Not if the motor stops while power is applied - say in a fault condition. It will draw very high current. Hence warning about the controller mosfets.

If you have a Bafang programming serial cable, you can turn off that 'run on'. It is very easy once you get cable to do the job. GENERAL INSTRUCTIONS Load this web page for the BBSxxx series, and do it all with that: https://devnotes.kymatica.com/BafangWebConfig/BafangWebCfg.html The...

That really makes it clear and I'm just surprised that I never came across this concept before now. Here is another example made in metal by another young experimenter and this one shows exactly how the idea works in a proper robust engineering material and in practical real life applications...

That's a very detailed and thorough explanation. Thanks for taking the time to explain it. I'll have another look at the graphic now, and see what I can make of it with your description in mind. Still wondering what material the flexible gear is made of, to last a sensible life in this...

The resolution is easily good enough to read number plates at 10 meters. Battery duration might be the weak point. For £20 the quality is amazing. I would be interested in hearing how you get on with the INNOVV H5 4K Helmet Camera when it comes. Battery life on that seems amazing.

What's up with him? Nutter?

Interesting. Picked up on two interesting innovations - Strain Wave Gearing High frequency sampling of crank speed I don't really understand that gearing idea in detail. I looked at the wikipedia diagram, and see how the graphic seems to operate, but don't really see how it turns...

No, I doubt banging through the gears without backing off the motor would do it any good at all. You were not supposed to even pedal when you made it change. I can't think how the little gear change chain would get twisted up, except by being twisted up as you tightened the adjustment, but you...

It would be interesting to see how that SRF3 hub copes with the mid drive power. I've been inside one of my SRF3 hubs that had done 4000 miles plus and it was pretty much unworn. They are quite sturdy inside, so if you are not using high levels of assistance from the motor, they might last ok.

Heroic riding! Maybe you are a young fellow. There was a time when I thought a hundred mile trip on my unassisted Dawes Galaxy tourer was pretty ordinary.... Not anymore. I wonder how you regulate the output of the panels to charge the bike. How long has your tour been going on? I got the...

Has your old outfit worn out or something? I'm just curious why you want another set if you already have one. How have you found the reliability of the BBS01B? I keep reading of reports from people who don't like mid drives, of their 'unreliability.' Mine has never given a problem, other than...

I wouldn't want my more delicate regions anywhere near those raptor beaks. A few weeks back, I returned home to hear strange noises coming from my wood burner stove. Opened the door and there was a jackdaw sitting in there, so I put my hand in to get him out and set him free. Little barsteward...

Nice. That would fill a rainy afternoon. :)

I always held you in high esteeeem my precious..... (said in Gollum voice. Do you have shiny thingssssss.... :)

I bought a sticker which I have not yet applied to the downtube. I did this for the convenience of any policeman who was interested. The motor is stamped 250, but not 250 watts. It is a BSB001 Bafang. It is set up with the max speed (25km hr) written into the firmware settings and not the LCD...

It's pi ssing down with rain here. Wanted something to think about.

No expert, but i think charging in strings of ten with 42v charger might not be good. That is IF you were using LiFePo4 as suggested here. Ten series Lithium Iron Phos would terminate charge at 36.5v. Not 42v. Maybe i introduced confusion by suggesting a different battery type. You can buy a...

Yes, i know what you mean about sometimes having few options. That's an interesting outfit you have there. How much charge do you get from that panel in weather like this?

Cells are 32mm x 70mm and weigh 140 gm each. For approx 38v nominal in 12s 2p config, you'd need 24, so if two rows of 12 you'd have a rectangle 12x3.2cm approx 39cm by 7cm high and 7 cm wide. Obviously, the packaging of the cells and accommodation of the BMS and connectors and padding is not...

To be honest, I wouldn't ride on roads like that one. It's only a matter of time before some selfish idiot does you harm.
