As I think you know Paul, I ride legal e-bikes and don't support illegal usage. However, I disagree with this notion that what is happening will bring more law into force. First, the matter is too insignificant to attract official attention where it could matter. Second, the EU impediment to...

They can't be complicit with any liability in something that is legal. There is no law preventing the sale of e-bikes or dongles that are not legal to use in any public area. Liability exists only with usage, not with supply or support for supply. For example, take the far bigger problem that...

The high bypass proposal originally came from GE, but since the only potential customer for the 747 at the time was Pan-Am who used Pratt & Whitney, Boeing and Pan-Am jointly decided that P & W should develop the engine for the 747. Unfortunately history gets rewritten by the victors, so the...

I don't disagree, and I'd add the surrounding wall of air also increases the thrust efficiency of the central jet. In this there's an important relatonship to the lower throughput speed of the high bypass engine that Tillson refers to. .

Indeed, the S class pedelec class was designed expressly for road use only and in the countries where it's permitted, they are usually banned from cyclepaths. Having 45 kph assistance is of no practical use in off-road conditions anyway. .

I know, appreciate and broadly agree with this Tillson, but wanted to avoid such length as your post demonstrates necessary. I'd hoped that it would be taken as read that the volume and speed of throughput would be too limited on a bike powered system to make any worthwhile difference to the...

It's the same for most of us, we just don't see the illegal bikes. That's because there are so few of them, spread out across the whole country they disappear. This forum gives a false impression of there being lots, but in reality we never have very many active members and only a minority of...

Welcome back Paul, don't stress too much about Cyclecharge immediately, all things in good time. We haven't heard directly from Linda for a long time, but I assume she has been trying to get her business back on the rails after her illness. .

It will never make any difference. It's EU law and that isn't going to change because of a minor degree of misbehaviour in one member country, especially when that country plays such a tiny part in the European pedelec world. Anyway, the DfT isn't stupid, they know that additional regulation...

That's better, much larger thrust area than a small ducted fan. It would leave a trail of blood in city streets though! .

The video illustrates the only time this concept is any use, for speed on the flat. Any gradient or headwind would bring it to a standstill. The problem is the small area of thrust at the nozzle, the area of air it's pressing against being too small to realise useful power against any real...

Looks good, I think you'll probably just about get away with that tall battery, just so long as you don't do any stunt jumping! :) .

Yes, just as Norway etc have to, including also the EU pedelec regulations. .

With each post you are sounding more and more like Enoch Powell, and that is apposite for he represents the past. Yes, the world has changed and I accept that you and the other Brexiters dislike it, but we in the London that you now dislike are the future. The vast majority of our near nine...

You've no cause to feel dishonest when virtually all the legal e-bikes are under declared. They are commonly capable of much more than 250 watts continuous and often more than the 350 rating of your motor. You're just following common practice. Just don't say that to a police officer! .

We've often been the odd one out with handedness on two wheelers, brake levers being but one example. Many years ago our motorcycles had right hand foot gear change, one up for bottom gear and the rest downwards, and left hand rear footbrake. But from when the Japanese bikes arrived we had to...

Many years ago and long before the EU, I had a job which entailed a long period of working in France on a development while being employed and fully paid in the UK. My UK employer also gave me a very generous expenses allowance. However, the French associate company insisted I had to be fully...

In some models of the Giant e-bikes this Sanyo motor regenerated so had no freewheel. If your wheel rotates freely in one direction but is notchy in the other direction, it's a freewheeled non-regenerating version. Notchy both ways it's a regen version. At a guess the thick black wire at the...

A bit behind the times in the sticks it seems. Here in your capital city of London, well under half of the population are white British born, so we are all minorities. And as for being born in Europe, we've always been, including you and me, since Britain has always been a part of Europe. .

Those arguments are simplistic though. Of course the EU will trade with anyone if the price is right or the import is not readily available from elsewhere. The UK doesn't have much to offer that fits either of these criteria. The EU can manage very nicely without its tiny percentage of...
