What Speed for Which Gear?

[DeDelilah]

The gear shift is located on the right side, and most designs are five-speed vehicles. First gear accelerates to around 10 km/h, meaning speeds from 0 to 10 km/h fall within the first gear range. Second gear covers 10-20 km/h; third gear, 20-30 km/h; fourth gear, 30-40 km/h; and fifth gear, 50 km/h up to the maximum speed. Below are the relevant details: 1. Start in low gear, typically using first gear, with an economical speed range of 15-20 km/h. Suggestion: Shift from second to first gear at speeds no higher than 18 km/h. 2. For continuous uphill driving, use low gears (1st or 2nd) to ensure sufficient vehicle power. The economical speed for second gear is 25-40 km/h. Suggestion: Shift from third to second gear at speeds no higher than 35 km/h. 3. For continuous downhill driving, use low gears (2nd or 3rd) to prevent excessive speed. This avoids prolonged brake usage, protecting the brake pads. The economical speed for third gear is 40-60 km/h. Suggestion: Shift from fourth to third gear at speeds no higher than 55 km/h. 4. The economical speed for fourth gear is 60-75 km/h. Suggestion: Shift from fifth to fourth gear at speeds no higher than 70 km/h. Fifth gear is suitable for speeds above 75 km/h.
