[Moto] The 'hole' bike technology now on a police hybrid electric scooter

[#Wittels-]

The WMC300FR First Responder electric hybrid scooter inherits the technology of the WMC250EV, an electric motorcycle designed to reduce aerodynamic drag and break the world speed record thanks to a longitudinal hole through it.

The WMC300FR First Responder electric hybrid scooter uses an electric motor to move at low speeds and the aerodynamics of the Venturi hole that runs through it to save gas when speed is increased.
White Motorcycle Concepts (WMC) has introduced the WMC300FR First Responder, a revolutionary electric hybrid scooter that uses the same aerodynamic technology as the WMC250EV, the “hole bike”, which has a longitudinal channel that runs through it to improve airflow. . This scooter is specifically designed for use as a fully operational first responder vehicle to be incorporated into emergency services.

The British company based in Northamptonshire and founded by its CEO Rob White, has based the WMC300FR First Responder on the same patented technology with which it aims to break the world speed record with an electric motorcycle, currently owned by Voxan and his Wattman , over the next 12 months. In this case, the objectives of this vehicle are not to achieve high speeds but to increase autonomy, which allows it to be viable for emergency service fleets, reducing operating costs and the carbon footprint of companies.

The tricycle scooter has been developed in collaboration with Northamptonshire County Police and the cooperation and guidance of Northants Force Police Chief Nick Adderley. It is the result of almost three years of research on the reduction of aerodynamic resistance that, together with the latest generation of hybrid technology, will be able to reduce CO2 emissions by up to 50%.

 

Air is channeled into the venturi hole thanks to the special shape of the front fenders.

The scooter features WMC's patented Venturi duct, which reduces drag by letting air pass through the vehicle, instead of bypassing it. This system is aided by aerodynamic front fenders that channel air into the hole, reducing overall frontal drag which means it requires less energy to propel. The scooter is based on the Yamaha Tricity 300 which uses a 292cc single cylinder four-stroke engine. But the WMC300FR First Responder also has an electrical system powered by two removable 56 V 12 Ah (672 Wh) lithium-ion batteries supplied by EGO.

The electrical system is powered by removable 672 Wh capacity batteries.

The hybrid assistance system has a power of up to 5 kW and operates predominantly at low speeds, which improves acceleration and range. When speed is increased, the aerodynamics of the Venturi duct come into play, reducing fuel consumption. Batteries can be quickly charged in multiples of six with a standard three-pin plug, eliminating downtime.

In most countries, the scooter can be driven with a car license, which is also an advantage for fleet management companies as they do not need to hire staff with a specific motorcycle license.
