the good thing about crank motors being attached to a pentagon like Bosch bikes is the torsion generated by motor and pedalling is much better spread compared to hub motors.

it was done at the time when aluminium alloys were not as rigid as now. You could make lightweight frame with a trapezoid. The bigger the triangle / trapezoid the stiffer the frame.

No, you don't have to explain these points. However, you wrote this about me: I am not sticking to any of my predictions but I do try to stick to evidence and I read a lot on Covid biochemistry to get my facts as well up to date as possible. So when you talk about me denying evidence, I have...

let's start again. Your post includes this link: https://www.cityam.com/london-now-counts-just-24-new-coronavirus-cases-per-day/ the article did not include any link to the source of the study substantiating the '24-new-coronavirus-cases-per-day' in the title. Feel free to point me to the...

Being a merchant, I am pretty neutral on the subject TS/CS and crank/hub. I do sell more CS and hub so it's natural that I repeat some of their advantages. I'll post some pictures of the Brompton fitted with the TS kit tomorrow. You can buy it from next month.

where are the ONS numbers regarding London? The number of new confirmed cases (2500 a day) is an average over the last few days from the NHS website as reported to WHO. Check out how many are still admitted to London hospitals requiring COVID treatment every day. If only 24 are new confirmed...

Brompton sells through distribution channels so the retail price includes margin for the shops. Torque sensor gives you a different riding experience, that's all. My TS kit is also available for the Brompton from next week. It's also very easy to fit.

nothing to do with denying any evidence. In the absence of specific evidence regarding the number of new confirmed cases in London, we use the national figure * percentage of population living in London = 2500 * 9M/65M = 346 new cases a day. A very long way from 24.

No doubt that London is hardest hit by CV, but how many people have caught it? The formulas are simple: S: percentage of susceptible population + I : percentage of immune population = 1 Re = R0*S R0 was 2.5, determined times and times again in Wuhan and other very large cities. For Re = 0.4...

same Hoisin sauce served with Peking roast duck.

I would suggest XF07 front hub or XF08C rear hub kits. https://wooshbikes.co.uk/cart/#/product/uid-192-xf07kit-13ah/xf07-front-hub-kit-with-13ah-battery https://wooshbikes.co.uk/cart/#/product/uid-121-xf08c-13ah/xf08c-rear-hub-kit-with-13ah-battery

I agree mostly to this view. With the cadence sensing system, you still have to pedal, but you can decide how much you want to pedal, choose your own cadence and in most circumstances, don't need to change gear. You use the electronics to adjust the motor's output to suit you. The torque sensing...

I find that difficult to believe when the official national new daily cases still running at 2000-3000 a day.

If I were Johnson, I'd let him go on account of the herd immunity strategy. It is clear now that herd immunity is not the correct strategy.

I could sell the kit minus the battery may be from September for £299.

Cummings is irresponsible and can be dangerous if Johnson takes his advice uncritically. The country is better off with him gone and I wouldn't want to see him in the HoL.

Hi Julie, I am looking at some small form factor battery cases. The earliest is in October.

Cummings is probably the architect of the 'herd immunity' strategy which caused additional deaths and delay in provisioning the NHS with much needed equipment. Any reason to sack him is OK to me.

13AH is roughly 470WH. As there is no throttle, you'll get good 40 miles out of a full charge. It's enough for a full day riding and the battery is locked, you can leave the bike parked at a public place. That's why I started the project with the small frog kit.

the controller is especially thin and lightweight (85mm×45mm×22mm ), installed in a mobile phone case, mounted onto the handlebars.
