Summary

    This is a front-hub electric conversion for Brompton's new G-Line, and it blows the socks off Brompton's own electric offering. Keep the fold and the portability you bought a Brompton for, and add proper electric assist you can even travel with.

    • Fold it, fly with it: runs on LiGo 10X batteries, 99Wh modules that are carry-on and plane-legal. Carry three for the day (about 300Wh, roughly 30 to 37 km / 19 to 23 mi) or stack up to 800Wh for real range (roughly 80 to 100 km / 50 to 62 mi), then break it down for the flight.
    • Assist that feels natural: optional torque sensing responds to how hard you pedal, or keep it simple with basic PAS or throttle-only.
    • Regenerative braking: a bi-directional throttle slows the bike and puts charge back into the battery, for more control on descents and a bit more range.
    • Clean, integrated install: a purpose-made controller mount and torque arm off the front fork, optimized cable lengths, tidy routing. It looks like it belongs there.
    • Reversible and warrantied: a bolt-on front-wheel conversion that doesn't modify your frame or drivetrain, so you can return your G-Line to stock anytime. Its Grin-designed motor, controller, and battery carry a 3-year warranty.
