Make sure you don't end up with too long a reach. You may need to fit a very short stump neck stem or even a zero reach stem to bring the hands back to a sensible distance. It's not unknown to need to fit a reversed stem such that the bar clamp is behind the steerer.

Here is my take on bullbars. Looks complicated but is that way to to get a low enough bar height on a Dahon and to reduce reach. The gear change arrangement works extremely well.

I found the best way to get rid of it was to carefully tease it out of the hedge/tree or whatever (best done early for obvious reasons) and train it to grow around a piece of bamboo untill there is sufficient leaf growth and then use a systemic weedkiller on it. If done this way good wetting is poss...

Suggest you read this forum thread.

Should be what you want.

Looking back it appears that I have not posted my take on using flar bar shifters on drops (OK, these are not drops but the principle would work). http://i34.photobucket.com/albums/d116/wilesfamily/IMG00019.jpg I used these for a 20ml commute every working day for over two years and absolutely loved...

Where did you get yours? I bought it online either through their shop or via their Ebay shop (which no longer exists) - I can't remember which. This was a few years ago now. http://www.sunupeco.com/shop/!/EcoDyn-bicycle-dynamo/p/62827570/category%3D12799534 This is an Ebay USA seller (Intelligent D...

Agreed, but on most bikes it would be fitted to the additional weight in negligable.

A review in English here:

Not a hub dynamo, but the SunUp dynamo fits on Shimano rear cassette hubs. I have had one for a number of years and it has been totally reliable and is of an efficiency equal to a SON. In it smoother in operation than a SON and to be honest you really don't know it is there. http://www.sunupeco.com/...

I have a right hand crank arm machined to allow clearance for a modern derailleur for sale if anyone wants it. http://i34.photobucket.com/albums/d116/wilesfamily/DSC00740_zpsq89qdlkf.jpg http://i34.photobucket.com/albums/d116/wilesfamily/DSC00664_zpsnf2zglvc.jpg Reply or PM if interested. Russell

I note SA managed to squeeze 30 magnets into their ill-fated XAG prototype: A 3 phase hub and rectifier has already been rejected by the forum as too complicated.... :) I have been using a 3 phase generator on one of my bikes for quite a few years now. Very smooth with no flicker and completely rel...

23mm Wheels come highly recommended, although a little out of your area.

Um, this is a bit embarrassing! I received the initial complaint by text but the important bit of information, that the dynamo was not in use, was missing. It turned out that the non drive side axle nut was not tight causing flex and associated brake rub. Sack the mechanic!! All is now well and drag...

These were bought when quality hub dynamos were in their infancy and have to date provided good power with reasonably low drag (and no slippage). She currently uses a high power LED headlight so a decent dynamo would be required to replace. It is for commuting but battery lights require to be remove...

Didn't apply lube to the cog wheels as there a toothed rubber belts driving things around. There is a bearing carrier of sorts between the metal drive ring and the plastic body. Like this, but ours is cleaner! http://blog.lolyco.com/sean/wp-content/uploads/2013/12/spokedynamoinside.jpeg
