When you’re buying a bike for your child, you’re not just choosing colours and wheel size—you’re choosing components that impact comfort, safety, and how fast your child grows into (and out of) riding.
One of those under-the-radar choices is the type of headset and stem: the part that connects the handlebars to the fork and front wheel. At base bikes, we use threadless headsets, just like you’d find on high-performance adult bikes. Here’s why that matters.
What’s the Difference?
There are two main styles of headsets:
-
Quill stem + threaded headset (older style): handlebar stem slides inside the fork and is held by one bolt.
-
Threadless stem + threadless headset (modern style): the stem clamps onto the outside of the fork and stacks with spacers.
Why Threadless Is Better for Kids
1. Safer and Stronger
Threadless headsets clamp tightly and don’t rely on friction inside the fork tube. This means:
-
Less flex during steering
-
Better control at speed
-
Less risk of loosening over time
This matters when your child is riding faster, turning tighter, or tackling hills and bumps.
2. Lighter and Simpler
Quill stems tend to be heavier and made from older materials. Threadless systems are:
-
Lighter, which makes the whole bike easier to ride
-
More compatible with today’s lighter forks and frames
-
Easier to upgrade or service at any modern bike shop
3. Better Fit, Smarter Adjustability
With threadless systems, we can use spacers to fine-tune handlebar height and adjust for reach. That’s especially useful when:
-
Your child is in-between sizes
-
You want to tweak the setup for confidence (e.g. more upright for learners, more forward for trail-ready kids)
While quill stems are arguable easier for height adjustability, threadless setups also allow you to swap in shorter or longer stems down the track to match your child’s growth or riding style.
Why Some Bikes Still Use Quill Stems
Quill stems can be adjusted up and down more easily—great in theory. But in practice, this style is heavier, less stiff, and becoming obsolete. They’re more common on cheap, toy-store bikes. And while they might seem “easier” at first, they limit fit precision and often corrode or seize with time.
Real Bikes for Real Riding
At base bikes, we build real bikes—not toys. That’s why we use the same threadless headset system trusted by mountain bikers, road cyclists, and BMX riders alike. It helps your child:
-
Ride more confidently
-
Stay safe
-
Get real performance from a setup that’s designed to last
Whether your child is just starting to pedal or pushing laps at the local pump track, every part of their bike should support fun, freedom and skill-building. That includes the headset.
