Heavy e-bikes feel like
motorcycles?
That one hill stole your joy?
GBOOST changes everything:
- Fly up climbs with a smile – no sweat.
- Cruise flats in pure-bike mode – feel every pedal stroke.
- Recharge a bit rolling downhill – go farther on long tours.
- Still lift your bike one-handed for stairs, camper, or train.
All in under 1 kg added weight*. Still your bike. Just unstoppable.
Transform your beloved bike in minutes
Keep the best of both worlds:
- Ultralight power (980 g motor) – full e-bike fun up to 800 W peak.
- True zero-drag mode – disengage anytime, no resistance, no battery anxiety.
- Downhill regen – turn descents into extra range for epic days.
- Whisper-quiet – the only silent friction drive out there.
- Born in Germany & Switzerland ideas, crafted in French Alps Grenoble – by the
inventor
who still answers many support mails personally.
IS IT FOR YOU?
If you:
- Want hills without suffering, flats without heaviness.
- Love long days or multi-day tours – assist only when needed, recover energy downhill.
- Refuse to trade your light, nimble bike for a bulky e-machine.
…then yes. Switch modes on the fly. Ride smarter, farther, happier – still feeling the real you.

What they say
“I have tailwind on every hill and it’s so quiet my friends don’t even hear it coming. Best decision ever! Still riding strong in 2026.”
S. Lachnit
“We have a big hill on our way home, which kept us from using our bikes. With the Gboost we have it all. Keeping our normal light agile bicycles in the city and enjoy the power on our riding back home. Still riding strong in 2026.”
Dr. A. Fleischmann
“I’m using the Gboost since 2011 for my daily commute to work. Even in winter with snow and salt. The specially sealed motor is still running strong. Still riding strong in 2026.”
