E-Mountain bike manufacturer Moustache enters the fray, rekindling interest in step-through frame designs of yesteryear with a distinctive unified rear triangle suspension (URT) model, known as the J. Off. Historically criticized for poor suspension performance and altered geometry when weighing the whole rider on the swingarm, Moustache claims to have found a niche for the design, particularly for recreational riders. Proudly asserting the J. Off's remarkable rigidity for a responsive ride, it promises an authentic mountain biking experience.

Jumping on the Step-Through Frame Trend

Moustache joins Haibike in bringing back the step-through frame design to the forefront, this time with an enhanced twist - the unified rear triangle suspension (URT). Popular in the late '90s and early '00s, URT aims to reduce pedal-induced bobbing and improve the bike's performance by integrating the whole drivetrain on the swingarm.

Moustache J. Off e-Bike: A mix of '90s elegance and cutting-edge technology.

An Intriguing Mix of the Old and New

The J. Off e-bike combines a fusion of a modern e-mountain bike (e-mtb) and an urban utility bike, with a hint of the classic '90s suspension design. Moustache seems optimistic about the potential for URTs, especially among leisure cyclists. However, the J.Off is marketed as a "real MTB," promising incredible rigidity and responsive handling worthy of its mountain counterparts.

Does the J. Off e-bike's unified rear triangle suspension design live up to its bold claims?

The Key Specs

  • Powered by the Bosch Performance Line motor, which is a recreational-level drive unit with slightly less power and torque than the Performance CX.
  • A 625Wh removable internal battery embedded in the alloy frame.
  • Integrated lights and lock for added convenience.
  • Unique frame design features a clamshell construction using no welds at all. French manufacturing keeps supply chains short and sustainable.
  • The adjustable chainstay length on the swingarm caters to the belt drive and internal gear hub found on the urban model.
  • Fork travel of 130mm, while the URT swingarm delivers 115mm of travel through the Moustache Magic Grip shock.
  • Wheels are 29in front and rear, and the bike offers a comfortable, upright riding position with a massive stack height and a generous max weight capacity of 160kg.

The J. Off's innovative frame and suspension setup sets it apart from other modern e-MTBs in the market.

The Numbers Don't Lie

The bike features an extremely compact 359mm reach and an unusually long 524mm chainstay length across all three frame sizes (compared to most small frame sizes). This unique geometry raises questions about the bike's appropriateness for fast and technical singletrack, as it seems more suitable for leisure cruising or easier off-road trails.

The J. Off's geometry and size may appeal to certain riders seeking a comfortable, stable off-road experience without advanced handling requirements.

Brand Reputation and User Experience

Moustache bikes, including other models like the Samedi series, are praised for their build quality, ride characteristics, and customer support. Reviewers praise the J. Off's ability to smooth out rough terrain, offering a very comfortable ride even on demanding surfaces. Its adaptability across different riding styles and terrains also garners positive feedback.

In summary, the Moustache J. Off's unified rear triangle suspension design offers a smooth, comfortable ride and efficient power transfer, making it well-suited for technical and rough terrain. While it may present challenges in maintenance compared to more conventional e-MTBs, its innovative structure resonates with reviewers for its ride quality and versatility.
