Thanks to its globally patented Kaptor technology, this electric trailer enhances the transportation of goods by bicycle or by hand, allowing couriers to effortlessly transport up to 350 kg.

To avoid traffic jams, CO2 emissions, and fuel consumption, K-Ryole has developed an innovative 100% electric trailer. Perfect for transporting heavy goods on the last kilometer, this trailer can carry loads of up to 350 kg. Thanks to its sensors, the system ensures that the delivery person does not feel the weight of the load. It allows businesses to save money, improve efficiency, and increase productivity without having a negative impact on the environment.

Implementation Stories

K-Ryole by K-Ryole SAS
Implemented by Stuart & Pick Up Logistics in Paris (France) in 2020

Pick Up Logistics wanted to increase its delivery efficiency and reduce its environmental impact. They have acquired progressively since 2020 a number of K-Ryole trailers to reach a fleet of more than 180 units. Each K-Ryole carries between 600 kg and 1 ton per day. They rent them to different solution providers like Stuart to perform last mile deliveries (groceries or other).


780,000 k zero-emission deliveries in 2020, performed by approximately 200 riders

K-Ryole by K-Ryole SAS
Implemented by Schenker France in Allonzier-la-Caille (France) in 2023

K-Ryole joined forces in 2022 with DB Schenker, Les Triporteurs Français and Sprint Project to offer companies a sustainable solution to the new problems of last-mile delivery in the city center. Indeed, they developed a pallet carrier trailer, which can transport up to 350 kg of load effortlessly by connecting it to a cargo bike. Able to reach 25km/h, it allows rapid delivery to hypercentres.



The environmental benefits

  • Shift to bicycles for light goods freight would allow to save 15.000 tons/year of fuel and 37.000 tons of CO2/year.

The Financial benefits

  • A delivery man can save up to 3 hours/day avoiding traffic jams and parking issues.
