A closer look at the model

The bike in detail.

FX 1 is a versatile and refined hybrid bike designed for everyday outputs, fitness and home-work travel. The lightweight chassis and Shimano transmission at 8 speed offer a wide range of ratios and easy to use, while mechanical disc brakes ensure reliable braking power. Thanks to the attacks for luggage carriers and accessories, it is very easy to adapt according to the schedule of the day.

Fast and efficient - The active geometry allows you a more comfortable and upright position to travel further, having more fun and getting less tired.

Questions before you ride?

How do I check availability in my size?
The size table distinguishes in-stock items, online orders and sold-out items. For sizes available on request, use the contacts in that row to confirm availability and lead times with our team. Only variants available for online purchase can be added to your basket.
Can I test a bike before deciding?
The Doctorbike Bike Test is available by category, rather than for every individual model. Our team will confirm the category, size and test availability with you.
Can I get help with size and riding position?
Yes. Talk to our team and explore bike fitting with Velosystem® technology, with dedicated measurements and adjustments.
Who should I contact for servicing?
Contact our certified workshop in Magenta. Arrange the work and an appointment with us: our service continues after purchase.
