Why Adding Threadlocker to Your Electric Scooter's Screws is Essential
(Because performance is useless without safety.)
Every rider has experienced it: a metallic noise, sudden play, or worse, a screw that loosens on its own after a few rides.
Between vibrations, shocks, and the power transmitted to the chassis, electric scooters are put through their paces.
And if you want it to maintain its reliability and riding precision, there's a simple but crucial step: adding threadlocker during reassembly.
What is threadlocker?
Threadlocker is a liquid product (often blue, red, or green) that is applied to the threads of a screw before tightening it.
Once dry, it forms a micro-adhesive barrier that prevents the screw from loosening due to vibrations.
In short: it's a chemical lock — invisible, lightweight, but devilishly effective.
Why put it on an electric scooter?
Scooters are high-vibration machines.
Every acceleration, braking, or road imperfection subjects the frame and screws to constant stress.
Even "tight" fasteners can loosen over time.
Threadlocker acts as an extra layer of security:
-
It prevents progressive loosening of screws.
-
It avoids parasitic noises (rattles, mechanical play).
-
It protects the screw thread against corrosion and wear.
-
And it extends the lifespan of the assembly.
On a powerful machine (like a Dualtron, Nami, or Boyueda), it's essential.
Where to apply it?
You don't need to put it everywhere, but some areas are priorities:
-
The folding clamp / bottom of the stem
→ High-stress area: this is where vibrations are most intense. -
Brake calipers
→ To prevent them from moving or loosening under braking. -
Mudguards and light brackets
→ Small screws often experience jolts. -
The motor mount, suspension, and deck
→ Especially if you've already noticed play.
Tip: blue threadlocker (medium strength) is sufficient for 95% of applications.
The stronger red is reserved for permanent or critical fasteners (not to be disassembled often).
How to apply it correctly?
-
Clean the threads
-
Remove dust, grease, or old residues.
-
Threadlocker only adheres well to a clean surface.
-
-
Apply a drop
-
No need to apply a lot: a thin layer on 2–3 threads is sufficient.
-
-
Screw and tighten normally
-
The product takes effect upon assembly, then dries in a few hours.
-
-
Allow to rest
-
Avoid riding immediately after reassembly: allow at least 12 hours for optimal hold.
-
Mistakes to avoid
-
Too much product → risk of overflow or complete thread blockage.
-
Using red on a screw that needs to be regularly disassembled.
-
Applying to a dirty or greasy thread: the product will not stick.
-
Neglecting the torque: threadlocker does not replace proper tightening.
In summary
Threadlocker is a minor detail, but it makes all the difference between a reliable scooter and a dangerous one.
It's a simple, inexpensive, and essential solution to avoid:
-
Play in the stem,
-
Screws loosening,
-
And annoying mechanical noises.
A tube costs less than €10, and can secure your entire machine.
So before your next ride, check your fasteners... and think threadlocker.
