Very good cosmetic/mechanical condition, under 1,500 miles.
Issue:
The company went under, and the bike’s electronics were tied to their app. That app mostly stopped working, so the bike is effectively “bricked” unless you use a workaround (details below).
Why I'm selling:
I don’t have the time to finish a controller swap.
What works now:
I can still ride it by binding/unbinding in the legacy Async app (still downloadable). It’s clunky, but it does work.
Why it’s a great project:
The hardware is excellent (frame, wheels, brakes, and a huge battery).
A new e-bike controller + display swap (KT/Lishui/etc) will free it from the app.
The battery is a Phylion 46.8 V, 39.2 Ah (~1835 Wh) pack—tons of range. It should work fine with a common 48 V controller.
Work I’ve already done:
I opened the bike up, labeled the connectors, and documented what’s what (battery leads, motor phase wires, hall sensor plug, brake cutoffs, lights, etc.). I realized I’m out of time/energy to finish it myself.
Includes:
Bike as shown, sold as-is.
Charger
End-rack
Equipment for maintenance
Perfect for:
A tinkerer or e-bike tech who wants a premium scrambler-style platform and doesn’t mind installing a generic 48 V controller + small display + throttle to bring it back to life (or parting for battery/wheel if that’s your thing).
