Busch & Muller headlamps have the advantage over others that they do not dazzle oncoming drivers or pedestrians, because their beam of light is cut off from the top in a special way. In addition, B&M has rear lights with a brake light function, for example (B&M Toplight Line Brake + / 80mm) - a nice thing if you drive a lot after dark in traffic. Greetings from Poland! 👍
You shouldn't charge straight from the dyno hub, it'll stuff the battery of your device. I always use a power bank in between my dyno and my devices. You pug your dyno into your power bank, and then your device into the power bank, so during the day your power bank in charging and at night you can charge your device (you can charge your device at the same time while charging the power bank). This way you always get the right amps for charging your device. And your device battery will last longer too.
Hub Dynamo's are a far cry from the Bottle Dynamo's i used as a kid. Looking into adding one to each of my bikes. Thanks for the video. I love your presentation and accent. Thanks again.
Exposure are well worth the money. After going through various brands I got sick of replacing them as I try to ride all weather. Nothing lasted longer than 6 months. My LBS recommended an Exposure TraceR rear light and it has been absolutely bomb proof. Best light I've owned by far. 2 years and no issues. I'll be honest, not a fan of dynamo wheels though. I like to keep things nice and light regardless of the distance. My Wahoo lasts 12 hours+, my lights last for the amount of hours I need, as does my phone. I just pick the kit carefully so I don't need a dynamo. Each to their own though.
Thanks for the walk through.
Nice presentation.
I also have the SP dynamo. I bought mine after noticing that a lot of the top riders in the Indipac used the SP. No need to route both sets of cables down the fork to the connector if only one device can operate at any time. Just allow for a small junction/connector near your bars. Regards cost, I paid about £65 for the hub from Spa Cycles, used an existing rim and bought spokes to suit. I built the wheel myself and paid Lbs £10 for final truing. Total cost about £85 to £90. Light is twin led I built myself so low cost and long throw.
Ahh thanks will look into that :)
I will do some digging. There has to be a way to add a junction box and selector switch so you can switch between the light and USB. Great video!!
Igaro Products and klite both make a switch and extension cable for the Exposure Revo to switch between light and USB charger. Hope that helps.
Ahh thanks so much Paul!! :)
Hi, got theie Strava light. Awesome.
BUT Exposue are 'vague' to say at best with regards dynamo charging anything other than their Revo light.
I have their 8.7 amp support cells to back up my Strada.
Exposure tell me their dynamo cannot charge it!
Not impressed.
You have to do your own research.
Cool, that's nice riding right there!
I'm looking to get a Stator hub for my bike : Salsa Fargo
I had a dynamo back in 1967 in USA. It would be fork mounted and have a drive wheel that ran against the sidewall. The faster you went the brighter the light. Whole setup was affordable to a 10 year old. It was extra fun.
Off cuts of inner tube make good straps for securing the dynamo cables to the fork. Simply feed the cable through then slide them up the fork! My home built dyno wheel was around £150 all in. It is a Shimano xt dynohub, so probably heavier than a fancier SP hub. I tend to just leave my dyno wheel on all the time rather than swapping it over. Think of it as extra training!
Helicopter tape is even better. No ugly zip ties or electricians tape going around the frame. Transparent and totally unobtrusive.
Very illuminating upload
Brilliant! Thank you,
I didn't know Exposure did dynamo lights.
Expensive, But Very good quality and British made.
It also has a stand light that lasts for 1hr (after 15mins riding) long enough to set up camp or fix a puncture at the road side.
Most others only last 4-10mins, even the German ones.
And they do Hub dynamos from £100.
Great video, but it's VERY expensive.
BTW you can use Relight as back up lights ....it works on a dynamo/ magnet principle but costs around £20..
Also, I'm surprised that no one has invented an alternator for a bicycle yet.
Practically speaking, a dynamo hub is an alternator, also called a synchronous generator, with permanent magnets rotating with the wheel around a static coil where an alternative current is induced. Or am I mistaken ? Or did you mean something else ?
@@groovy_bear Actually a dynamo generates DC and an alternator generates AC.. Doesn't really matter whether the coil spins round the magnet or vice versa (although the latter may be easier to make), it depends on how the coil is connected to the output (slip ring commutator for AC and split ring commutator for DC)..check this video out for a better explanation: ua-cam.com/video/AxuMPuIgjSU/v-deo.html. I don't know whether any manufacturer uses any kind of brushless technology in their dynamos or alternators yet. Dynamos are not the most efficient generators really. 😉
@@fredflintstone4558 Thanks for the link, quite interesting and well explained indeed.
