Quick Summary & Direct Answer

Real-world electric cycle range depends heavily on drive mode: Pure Throttle typically delivers 35 to 60 km per charge, while Pedal Assist System (PAS) delivers 55 to 110 km on the exact same battery by combining human effort with intelligent motor assistance.

Understanding Watt-Hours (Wh) Calculation

Range is determined by battery energy capacity in Watt-Hours (Voltage × Amp-Hours). A 36V 10.4Ah battery contains 374.4 Wh. In throttle mode, consumption averages 7–9 Wh/km; in pedal assist mode, consumption drops to 3–4 Wh/km.

Factors Impacting Real-World Range in India

Rider body weight, tyre inflation pressure (keep at 40 PSI), frequent stop-and-go city signals, headwinds, and elevation gradients all influence final mileage.
