Problem
Everyday commutes and family journeys often rely on cars for short trips under 8 km, which account for 68% of car journeys, leading to traffic congestion, high running costs averaging £3,834 annually, and time lost to delays. Traditional bike trailers lack power assistance and suffer from stability issues, making them impractical for carrying heavy loads or children in urban environments.
Solution
CONVOY provides a range of lightweight e-trailers and standard trailers that turn any adult bike into a cargo-carrying e-bike or premium e-longtail. The e-Trailer includes a 250W Bafang motor, a 360Wh battery providing a 30km range, and a 50kg or two-child load capacity, all in a 14kg package that attaches in seconds via a tool-free twin latching axle clamp system. Its patent-pending Mirror™ active rear-wheel steering and Follow™ inline architecture ensure the trailer tracks the bike perfectly through tight turns, reducing wobble and improving safety. The trailer folds for compact storage, includes smart features like over-the-air updates, digital locking, and ride tracking via an app, and is compatible with most metal-framed bicycles with wheel sizes from 26" to 29".
Target Audience
Primary customers are urban commuters and families with children who want to replace short car journeys with a versatile, powered cargo-carrying bike solution, as well as existing e-bike owners seeking to upgrade their bike's cargo capacity without purchasing a dedicated longtail e-bike.
