Ridgeback Arcus 1 Open Frame
Description
The Ridgeback Arcus 1 Open Frame E-Bike is built for riders who value versatility, comfort, and dependable performance on a variety of terrains. Whether you’re commuting to work, exploring country lanes, or tackling gravel tracks, this e-bike offers the power and stability to make every journey enjoyable.
At its heart is the Sportdrive M155 motor, delivering 250 watts of pedal assist and up to 40Nm of torque. This system provides seamless power when you need it most—climbing hills, accelerating from a stop, or maintaining speed on long rides. With pedal assistance up to 25km/h, you can cover more ground with less effort while still enjoying the feel of cycling.
Comfort is a priority with the Arcus 1. A 63mm suspension fork works in harmony with 45mm wide tyres to absorb shocks and smooth out rough terrain. This combination ensures a stable, cushioned ride, making it perfect for mixed-surface use, from tarmac roads to gravel paths and towpaths.
Safety and control are handled by hydraulic disc brakes, providing reliable stopping power in all weather conditions. Whether you’re descending a steep hill or navigating busy urban streets, these brakes deliver the confidence you need.
Weighing just 29.2kg, the Arcus 1 strikes a balance between durability and ease of handling. Its open frame design not only looks stylish but also improves mounting and dismounting comfort, making it ideal for a wide range of riders.
The bike’s alloy frame offers a perfect mix of strength and lightness, while its external battery integration keeps maintenance simple. From daily commutes to weekend adventures, the Ridgeback Arcus 1 is built to be a reliable partner.
If you’re looking for an e-bike that blends performance, comfort, and style while handling both road and gravel equally well, the Ridgeback Arcus 1 Open Frame E-Bike is an excellent choice.