However I just want to point out that, from what I understand, it actually matters whether the coil rotates around the magnet or vice-versa, at least from a practical standpoint. Bicycle generators (whether they are bottle "dynamos" or "dynamo" hubs) are not really dynamos (hence the quotes) but *magnetos*, because they all use a permanent magnet rotating around a static coil and they lack the need for a commutator. Bicycle dynamo is an abusive term.
en.wikipedia.org/wiki/Magneto
Magnetos are classified as alternators although they're not the most common type. Again, the key thing here is they do not have commutators, that's why they only produce alternative current. But they need quite a bit of electronics to cope with the voltage increasing with rotational speed.
Hope that's clear and I'm not mistaken. My engineering knowledge on that topic is a bit fuzzy as this is not my specialty...
Great info. The steep price is what is holding me back. For now I'll have to continue using my chunky battery packs for my longer rides.
The value outweighs the price if you are out a long time. Other lights/dynamos are available.
@@markrushton1516 at what distance/time and event frequency do you think it makes it worth it?
@@TheMichaelGrace When you are going into longer dark/low light/rain conditions esp in Winter. A decent battery light will work fine but you are relying on the battery being charged fully and in good condition
@@TheMichaelGrace Most of the battery packs have between 700-1000 charge cycles lifespan.
Basically 2-3 years of everyday use.
Then you buy new battery packs £££! And 18650 battery packs aren't cheap, they also don't like extremes of temperature, too hot kills them, too cold and they don't last any length of run time + it kills them.
Don't get them wet or short circuit them or they're liable to ignite.
Most battery packs are water resistant NOT waterproof.
Don't buy any rated at over 3200ma as that's the max capacity that exists & prepare to pay through the nose for them.
3000ma cost £31.99 + delivery by courier (can't post them in UK)
+ £16 for 2 cases to make 2 battery packs = £32 for three yrs max.
Then add in the cost of the lights.
Don't forget that you need road lights which have a shaped beam Not mountain bike/off-road ones. They are illegal and you can be prosecuted, the only time they are allowed is if they flash (not strobe).
Then add the cost of the REAR light + batteries.
Don't forget that it costs to charge the battery packs & you have to remember to do this BEFORE you ride.
So you need a CHARGER or TWO = more ££'s
======================================================================================
Yes the dynamo lights from Exposure are quite expensive BUT
you can get some really good front ones for around the £50-£100 mark, rear's for £7-£20.
I got the AXA luxx70 (front) £56 and AXA riff steady (rear) £11 (both have stand-lights).
A shimano dynamo hub built into a wheel can be had for around the same price, less than £100.
You can buy the hub dynamos for £20 on their own and build it into your own wheel.
AND
Once fitted you have lights....Permanently without messing around.
Plus they're fitted to the bike and harder to steal/less desirable as they're harder to sell on.
So to answer your question: Cost effective Immediately!
Hi Katie I like dynamo setups my light as a usb out put port and O am happy with it, just a thought that any electrician should be able to wire in a two way switch rather than having to keep pulling wires out of the back of your light. I prefer dynamos they tick a lot of boxes for me.
When you think about it; a hub dynamo is just about the greenest way to power items on your bike. You're taking available motion and using it to make electric power. Not a new idea. But, thanks to smartphones and GPS and yes, lights it's slowly becoming a little more common in the USA.
You have just "enlightened" me to the world of dynamo hubs. Sorry, I'll get my coat.
hey im a helliwell too !
I have several Exposure Max D lights but not dynamo lights. They are simply fantastic, turning night into day. No one pulls out on me and car drivers who don't dip their main beams do so immediately when I aim it straight at them. The only thing I have found which is bad with Exposure lights is that the plastic wires are crap in cold weather. They crack. I bought one of their rear Red Eye lights and by end of the first winter the black lead for it had started to become brittle and crack. Where it entered the light it failed. Also I bought two of their large capacity oval batteries which give the Max D lights a really long burn time on full beam, but same thing happened with the cables for these. They started to become brittle and crack so much so that the cables for both have failed. So one rear light and two batteries from them were a total waste of money as I only got one season's use out of them. Exposure did not want to know when I complained. Now for rear lights I have gone back to CatEye the TDLR 600 which is reliable work horse, bright and has been totally reliable over 4-5 years and still going strong. Plus it is a hell of a lot cheaper than corresponding Exposure rear lights. Their front lights such as the Max D are good, but their rear lights avoid.
