In mathematics and science it's pretty much ideal. The problem is that being based on an arbitrary standard it simply doesn't suit many ordinary day to day uses. Judging or quoting a person's height in centimetres is very inferior to the single numbers of feet and inches, the expression a...

Thanks Martin, but I like state of the art when I have a use for it. My computer I use much more for other interests than this forum and it's as good as it gets for general use, Intel I7 3.6 gb processor, all solid state hard drives and a high speed broadband connection that's rarely as low as...

Thanks for the explanation, and EddiePJ has illustrated the accuracy. Handy if one is changing territory regularly, but on my routes I'm happy with the once-only cheap and precise method I've used. As previously said, I'd have a smartphone if I had the regular use for one and any phone signal...

Really! How? What is it measuring? .

This Dutch Sparta/Koga motor was first seen as a single speed in the Sparta Ion, using a freewheel, but quickly changed to derailleur after a frosty reception in Export markets. The revised model was named Sparta Ion M-gear. Therefore I'm pretty sure it will be a multi-sprocket freewheel, but...

Can't let you get away with that. :D Who ever rides or drives up steeper than 1 in 1, apart from a few extreme off-road maniacs just before disaster strikes! As for such as phone apps and other handlebar methods, the readouts can easily be up to 20% out. Probably good enough for many of...

The kilos and litres examples illustrate what I meant about only needing familiarity to accept percentages for hills. I fully agree about kilometres though, and that is just one of the questionable suitabilities of parts of the metric system for common use. Hence my expression in the reply to...

I'm sure there's nothing to worry about. The police like clear cut law to prosecute and avoid like the plague all the vague areas which might involve them in difficulties. A good example is the law against pavement cycling which is full of possible pitfalls. As a result the "offence" is...

Just as much with angles and slopes though as a quick web search showed on this link Of course if the metric system had been even more daft with 1000 degrees in a circle, we could have used degrees meaningfully to express hill steepness! .

Yes, very true, but as I observed earlier, percentages do enable a single number rather than the cumbersome 1 in X expression. However, there's no law on what we use in such as this website for example, so each to their own. Personally I've found percentages just a matter of getting accustomed...

True, but it at least is a means of useful comparison. I think using decimal points with degrees makes for even more confusion, since degrees are normally divided by minutes and seconds, both units of 60. Once someone knows that a percentage is instantly convertible to a 1 in X figure by...

You are completely missing the point, no-one routinely climbs a 20 degree slope. The whole range of what we climb covers very few degrees, making degrees as a measure useless. Tell me, how many degrees are 6% and 8%, typical of the slopes we need to know? Whether someone can draw a slope is...

Yes, direct conversion. .

That's far too coarse. The range of hills we climb, especially on roads, cover very few degrees at the lower end of the scale. There's a real difference in climbing a 5% and a 7 or 8% which can't be adequately expressed on a degree scale. That's why we have percentages and the related 1 in X...

The Council is then. Getting permission from them could be difficult due to bureaucracy and possible health and safety implications. They might just say no to close the matter conveniently. Avoiding asking them just means getting your neighbours to accept it, but even if they do the council...

Check with the freeholders (landowners/landlord) first to get their permission since they might object. If they are happy it may make it easier to persuade your neighbours to accept it. .

No they aren't gone. All the other consumer methods I've come across all too easily fail any accuracy tests, I just tried the Woosh one on a correctly measured hill and found it reading 3.3 low, seriously wrong on an actual 14%. I then tried three other local hills of various gradients and all...

I'm afraid I can't help with the stripping, but the motor is a Sparta one. That direct drive motor is very different from the internally geared ones that most feature in online videos etc. I think the torque sensing is in the rear wheel and there's also some software linking incorporated since...

Recent reliability has been a factor for some, they seem to have deteriorated in that respect. The biggest factor for most users and probably the trade is the battery prices. The top end 36 volt 9.6 Ah battery for example I last saw at £1050, a truly shocking price for that capacity. I don't...

One of Halford's trucks bearing their large "WE FIT" slogan has got stuck under a low bridge at Beckenham. Seems they don't fit that well:
