Make “Oh, I forgot to charge it” the last time in your life
For anyone who rides a bike every day, nothing is more disappointing than that moment.
Daily commutes, trips to the shops, or rides on rainy days.
Precisely because it's something you use every day, you want it to work stress-free, efficiently, and tough in any weather.
I think a tool being truly “good” isn't just about high specs; it's about making the user's life a little richer and a little freer.

What I want to introduce today is a German treasure that promises to free you from that kind of “hassle”: the pinnacle of dynamo hubs, SON NABENDYNAMO.
Trust Named After the “Sun,” Born in Germany
I can say with confidence that adding a dynamo hub and lights is a choice that reliably raises the quality of life for anyone who rides every day.
“Make a bicycle's power supply something you can trust more.”

SON was born from that philosophy.
The “SON” in the brand name comes from the German Sonne (sun), and “Naben” means hub.
Symbolizing the efficient, steady use of natural energy, the brand develops and manufactures every product entirely in-house.
High-precision bearings, excellent waterproofing, and durability that lets you use them maintenance-free for years.
The reason touring riders and commuters around the world rate them so highly is their overwhelming reliability: they just don't quit.
Rolling So Smoothly You Forget It's Even Turning

SON dynamo hubs are known for extremely smooth rotation and low drag. Designed so that even while generating power they don't spoil the ride, they are a true fusion of functional beauty and practicality. More than just a part, they're something worth using for a long, long time.
I'd like to introduce two bikes belonging to people who have discovered this “comfort so smooth you forget it's turning.”
Two Owners Who've Discovered the Joy of Never Charging
First up, this RETROTEC.

A bike built for enjoying everything from cruising on pavement to exploring unpaved roads at a relaxed pace.
It originally had a regular hub, but as the owner started using it for the daily commute too, “charging stress” became an issue.



It would be a shame to have the fun of such a beautiful handmade bike spoiled by a dead light battery. With the switch to a dynamo, this bike has evolved into “the perfect companion you can take anywhere, anytime.”
The other bike is this BIKE FRIDAY / Diamond Lama.

The owner already knew how convenient a dynamo is from another bike, and went for it convinced that “this bike, which I hop on casually so often, is exactly the one that needs a charge-free dynamo.”
It's used every day, of course, but also for rides on trips, whether bagged up on the train or carried on the car.
Precisely because you never know when or where you'll need a light, a dynamo setup really proves its worth.


SON's light rolling doesn't spoil the zippy ride that small-wheeled bikes are known for, making it a perfect match for a BIKE FRIDAY darting all over town.
You don't even feel like you're “running a light” anymore; you simply get safety and convenience, naturally.
A Light That Never Goes Out, for the Adventure of Everyday Life
Your light is always ready to switch on, with zero hassle of charging.
This “given” is actually hugely valuable in a life with bikes.
Some of you may not have realized just how convenient it is yet.

It may feel like a bit of a splurge as an initial investment, but once you have it, there's no more dependable tool.
Turn the companion you take out of the garage every day into a tougher, freer bike.
Experience the “days without worrying about battery life” that a SON dynamo brings, in your own everyday life.
If you're even a little curious, feel free to ask us.

Circles Tailored also carries dynamo hubs, dynamo lights, rear lights, and other related accessories.
This was just a quick introduction, but next time I'll go into more detail on each product.
