A dream come true

J am not a bike but a brand-new day

J, original design

Emmanuel Antonot

Co-founder of Moustache Bikes

We dreamt of a bike that was more open and comfortable than ever before, a bike that would go further than anything we had made before. A magical bike that would inspire people to take up cycling or rediscover the joy of riding a bike.

We dreamt of making this bike entirely in France, close to home, using a short supply chain, and reviving skills that had been neglected in France for years.

We wanted J to represent a new day for cycling pleasure and a new approach to designing and manufacturing a bike.

However, turning this dream into reality was not easy. Three years of effort from our teams and partners were required. Three years of pushing our boundaries. Three years that gave even more meaning to the Moustache adventure!

The founders of Moustache share this dream with you:


In 2011, the Moustache project started with a blank canvas. For J, we revisited that blank canvas and started from scratch, freeing ourselves from constraints to create our dream bike, our wildest dream!

As soon as it was revealed, J received the Eurobike  Gold Award 2023 in June, a prestigious prize awarded at the world’s largest bicycle trade fair.

We’re very proud of this international recognition, which rewards all our team for their determination, creativity and precision!

Moustache’s R&D and design teams share their challenges:

Made in France

Our teams and partners share the challenges of manufacturing J in France:

more sustainable

Short supply chain

Producing our bikes in France reduces the travel distance of our frames from over 9,300 miles to less than 620 miles – a significant step and great satisfaction for our teams.

Optimised material sourcing

For optimal quality, our foundry partner uses a first-fusion aluminium alloy sourced from French and Italian suppliers. The aluminium is refined directly from ore, without reprocessing various aluminium residues or impurities. All scraps and surplus materials are recycled through remelting.

Solvent-free powder coating

To further reduce our impact, we use solvent-free powder coating for the frame, eliminating the use of solvents and providing enhanced durability for a longer-lasting finish.

Like floating on a cloud

J is ultra-comfortable

It features adjustable full suspension and a comfortable saddle.

The Moustache Magic Grip Control hydro-pneumatic rear shock magically smooths out all obstacles.

Its geometry prioritises comfort, with an ergonomic Moustache handlebar and adjustable stem for a natural, upright position.

Child’s play

J is easy to use

With an open frame that is easy to step over.

Dropper seat post that lowers with a simple press of the thumb, making it easy to put your feet on the ground.

The rear suspension is easy to adjust depending on the user’s weight and there’s an adaptive lever for different loads and terrains.

The intuitive, continuously variable transmission allows for smooth gear changes with a simple twist of the handle (on the ‘Enviolo’ versions).

Like a magic carpet

J is ultra-efficient

The rigid frame and unified swinging arm suspension transfer all the energy to the rear wheel without loss.

Plus, you can go even further by fitting an additional Bosch PowerMore battery.
