A well spec'd hardtail bike at a fantastic price point offering both affordability and Haibike's German engineering. The HardNine 4 is great for trail riding and forest paths.

Superb bike and opens up cycling again that is more than pottering around the roads to older cyclists like me who don't want to bother with straining up hills or having to avoid tracks and bridleways.
