Dynamo power systems

How do dynamo systems work?

A dynamo system is made up of a dynamo hub, which acts as your onboard, muscle-powered generator, and connected devices, such as lights and chargers, that put that electricity to good use.

What is Dynamo efficiency?

Dynamo efficiency refers to the amount of power available relative to the amount of drag slowing you down. There is simply no free ride when it comes to harvesting pedal power – you always have to work a bit for it – but a higher efficiency means that more of your pedal power can go directly to charging.

Which dynamo charging system is best?

The PedalCell offers significantly more power than any other USB charging system, it’s 42-70% more power than the best hub dynamo charging setup tested (Schmidt SON28 dynamo hub & Forumslader V5 charger). The PedalCell is especially impressive at low speeds where it’s already delivering 2.5-watts* before 9KPH.

Which dynamo battery should I use?

Special dynamo cache batteries such as the Tout Terrain Power Pack and Voltaic Systems V-25/50 allow low charging currents and pass-through charging, but regular USB power banks (especially cheap, “dumb” ones) often do the job just fine; you’ll need to do your own experimenting.

Should you use a dynamo system?

It’s true, a dynamo system removes a massive amount of stress especially in a racing situation. But instead of thinking about battery capacity you’re now thinking about the terrain ahead and whether it’ll be fast enough to generate power, when to charge what, and which mode to put your light in.

What is a rim Dynamo?

This three-phase rim dynamo is a charging-only kit with everything you need to start a bicycle power station! The “Smart Power Hub” simply attaches to your stem, and it has two USB-C charging ports – a “safety” port with 3-watts maximum power and a “high-power” port with more than 10-watts of available power.
