The battery voltage must match your e-bike system and should not be mixed with a different voltage setup.In general:
For example, if your motor and controller are built for a 48V system, you should choose the 48V battery version. Choosing the wrong voltage may result in poor performance, system instability, or the battery not working properly.
This battery is equipped with a 60A BMS, which helps provide more stable power output and improves reliability during both everyday riding and higher-load use.It is also built with LG / Samsung premium cells, offering better consistency, stability, and long-term performance.
Overall, this battery is designed not just for capacity, but for dependable power delivery, improved safety, and long-term reliability.
This battery features a more compact structure and supports multiple mounting positions, including Top Tube and Down Tube installation, making it easier to fit different frame designs.It also comes with a compatible mounting plate / bracket system, which helps make installation easier and more secure. Once installed, the battery stays more stable during riding while also offering better safety and anti-theft support.
It is repaired locally under the 1-year warranty — service centres in the UK, US, and the Netherlands. Batteries never ship overseas for repair.
Actual range depends on several factors, including battery voltage and capacity, rider weight, road conditions, riding speed, temperature, and motor power.Depending on the battery version and the motor power it is paired with, the estimated riding range is typically around 30–70 km, with some higher-capacity versions reaching even more under the right conditions.For charging, this battery supports 5A fast charging, and most versions can be fully charged in about 4–5 hours. This helps reduce waiting time and makes it a practical choice for commuting and frequent daily use.
800–1,000 full charge cycles depending on model — roughly three to five years of daily commuting. One of our riders has 20,000 km on a KirbEbike system in two years.
All KirbEbike core kits from 500W to 4000W share this battery ecosystem. (EZ Rider and the Mid-Drive controller system use their own packs — the Mid-Drive pairs specifically with the 48V 30Ah.)
