ebike controllers. The 2.8 is the pin pitch. One can buy differing terminal blocks for...

Tbh messing about adding more magnets isn't worth it, more magnets may even cause issues depending on the controller type.

The colours to some do seem odd and anyone who knows no better would simply have joined R/R , Y/Y & B/B and assumed the PAS as faulty. 5v is nearly always Red or some times Brown. Gnd is usually always Black but if no Black is used then Yellow is used. When one sees Black and Yellow on the same...

It is for 100mm drop out width.

Switch is likely for a reset. Reasons for not charging a few; SOC may be too high, try discharging a bit more to see if the charger charges. I have a generic charger that won't charge if SOC is too high on a 48v battery. Internal charge fuse if fitted is blown. Cell groups or a cell group is...

xf07 is 100mm drop out. For 74mm drop out width one has to us ethe AKM74sx from topbikekit.

50 cycle are defunct though they did start up again under another name and washed their hands of previous buyers.

Ah but you have been helpful Chris. One has highlighted a source which may be very suspect in the least. It is up to the individual to decide.

Even worse then the pic SW posted, good reclaimed cells may be ok if all from the same source or decommissioned battery but still a risk unless the provenance/history is known.

ES member Turnich in Lithuania or the like offers used cells /packs for sale in a very much similar state as 2nds as does Nkon, the former has access to supplies of defunct Bosh batteries. One expects some or most of the packs are from batteries which have been bricked or ones that are...

What do you call a competitive £££ ?

The C961 lcd is usually a Bafang BBS display though looks like it has software and programming to suit the Lishui controller, you will need a Lishui compatible lcd for all features to work otherwise you will get limited info and likely maybe PAS1. I have an old BBS blown controller and will...

ebike batteries don't use protected cells as that is what the BMS does.

Lithium chemistry batteries don't need to what some call 'conditioning', the old Nicad's had memory affect and possibly Nimh but they are history for ebike use.

If no Red LED is showing then it isn't seeing 5v, either the connection isn't fully home or the wiring sequence isn't correct. These are easy to fit but if the wiring colours don't concur then thye simply don't work. Is this a retro fit or new PAS fitted ? Show us a pic of the wiring at the...

I've got one and have blown two controllers :( and have had PAS issues, it also has its issues. I really need to dig it out again and try the KT on it again.

The steel used is soft but the main issue is the breakage is always on the drive side approx. 2cm in where there is a groove for a circlip which I believe holds the bearing in place, the extra bearing use dis to try and stop any axle flex but isn't the answer to prevent axles snapping.
