yes. All geared hubs and bottom bracket motors have inbuilt clutch. Your main issue is the trade off between weight and power. Don't worry too much about the 250W label. It's for flat road at 15mph. The real power at the rear wheel is a lot more than what the label says. For good handling, you...

It's very good so far. Let's just wait until you have got a multimeter.

a geared hub is like a direct drive + a reduction gearbox. The Q128 that vfr told you about has a 10.5 to 1 reduction gearbox, that is the torque of the wheel is 10 times stronger with the gearbox than without. It's excellent for climbing...

show us a picture of your arduino as it is connected to the PC and the throttle at the moment. Check with a multitester that the voltage at the A1 (throttle signal pin) changes as expected when you push on the throttle.

it's the ratio deaths per new cases that you want to watch. At the moment, it's roughly 1 death/30-40 cases. As the vaccine should stop 9/10 deaths, that ratio should drop dramatically. I expect to see 1 death per 300 new cases by June.

perhaps a little exaggerated. In the next year or two, we'll see effective treatment against particular variants.

true, it's just one measure. One TV doctor puts it, 'the vaccine moves the curve to the left' meaning the vaccine lessens the severity of the disease in a person. How much to the left depends on the concentration of antibodies, how much the original viral load is going to be neutralised or how...

nobody disputes the benefit of spreading the stock of vaccine to more people. However, studies show that those who had the second jab have up to 4 times more antibodies than those with single jab. If you have 30 millions doses (roughly what we would have until end of April), would you use them...

@vfr400 - you remember the WSB story? I've just read that Fidelity sold all their 9.3 millions but 87 GME shares at near peak. I do feel sorry for those redditors who still hold.

it is a balanced and political judgement taking into account availability and cost. The AZ vaccine is the only running candidate for COVAX program. WHO can't afford to use any other vaccine. Also, despite numerous reports confirming that prime boot regimen is much better than prime only regimen...

after you can control the frequency of the LED blinks (you want about 0-18 blinks/sec), next step is to write the code to mirror A2-A3 to output the same on A4-A5. When that's done, you should be able to connect the yellow and green wires to the arduino.

no, it's just one added precautionary step which I borrow from vfr's earlier post #105. The extra initial step lets you write the code and test it while the bike still fully working. we still stick to the original plan. To recap: Arduino Pin Controller Sensor Throttle GND black black...

because it isn't true.

the researchers chose hemp for source of carbon but could have chosen cheaper toilet tissue instead. https://pubs.acs.org/doi/abs/10.1021/nn400731g https://ndownloader.figstatic.com/files/4042141

someone is under the influence.

The throttle has 3 wires. Where did you connect them to? I would suggest you solder the throttle input, 5V, VIN and GND wires to the board. Remove D4 and D7 and their counterparts (torque and cadence wires) - join them as they were before you unplug the connectors. The bike should work like...

what do you connect the 5V and VIN pins to?

You can fit a small frog battery either to the seat tube or like this: https://wooshbikes.co.uk/?batteries#smallfrog

the Aikema 85SX on my Faro is very quiet too. It's a rear hub, most of the time, I don't notice it. https://wooshbikes.co.uk/2019/faro/Faro2.jpg

I don't believe that. Where would the missing white lymphocyte cells go hiding?
