Lightweight down‑country e‑MTB for real trail riding
The Forestal e‑Cygnus is a 29” pedal‑assist bike built around a full carbon Alpha Box frame, Twin Levity rear suspension and the latest Bosch Performance Line SX drive unit. It combines cross‑country efficiency with genuine trail capability, so you can climb quickly, cover distance and still have fun when the trail points down.
Key highlights
- 29” carbon down‑country chassis with 120 mm rear travel and 120–130 mm front travel (build‑dependent)
- Bosch Performance Line SX motor (250 W / 55 Nm) with lightweight 400 Wh CompactTube 400 battery
- Optional PowerMore 250 Wh range extender for extra capacity on long rides
- Forestal Twin Levity suspension kinematics for efficient pedalling and confident descending
- Integrated Smart Dashboard 2.0 touch display with navigation, ride data and wireless connectivity
- Clean cockpit with Oxydon carbon integrated handlebar and 60 mm stem
Frame & geometry
The Alpha Box carbon frame is designed specifically for the e‑Cygnus platform. The down‑country geometry uses a 67° head angle for a stable, confident feel on descents while keeping steering sharp and responsive on tight singletrack. Revised sizing and longer dropper compatibility give you more room to move on the bike.
- Alpha Box full‑carbon chassis
- Twin Levity linkage with carbon shock extension
- Head angle: 67°
- Wheel size: 29”
- Travel: 120 mm rear / 120–130 mm front (depending on build kit)

Size recommendations (guideline): S/M 160–177 cm, L 177–187 cm, XL 187 cm+.
Suspension – Twin Levity
Forestal’s Twin Levity system uses a single pivot with rocker and connecting link to deliver a sensitive initial stroke, strong mid‑stroke support and a calm, controlled feel when the trail gets rough. The layout keeps hardware stress low and maintenance straightforward while still giving you plenty of adjustment to tune the shock.
- Single‑pivot, linkage‑driven suspension design
- Carbon fibre shock extension for improved stiffness and lower weight
- Halo build: 130 mm fork / 120 mm rear travel
- Diode build: 120 mm fork / 120 mm rear travel
Bosch Performance Line SX drive unit
The e‑Cygnus uses Bosch’s lightweight Performance Line SX motor. It’s compact and neatly integrated into the Alpha Box frame, delivering support that feels natural rather than overpowering.
- Output: 250 W / 55 Nm
- Approx. motor weight: 2.0 kg
- 160 mm Q‑factor for a narrow, natural pedalling stance
- Very low drag when pedalling above the assist limit or with the system switched off
