USB Dynamo Powered Charging Device + Fitting

USB Dynamo Powered Charging Device + Fitting


We have a few options here for a dynamo powered USB charging device. The Sinewave Reactor, the Sinewave Revolution, the VeloCharger and also the Pedalcell. Please also see the Sinewave Beacon in headlights for a dynamo front light with integrated USB charger.


The Pedalcell does not require a dynamo hub.


N.B. these are only available to purchase when buying a Stanforth bike

  • Starting with the Sinewave Reactor:

    The more we use Sinewave products the more we are impressed. Sinewave seem to have the edge over other brands we have tried in their level of waterproofing. Although the top cap USB port is exposed it is designed to be waterproof, for this reason it is our preferred top cap style USB charger.

    The Sinewave Reactor takes the performance of the Revolution dynamo-powered USB charger (detailled below) 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.  The cap is only 9.8mm tall and available in silver, black, red and blue.  This is only available to buy if your Stanforth bike will have an ahead stem (non carbon fork)


    Sinewave Cycles Revolution USB Dynamo Powered Charging Device

    The Sinewave Cycles Revolution is a bicycle dynamo powered USB charger. It converts electricity generated by hub and bottle dynamos to USB output. The Revolution allows users to charge USB-powered devices whilst they ride.


    This does not sit in the steerer tube like the Plug III. The Revolution can either be cable ties to the frame, bars or stem or sit in a frame or bar bag.

    The Revolution is made in the USA

    The VeloCharger USB charging system was designed in the UK and is produced in Portugal. 

    The VeloCharger is designed to work with a Hub Dynamo and takes the raw AC voltage from the dynamo and convert to a stable 5 volt DC supply - suitable for charging a mobile phone or other USB device. There is an integral USB socket to accept a charging cable.

    The VeloCharger has been in production since 2015 and has proved itself to be one of the most powerful and reliable chargers available. It is easy to fit, and provides the ideal solution for keeping your devices charged when on long rides or touring.

    As we haven’t tested this wired with a dynamo headlight, we would recommend the velocharger only if a dynamo headlight isn’t going to be installed.


    PedalCell - Bicycle USB Charger

    If you don’t have a dynamo hub but want to charge your devices or lights on the go, then the PedalCell fulfils that need.

    The American PedalCell rim dynamo is a super-efficient dynamo with USB charger that can be mounted on any Stanforth Bike. It is particularly ideal if you don’t want a hub dynamo on your bike, or would like extra charging capabilities as well as your dynamo hub.

    The biggest advantage of the PedalCell is that it delivers more current than a hub dynamo with a USB charger - 15-20 watt output and it can be decoupled when not in-use.

    Smart Power Hub:

    • Patented CadenceX Technology

    • 1X prioritised safety USB-C (600mA, 5V)

    • 1X high-powered device USB-C (2.4A, 5V)

    Drag Adaptive Based on Speed and Device Power Needs

    Weight 1 lb (490g)

    Enclosure Weather-resistant

    Consumables Rubber O-Ring Replacement every ~2-3K miles
