Performance and Handling:
The S.170E is engineered for high-speed descents, offering exceptional traction and composure on challenging trails. Its design prioritizes descending performance, making it less suited for long, leisurely rides or flow trail jibbing. The bike’s handling is approachable, inspiring confidence across various skill levels. (ebike-mtb.com)
