Relay
Relay
Electric bikes, scooters, and mopeds are revolutionizing how we move through cities, but infrastructure development lanes lags behind. Relay combines turn-by-turn navigation with spatialized real-time hazard alerts: blindspot monitoring for micromobility. Relay's hands-free audio interface helps riders of all abilities stay eyes-up and alert on busy urban roads.
Relay is 100% audio based, so cyclists can keep their eyes on the road. Forgot where you're turning? Click your headphones once to hear the next direction reread.
Monitor cars without looking over your shoulder. Relay listens for nearby cars and synthesizes a spatialized representation in your headphones.
Relay ties user-input alerts like construction, broken glass, or heavy traffic to GPS locations, and builds future routes to avoid hazards or alert riders when nearby.
The proliferation of micromobility devices is getting pedestrians out of cars and onto the street, but road infrastructure hasn't caught up. Especially in American cities, bike lane networks are patchy. Cyclists and micromobility vehicles are forced to share lanes with cars and trucks on busy urban corridors. As micromobility grows so do rates of clashes, collisions, and injuries.
Shared e-bike programs like New York's Citi Bike have made a significant contribution to the growth of micromobility in North America. In 2023, shared micromobility trips in the U.S. reached 133 million, a 16% increase from the previous year, with the surge largely driven by the continued growth of e-bike trips on larger station-based systems. 1
In America alone 1,084 bicyclists were killed in crashes with motor vehicles in 2022. Bicyclist deaths have increased 75% since 2010. 2 E-bicycle injuries doubled each year from 2017 through 2022; e-scooter injuries rose by 45 % annually over the same period. 3
Sunset Boulevard thrums with movement. Cyclists, e-scooters, cargo bikes, and electric mopeds weave through dense traffic, from delivery trucks to rideshares. After years of promises, L.A.'s protected bike lanes are still patchy—riders must constantly negotiate with cars for space on roads crowded with single-occupancy vehicles.
Lina, a nurse commuting on her e-bike, merges to her right without glancing over her sholder - slotting neatly into the gap between two SUVs. A soft spatial chime in her wireless earbuds shifts left as the delivery truck she merged to avoid turns off Sunset. Around her, dozens of riders trust the same invisible system: ambient sounds layered seamlessly into their environment, a sixth sense for the motion around them.
Thanks to Relay, urban streets no longer belong only to the bold. The fixie kids and lycra racers still ride, but now they're joined by parents on cargo bikes, and seniors on scooters, moving with confidence. Cars still pack highways, but in town, short trips have gone lighter, faster, and cleaner. Micromobility is no longer a fringe solution — it's how the city moves.
