    I would not call it detuned. I asked Bafang to do me a 48V 16A 250W BBS01. I call it BBS01ET for extra torque because it's the BBS01 but with a souped up controller. The BBS02 is supplied with 48V 20A controller. I suspect that Bafang simply programmed the controller to suit me. I don't want to...

    A 500W BBS02 has 48V 20A controller but not road legal. you can buy a BBS01ET, 48V 15A 250W kit from me but it's not as suitable for cargo bikes as a rear hub DWG22C or SWX02. The controller on the DWG22C/SWX02 is 48V 17A against the BBS01ET's 48V 15A. The BBS01ET is more suitable for mountain...

    both have the same torque rating. Both are good for cargo bikes up to about 250kgs total weight. The Bafang SWX02 has thread for freewheels, the DWG22C has freehub body for cassettes. The Bafang is drilled for 13 gauge spokes and slightly smaller, so a bit easier to lace. We have both in stock.

    with a rear hub kit, you can still ride after you break your chain ;)

    Denwyn bought secondhand one of my CD bikes in 2013. Back then, there was no gear sensor. He lives in Somerset where hills are everywhere. He sold it in 2016 and bought a Wisper. I started to fit gear sensor to the Woosh Krieger in 2016 after he sold his.

    your bike has torque sensor and weighs what? 21-22kgs and you weigh? 60kgs? shifting gears on AXS takes a tenth of a second. It's not the same when you have a 200kg-250kg cargo bike on a cadence sensored crank drive shifting an Acera derailleur. The gearshift sensor on the BBBSes turns off the...

    all motors have tradeoffs. Crank drives put a lot of tension on the chain, making gear shifting very difficult. If you fit a shift sensor, it loses power mid shift so going uphill can be a struggle. For cargo bikes, the DWG22C on a 24" rear hub is a very good choice. It will give you excellent...

    rear disk brakes: The DWG22C needs 180mm rotor. How big is your rotor? It's a skilled job but not difficult. You can learn to lace a wheel with Youtube video in about 2 hours. Getting an LBS to do that for you will probably cost about £70 + the cost of the spokes.

    Hi Karl, If you go for a rear hub motor, you will need a high torque motor like my 48V DWG22C. You will have to relace it to a 36H 24" rim to suit your cargo bike. The hub motor's flanges are drilled for 12 gauge spokes. 14 gauge spokes are thinner and more flexible so usually preferred for...

    Two boys die in "ebike" accident: Cardiff riot broke out after 'police prevented parents seeing fatal crash victims', close relative says

    Microsoft only agrees to buy electricity from Helion. It's an advertisement coup for Helion's investors such as Sam Altman who runs OpenAI. If Helion manages to produce electricity by 2028, they both win. If not, they have nothing to lose. The issue is Helion's approach. It's unlikely they'll...

    I am not saying that technical solutions for fusion are readily solved but they are well within our understanding and reach. I suspect that the reason fusion is still a long way from in use is because energy companies are all powerful and controlling to the extend that they dictate government...

    I don't think saneagle supports Tate's view litterally. He tends to use the third person in his narrative so not to mix his true thoughts with Tate's.

    The Times article started with this 'AI systems are powerful enough to kill many humans'. Hello? where have you been in the last decade or two? Machine learning is the previous name for AI. Just look at our various weapon systems and drones, which ones don't have machine learning components in...

    he is a libertarian. I reckon he does not mind winning or losing an argument. He's just taken up the defense of the weak, in this case, Andrew Tate against the BBC interviewer. Tate isn't liked by you and me, but he's free to spread his version of blokeism or worse. How Tate is making a living...

    there is usually more water in the rocks than on the surface, even on earth. Anyway, we can make water with basic chemistry. The main thing is we need to develop small fusion reactors with a diameter of 2M or less that we can carry on boats, planes and spaceships.

    We don't need to colonise Mars for living space, at least for the short term. The idea is to advance our understanding and science. AI is going to put a lot of humans out of work, the pressure is then on to reduce the over population and the need to grow food will be vastly reduced. We'll stop...
