I’ve just finished repairing a friend’s battery (faulty BMS) and I’m re-assembling it but I’ve forgotten which way the output pins are arranged! It‘s 2 pin output, + and - Is the negative - pin on the key and charging socket side of the case or the other side? Could anyone with one of these...

have you approached elifebike2010? They are PSWpower.

PSW offer a DDP service (delivery duty paid) which avoids paying approximately £40 to the Post Office. Most of the other sellers seem to offer the same but in practice don‘t. Before the virus, the price for an 8 pin 48v 750w motor with throttle was £250 from PSW, now £270. To have the...

Any of the suggestions will work but your bigger problem is the gap where the power cables exit the halon case. Moisture up there can be lethal. Fill it with RTV silicon.

I took one of these things apart and I thought they were just a simple micro switch and did not require 3 conductors. They can be adjusted; the brake handle depresses the, what I think to be microswitch. The switch might be on the cusp of making contact and with vibration etc etc. I do have a...

The standard motor does not give you a torque value but if 98 appears on your display, this could be the speed sensor set too close to the magnet?

The “noisier” video might be an older version of the TSDZ2. It looks to have a silver spider. I mentioned either here or elsewhere that the latest motor with the black spider was much quieter and smoother. I had a thought that the manufacturer had cheekily implemented the best bits of the open...

TSDZ2 will come with a 42t chain ring. It is heavily dished to fit round the housing and I don’t believeve there is a chainring with fewer teeth which will work at a sensible price. A single chain ring with a 11-46t cassette (10 or 11 speed) is a better bet. Multiple magnets aren’t necessary...

In the pic you’re looking forward from the left hand side. The dreadfully drawn red arrow points to the clamp bolt which is passing through a rather odd shaped washer sitting in the junction of the two stays. With the TSDZ2 there is a clamp bolt which prevents the motor rotating due to the...

I presume you are thinking that I chamfered the housing? No, I didn’t! Its a permanent feature and is there for that purpose. The spacers just lift the frame off the chamfer/motor.

The Bizango proved to be well worth converting with a TSDZ2. By far the best one I’ve done and is a real delight to have but .... I needed 2mm of spacers of 35mm diameter which, unfortunately, increased the chain line. Any thoughts of keeping the front derailleur were out of the question as a...

It’s very easily done. ES has one reference to this happening by one of the US importers. It was described as intermittent.

There are at least two differences. The spider which attaches the chainring to the main gear is all black instead of a silvery colour - you can’t mistake that. The other is the main gear cover which has rather more square edges and feels stronger although whether it is or not remains to be seen...

Fortunately I’ve not experienced such a problem. There have been difficult to diagnose problems which have come from incorrectly connecting the connectors. What happens is one or other of the pins in either a 5 or 8 pin connector are bent out of engagement - easily done. It would help to know...

When? I’m in the middle of my 5th TSDZ2 conversion, this one a 29er and I could do with one! I make them for friends and family. Apart from the first which was 36v all the others are 48v 750w. Over the last 2 years the quality has improved substantially. I used to open them up before they were...
