Compared to ICE, we are still in the early days of battery technology. The bad smell of burning lithium batteries comes from the chlorine and or fluoride and or boron released from decomposition of their electrolyte. Soon, we'll use solid state battery which won't have electrolyte so when a...

the problem is the anti-vax arguments seed reasonable doubt. If you are pro-vax, even have a good, solid, well above average grounding in scientific methods, which many MPs don't, you will have a very difficult job to unravel which bits in the anti vax arguments are reasonable and which are...

If somebody has been vaccinated and died after contracting covid, how do you work out what killed him?

I think it's the weight that breaks the jaws of the fork, not the torque.

The vast majority, about 80%, have been vaccinated, so 80% of 65 millions = 52 millions. This group has 5 deaths per 100,000 per month, total 520 * 5 = 2600. 20% are unvaccinated, 65 millions * 20% = 13 millions. This group has 24 deaths per 100,000 per month, total 130 * 24 = 3120 deaths per...

I had AZ, Pfizer, Moderna and a French one that I forgot the name. What are my chances?

Hub motors (the Santana 3) beat crank drive motors on user serviceability and price, and no need to worry about gear shift. The CD got replaced by the Rambla which was a brilliant bike. However, bafang charge a lot for their motors. The Ananda motor is much more affordable.

Until now, the bbs01b is too expensive for what it is, there is also the issue that many customers need a gear sensor and also can't replace the controller in them. Now, the ananda motor has fixed all the issues above. Reliability has vastly improved, no higher support cost than hub bikes. Out...

I prefer crank drive's weight distribution nearer to the centre of gravity, making the bike feels a lot lighter than a similar bike with hub drive. Also, I never need a gear shift sensor riding around Southend.

His rim needs replacing, the spokes are stainless so easy to re-use. Just undo the nipples and remount as they are onto the new rims. May be worth buying new nipples but there is no need to buy a new set of spokes. I would use sellotape to hold the old spokes as they are, saving a bit of time...

I think your torque sensor is a very good idea. Can the electronics be entirely built into the motor lid? If that can be done, sell it to the aftermarket.

How is it going with your torque sensor inside the wheel? Any idea when I can buy a sample?

that's a good idea.

how about torque sensor + throttle for those steep hills?

The difference in cost between a hub kit and a crank drive kit is getting smaller, in some cases, to be less than £50. When you consider the greater flexibility of torque delivery of crank drives, the better centre of gravity and the time saving on installation, the £50 difference is well...

That happens often. You have to get them to confirm that you want double wall, 18mm wide, 36 holes, 349. Otherwise, they don't know exactly what you need. 16in for them is 305 rims, 22mm wide.

Yes, it should be OK. Spokes: you can reuse the old spokes. If you need a few more, ask Andy.

Brompton tyres are 37-349. You need a 36H-349 rim. I sold some spare rims in the last couple of years because nobody has them, now I am left with motors without rims. I am reordering them now.

I am moving toward selling parts, commencing with motors and batteries. For small parts, there is the long queue at the post office. I go there at 3pm. If I am lucky, the machines are accessible. If not, I have to queue for 30-40 minutes with people who need a driver licence or passport. Then...

Thank you for your understanding. Although the cartons don't need to have made in xxxx to comply when sold within the EU, if the bike is exported to the UK, the cartons must be conform to UKCA and marking rules on cartons, and carry a clear indication of country of origin. Cartons without...
