This morning near Greenhead.

South Tyne on a cloudy June afternoon near Melkridge and Bardon Mill.

Interesting input. If that is correct, and it is 11KW,, with the 72 volt battery, the thing is about 15 hp which would still be unlikely to reach 73 miles an hour in realistic conditions, but it would get over sixty most likely. It's always a bit surprising how heavily the wind resistance starts...

While I have no sympathy at all for this 'thing' or its owner, there is no way that a motorcycle with a 2000 watt motor would ever get anywhere near 73 miles an hour. The air resistance load comes in massively over about 45 - 50 miles an hour. 2000 watts is about 2.5 horse power, certainly not...

My throttle is still there, but it is locked out in the settings and not accessible from the screen. I would need to connect the ttl/usb lead and undo the adjustment I made. A throttle that is locked out by firmware, is not a throttle.

Thanks for that Nealth. The question I asked has been thoroughly answered. Nothing to worry about. The range seems less than before, but I never used this amount of power before, and the route at the time in question had covered 25 miles and almost 1900 feet of climbing. Of course the range is less.

@guerney I don't think I want to disturb it for a reason like that. Thanks for the idea anyway. It's working and I can ride it 25 miles up steep and lengthy hills before i need to stop pulling 16 amps out of it. If I had continued hammering it, it would soon have hit the 31 volt cut off and...

You know, I could almost swear it is a 6p battery, not 4 or 5. That ought to reduce the sag at high power. EDIT: Yes. Just removed the battery from its holder. Bottom of case is engraved - Sanyo. 13Ahr 10S6P. May 2021. They must be 2200 ma types or near. six 2200 ma runs out about 13.2 A hr...

In that video, Guerney seems to be being pursued by maniacs. Looks like if an accident happened someone might be had up for 'Wanton and Furious Driving'. One of the offences mad cyclists can be put in the dock for. :) https://en.wikipedia.org/wiki/Causing_bodily_harm_by_wanton_or_furious_driving

My settings - copies of the config web pages:

I think it is about 13Ahr. 36 volts. Going by the numbers I see on the display, I see about 550 watts when the voltage is around 39 volts. This comes out at about 14 amps draw on the battery. The controller is currently set to a maximum of 16 amps. I have experimented a bit with the settings...

Thanks for the info and the warning..... But... Why? I'm loving that motor now I have it legal. Cuts off at 15mph, plenty of power to go up hill, and silent as befits my name - Ghostly quiet. Maybe you should have got a Bafang instead of the other one. I can also Ghost pedal and it flies up...

Thanks Matthew. Yes, It had done a fair mileage - over 20, before I noticed the sag, and as soon as I backed off on power demand it perked up no end. I am charging the battery now and will re-test when it is up at 40 volts to see how much sag that level of power demand causes when the battery...

My bafang BBS01 has spent more time in the garage than on the road over the last three years. It has done about 2000 miles and has been kept charged when not in use. Now that I have tinkered with the firmware settings so I can get easy access to higher power levels in my hilly location, I am...

It is incredible what some of the more practised balloon folk can achieve. Dave VE3CKL has had balloons which continued multiple, and I mean many circumnavigations and stayed up over six months, continually transmitting on a twenty minute schedule in daylight with about 15 milliwatts of WSPR...

I have been running a WSPR beacon 24/7 since about 2012. An OFCOM guy came to follow up a spurious interference complaint from a crazy neighbour in about 2013. The neighbour - a nutter - thought that I was responsible for every failure of cheap electronic tat in his house because I had some...

I still think that no one has seriously considered the idea of having a windmill on the front of the bike. I know some airliners have a deployable wind generator for emergency power which emerges from the bodywork and enables some electric power if all else fails. Personally, I would keep it in...

I have a Brompton for carrying in the boot. I am considering a conversion for that bike.
