A new electric bicycle, the Mapfour Roam, has been added to a comparison that now includes 72 models. Priced at 2,599 euros, the Mapfour Roam is positioned as a competitor to the Decathlon Rockrider e-ST 900, which costs 2,099 euros. The Roam is designed to offer a balance between a comfortable trekking bike and an electric-assisted bicycle that can handle off-road conditions. It includes two suspensions, wide tires, and a Mivice X700 motor that delivers 100 Nm of torque—enough power to ride on roads, trails, and paths with ease. The Roam features a five-speed Shimano Nexus transmission paired with a Michelin belt drive, which is known for its smooth operation and durability. This combination is ideal for a bicycle that is expected to cover long distances. However, the Roam's versatility comes with a trade-off: its 34 kg weight makes it easy to handle when using the motor, but it can be cumbersome to move manually or ride without assistance. Despite its weight, the Mapfour Roam is seen as a solid choice for riders looking for a comfortable and powerful electric bicycle that can transition from city streets to off-road trails. In contrast, the Decathlon Rockrider e-ST 900 is described as a well-balanced electric mountain bike with consistent components. It features a central Brose motor that provides sufficient power and enjoyment, making it suitable for both casual rides and more challenging off-road terrain. The Rockrider e-ST 900 is particularly appealing to those who want to keep up with more experienced mountain bikers.
