G4, the universal cargo bike
The G4 possesses all of the assets to become your favourite vehicle and is a true alternative to a car. The G4 has a large storage area of 270 litres which can be locked to effectively secure its contents. Thanks to the innovative lid and the partial opening, there is no need to choose between transporting the children and having a completely closed compartment: both are possible in one trip.
Motorisation premium & grande autonomie
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.
Secure and comfortable steering
2*2 cable steering
The Douze G4 benefits from the exclusive system of cable steering created by DOUZE Cycles in 2012. This technology is proven to increase the handling even in tight spaces, and allows it to feel as if you were riding a traditional bike.
Cable steering for exceptional manouverability!
The angle of rotation of the fork rotates up to 75º to the right and left. At a low speed, you an manoeuvre 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.
No matter where they go, the new suspension fork offers great riding comfort, cushioning and unmatched handling for more safety. It is specially sized for the use on a cargo bike, and integrates the pulley of our cable steering. Experienced riders will appreciate that it is adjustable and lockable if necessary.
