E-Bikes Category #1 Ranked
Aventon Aventure.2 in blue color, right-facing side profile view

With its specialized steel frame geometry, the TVS Raider 125 Flex-Fuel delivers an incredibly composed and comfortable ride for daily commuters. The overall weight of 123 kg gives the chassis a planted feel on tight curves while maintaining a balanced distribution of mass. Its solid construction makes it an excellent option for riders prioritizing longevity and street comfort.

Riding Comfort Tip

Adjust the handlebar height and seat position to customize your posture. Keep tires inflated to recommended levels to maximize efficiency and range.

Performance is driven by a high-output 11.38 PS motor that runs silently without mechanical noise. With a maximum velocity of 99 km/h, it easily keeps up with the flow of fast city traffic. Front telescopic dampers handle broken pavement with ease, while the motor maintains linear torque up hills.

Performance Comparison: TVS Raider 125 Flex-Fuel vs Peers

Metric TVS Raider 125 Flex-Fuel Standard Peer
Kerb Weight 123 kg Average Weight
Top Speed 99 km/h Standard Speed

Energy storage is managed by a high-capacity 12 V (Lead-Acid) battery pack. Recharging the battery from empty to full takes about N/A using standard chargers. Real-world tests show that the large capacity delivers a range of up to 62 km/l on Eco assist.

Riding Caution

Do not ride through deep standing water where levels rise above the wheel hub. Submerging the electrical components can bypass the rubber seals, resulting in controller shorts.

Reliable stopping security is managed by dual disc brakes, ensuring consistent control on wet pavement. Tubeless tires provide excellent grip on slick streets, and the simple mechanical layout keeps maintenance costs low.
