If your TVS iQube has started making strange noises, it can feel unsettling—especially because electric scooters are usually silent and smooth.
When I first heard a faint rattling from my iQube, I thought it was minor. A week later, it became louder, and that’s when I learned that every sound in an EV has a reason.
Electric scooters operate quietly, so even a soft whirr or click can signal something that needs attention.
In this guide, I’ll share what I discovered through experience and research—how to identify, diagnose, and fix different noises before they turn into costly problems.
1. Identify the Type of Noise Coming from Your TVS iQube
Start by listening carefully. Is it a whirring, rattling, squeaking, or grinding sound? Each noise point to a different issue.
A mild hum is normal—most electric motors produce around 50–60 decibels when running. But if you hear a metallic vibration, high-pitched squeal, or rhythmic clunking, something’s not right.
Note when the noise appears: while accelerating, braking, or on uneven roads.
For example, a hum during acceleration often relates to the drive belt, while a clunking sound on bumps could indicate suspension or panel looseness.
Identifying when and where it happens is the first step toward a targeted fix.
2. Check for Loose Panels or Underbody Components
Many iQube owners mistake rattling or buzzing noises for mechanical issues when it’s just a loose panel or bolt.
The scooter’s plastic and fiber body panels can vibrate over time, especially if you ride on rough roads.
In my case, the culprit was a loose screw under the left footrest. Once tightened, the noise disappeared completely. Nearly 40% of EV noise complaints are caused by vibrations from panels or underbody covers.
Inspect the side panels, footboard screws, and underbody plates. Even small gaps can amplify at higher speeds. Adding a thin rubber washer between contact points can reduce friction noise.
3. Inspect the Belt Drive and Motor Assembly
If you hear a squealing or whining sound, the drive belt or motor alignment might be off. The TVS iQube uses a belt-driven hub motor system, which requires proper tension.
A loose or dry belt can slip and create noise, while an overtightened one strains the motor. Over time, this can reduce performance and efficiency by up to 5–10%.
To check, place the scooter on its main stand and rotate the wheel manually. If you notice uneven resistance or hear squeaks, it’s time for an adjustment.
Belt maintenance should always be done at an authorized TVS service center, as incorrect tensioning can damage the drivetrain.
4. Examine the Brake Pads and Drum Assembly
Brake noise is another common concern. A squealing sound while braking often points to worn-out brake pads or dust buildup inside the drum.
The iQube’s regenerative braking can also slightly alter braking feel, but it shouldn’t make loud noises.
After every 5,000–7,000 km, inspect the brake shoes for wear. If they appear glossy or uneven, replace them. Sometimes, simple cleaning with brake cleaner spray removes dust and eliminates the squeal.
Also, check if the brake lever returns smoothly. A sticky lever can cause partial contact between the pads and drum, producing a mild grinding sound.
5. Look for Suspension or Fork Noise on Rough Roads
If you hear a thudding or clunking sound when riding over bumps, inspect the front fork and rear shock absorbers. Worn bushings or loose bolts can cause this.
I once ignored a dull clunk for weeks, assuming it was a road issue. Later, a service technician pointed out minor oil leakage in the left fork, which amplified vibrations through the handlebars.
Suspension wear doesn’t just create noise; it can increase vibration levels by nearly 30%, affecting handling and comfort.
Check for oil stains or uneven bounce when pressing the scooter down. If it feels spongy or makes noise, get it serviced immediately.
6. Inspect the Wheels and Bearings
A humming or grinding sound that changes with speed usually points to wheel bearings. Over time, bearings wear out or lose lubrication, especially after riding in rain or through puddles.
Lift the wheel slightly and rotate it. If it doesn’t spin freely or you hear friction, the bearings need attention. Replacing them costs around ₹400–₹800 per wheel, a small price compared to long-term damage.
Also, check wheel alignment and tire pressure. An unbalanced wheel can make a rhythmic sound that feels like a mechanical fault.
7. Visit an Authorized TVS Service Center
If you’ve checked everything and the sound persists, it’s best to let experts inspect it. Authorized TVS centers use diagnostic tools and ECU scanners to detect underlying motor or controller issues that may not be visible externally.
They can also ensure your scooter’s firmware and software are up to date—TVS occasionally releases updates that improve motor calibration and noise reduction.
A full check-up restores smoothness and protects your scooter’s battery and warranty coverage.
Final Thoughts
Strange noises in your TVS iQube don’t always mean serious trouble. Most issues come from loose parts, minor misalignments, or worn components.
Early attention prevents wear and keeps your scooter performing silently and efficiently.
In my experience, treating any new sound as an early warning has saved me both time and money.
With regular inspections and timely servicing, your iQube can stay as quiet and enjoyable as the day you first rode it.
