The limited driving range of electric two-wheelers remains a major barrier to their wider adoption, and India's rapidly growing electric two-wheeler market makes this limitation increasingly consequential. Conventional regenerative braking systems recover kinetic energy through the traction motor alone, so recovery efficiency falls under variable braking conditions. This paper proposes an Electrical Combi Braking System (ECBS) that combines electronic brake-force distribution with dual-motor regenerative energy recovery for electric motorcycles. The architecture retains a rear-wheel BLDC traction motor for propulsion and adds a dedicated front-wheel BLDC machine that operates solely as a generator during braking; brake-lever input is regulated by a voltage-controlled regenerative braking controller that delivers proportional braking torque while converting kinetic energy into stored electrical energy. A dual-pack battery management system distributes the recovered charge across alternating cycles to preserve battery health, and a solar-assisted auxiliary module is proposed as a supplementary charging source. An eleven-equation mathematical model of vehicle dynamics, weight-transfer-based brake-force allocation, regenerative power generation, and electrical braking torque is developed, and a MATLAB/Simulink-consistent preliminary simulation — including a parameter sensitivity analysis — is used to estimate recovered energy, battery state-of-charge recovery, and range gain. Under the stated assumptions, the simulation indicates approximately 30% greater energy recovery than a conventional single-motor system and an estimated 10-12% range improvement in urban driving, motivating hardware validation on the Donther electric-motorcycle platform.
