What it is
A multi-modal route planner for cyclists who already use trains, buses, and ferries to extend their rides. It plans three options — chill, balanced, fast — and explains the trade-offs.
How it routes
It runs a real shortest-path search across a city graph that knows three things bike apps usually forget: cycling stress (greenway vs. sharrow), elevation grade, and whether a transit line lets you roll your bike on. The "AI" is multi-objective optimization plus a plain-English explainer.
The Ride Resonance preview
An animated scrub through the route. Bike legs show a wheel spinning at your cadence with scenery that matches what's out the window. Transit legs glide past stations. Effort, grade, and a coach's callout update in real time. Adjust a slider — everything reshapes.
What it isn't
This is a labs demo. The map is Greypoint, a fictional city designed to surface real cycling trade-offs. No GPS, no accounts, no analytics, no network calls. Everything runs in your browser.
