Dynamo hubs & USB chargers

Lights and hubs and USB charging… Oh my!

We use hub dynamos systems all the time and on all kinds of bikes.

There are too many good lights out there for us to list on our little website but we mostly use Busch+Müller as they have proven themselves well made and reliable. For off-road use such as 24-hour mountain bike racing the USE Revo is a neat solution that fastens to the handlebars and throws out 800 lumens, more than enough to see where you’re going. We’ve used these very successfully whilst doing events like the Bearbones 200.

Get in touch or pop in to see what we’ve got and discuss your options.


Invariably a lot of our builds use an SP dynamo hub as it’s a good value product available in a range of colours and options – including a 15mm bolt thru version and now a 150mm fatbike / Jones compatible unit.

Son (Schmidt’s Original Nabendynamo) units are available in many different options and finishes, with a five year warranty, though you are unlikely to need it.

We also use Shimano dynamo hubs, which we’d normally recommend for city bikes.

Lights that charge!

Sinewave Beacon Headlight Version 2


Buy Here

The Sinewave Cycles Beacon Headlight is a 750 Lumen Dynamo powered front light with integrated USB charger.

Features include:


    • Flicker-free light down to 3-4 MPH.


    • Charge your phone, GPS, or any other USB device directly from the Beacon; no need for a separate charger.


    • An external, off-the-shelf USB battery pack can be connected to maintain bright, flicker-free light even when stopped or riding slowly.  Any available dynamo power replaces battery power until reaching a speed when all power is provided by the dynamo and the battery is no longer used.

    750 LUMENS

    • Lots of light, suitable for any style of riding.


    • Ideal choice for off-road riding.


    • Dynamo power is optimized at low-to-medium speeds, reaching 100 lumens at 5 MPH, 375 lumens at 8 MPH, 600 lumens at 10 MPH, and 750 lumens at 13 MPH.


    • A reduced brightness mode for situations where full brightness is not needed, and for easy power sharing between the light and charger.


    • A supercapacitor, charged while riding, provides about 5 minutes of standlight when stopped.  The standlight can be turned off with the toggle switch.


    • A blinking mode is available when using external battery power.


  •   The 10mm mounting tab is compatible with mounting hardware from B&M, Supernova, Schmidt, etc.  You’ll need a bracket to attach to your bike, we have various bar and fork crown mounted options.


And so much more! Read the full specification on the Sinewave Cycles website. 



  • Designed to be used in any conditions.  Multiple seals protect against water ingress, electronics are potted in epoxy, and all connectors are gold plated and designed for resistance to the elements.


  • All Sinewave products are made in the USA.  The Beacon is the only commercially available dynamo light made in the USA.


  • 3 years


  • The Beacon comes with a USB-to-DC cable.
  • A mount is not included – there are many options available for different mounting locations.  Contact us if you need advice about mounting options.

We can post these out, just give us a call and we can arrange next day delivery if you order before Noon.

( Tuesday, Wednesday & Thursday only )

The Sinewave Reactor £234 takes the performance of our Revolution dynamo-powered USB charger and shrinks it into a package that fits above the star-fangled nut in a threadless steerer tube, with a pass through for the 6mm bolt.  The only visible part is a custom CNC-milled stem cap holding the USB connector. This needs a steel steerer and will not fit modern carbon forks, if you’re not sure give us a call.
