The Cstrider Story

Reclaim
the Waterways

The water is the shortcut. This is the story of a smart, silent, emission-free ferry, and the cities it reconnects.

01

Chapter One

The Gap

In 1890, the roddarmadamer rowed commuters across Göta Älv. Then cities turned their backs on the water. Bridges got longer, detours got slower, and the waterways, the original streets, fell silent.

Today a crossing of 300 metres can mean a detour of 10 kilometres. The gap in urban mobility is real. But the water is still there, waiting.

Don't just bridge the gap. Glide over it.

Chapter Two

The Virtual Bridge

Cstrider transforms underutilized waterways into dynamic transport networks, a scalable system of autonomous electric ferries that connect neighborhoods at a fraction of the cost of traditional infrastructure.

95%

Less energy

Lightweight design and electric propulsion cut energy use by up to 95% versus alternative travel modes.

0

CO2 Emissions

Silent, climate-smart, zero-exhaust gas, supporting the EU goal of cutting transport emissions 90% by 2050.

<1.5%

Of a bridge cost

A fraction of the CAPEX of bridges or tunnels, and less than half the cost of larger electric ferries.

Autonomous ready

Equipped for autonomous operations: future-proof, safe, efficient.

Infrastructure that adapts

Start with a pilot, scale the fleet to match demand. No heavy construction.

The blue highway

Your street. Just wetter. New shortcuts on existing waterways.

Seamless city. Limitless water.

Scenario Two

This is an example of how a virtual bridge can revolutionize public transport. Five small electric ferries turn a 20-minute detour into a 4-minute crossing, with a departure every two minutes, at a fraction of the cost and time it takes to build a bridge.

The problemToday I go the long way around — tram over Götaälvbron, or bus and bike. It costs me roughly 20 extra minutes each way. A bridge is expensive and takes years to build.
