Design Specs

Target UserYacht owners and marina residents requiring efficient dock-to-store transport.
MechanismTelescoping handle system with 90-degree folding rear legs.

Material & Build

  • Frame: Rigid plastic composite produced via injection molding.
  • Corrosion Resistance: Marine-grade stainless steel hardware.
  • Capacity: Engineered to carry up to 25kg of cargo.
The Challenge

Bridging Land and Sea

Yacht owners often face a logistical challenge: transporting groceries and supplies from local markets to their docked vessels. The journey typically involves a walk or ride from the store to the marina, followed by navigating narrow docks.

The goal was to create a hybrid vehicle that functions as a stable shopping cart in the store and transforms into a rideable bicycle for the return journey, all while being compact enough to stow on board.

The Solution

Cart-to-Bike Conversion

I engineered a unique folding frame mechanism where the rear wheels rotate 90 degrees to tuck under the shopping basket, converting the wide cart footprint into a streamlined bike profile.

Shopping Mode

Features a telescoping handle and swivel casters for effortless maneuverability in tight store aisles.

Riding Mode

Deploys into a stable tricycle configuration with ample cargo space, perfect for dockside commuting.
