Choosing the Right Battery Capacity: 7.8Ah vs 10ah

The Fuel Tank of Your E-Bike

Battery capacity is measured in Amp-hours (Ah). Think of it as the size of your fuel tank. A bigger number means more range, but also more weight and cost.

7.8Ah: The City Commuter

The 7.8Ah Battery is our most popular entry-level option.

• Range: Approx 30-35 km (pedal assist)
• Best For: Short daily commutes, grocery runs, and light riders.

10ah: The Long Ranger

The 9 AHBattery offers that extra cushion.

• Range: Approx 40-50 km (pedal assist)
• Best For: Longer commutes, delivery riders, or those who use the throttle more often.

Understanding Voltebyk 250W BLDC Technology & Engineering

Every Voltebyk electric bicycle and conversion kit is engineered specifically for Indian road conditions and weather extremes. At the core of our propulsion system is a high-torque 250W Brushless DC (BLDC) hub motor that delivers instantaneous acceleration without heat buildup or mechanical friction. Paired with a 36V detachable Lithium-ion battery pack (available in 7.8Ah and 9Ah variants), Voltebyk e-bikes offer an impressive range of up to 35 km to 50 km per single charge.

Our intelligent 5-level Pedal Assist System (PAS) uses cadence sensors to monitor your pedaling effort seamlessly, supplying motor power exactly when needed on steep flyover inclines or headwinds. Additionally, all Voltebyk electrical components—including the motor, controller, battery casing, and LED display—are rated IP65 water-resistant. This ensures total peace of mind when riding through heavy Indian monsoons or dusty terrain. With dual mechanical disc brakes and safety motor cut-off levers, Voltebyk provides uncompromised safety and premium comfort for daily commuters across India.

Frequently Asked Questions

Do I need a driving license or registration to ride a Voltebyk electric cycle in India?

No. All Voltebyk electric cycles and 250W motor conversion kits are engineered to operate within the 25 km/h speed limit using a 250W BLDC motor. Under Indian Central Motor Vehicle Rules, they are legally classified as non-motorised vehicles requiring no driver's license, RTO registration, or mandatory helmet paperwork.

What is the monthly electricity cost to charge a Voltebyk e-bike battery?

A full charge for our standard 36V 7.8Ah or 9Ah lithium-ion battery consumes under 0.4 units of electricity (costing approx ₹3 to ₹5 per charge). For a 25 km daily commute, your monthly electricity cost will be under ₹100, saving you over ₹20,000 annually compared to petrol scooters.

Conclusion

If you ride less than 20km a day, save money with the 7.8Ah. If you hate 'range anxiety' or carry heavy loads, go for the 10ah.
