Your Duo accompanies you daily, but did you know it can become even more efficient? A true engineering marvel, Ritmic's two-seater electric bike hides untapped potential. With its 180 kg load capacity and smart modular design, it’s ready to be customized according to your real needs.
Whether you share your rides with family, carry your daily groceries, or simply want to maximize your passenger's comfort, the right accessories radically transform your riding experience. In this guide, discover the nine essential accessories that will take your Duo from excellent to exceptional.
Passenger comfort accessories: travel together with peace of mind
When sharing your electric bike with two people, the passenger's comfort becomes as important as the rider's.
Passenger backrest: comfort that changes everythingThe passenger backrest adds extra comfort that makes every trip even more enjoyable. It provides welcome lumbar support on daily rides and prevents discomfort after a few kilometers. Its padding prevents tipping backward, especially during acceleration. It installs easily and pairs perfectly with the passenger handles to create a true comfort cocoon. It is the preferred accessory for users who regularly take longer trips with an adult passenger. |

High Duo Saddle: custom ergonomicsThe original Duo saddle is perfect for standard builds, but if you are between 1.70 m and 1.95 m tall, the high saddle transforms your comfort. With its 4 cm extra compared to the standard version, it offers a more upright and natural posture, especially appreciated on long-distance trips. This accessory proves valuable for couples where the passenger or driver is over 1.70 m tall. Installation remains simple thanks to the detailed instructions provided, and the build quality ensures perfect waterproofing even in the rain. The difference is felt from the first kilometers: less tension in the back, better weight distribution, and a greater sense of stability. |

Safety accessories: ride with peace of mind
Safety is never negotiable, especially when carrying a passenger. The Duo already includes many standard features (turn signals, brake light, powerful headlight), but some accessories enhance your visibility and control.
Passenger handles: safety at your fingertipsThe Duo passenger handles are one of the best investments for your two-seater electric bike. Made of high-quality black aluminum, they blend harmoniously with the bike’s design while offering a solid and reassuring grip point. Their ergonomic design allows for a natural and firm grip, which makes all the difference in tight turns or emergency braking. Your passenger immediately feels more confident, improving the bike’s overall balance. Installation takes only a few minutes and requires no special technical skills. |
 |
Mirrors: eyes in the backIn dense urban environments, rear visibility becomes crucial. The Espion Z56 mirrors easily mount on the Duo’s handlebars and offer an optimal field of vision without being bulky. Their compact design preserves the electric bike’s maneuverability while allowing you to anticipate overtaking and change direction safely. With a passenger in the back, your natural blind spot widens. These mirrors compensate for this drawback and give you a complete view of your surroundings. For daily city rides, they quickly become a safety reflex you can’t do without. |

Storage solutions: carry everything you need
The versatility of the Duo two-seater electric bike reaches its peak when you take advantage of its storage potential. With a load capacity of 180 kg and its integrated MIK system, it can accommodate an impressive variety of accessories without compromising its legendary handling.
Front and rear MIK platforms: the base to customize your bike according to your daily needsThe MIK front platform and the MIK rear platform form the fundamental element of your modular storage system. Compatible with all MIK accessories, it transforms your rack into a true universal interface. Its quick and secure attachment system allows you to switch accessories according to your current needs. One day you place a box for your groceries, the next a child seat to take your little one to school. This smart modularity makes all the difference in the daily use of a two-seater electric bike. The platform supports heavy loads while maintaining the Duo's exemplary stability, even when fully loaded. |
Large front basket: the capacity championThe large front basket is the preferred storage solution for Duo users. This matte black aluminum basket measuring 35 x 35 x 20 cm supports up to 20 kg of load. Its generous dimensions easily accommodate your weekly groceries, children's school bags, or all the gear needed for a family picnic. Its aluminum structure guarantees unbeatable durability while keeping the weight low. Installation is easy on the front platform, and its sleek design perfectly matches the electric bike's aesthetics. Practical for everyday use, it turns every trip into an opportunity to carry your belongings efficiently. |
 |
Soft mesh central basket: everyday flexibilityThe soft mesh central basket offers a complementary alternative. Its main advantage lies in its flexible and stretchable side walls that adapt to the volume of the items carried.
Perfect for daily trips, it allows you to easily carry a lock and your essentials like your handbag, a cap, a rain jacket, or your sunglasses. |
 |
Basil MIK boxes: versatility in two sizesThe MIK system opens the door to a whole range of compatible accessories, including Basil MIK boxes. Available in two sizes, these boxes attach and detach in seconds without tools.
The S version is perfect for light errands or personal items, while the L size can accommodate larger loads. Their sturdy design supports heavy weights while remaining easily removable for multimodal use. You can shop by bike, detach the box, and head home without any hassle. |
 |
2-in-1 backpack bag: the multimodal solution without compromising on styleFor commuting or trips requiring a transfer on public transport, the backpack bag is the ideal compromise. This dual use offers remarkable flexibility: mounted on the electric bike during your ride, it instantly transforms into a comfortable backpack once you arrive at your destination. The minimalist design of this backpack makes it a true everyday bag, with its bike bag function remaining discreet. Its design, made for urban cyclists, ensures a secure attachment that doesn’t move, even on rough roads. The inner compartments effectively protect a laptop and your important documents. For professionals who alternate between biking and other transport modes, it eliminates the need to juggle multiple bags. |

How to choose your accessories based on your needs?
Each Duo user has specific needs. Here’s how to build your ideal setup according to your usage profile.
For commuting
Opt for the backpack bag for its versatility and the large front basket to carry your daily belongings. The mirrors perfectly complement this setup for navigating calmly in morning urban traffic. This combination offers an excellent balance between practicality and safety without overloading your two-seater electric bike.
For families with children
The passenger kit (backrest, handles, and footrests) becomes a priority to ensure your child's comfort and safety. Add a standard or MIK rear platform that will allow you to install an approved child seat when needed. The Basil MIK box in size L completes the set to carry a schoolbag, snack, and sports equipment.
For errands and outings
The large front basket combined with the soft central basket offers storage capacity for your weekly shopping. The rear MIK platform with a large Basil box multiplies your transport options. This setup turns your Duo into a genuine, credible alternative to the car for family shopping.
For maximum comfort
Invest in the high saddle if your size justifies it, then add the passenger backrest and handles. This winning trio guarantees your passenger comfort comparable to yours. On long-distance trips or weekend outings, this setup makes all the difference and makes every kilometer more enjoyable.
