About Motorbike
The Battery
The Ampace JP40 battery, configured in a 30s14p setup, boasts a capacity of 54Ah at 111V, providing 5kWh of usable energy. When paired with the electric motorbike specifications, it delivers a continuous power output of 20kW and can achieve a peak power of 63kW (±6kW). The battery is effectively cooled through its metal frame and features force air cooling, ensuring optimal performance, especially when used with the QS Motor 273.
Motor
The motor used for this build is the QS Motor 273, which is rated at 8-10kW depending on speed. This electric motor has been modified to handle up to 18-20kW (300A phase current) continuously and can peak at 60kW (1200A phase current) for 20 seconds. This impressive performance is achievable thanks to the use of statorade and hub-sinks, which are particularly effective at high speeds. Additionally, when paired with the Ampace JP40 battery, the overall electric motorbike specifications are significantly enhanced.
Controller
The controller used in this build is the EZ kontrol controller C961200, which outputs 600A battery current at 111v and a maximum phase current of 1200A, perfectly complementing the specifications of the Ampace JP40 battery and the QS Motor 273 for an optimized electric motorbike experience.
Liquid-cooling
The electric motorbike, equipped with the QS Motor 273, features a liquid cooled system for the controller, which ensures optimal performance across various scenarios. With the reliable Ampace JP40 battery, this model showcases impressive electric motorbike specifications.
Frame
The frame of the electric motorbike was designed in CAD to be the most lightweight possible, yet sturdy enough to handle jumps off-road. Weighing an impressive 18kg on its own, the entire electric motorbike, equipped with the efficient Ampace JP40 battery, has a total weight of just 70kg. The electric motorbike specifications highlight its robust design, complemented by the powerful QS Motor 273 for optimal performance.
Secondary 14.4V battery
The electric motorbike, equipped with specifications like the QS Motor 273, features a secondary battery to supply power to all the extra accessories on the bike. These include a water pump, headlights, and phone charger. It also utilizes the Ampace JP40 battery, providing a 12v outlet at the bottom of the bike, which can be used to charge the battery or discharge it at a maximum of 30A before the internal fuse is triggered!

Specifications
Battery: Ampace JP40 battery (420 cells) features a 30s14p configuration with a capacity of 111V56Ah, offering 5kWh of usable power. It delivers an available peak discharge power of 98.2kW (980A), while the used peak discharge power is 62.6kW (600A). The continuous discharge power stands at 21.8kW (200A), and the peak charging power is 19.8kW (175A), with continuous charging power at 3.1kW (28A). The peak phase current reaches 1200A, and the continuous phase current is 300A. When considering electric motorbike specifications, the estimated range is 75km at 110km/h or 120km at 65km/h. The estimated charging time is 6 hours at 10A or 3 hours at 20A (0-100%). The estimated internal resistance of the Ampace JP40 battery is 13mOhms. Cooling is achieved through a conductive and forced air cooling method. The maximum calculated speed is 180km/h at 115V, with real-world conditions yielding a maximum speed of 165km/h at the same voltage. Additionally, there is a 14.4V 30Ah battery available for accessories. The electric motorbike features three speed modes: the first mode is limited to 25km/h, 2kW, and a phase current of 150A; the second mode allows a speed of up to 100km/h, with 21.8kW and a phase current of 400A; and the third mode offers unlimited speed, reaching 62.6kW and a phase current of 1200A. This setup is compatible with the QS Motor 273.
