Schmidt Hub Dynamo System - BikeRadar

It's regarded as the best for good reason. I've had one for the last three years for use on the commuter/utility bike, it has also seen use on winter evening training rides. It has been faultless throughout, and although it adds a good bit of weight, there is no perceivable drag added. Check out the latest generation of LED headlamps such as the B&M IQ range for a fit and forget solution that compares most favourably to the equally (if not more) expensive rechargeable options.

I'd second Graham G's review. I've only had mine for a few months now (but it's older than that, having bought it second-hand), and newly coupled with the outstanding B&M IQ Senso Plus that Graham G mentions, my only regret is that I didn't get one years ago. Reliable, efficient, well-made, always there, paired with LED lights (I'd highly recommend the excellent, fit and forget IQ Senso Plus), it should be the only lighting system you'll need on your tourer/commuter/utility bike. The best accessory I've bought for my bike by a long way.

I've used one of these for about 5 years now coupled to an Inolight 10+, and it's performed flawlessly. The bike lives outside in all weathers, and this has never affected the hub.

If you want powerful lights and you don't have to worry about keeping them charged, running out of power or taking them with you every time you lock up the bike, you will not regret buying the SON and a good LED headlight.

Very expensive, but the last lighting system you'll buy.

Had mine for a couple of years now powering a Schmidt Edelux light, very smooth running, i can't notice the drag. The hub was looking a little second hand, the alloy was slightly tarnished due to being through 2 winters. But still mechanically perfect, until....

I tried to tap out the spindle to accept allen bolts as i didn't fancy getting the wheel nicked when i left the bike in town, anyway, long story short i made a complete hash of it and had to send it back to the factory in Germany for repair. After a 7 week wait i got it back fully repaired, they even polished the alloy back to almost a mirror finish.

Cost? Nothing!! they didn't charge at all. Bloody fantastic!!!

They sound alright but how bright are the lights? I use a trailtech 12 watt HID light (3 times brighter than Halogen) this may appear over kill but I regularly travel 11 miles to the pub and back on completely unlit rural roads, ordinary lights just aren't up to it even at my gentle less than 10 miles an hour average speed. The battery weighs in at 1kg but should give 6 hours light. Any chance anyone tell me what the light output is what voltage and bulb used?

For johnbrand. I just read a review at peterwhite dot com under headlight that reviews quite a few lights and includes photos of their beams. May help in matching lamps to dynamo hubs.

these hubs are superb there are a lot of lights on the market but with varying output i have a 60 lumin busch and muller front light which is great even unlit roads the only down side is they are quit plasticey and broke trying to adjust on the move, the one that looks very bright and bomb proof is the solid light , these have handle bar mounts so can easily be removed and put on other bikes also can be used with a battery so you don't have to have a dynamo on every bike down side all the bits dynamo hub/wheel ,light ,battery and charger all add up but does mean a light for all bike not just the one with the dynamo hub, peter white cycles is worth a look aswell

johnbrand,

Some independent reviews of dynamos and lights here:

The son 28 is a fantastic Hub.

I am using mine to run an B and M IQ fly and may soon swap that for a Cyo with 60 lumens a brighter light due to better heat sinking. currently on my other bike with a dynamo.

If you want the best light it seems Philips has the best beam pattern but you can't get these in oz.

According to B and M website " bumm.de " you cannot use iq fly with a secondary light.

If you really need more light you can pair two iq cyo r headlights there are other options around if you c/o candlepower forums some designs for 3 and more leds using voltage doubling circuitry The son 28 can drive up to 8 or 9 watts of led's but this is a bit techy for me.

The Iq cyo r is not a lot brighter than the iq fly it has a smaller beam pattern less lit in front of bike than the fly They are both very nice lights,and way brighter than my old 12 watt smart halogen system. Also the issue of drag with the Son 28 is not even noticeable when you are riding with the lights off and even when you have the lights on the drag is incredibly low.
