Bought a geared front hub motor from China and got it spinning using this controller. As the no load speed increases (I haven't put it on a rim yet) there is a mechanical knocking noise coming from it (at lower RPMs it turns smoothly). The vendor claims I'm using the wrong controller. Has...

If you could live life backwards: You start out dead and get that out of the way. Then you wake up in an old age home feeling better every day. Then you get kicked out for being too healthy. Enjoy your retirement and collect your pension. Then when you start work, you get a gold watch on your...

Not wishing to detract from the heroic efforts of the workers at the plant, but it seems more like a farce to me. Why did they have the backup generators in a place where they could be flooded? If there was more openness then surely someone could have pointed out the risk in that? How come...

'We will be able to live to 1,000' By Dr Aubrey de Grey

That's exactly the fatalistic feudal attitude which the Enlightenment fought to overcome by placing man at the centre of the world. Worryingly it's this misanthropic environmentalist/climate alarmist fear which the political elite are promoting as a way of securing a last vestige of authority.

Direct potential new members to a short essay on ebike/elecrtical basics. Then set a short comprehension test. Maybe 3 questions.

Think the Earth is finite? Think again The more the merrier as far as I'm concerned. ps. I drive an ev because I'd prefer to live in a city with cleaner air where we don't have to wipe up black dust in our houses.

This thread reminds me of a Brendan Behan quote above the bar in a local pub - "I have never seen a situation so dismal that a policeman couldn't make it worse."

There was a video posted recently of a guy giving a lecture on lithium ion cell chemistry, can't find it atm. IIRC he said that 50degC was the temp at which the organic solvent in the cells starts to degrade. My headways get up to 35degC after a half hour run at 25degC ambient and I haven't...

I'm not you sure you want to be sitting on top of 144 - 180V DC with the possibility of melting snow in the equation. This is one application where I'd want to keep the system voltage at ~50V max and gear to that.

There may be some useful info in this thread about a similar toothless planetary gear hub motor called a TARN.

EDIT: Refined proposal: 1. Rename 'The Cesspool' to 'Everything Else'. 2. Move 'General Discussion' into this section. 3. Rename 'Other Toxic Discussions' to 'Potentially Offensive Topics' and keep the caveat 'WARNING: This area may contain offensive posts or controversial topics.' 4. Make...

I voted other. The problem is partly one of structure. Placing 'General Discussion' near the top of the forum list gives it too much prominence. I enjoy reading off topic (ie. non EV) stuff and agree that it helps build the community. I can fully understand Bob taking offence to his thread...

There was a young woman from Bude, Who went for a swim in the lake, When a man in a punt, Put his pole in her ear, And said: "Oi, you can't swim 'ere, it's private!"
