Calculate electric motorcycle power with our online tool

Creating an electric motorcycle poses a significant challenge for engineers, mainly in the meticulous task of identifying compatible components. With the electric motorcycle industry evolving swiftly and numerous brands venturing into various categories, there's a pressing need to simplify this intricate process. Fortunately, T&D has created an algorithm designed to improve efficiency in this process, complemented by our meticulously designed powertrains tailored to the unique demands of individual development projects. Our aim is to streamline product development with tailored solutions and advanced calculations.

What is T&D’s algorithm? 

This year, we introduced a novel service, an advanced algorithm designed to calculate the ideal attributes of components within a complete system for teams creating and manufacturing electric motorcycles. Leveraging extensive research dedicated to crafting our complete drive systems for the e-motorcycle industry, the team can deliver a customized solution precisely crafted to match specific requirements.

How it operates 

By inputting key attributes (i.e. curb weight, tire size, gradability, etc.) for your e-motorcycle project into the configurator, product developers and engineers can swiftly generate a detailed report that identifies precise calculated data for the project's optimal motor, battery, and more, alongside accurate projections for acceleration time, gradability and range, calculated at 80-50% of maximum speed.

This data serves as the foundation for collaboration between ourselves and product development teams, aiding in confidently determining the best complete set of components for the electric motorcycle powertrain including the motor, battery, HMI, charger, and controller, to achieve the desired outcomes.

Streamlining Drive System Recommendations

T&D aims to offer the most suitable drive system recommendations in the most efficient way possible. Utilising the expertise of a team of highly experienced engineers, the algorithm emphasises all the key parameters crucial to consider when designing an electric motorcycle, including the design, analysis, implementation, optimization, and evaluation. 

Here’s where you come in. This publicly available tool is a first of its kind in electric motorcycle powertrains. We would love to know what people in the industry, including engineers, product developers, technicians, mechanics, students and more, think.
