Re: Police advice to wear cycle helmets

Not sure emergency services staff have the best perspective on this, because they only see the injured / dead. So if helmet compulsion were introduced and resulted in a considerable decrease in cycling participation (Australia?) the measure would be perceived as effective in the emergency room (they...

Re: Every breath we take: the lifelong impact of air pollution

Assuming there is such a thing as "pollution capacity", should it not be reserved for those activities which are most difficult to mitigate? Arguably we shouldn't pollute at all, but I don't think anyone believes that's achievable. That probably does mean road transport, as there is a wide...

Re: Every breath we take: the lifelong impact of air pollution

We (as a society) need to address all causes of air pollution rather than just consider what affects us. I've regularly posted arguing against car/diesel pollution even though it hardly affects me. I am beginning to get the impression people only want laws addressing issues that affect them persona...

Re: Every breath we take: the lifelong impact of air pollution

Petrol does emit no2 but a fraction of that of diesel engines, and it's no2 that most of the current concern is over. And yes, retrofitting can help to a degree but likely will not be sufficient, some kind of clean air charge to drive the offending vehicles in the affected areas is likely to be the...

Re: Every breath we take: the lifelong impact of air pollution

I thought the concern was that focus on one type of vehicle fuel would distract attention from other pollution sources. For cyclists, though it probably is diesel vehicles which are the main concern. We tend to end up riding just behind the tailpipe. If the close pass doesn't get you... Diesel fumes...

Re: Every breath we take: the lifelong impact of air pollution

Seems to me that what we have is a conflict between two different ideas, or levels, of environmentalism. For those whose primary concern is global climate (and therefore overall carbon emissions), diesel is still superior to petrol as a vehicle fuel. Diesel engines (particularly without emission con...

Re: MTB for £200 or less

Go back, fish your old bike out of the ditch and fix it? It probably won't cost £200 and you will learn a lot that's useful. Then the next time you need a bike you will be able to buy used with confidence, knowing you can repair anything that goes wrong. Bikes, in my opinion anyway, shouldn't be dis...

Re: Every breath we take: the lifelong impact of air pollution

Coming back to Southampton, since it's the one of the five cities I'm familiar with. It seems to me that the city has a particular problem and also an opportunity which is likely to be missed. Unlike London and possibly other major cities, Southampton is very short on public transport options. There...

Re: Bikejor: The people who race their bikes with dogs

Sadly illegal on UK roads, where a dog may not draw a carriage on the highway.

Re: Front light positioning

Does that mean "you must have a front light in that area" or "you must not have a front light outside that area"? Logically it's the first with regard to width (you may have a light on the nearside as long as you also have one on the offside) and the second with regard to height ...

Re: Every breath we take: the lifelong impact of air pollution

There's a suggestion that Southampton's problem is not road traffic at all, but marine. Apparently the cruise liners are obliged to run their engines while in port to maintain electrical power. Certainly it's interesting that neighboring and more congested Portsmouth is not on the poor air quality l...

Re: Spider alert

I picked one up in the living room some time back, to transport it outside. As I cupped it in my hand, it bit me. It actually hurt! I suppose you may have encountered the Hobo Spider of ill repute, rare in Britain and rarely found indoors here. But after a bit of googling, it seems that the much co...

Re: recommendation for a low cost E-bike

Legal top speed "back in the day" was 12mph. Perhaps with the heavy, low output lead acid batteries it couldn't do more than that. Pretty sure any upgrade which allows assist above 15.5mph will make it illegal, though it's unlikely that the authorities would take any notice unless you have...

Re: recommendation for a low cost E-bike

How does the performance compare with other ebikes? I remember pre-2015 ebikes as being distinctly unimpressive, but it may well be that the battery upgrade brings it up to post-2015 performance (2015 being the date of the rule change). I suppose the other question is "Is it legal?" I don'...
