Evri has reported full uptime and no servicing requirements during a winter pilot of four-wheeled e-cargo bikes from Vok Bikes, conducted in the UK during the peak delivery season.
The trial, which ran from November 2025 to January 2026, saw couriers deliver around 14,000 parcels using the vehicles. The fleet covered approximately 1,150km in total, averaging about 16km per vehicle per day.
According to Evri, the bikes required no maintenance throughout the trial, despite daily use, high workloads and winter conditions.
Luke Turnbull, e-cargo operations manager at Evri, said the results highlight the growing viability of cargo bikes in last-mile logistics. “This trial showed that cargo bikes are now capable of offering a comparable alternative to traditional vans in terms of reliability and vehicle load, while outperforming on productivity metrics,” he stated.
“While vans remain better suited for higher mileage, there is a clear operational, environmental, social and cost benefit to deploying e-cargo bikes on dense, ultra-urban routes.”
The company also reported a 15% increase in parcel deliveries per hour compared with van-based operations. It attributed this to greater route flexibility, the ability to use bike and bus lanes, and reduced time spent parking and accessing delivery points.
Evri said the results come as congestion in UK cities increases and operating costs for van-based delivery continue to rise, supporting a shift toward wider adoption of cargo bikes in urban logistics.
Vok Bikes said the performance was partly due to its drivetrain design, which differs from traditional cargo bikes that rely on bicycle-based components.
Chris Cayford, operations manager at Vok Bikes London, said, “Our pedal-by-wire system with sealed electric components removes many common failure points – no chains, no exposed gearing and no high-wear mechanical parts.”
Evri currently operates more than 113 cargo bikes in London and has outlined plans to expand its e-cargo fleet to 3,000 units over the next decade.
