Ideal for families who want a discreet, lightweight way to help a child up climbs on paths while keeping the rest of the ride independent.
The ZEFAL Bike Taxi is a lightweight, compact way to extend family rides when a climb becomes too demanding. At just 140 g, it stays under the towing bike’s saddle and is ready when needed, while the 2 m self-retracting rope keeps the bikes separated without leaving loose cable dragging between them.
Installation is tool-free and designed for all standard saddle rails. When both bikes are stationary, the loop attaches between or beneath the two clamping screws on the towed bike’s Aheadset stem; once the climb is complete, it can be released and the rope winds back into its housing. Real-world use shows that children can learn to attach and detach the loop themselves, although the initial saddle fitting can take a little care.
This is a practical choice for family paths and gentler off-road rides, particularly when the towing rider is using an e-bike. The 95 kg maximum combined load and 10 km/h maximum speed are important limits, and the rope must be disconnected before descending. Set off smoothly, keep the rope taut and avoid tight turns for a controlled, confidence-building tow.
The Bike Taxi is intended for adult-supervised use on paths only, helping a child aged five or over through climbs while they continue riding independently on flats and descents. It is a tidy, reusable alternative to carrying a tired bike or cutting a promising family route short.
