Dynamos – Talk to me…
I know there’s a couple of dynamo enthusiasts on here.
I’ve been thinking it might be nice to have some dynamo driven running lights on my commuter just to be sure that if the battery driven LEDs give up for whatever reason, I’ve still got some sort of active illumination this winter.
I don’t want to spend loads really, and as good as they look having a wheel rebuilt with a Dynamo hub doesn’t appeal on cost grounds, that said “bottle type” roller on the rim/tyre dynamos’s look awful IMO, so I want another way of generating the leccy on the move…
I found a couple of more novel ones when googling last night; one that attached directly to the wheel’s spokes and has a reaction arm on the frame so it’s driven at the hub without significant modification to the wheel being required, and another one that’s attached at on the chainstay and driven by the chain (looked a bit mickey mouse TBH, but the idea has some merit)…
This all got me thinking, I use a flip flop hub on my commuter, could I have something attached to the “spare” NDS hub thread to drive a dynamo? chain/belt/spur/bevel gear driven with the dynamo attached to the Chain or seat stay, neatly tucked out of the way.
Surely someone has done this already? and if not, why not?

Not heard of that. Sounds like Reelight are closer to what you are after, but a “proper” set-up still shits all over them.
I’d spend the £ and see the light, if you spend enough time on your bike in the dark you won’t regret it.
You can get a wheel for £100 retail (or do a rebuild for less), lights for £50 or so,Posted 4 years agocookeaaSubscriber
Oooooh I’d not found reelight before cheers for that; the SL150 and/or SL550 looks like about what I might be after, seems like a better concept than what I was on about perhaps… Or are they really a bit feeble? is that the issue Al?
It was really this effort that got me thinking: SUNUP ECO DS-1R SPOKE DYNAMO
The whole point being, I don’t really want a new wheel, or to rebuild my current one… well not right now anyway, and I kind of figured that seeing as I have what is essentially a spare connection point on the Rear hub, there’s a good opportunity to drive something from it…
How much more juice do you get out of a proper hub dynamo anyway?Posted 4 years ago
not sure on any of the bigger ones cookea – jaynes is an SL100 compact – works well for what it is – a back up flashing light that never needs turning on/off
Al – mrmo – anyone else that has half an idea…. what lighting would you recomend to go with that wheel ? – i want a revo but just cant bring my self to spend on a revo…… – when i have a perfectly good working but old and worthless ( because folks would rather by those nice reliable exploding china lights every year) maxx DPosted 4 years ago
I haven’t used it,
But would have a look at the new B&M cyo premium.Posted 4 years agocynic-alMember
I dunno about the Reelights, I suspoect they are more “be seen” than “see”. My set-up is good enough for me for night solo road rides, I’d never go back.
trail rat – I went for B&M, using the strip-light at the back (mine brightens under braking) and the £80 60-lux front. No regrets.Posted 4 years agoMartin BMember
