A closer look at the model

The bike in detail.

District+ 3 R9 is a traditional city hybrid e-bike perfect for day trips and weekend trips. The Shimano CUES 9 speed transmission allows you to easily tackle both flat and climbing traits, while the Bosch Active Line Plus Smart System engine and the 360Wh removable built-in battery provide all the power you need to pedal in maximum comfort.

A better way to produce aluminum - Starting from 2024, we started replacing traditional aluminium with reduced carbon footprint aluminum, produced with renewable energy. By October 2025, almost all the aluminum bikes produced, including this one, have made the transition, significantly reducing our environmental footprint.

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.
