Technological benefits

Montmartre

The Montmartre city e-bike embodies the perfect balance between performance, technology, and elegance in your daily commutes. Even without e-support, it’s a highly efficient bike, light and effortless. The discreet X30 motor is both light in weight and friction-free. Use e-support for that extra boost to climb a hill, maintain speed in city traffic, or simply turn your city ride into a fluid and enjoyable experience.

Mahle X30

We fitted our Montmartre city e-bike with the 250Wh Mahle X30 motor with its 45Nm of torque. This brushless, ergo friction-free hub motor is synonymous with low energy consumption making cycling even without e-support a similar experience to that of a traditional bike. Heavier bikes require more power and far more torque. But if you do need more range, the option of a second battery is a real solution.

Cutting-edge technology

ANT+ connectivity for direct links for example to your GPS via a dedicated application that adapts the level of e-assist as per the difficulty of the terrain, your heart rate and the power you develop.

Hand painted in our own workshops

All Origine's forks and framesets are painted at our proprietary factory in the north of France. We have chosen to use only automotive grade water-soluble paints. The impact and abrasion resistance is far superior to that of frames painted in Asia and the ecological impact is greatly reduced. Like all Origine products, the Help Road frame has a lifetime warranty and is entirely customisable using our online configurator allowing you to factor in your style, expectations and budget.
