NS Bikes Eccentric Mini Pro 2025 Junior Bike

When developing the nerd mini we found that 27.5” wheels work great for riders who are around 145-155cm tall and this is the wheel size that we chose for this scaled down eccentric. Just like the ‘grown up’ eccentric bikes, the mini is a modern, tough trailbike with radical geometry. It’s an efficient climber and is super stable on the downhills. It’s built around a tough alloy frame with a low bb, low standover, slack head angle and steep seat tube angle. Thanks to the properly designed geometry small riders will feel equally comfortable on climbs and descents. The key to success on the downhills is the slack head angle and big wheels - this will keep the bike stable even on the roughest trails. It’s worth mentioning that the eccentric mini is one of the very few bikes on big 27.5” wheels for kids.
