Verified Compatibility

Left Lever = Rear Brake Control on the Applicable iQube

TVS iQube owner documentation identifies a rear drum brake operated through a handlebar brake lever and specifies rear-brake lever free play at the lever end. The handlebar parts catalogue places K61504003C on the left-hand side, while the front-brake master-cylinder assembly is separately catalogued on the opposite hydraulic side.

This means that for the applicable iQube configuration, K61504003C should be understood as the left-hand rear brake lever / left control lever, not the hydraulic front brake lever.

Bright Silver Finish

The suffix description “BR SIL” in TVS catalogue terminology refers to the Bright Silver finish. Buyers should compare the existing lever finish before ordering if appearance matching is important, especially if the scooter has previously had a lever replaced with a different finish or aftermarket component.

What You Receive

1 × TVS Genuine Left-Hand Rear Brake / Control Lever Assembly – Bright Silver – K61504003C.

This listing is for the lever assembly corresponding to K61504003C. The following parts are not assumed to be included unless physically supplied inside the TVS package:

• Left lever bracket
• Lever clamp
• Rear brake cable
• Brake-light switch
• Parking-brake lock / stopper mechanism
• Parking-brake spring
• Pivot bolt / special bolt
• Washers, nuts or circlips
• Handlebar grip

Related iQube Handlebar / Brake Parts

The TVS iQube parts catalogue lists K61504003C alongside several separate components in the handlebar assembly. These related numbers are useful for identification but are not included with the lever unless specifically packaged together.

Do Not Confuse This With the Complete Lever Holder Assembly

The wording “Control Lever Assy” does not mean the complete handlebar brake-control system is supplied. TVS catalogues the holder, bracket, clamp, brake-light switch, parking-brake components and rear brake cable separately.

If the scooter has accident damage around the complete left brake-control area, inspect the bracket, clamp, cable and pivot hardware before ordering only K61504003C.

When Should the Lever Be Replaced?

• The lever is bent after a fall or impact.
• The lever blade is cracked or broken.
• The pivot area has become damaged or excessively worn.
• The lever does not move freely because the lever itself is physically deformed.
• The outer end is heavily damaged after the scooter has fallen on its left side.
• The original lever has been replaced with an incorrect aftermarket shape and the scooter is being restored to the applicable factory configuration.

Rear Brake Free-Play Reference

TVS iQube owner documentation specifies rear brake lever free play of approximately 10–15 mm at the lever end for the rear drum-brake system. The adjustment is made at the rear-wheel brake adjuster rather than by bending or modifying the lever.

After replacing K61504003C, the technician should check:

• Correct lever movement
• Rear brake cable condition
• Rear brake free play
• Rear wheel free rotation after adjustment
• Brake-light switch operation
• Parking-brake lock function where equipped

Installation & Safety Guidance

The brake lever is a safety-critical control. Correct installation and brake adjustment are essential before the scooter is ridden.

• Inspect the lever bracket and pivot area for crash damage before installing the new lever.
• Inspect the pivot bolt, bush, nut and washers for wear or deformation.
• Check the rear brake cable for fraying, corrosion, kinking or abnormal resistance.
• Confirm the brake-light switch is triggered correctly by lever movement.
• Ensure the lever returns fully after release.
• Set rear brake lever free play according to the applicable TVS specification.
• After adjustment, confirm the rear wheel can rotate freely when the brake is released.
• Confirm the parking-brake mechanism engages and releases correctly where fitted.
• Do not ride the scooter until proper rear-brake operation has been verified.
• Professional installation is recommended if the complete lever/bracket/cable assembly has been damaged.

Why Correct Rear-Brake Adjustment Matters on an Electric Scooter

TVS specifically cautions that an overtightened rear brake can prevent the wheel from rotating freely and may increase energy consumption, reducing effective riding range. For this reason, lever replacement should always be followed by a proper brake free-play and drag check.

Parking-Brake Mechanism – Separate Component

The iQube handlebar catalogue shows a parking-brake lock/stopper mechanism adjacent to the left brake lever. The parking-brake lock is catalogued separately as K6321540 in the applicable parts family.

