These aren't accurate figures, but most hub dynamos output 3W / 0.5A 6V AC maximum. When converting it to 5V DC, the maximum current will be again roughly 0.5A (assuming no conversion losses, which there are).
With the E-Werk voltage set to 12V DC, the output current will drop by a corresponding amount, ie to less than 0.2A. The E-Werk circuit doesn't somehow create charging current out of thin air, and can only work with what it's provided with from the dynamo.



Looking at http://www.forumslader.de/typo3temp/pics/590d4cd9bb.png

...my understanding is that at 20km/h the 12V and 5V settings of the E-Werk cross over at 3W, but at higher speeds, both can give more power, with the 12V setting giving over 5W at 32km/h. That would equate to 0.42A. This is because the E-Werk is presenting a load that is different from that required to clamp the dynamo at 6V.

Generally speaking, it is safer to keep up with the flow of traffic as usually, (among other reasons that I can't think of right now coz it's midnight and I'm falling asleep but which are covered in Richard Ballantines bike book) following drivers won't feel the need to overtake and a faster moving bike is usually more stable than a slower one.
Depending on the town, size of road and time of day, it's perfectly easy to keep up with and even exceed the traffic.
I'd agree that speed and the ability to stop in a safe manner are to be judged carefully, but it's difficult to know the limits of a new-ish bike until those limits have been exceeded.

I'd bet the differences in road deaths in different European nations are largely due to factors other than speed limits.

Actually if you break it down by road type then speed does feature stronlgy.

The UK performs comparitavely well in terms of road safety for car users. Since a large proportion of car mileage is on motorways then this is strongly influenced by our reletavely low motorway speed limits, making our motorways some of the safest in the Worrld.

The UK performs extremely poorly with respect to the safety of vulnerable road users - who are to be found on the non-motorway roads. Here our reletavely high speed limits lead these roads to be relatively dangerous by European standards.

And most of those vulnerable road user deaths are in built up areas where Britain has slightly lower speed limits than most European countries. 43% of pedestrians killed are over the alcohol limit for driving with 34% at least double the limit. I wonder how that compares with other nations. Only 13% for cyclists though.
Anyhow I'd like to see comparative statistics if you have any. For example are vulnerable road users safer in Albania or Serbia with their 50mph limit than here with a 60 limit.

Germany loves rules and regulations....

Of interest to you may be this: http://spacycles.co.uk/products.php?plid=m1b0s21p3106 - £950 for a spa cycles 3k carbon framed bike with full shimano 105 (and a triple!) is a bargain. It doesn't say in the description whether the frame takes guards, but i would guess it does because the specced brakes are deep drop.

JUst noticed Ribble Sportive 365 Campagnolo http://www.ribblecycles.co.uk/sed/road-%20...%20=conf_SERW can take 25mm ryres and mudguards so suitable all year round ?
Don't know it's weight. I was thinking of a Specialized Roubaix, but is this better ? Realise it costs more than the Winter Audax at £1000.

Re: Ribble Winter Audax bike

Anything comparable to Ribble winter audax but can take 25mm with guards? Prefer to be in similarly priced.

That's a fair comment. While I'm not sure about the 'largely', it's certain that reduce speed limits only help because they are enforced. And other factors will contribute as well. How much each factor influences it, is impossible for me to say.

Adds to the adventure then! Get a Basha tarp and find some invulnerable spaces to bed down.

When I was doing it in NZ (one of the easiest to I imagine) it was cold, so I was desperate for shelter (before upgrading my gear) going a bit far by bunking down in derelict barns, not so derelict barns, unused holiday home sheds and even a section of an assault course of a school. With the barns, a kiwi told me they would have gone crazy if they found me, yet if I just asked they'd say "no worries". Always best to get locals advice..

At the risk of starting another helmet debate I really don't think you should leave it there. You won't know what impact or stresses it may suffer, especially if the damage is not visible.

My old one was a decent enough frame, but very tight with 25mm tyres and guards.

Nor is 20mph achievable on a lot of off-road tracks even if there was nobody else on the track, given the surfaces that are often used -clay and packed gravel, for example.
We don't need to be on the road. We just need to be on a decent cycleway that isn't shared with walkers or built from porridge. You know, like our cousins across the water in the other Holland have.

The UK has a fatality rate of 4.3 per billion km. The only countries with lower rates are Denmark (3.4), Iceland (3., Ireland (3.4), Sweden (3.7), Norway (3.3),

Their motorway speed limits are - Denmark 110-130kph, Iceland 90kph, Ireland 120kph, Sweden 110-120kph, Norway 100kph. So 3 of the 5 countries with better safety records have higher motorway speed limits than the UK (70mph is 112kph).

I have highlited a small word that you seem to have missed in the post you are replying to. Particularly as this is a cycle forum, where conditions on motorways are not particularly relevant to our safety.

Thanks for that Pete. I had indeed missed it A dancing bear moment.

Two questions...
What has been done with the rear derailleur? It looks like there's a bottle or something in front of it.


I have broken linked the rear derailleur to the chain stayes through zip ties and then I have covered it with a plastic bottle stuffed with boubble wrap.

Is there a spacer or false axle in the forks to protect them?

I have used this thing:
