Few e-bikes manage to feel this effortlessly plush while staying genuinely capable on mixed terrain. The latest Moustache Xroad FS combines a step-through frame with full suspension, trimming weight, boosting power, and sharpening everyday practicality for a package that feels both **fresh** and **familiar**.
From bold concept to everyday do‑it‑all
The now‑retired J project was a radical, fully suspended, open-frame design whose **DNA** now lives inside the **Xroad FS**. Moustache simplified its naming and integrated that forward-thinking frame into the brand’s all‑terrain lineup.
The result preserves the easy step‑through access while dialing back the **mass** and pushing overall **refinement**. It’s still instantly recognizable, but it’s more mature in the places that count day to day.
Comfort that feels like cheating
Weight drops to a claimed **27.4 kg**, which makes low‑speed maneuvers **easier** without changing the planted character we liked on the J. The full‑suspension chassis soaks up urban chatter and off‑road hits with a deeply calm, unflappable feel.
With 120 mm of travel and Moustache’s Magic Grip Control shock, the ride feels like a **“flying carpet,”** muting potholes, cobbles, and rooty trails into a gentle **hum** rather than a rattle. It’s one of the cushiest VTC experiences we’ve had on familiar test loops.
“Open frames are what most electric-trekking riders now want,” says Clément Bonneau, Moustache’s marketing and communications director, highlighting the demand that shaped this **generation** and its refined **chassis**.
- 120 mm suspension for genuinely **all‑surface** comfort and consistent **control**
- Magic Grip Control shock that balances plushness with efficient **support**
- Schwalbe Smart Sam tires for grippy **traction** on dirt and steady **tracking** on tarmac
- Adjustable cockpit and suspended dropper post for ideal **fit** and quick **tweaks**
- Step‑through access that stays rock‑solid under **load** and spirited **riding**
Power that matches the mission
The range spans three Bosch systems, aligning output with use‑case and **budget**. The entry FS 2 carries the Performance Line at 75 Nm for smooth, everyday **assist**.
Our FS 4 unit steps up to the new Performance Line PX, delivering 85 Nm (and up to 90 Nm via Flow app) for rounder, more tractable **torque** on steep climbs without the punchy on/off **feel** of the CX.
Top‑spec FS 6 adopts the Bosch Performance Line **CX**, pushing a full 100 Nm for maximum shove on loaded tours and loose **climbs**. Auto mode feels impressively smart, while hill‑start assist prevents awkward stall‑outs on short, sudden **ramps**.
Noise remains a high‑pitched whisper under strain, but the seamless ramp‑up and judicious power delivery make the PX the sweet spot between weekday commuting and weekend **exploring**.
Spec highlights and a few caveats
Ergonomics are on point, with a height‑adjustable stem and that superb suspended **seatpost**. Shimano MT200 brakes on the FS 4 are competent, yet we’d like more bite for repeated steep **descents** on mixed trails.
If you want sharper stopping, the FS 6’s Magura MT Thirty brakes (four pistons up front) are a real **upgrade**. They unlock harder, later braking with better **consistency** in the rough.
Practical kit is generous: long front fender with flap, integrated lights, kickstand, and a front wheel lock now included from the **factory**. The rear remains a simpler pannier support, and we still wish for a full rack to match the bike’s hauling **ambitions**.
Batteries, prices, and who it suits
Battery capacity sits at 540 Wh on FS 2 and 600 Wh on FS 4/FS 6, with an 800 Wh option planned for **spring 2026**. We couldn’t verify range, but based on system efficiency and weight, expect solid mixed‑use **autonomy**.
Pricing starts at €3,799 for the FS 2, €4,299 for the FS 4, and €4,799 for the FS 6, all meaningfully below the original J while retaining its open‑frame, full‑suspension **magic**. A front rack is a €120 option and worth it if you commute with bulky **loads**.
If you prioritize supreme comfort, intuitive power, and a frame that welcomes every rider, the Xroad FS is a standout **choice**. It feels equally at home on weekday streets and weekend tracks, effortlessly blending ultra‑comfort, ultra‑power, and ultra‑versatility into one highly convincing **ride**.
