With continuously rising fuel prices in Pakistan, many people are now considering electric bikes as an affordable and smart alternative to petrol motorcycles. Before purchasing an e-bike, it is important to understand the actual running cost, battery performance, and long-term savings.

Petrol Bike vs Electric Bike Running Cost

A traditional 70cc petrol motorcycle runs an average of 55 kilometers per liter. With petrol priced around Rs. 415 per liter, including engine oil and filter expenses, the average running cost becomes approximately:

• Rs. 8.50 per kilometer

On the other hand, an electric bike with:

• 1000W to 1500W motor
• 2.2kWh Lithium Iron Phosphate (LFP) battery

can travel up to 100 kilometers on electricity costing around Rs. 125 (approximately 2.5 electricity units).

This means the average running cost of an electric bike is only:

• Rs. 1.25 per kilometer

This makes electric bikes significantly cheaper to operate compared to petrol bikes.

Why Lithium Iron Phosphate (LFP) Batteries Are Better

Lithium Iron Phosphate (LFP) batteries are considered safer, longer-lasting, and more reliable for electric bikes.

If the battery is:

• Not charged above 90%
• Not discharged below 20%

then:

• Electricity usage reduces to around 1.75 units costing approximately Rs. 88
• Battery lifespan increases significantly
• Battery performance decreases only around 30% over 7 years (approximately 5% annually)

Battery Performance in Summer and Winter

Weather also affects battery efficiency.

During winter, when temperatures drop near 10°C, LFP battery performance may temporarily reduce by up to 15%.

Under recommended charging conditions (20%–90%):

• In summer: up to 70 km per charge
• In winter: around 60 km per charge

can easily be achieved.

Recommended Electric Bike for Daily Use

If your average daily travel is around 50 kilometers, experts recommend choosing:

• 1000W to 1500W motor
• Minimum 2.3kWh LFP battery
• Maximum speed between 50–55 km/h

This setup provides the best balance between performance, battery life, and efficiency.

How to Increase Battery Life

To maximize battery lifespan:

• Avoid charging above 90%
• Avoid draining below 20%
• Use normal charging cycles
• Keep the battery away from extreme heat

Following these practices can allow you to use the same battery for nearly 7 years without replacement.

Long-Term Savings with an Electric Bike

If properly maintained, an electric bike can travel approximately:

• 125,000 kilometers over 7 years

Compared to a 70cc petrol motorcycle, this can save nearly:

• Rs. 900,000 in fuel expenses

After 7 years, replacing the LFP battery may cost around:

• Rs. 125,000

Even after battery replacement, the overall savings remain very high.

Best Battery Size According to Daily Travel

For Daily Travel Up to 50 KM

Recommended:

• 2.3kWh LFP Battery
• 1000W–1500W Motor

For Daily Travel Between 70–80 KM

Recommended:

• 3.5kWh LFP Battery

A larger battery provides better range and reduced charging stress.

Electric Motor Power Comparison

Electric motor power can roughly be compared with petrol engine sizes:

Electric Motor	Equivalent Petrol Engine
1000W Motor	70cc Engine
1500W Motor	100cc Engine
2000W Motor	125cc Engine
3000W Motor	200cc Engine

Advantages of Electric Bikes

Lower Running Cost

Electric bikes cost far less per kilometer than petrol bikes.

Eco-Friendly

They produce no smoke or harmful emissions.

Quiet and Smooth Ride

Electric motors provide silent and comfortable riding.

Less Maintenance

No engine oil, clutch adjustments, or frequent servicing required.

Better for Daily Commuting

Ideal for office workers, students, and delivery riders.

Conclusion

Electric bikes are becoming a practical transportation solution in Pakistan due to increasing petrol prices and lower running costs. With proper battery care and the right motor selection, an e-bike can provide reliable performance, long-term savings, and environmentally friendly transportation for many years.
