Built by riders

We made the app
we needed.

Electric unicycle riders travel on the edge of what most navigation apps understand. We have different chargers, different roads, different physics. Flow exists because we built it for ourselves — and then opened it to everyone who rides.

The problem

No app understood
how we charge.

EUCs, e-scooters, and onewheels don't use DC fast chargers. They run on J1772, RV hookups, and ordinary 110V outlets — the same infrastructure hikers use at state parks and the same plugs you find at any campground. Every existing navigation app either ignored those sources or routed us to incompatible DC stations.

So we built Flow: a navigator that knows L1, L2, and RV power, skips DC-only stations, chains stops into viable long-distance routes, and keeps the cockpit readable at speed. Then we took it on the Pacific Coast Highway to prove it worked.

The community

PEVRA — Personal Electric
Vehicle Riders Association.

PEVRA is the community behind Flow. We organize rides, advocate for PEV access on bike infrastructure, and share the knowledge that makes long-distance electric riding possible. Westwheel — our annual coastal expedition — is where Flow gets its hardest real-world test.

Flow is built to serve every PEV rider, not just the PEVRA community. But PEVRA's ethos — shared knowledge, no gatekeeping, celebrate the ride — runs through every design decision we make.

How we build

Principles, not features.

Trust first

The cockpit shows what your wheel actually knows. Charge estimates are conservative. We would rather you arrive with margin than chase an optimistic number off a cliff.

Readable at speed

Every number earns its place. If it's on screen, you should be able to read it in under 1.5 seconds without slowing down.

Built in public

Field validation before every release. Real riders on real roads catch what a test lab misses. PEVRA community feedback drives the roadmap — not analytics dashboards.

Say hello

Questions, feedback, or bug reports.

We read everything. If you found a charger we missed, a road that should be in the system, or something broken — tell us. Email is the fastest path to the people who can act on it.
