You're being far too modest! And I should hang my head for being so unobservant.

vfr400 - bravo! You were perfectly correct in your diagnosis, pretty good seeing as I am the best part of 800 miles from you. Being a bit more mechanical than electrical, I instead adjusted the brakes at the levers, so as to ensure the 'no brake' position meant that the microswitches were...

Thanks again, kind of you to take an interest. As a 75yo Physicist I should have picked up how these bikes work much easier than I have. But ...... Anyway, I'll have a look at the rats' nest that is the tangle of wires and connectors.

Thank you vfr400. I am a newcomer to elec. bike technology and am struggling to understand some aspects. What are brake switches? I am guessing that are to do with some braking mechanism of the motor? Maybe the intention is to make sure the motor cuts when you put the brakes on, so it is not...

The lights do nothing when the power is requested - they stay on. After 20km or so the top green light will have faded to nothing, then the second green light will be full, fading to nothing in another 20km or so. I just went out this evening - only 7km, but power was assisting fine for a lot of...

No.

Thanks. I usually go out for 8 - 10km rides. What I have seen with the display is that the top green light gradually fades and then goes out after 2 journies. Third journey maybe 4th the second one will go out. Have not ridden any significant distance after I have just red. I have noticed a...

Thanks for reply. Yes, the old batteries have been ditched. New ones are 36V, 8.8Ah and 36V, 7.0Ah respectively (gents', ladies'). Both show same symptoms, at any speed. Uphill the motors sometimes groan, and cut out much more. First pic - gents' handlebars, 2nd = ladies'. I weigh 72kg.

I just had an idea. Could I use both Li-ion packs (in parallel) so see if it is indeed the problem that the new battery packs can't give enough umph? Is there any danger in doing this? I would use wire of suitable current-handling ability.

Here are some pics. Maybe someone could identify the various items' suitability. As I said, Li-ion battery packs, correct voltage, will not drive the motors properly (intermittent power). Whether they are too powerful or not powerful enough seems the question, but importantly what can I do...

What I really want to know, is what would you do if you were in my position? The new Li-ion batteries are same voltage. The pics here show the cells I got out of the metal can (I had to slit it open, the batteries / electronics / insulating sheets were tight jammed inside). There were 10 cans...

The mystery for me is that the 'old' lead-acid pack (I stripped it apart) comprised 12 metal-sealed cans plus a load of electronics. If I use 3 12V SLAs, what about electronics? Will I just then have throttle-control? Will the motor be ok with such an arrangement?

Several months ago I was given 2 old electric bikes from a recently-divorced friend who no longer wanted them. They are Zoom Swift140 model, gents' + ladies'. Can find absolutely no info online. Friend thinks they are 10 years old. Both hadn't been used for years and both had totally duff...

Thanks for all your help. I'm now waiting for a new 36V Samsung cells pack. But, because the sender (in Poland) uses GLS Delivery, I might be lucky and get it before Christmas!.

Thank you. I suppose the Philyons are beyond recall? Maybe 6 years since they were last used. Out of the single one is coming 0.3volts.
