If you’re particularly conscious about saving the environment (and we all should be, really, shouldn’t we?) then, of course, regular cycling is a great start as an alternative to driving.
But if you really want to go that extra mile – pardon the pun – then why not fit your bike with self-powered, dynamo bike generator lights?
What Are Dynamo Bike Lights?
A dynamo is an energy-generating hub that’s built into a bike’s front wheel, primarily to power lights.
Bicycle Lighting System Powered by Wheels
Early dynamos were tyre-driven, having first become popular between the First and Second World War, when English bike component manufacturer Sturmey Archer introduced the ‘Dynohub’, which moved the generator inside the hub of the front wheel.

Initially quite clunky designs, they’ve come on leaps and bounds since then, yet although they’re more commonplace in cycling hotbeds like Germany and the Netherlands, they remain quite unfashionable elsewhere, in places like North America, in particular.
How Does Bicycle Dynamo Lighting Work?
With dynamo lighting, there’s no need to fidget around trying to flick your bike light while cycling at the same time. They run on pure pedal power.
It’s quite simple to explain, really. Using the rotation of the bicycle wheel to generate electricity, the dynamo can then produce an electric current which is then delivered to the lights. The faster you cycle, the more power generated, and so the brighter the light.
How to Fit a Bicycle Dynamo?
Installing a dynamo hub on to your bike is a pretty straightforward process. You just attach it to your front tyre, lining it up in such a way that it runs on the white part of the tyre, before fastening on tightly with a screwdriver. This YouTube video should explain it all to you in less than a minute:
Pros and Cons of Bike Dynamo Lights
PROS OF DYNAMO LIGHTING
- Never needs re-charging
- Safe, powerful and extremely visible form of lighting, using durable LEDs
- Environmentally friendly and recyclable
- Far more difficult to steal than standard bike lights
- After initial investment, you may find they’re more cost-effective (no purchasing new lights, batteries, no need to pay fines if you forget your lights one night)
CONS OF DYNAMO LIGHTING
- Friction dynamos (or ‘direct contact dynamos’) can make bikes a little harder to ride because they slow them down when they come into contact with the tyre
- Friction dynamos also cause increased wear and tear on the tyre, and may slip in wet conditions
- Maintenance can be a problem – you may find strips of metal stuck in your bike or worse, you may sever the electrical circuit if assembled incorrectly