I bought the Sinewave usb charger but it came without a plug to connect it. Normal? Many thanks
I've been running a Son hub and Exposure Revo light/tail light for about a year now so was interesting to see what you thought of it compared to the other light. It's on my commuter/audax bike and I leave it on all the time mainly because in the year it's been on not one car has pulled out on me. I think there's something about the strength and position (same as yours) of the light that makes people pause and then they seem to wait. So personally I'd leave it on even through the summer. Hub and light weren't cheap options but I've had no worry about charging light batteries for however long the ride for the last year - so lack of battery anxiety easily balances the initial cost.
I never really went down the route of USB charging, instead I bought a Garmin Etrex 30 which runs for days on a couple of AA batteries. I do believe there was a connector though which you could plug in instead of the rear light - so using the light's output socket. Might get around to it though if I ever do any multi-day bike packing.
I got a solar battery back my my last tour but don’t think it worked cause it never seemed to charge even though it was during last years heatwave in August and was in direct sunlight. Got a different type of one now so going to try that one in Wales this month, see if it’s any better. If not then will convert to a hub. At least it will work and can still carry a lighter battery back for back up
You are twisted each wire of dynamo light and sinewave together and put it back to Dynamo Hub Wire Connector. Am I right? Can you turn on dynamo light and charge your cellphone at the same time?
You can just put a switch on one of the cables. Not hard at all. Just make sure to waterproof the connections.
Excellent video! Good ideas to try. I have a "chunkeey" spare light as well...lol
pause at 1:11, it looks that your trailing spokes and leading spokes are laced for the disc brake wheel, rather than rim brake.
Cheers will looking into that.
And there was me thinking it was a gizmo that rubbed against the tyre and generated power that way😉. Great vid as always😊
Thanks Katie, useful video.
Very helpful. Thank you.
Hi Katie, so did you run the Exposure cable and the Sinewave cable both into the plug on the dynamo? Eg twist the Exposure and Sinewave positives together and the negatives together separately in each side of the SP connector?
costly but what price to see and be seen ! well explained cheers
Not that expensive when you consider that a cars HID bulb can cost upwards of £40 just for the BULB!
And Wheelchairs are bloody expensive!
Sweet set up. Thanks
Great video, so helpful. I have just bought a dynamo wheel set and the exposure light set. However, neither came with the plug to connect the wires to the dynamo. Did yours come with the lights or the hub? Any idea where I can get one? Thanks
In theory the output to your rear light should be able to also be a charger port. Exposure make a series of usb cables. So in daytime you could run your front light and power the usb. Or if there is a suitable connector the input to your light may also be available to charge. Ask Exposure but the first suggestion may be the best. Unfortunately a dynamo can only produce a finite amount of power.
yacf.co.uk/forum/index.php?topic=67905.0 reply #8
😁 Cheers Katie
I believe, the SP (8-series?) is laced to a Mavic Open Pro UST?
The Exposure Revo is, indeed, ridiculously expensive. And has been due for a revamp since 10+ years. A lovely lamp, otherwise. Just terrible at charging.
I like the idea of the Dynamo hub and light, but its expensive and all those wires around the handle bars...I don't like that...I am going to look at a solar set up and see how it compares
While the SP rolls really well (the speed penalty is roughly about a kilometre an hour, possibly less), it doesn't generate nearly as much power as some of the competition. The very expensive SON, while it weighs about the same and rolls roughly as well, generates quite a bit more energy and would, depending on the charger tethered, charge a USB device and power the lights at once. Some newer Shimano dynamos provide a lot more power, too - but are much uglier, significantly heavier and roll much worse.
I had a SON 28 and a SON Delux. Neither one flickered on slow climbs, while this one does.
By the way, yours is not the PD-8X (that's the Centrelock version) - it must be the PD-8 (I guess), one of the non-disc ones.
If there was a 10000 MHA powerbank in between the hub n lights then in day you powerbank charges and then later the lights run off the powerbank..
Very informative I will take a look on wiggle
The light on Wiggle is reduced at the min I think...
