Smart 2-in-1 Child Bike Trailer BT511

The Smart 2-in-1 Child Bike Trailer BT511 is a practical 2-in-1 solution that can be used both as a bicycle trailer and as a standalone pram. The model is designed for transporting one or two children and can easily be adapted to how the family wants to travel. When used behind the bicycle, the tow bar connects to the rear axle of the bike, while the removable front wheel and handlebar are used when the model is configured as a pram.

Inside there is a five-point harness that keeps the child securely in place during transport. When transporting one child, the child should be seated in the centre, though the trailer also has room for two children. The included cover has a PVC rain shield that helps protect passengers from rain and flying dirt. The rain shield can be rolled up for better ventilation, and the mesh panel at the front allows air circulation on warmer days.

The foldable construction makes the BT511 easier to transport and store when not in use. The rear wheels can be removed with a quick-release system, and the front wheel is fitted when the trailer is to be used as a pram. The parking brake is intended to be used when the trailer is stationary in pram mode. The safety flag increases visibility when the trailer is used behind a bicycle. According to the manual, the maximum load is 40 kg and the maximum speed in bicycle trailer mode is 16 km/h.

Order the Sepnine BT511 from Wheelyshop if you are looking for a flexible child bicycle trailer that combines cycling transport and pram function in one product.

Important: Always check usage and follow the product's safety instructions.

Electric scooters (e-scooters)
Rules for e-scooters are not fully harmonised across the EU – each member state sets its own requirements. In most EU countries, e-scooters are limited to a top speed of 20–25 km/h for use on public roads, and some countries also require type approval, insurance or a minimum age. Models that exceed the national limits – for example with higher top speeds or stronger motors – may generally only be used on private property. Always check the current rules with the national transport authority in your country before riding on public roads.

Electric bikes (pedelecs)
Across the EU, an electric bike is treated as a regular bicycle if the motor has a maximum continuous rated power of 250 W, only assists while you pedal, and cuts out at 25 km/h (EU Regulation 168/2013 and EN 15194). Such pedelecs require no registration, licence or insurance. The motor may temporarily deliver a higher peak output, as long as the continuous rated power does not exceed 250 W.

Faster or more powerful models (such as speed pedelecs with assistance up to 45 km/h) are classified as mopeds (category L1e-B) and are subject to type approval, registration, insurance, helmet and licence requirements that vary by country. Models that do not meet these requirements may only be used on private property.

We strongly recommend wearing a helmet, even where it is not mandatory.
