UPS has said that it is also trialling electric bikes from other manufacturers for its trials but has not disclosed the names.

The UPS eQuad has an electric-assisted top speed of 25 kilometres (15.5 miles) – if the delivery person pedals harder they can go faster – and can haul up to 200 kilograms or 441lbs of packages.

The company intends on scaling up the electric bike operations in response to growing consumer demand for e-commerce, and to supplement its existing truck fleet.

UPS is trialling the electric vehicles in seven European markets, including the UK.

Luke Wake, VP of Fleet Maintenance and Engineering at UPS said: “There are more and more opportunities for zero-emission solutions like this that can alleviate inner-city congestion.”