You want owww much said in my best Yorkshire accent lol. Intresting to see the set up but bloody hell not cheap. 👍🏻🚴🏻
Thanks this video cleared a lot of doubts i had. If i want to run just the sinawave without the lights, i just run the cables down and connect them straight into the socket with a connector, right?
Yep
Hi Katie, nice to see your lighting setup. Do you also use reflectors when riding in the dark?
I wear this: www.provizsports.com/en-gb/switch-gilet
Every overnight ride I do this comes out.
very interesting...but too much wiring... i prefer the extra battery charge that i Always carry with me..cheers from Montréal !
What size of powerbank do you recommend to charge devices from the Sinewave?
Can you by the hub already built into a rim or did you get those separate and build yourself?
Hunt wheels do them all built together. I did mine separately
i went for a knog PWR mountain, massive overkill for road riding but i ride a gravel bike and like to ride off road at night and it can be absolute pitch darkness
i use two of them so i have 4000 lumens total, been looking into getting a dynamo but not sure if my lights will work with one
Illegal for road use!
I use powerbanks myself on multi day rides, and while I do not use them myself, I understand the Igaro D1 or the B&M USB-Werk will power your devices independently of the light, and also while using the light.
I've used B&M lights for nearly a decade now, with various hub dynamos and also with the Velogical dynamo, both with and without the B&M e-werk. All work great, although the Velogical is a bit draggy and noisy (albeit extremely light). As the lady pointed Out B&M lights allow to turn on and of on the go, without having to dismount... Good video!
Oi tudo bem, abraços aqui do Brasil.
Did i miss something ?, what happens when your going up hill slowly ?
You run out of juice!... Literally!
Where's your basket?
Hi Katie, just wondering when u did the 312 did u do it through a company or can i register for it myself and book flights and hotels myself, any help or advice is greatly appreciated thanks johnie
Nope it's probably cheaper to book your own flights and accommodation (I like Air BnB as it's super cheap) and then book directly with Mallorca 312.
Thanks for replying and info, I'm heading over next week to do the tourmalet u ever done it
Is the brand of the light Dynamo or just the hub? Don't see Dynamo lights like your on the web for sale.
Brian K Kinney exposure revo. Looks like it’s by dynamo or just designed to work with their hubs
@@MuddySump Thanks
@@MuddySump I caught it watching it a second time and she say's the manufacturer of the light.
Klite makes a micro switch...
Do the hubs spin as free as a normal hub?.....
Yep
@@KatieKookaburra Thx Katie😀...
No, they don't. The electromagnets definitely affect the axle. But it depends on how you spin it. If you were to move the wheel back and forth on the bike, you probably couldn't tell the difference.
However, try to turn the bare axle? Difficult. My wife couldn't turn it, whereas a similar quality hub axle will turn effortlessly.
But it's a small amount of resistance to have 24/7 light that never dies. For many, that's worth the tiny resistance penalty.
1 А?) really?)
Wow not cheap then Katie ...
It's not but some people spend £1000s on lightweight wheels - I like mine with a dynamo haha.
Katie Kookaburra wow .. yours are cheap then lol
at the end of my vids i make evier for facebook are sometimes youtube i say adios cos i got it off alex marzbar vlogs haha
Google sent me here and my dyno set-up will be virtually the same as yours but one thing I'm struggling with is the mount for the light on the Go-Pro mount. Is it one of these as the image used isn't obvious exposurelights.com/products/bike/brackets-and-mounts/light-mount-for-action-camera-bracket
Yes think that's it, but just to be sure drop Exposure an email, they are an awesome company with great customer service :)
@@KatieKookaburra Been running this set-up since April and added the rear light a month later. Still struggling with the standlight thing after getting home and seeing the faint glow from the front light 2 hours later.
Here's a Radical thought, why don't you get something like a 300000mAh 20 LED Solar Power Bank Portable Dual USB Battery Charger which you can strap to you handlebars, then it charges using daylight!!
Daylight or sunlight? We don't get enough in the UK to power it.
@@KatieKookaburra .
There's a popular myth that solar panels need sunshine, but all they really need is Daylight to work.
Obviously they produce more energy if there's sunshine.
From the research I've done, if every house in the UK had 1 solar panel , we'd only need 25% of the power stations that we have. ...
Not really well explained.
what a mess with all the cables.rather run out of juice then ride with Bangkok style cable spaghetti
That is where we differ. You get caught out in the dark then - then you won’t be able to see any cables 🤣🤣🤣
@@KatieKookaburra Great response :-)