Therefore, if a customer says the “parking brake lever is broken,” first determine whether the damaged component is:

• K61504003C – main left brake/control lever
• K6321540 – parking-brake lock/stopper component
• associated spring or holder hardware

These components should not be treated as one interchangeable part.

Model-Year / Generation Caution

TVS has continued to evolve the iQube platform, including battery-capacity, electronics and hardware revisions. K61504003C is strongly verified across the 2022/ELE and subsequent S/Gen3/ST/SmartX catalogue family, but the listing does not make an unrestricted “all iQube all years” claim.

For a very recent iQube, especially a current 3.1 kWh / 3.4 kWh or later-production version, compare the existing part number or use the VIN/chassis-based TVS catalogue before ordering.

Why Use the Exact TVS Part Number?

• Left and right iQube levers are not the same component.
• The pivot shape and brake-control interface must match the correct holder.
• The rear brake cable and parking-brake system require the correct lever geometry.
• A generic scooter lever may look similar but can have different pivot, cable-seat or switch-actuation dimensions.
• Exact part-number matching reduces the risk of incorrect installation on a safety-critical component.

Genuine Replacement Advantages

• Correct catalogue reference for the verified iQube handlebar assembly.
• Correct left-hand geometry for the applicable rear brake system.
• Bright Silver finish matching the TVS catalogue description.
• Designed to work with the applicable TVS lever bracket, brake cable and parking-brake arrangement.
• Better part-number traceability than an unbranded “universal iQube lever.”

Frequently Asked Questions

Q. What is TVS part number K61504003C?
K61504003C is the genuine TVS left-hand control / rear brake lever assembly in Bright Silver used on verified TVS iQube electric-scooter configurations.

Q. Is K61504003C the left or right lever?
It is the left-hand (LH) lever. The TVS catalogue description itself states “CONTROL LEVER ASSY L.”

Q. Is this the front brake lever?
No. On the applicable iQube setup, the left-hand lever is associated with the rear drum-brake control. The front hydraulic brake/master-cylinder system is a separate handlebar assembly.

Q. What does “BR SIL” mean?
It refers to the Bright Silver finish of the lever.

Q. Does this fit TVS iQube S?
Yes. iQube family catalogues covering S configurations list K61504003C at the left control-lever position.

Q. Does it fit iQube Gen3?
Yes, the later parts catalogue covering S Gen3 / UG Gen3 continues to list K61504003C in the handlebar assembly.

Q. Does it fit iQube ST?
The shared catalogue family covering ST configurations lists K61504003C at the left lever position.

Q. Does it fit SmartX9 / SmartX11?
Later iQube parts-catalogue data covering SmartX9 and SmartX11 retains K61504003C as the left bright-silver control lever.

Q. Will it fit every latest iQube?
Do not assume universal all-year fitment. TVS has revised the iQube platform over time. For a very recent 3.1 kWh / 3.4 kWh or later-production scooter, verify K61504003C through the VIN/chassis-based parts catalogue or compare the original lever.

Q. Does the lever include the rear brake cable?
No. The applicable rear brake cable is catalogued separately, including KE170070 in the relevant iQube handlebar catalogue.

Q. Does it include the parking-brake lock?
No. The parking-brake lock/stopper is a separate component, catalogued as K6321540 in the applicable parts family.

Q. Does it include the lever bracket?
Do not assume so. The lever bracket and clamp are separate catalogue items, including K4150150 and K6150570.

Q. What should the rear brake lever free play be?
TVS iQube owner documentation specifies approximately 10–15 mm of rear brake lever free play at the lever end on the applicable rear drum-brake system.

Q. Why is the rear wheel dragging after lever replacement?
The rear brake cable may be adjusted too tightly, or another brake component may be binding. TVS cautions that the rear wheel should rotate freely after adjustment. Excessive brake drag should be corrected before riding.

Q. Is this suitable for a crash-damaged scooter?
It can replace a damaged lever when K61504003C is the required part, but crash damage may also affect the bracket, handlebar, brake cable, pivot hardware or switch. Inspect the complete control assembly.
