The UP30e has an high performance pedal motor with provenance from the BROSE factory. Its qualities are unanimously recognised and its silence in motion is exemplary.


German Quality

The large industrial company Brose has been developing electric motors for bikes for many years. Today it is a major player in this sector and their motor BROSE DRIVE was created out of rigorous development of precision equipment. One of the principal qualities it offers is one of the most advanced couples on the market,  a criterion which is very important for cargo bikes.

The motor is very quiet, thanks to the carbon drive belt, delivering powerful assistance in proportion to the effort of the cyclist, up to 25 km/h and without resistance. A new firmware was developed especially for the G4 for the use of cargo bikes.

The compact design of the BROSE motor allows optimal integration on the frame and significant weight gain. The motor is assembled entirely in the BROSE factories in Berlin, proudly stamped MADE IN GERMANY.

The battery uses the new technology Li-ion Graphene for an increased energy capacity. The G4 is made to house an extra battery allowing it to reach a total capacity of 1270 watts. (2 X 635 Wh). This equipment makes the G4 the cargo-bike the most autonomy on the market.

We have created or selected an ensemble of equipment to respond to a multitude of needs.
Each user can configure their DOUZE precisely to optimise their ride and pleasure.


The soft bag is a waterproof, lightweight and resistant pannier. Lined on both side to retain its curved shape, it is resistant to weather and protects your children comfortably inside. The bag attaches quickly thanks to the Velcro that is sewn on. Solidly fixed on the BOTTOM AND TOP SIDE TUBES you will never have to re-tighten or adjust it. There is a pocket on the rear section of the bag for you to protect your telephone, papers etc.

The top cover closes the box entirely, with six adjustable clips fixed on the bottom part of the bike. The straps on the upper part can allow you to strap on an extra bag or box if you need.


Classic aluminium box

The ALUBOX aluminium box is simple and resistant. Available for all three lengths of frame, it’s the best way to start any activity.

Alubox 600x400x600 – 140 L
Alubox 600x600x610 – 156 L
Alubox 800x600x610 – 216 L

 KEP 600 or 800 aluminium box

The fully welded aluminium KEP box takes the form of the frame for enhanced aesthetics and load optimisation. Thanks to the offset of the opening at the front end, you can use this box with 60 or 90mm brackets to maintain the ‘sport’ position. The large load volumes, 200L for a 600 frame and 250L for an 800 frame, allow you to carry a load which is fully protected from the elements.


RHINO Aluminium Box

The Rhino Box is made in Berlin by a passionate company.

BicyLift® Trailer


The Bicylift trailer is the perfect combination of a pallet truck and a bike trailer, for handling and transporting loads packed in European pallets or containers. Far from a simple cart, this auto-brake trailer increases the capacity of your bike and becomes a true logistics tool. The patented material is manufactured in France by the company FlexiModal, with whom we have developed a specific hitch for our frames, in turn guaranteeing perfect compatibility.


Depending on your needs and the terrain on which you will take your DOUZE, we offer you different methods of transmission. From a simple SRAM derailleur, to the ultimate combination of a PINION ® 12-speed chain and the GATES CARBON DRIVE belt you will find the solution.


NUVINCI N380, vitesse en continu

The  Nuvinci N380 shifter is a revolution. Where most other hubs generally require the rider to reduce the pace of pedalling for a short time to engage the speed, this hub will free you from this inconvenience.


1x9 Speed SRAM Derailleur

The SRAM X serie 9V rear derailleur is a model which offers excellent performance and looks superb. Build on an ultra-light chassis with an aluminium clevis, this 9 speed derailleur uses the famous 1:1 technology which provides simple adjustment and reliability. It also features the Direct Route concept, which assures direct and rapid mechanism activation, for quick and precise gear changes and reduced friction.


Composed of two metal gears and a high resistance, carbon fibre belt, Gates Carbon Drive is a low maintenance chain replacement technology from Gates Corp., the world leader in automotive and industrial belts. Clean, quiet, lightweight and solid, Carbon Drive doesn’t require any grease lubricant, weights less than a chain and does not stretch. Due to its low maintenance and its cleanliness, Carbon Drive is a technology which makes the use of cargo-bikes much simpler and smoother.





Hydraulic disk-brakes are a must-have on a cargo bike. The Tektro GEMINI offers you a progressive and powerful braking system. Depending on your needs, if you wish for a more aggressive braking system, you could also choose the MAGURA range brakes with 180mm discs.



The EASY UP steering column allows you to change the height of your handlebars without tools. You can then adjust your riding position at any moment in just seconds.

Finally to optimise your position on your DOUZE, you can equally choose the shape of the hanger (flat for a sport / road position, or Moustache to have the view straight on), the length of the stem (10, 60 or 90mm) then the shape of the handles (right or ergonomic).


Sport or Comfort

The double height seat post allows rapid adjustment without tools. Thanks to the rapid tightening, each user can find the best height to pedal comfortably. For the comfort and style you can choose from between different types of saddles, including the leather saddles created by the famous English brand BROOKS.



The from and rear lights are always available to be seen in any circumstances. The lights are connected to the battery and can be turned on with the RC3 controller.


Every model in the DOUZE range integrates two major innovations in the world of cargo-bikes.

Rapid separation

DOUZE Cycles is the only cargo-bike manufacturer to propose such an innovative system.

Rapid separation allows the front and rear frame to part without difficulty in less than two minutes.

You then have the possibility to easily take your DOUZE anywhere in the boot of your car or on a bike rack.

This exclusive functionality, you have the possibility to travel on the train with your DOUZE! You can also park it easily in a small or narrow room with the cargo-bike in two halves.


The quick separation is the feature that vastly separates our bikes from those with a one-piece frame!

2*2 Cable Steering

This exclusive system of cable steering offers exceptional maneouverability!

The angle of rotation of the fork rotates up to  75º to the right and left. At a low speed, you an maneuver freely and do a u-turn in tight spaces. However, the steering stays tight and strong when the speed accelerates. The symmetry maintains the course in case of intense braking. Compared to a classic steering system, the handling of DOUZE are simple and intuitive.

Whether you’re using a 400, 600 or 800 frame, you’ll be surprised by the impressive handling even at a full load.
