Bike43 Short - Bosch Performance Line (75Nm)

The Bike43 Short is a Belgian cargo bike of a unique kind. Designed in Brussels, it positions the load as close as possible to the rear axle — which gives it a riding behaviour similar to an ordinary bike, unlike front-box cargo bikes that radically change the steering. The Bosch Performance Line Gen5 75 Nm 600W Smart System provides a calibrated progressive assistance for heavy loads, with the Bosch PowerTube 540 Wh housed in the frame. The Bosch Purion 200 Smart System controls the whole system, with access to the anti-theft functions of the Smart System: eLock (automatic unlocking via the Bosch Flow app), motion alarm and battery lock. The Bike43 Short accommodates up to 2 children (PTAC 170 kg) and is convertible to a Mid model (+15 cm) without changing the frame.

On the mechanical side, the Bike43 Short opts for long-term robustness: the transmission is a Shimano Nexus Inter-5E, 5-speed internal hub — no exposed derailleur, no specific maintenance, no risk of derailment under load. The SR Suntour Mobie 34 CGO 80mm fork absorbs irregularities, the Shimano BR-MT200 hydraulic brakes (discs 180mm front and rear) ensure stopping power. The CST Brooklyn Pro 20×2.44" tyres are a cargo reference for puncture resistance. Three Bike43 innovations complete the picture: the swivel bench (opens like a car door to install children without acrobatics), the patented Magic Footbox (first child's feet protected under the saddle, bike shortened by 15 cm), and the Up & Down stem (handlebar height adjustable without tools for riders sharing the bike).

In Brussels, the Bike43 Short meets a practical need: transporting 1 to 2 children in a city where narrow cellars, apartment corridors, and the alleys of the Pentagon make longtails difficult to manoeuvre. Its compactness (Short or Mid depending on the family's needs) is designed for everyday life in a dense city. The internal gear transmission is a real advantage for families who do not want to deal with derailleur adjustments — it handles heavy starts and wet winters without flinching. The frame scalability (convertible Mid) means that the bike grows with the family without changing vehicles.
