Or you could just let the pilot increase the pedal assist level when he noticed there was a hill because his legs were having to work harder. Why make riding a bike more complicated and unreliable? I don't understand. The joy of cycling is that it is such a natural extension of your own body...

I don't know if you are aware of the tiny (1.8gm) programmable, balloon transmitters made by Hans Summers and sold for about £50. They have gps onboard, transmit their position, altitude, battery voltage and the temperature, using the weak signal protocol WSPR on a variety of frequencies, and...

Yes Peter, you were right in that post you linked to. :) I expect all that power change stuff will be abandoned with the coming election. Pity - if what was being talked about was passed, I could plug in my throttle again - not that I need it. Others might benefit from that though. To be fair...

Update on Programming the Bafang BBS01: I went into the settings again and set Keep Current to 100%. I also set speed at all PAS speed levels to 100% of the maximum allowed from the screen (which is 15 miles an hour). The PAS levels are set as percentages of the maximum current now. I...

YES! This is the issue. It is tempting to buy REALLY cheap and think you got a bargain. Around 1975, I bought a UK made electric drill. It cost £40 then. In modern value taking account of inflation that drill cost me £309 (courtesy Bank of England inflation calculator. You can go into any...

Thanks for that tip. I wonder why it was set at 20? Pretty weird. I'm chuffed that with Guerney's help I got into the controller. What exactly is Keep Current?

Success! With https://devnotes.kymatica.com/BafangWebConfig/BafangWebCfg.html Yes - it read my old parameters and I saved them to disk for future recovery if needed. Then I tried editing and saving. I found the 'Write All' at the top of the web page was refused consistently, but the write...

@ Guerney Just messing about with that web page configurator at https://devnotes.kymatica.com/BafangWebConfig/BafangWebCfg.html This recognises my cable when I plug it in. When not plugged in, USB does not appear in the interfaces listed, but once plugged in, USB appears. It also says it has...

I checked out the links you sent. The settings in chrome are set to allow usb access from websites. The bike is in my Gf's garage a couple of miles away in the next village, so I can't try to connect with the web page Bafang Web Config right now. I will go over there on a motorbike later and...

Thanks. I thought of that but the software for android does not have any way to put the user in charge of the com ports. There is no reference to com ports on the app. Pity. It is likely that this is the issue. I could scrounge a windows laptop and download software and drivers. I have heard...

This is free energy once you build the plant. Ouarzazate Solar Power Station https://en.wikipedia.org/wiki/Ouarzazate_Solar_Power_Station

Those model aircraft chaps should utilise that idea. They could fly those electric planes forever by doing that.

Small radio beacons can be lashed up quite easily. I did some of this in the 1980s. You do need a bit of radio skill to DF the balloon when it comes down. We also made timers which fired a small pyrotechnic charge to separate the electronics package from the balloon at a predetermined time.

Just alter the seat post with a large spike powered by a spring which when connected to an armed system will fire the spike up through the saddle into the ar se of the scum who stole it. This should be fine as long as you keep your wits about you and don't absent mindedly forget to disarm the...

When my throttle was connected to my BBS01 250 watt average power crank motor, at PAS 9, when operated only by pedals and the motor, the power won't go beyond 250 watt input power. When the throttle was used, the power was around 600 watts. Part of this is firmware configuration which can be...

EDIT: This complaint of mine is solved now. Just needed different software. When you do get the stuff together, I hope it works better than mine. I bought a lead on ebay - looks ok with a clear shrink wrap over the circuitry that does the USB to ttl conversion, but the chrome book and the...

Yes, I've seen them, and the ones where a spark plug and some wires can power a light bulb. I can't imagine why anyone bothers with paying electricity bills or even worse, shelling out for solar panels. People have actually sent me links to these videos asking how it works...... Unbelievable.

This concept reminds me of a 'brilliant' idea I had when I was about twelve. We had been looking at electric motors and dynamos in a science lesson at school, and I was thinking about the way a dynamo is just like a simple direct current motor while I was bored to death on my paper round...

Unless it was weeping a lot of oil, I would just wipe it and ride on. One of my motorbikes has passed four MOTs with a leaking front fork. I just make sure that before the test, I clean it up and as I arrive at the test centre, I give it a shifty last wipe. The tester passes it without...

One of the best things about a bicycle is the ability to freewheel for long distances without losing speed on the slightest inclines. Regenerative braking would sacrifice all that for a negligible input of energy put back into the battery. Problem is that the efficiency of the generation would...
