Bike info

The Nerd JR is the ultimate kids' mountain bike. With 120mm travel front and rear, 24” wheels, and the option to upgrade to 26”, the nerd will last for years and handle any kind of riding. Lots of effort has gone into dialing this bike - it's not just an afterthought, addition to the range, like many other kid's bikes. We took this project very seriously. Our goal was to make it capable of growing with the child and making it suitable for many different types of mountain bike riding - anything from XC to freeride. One of the key features is the possibility to upgrade the bike to 26” when the time comes. After the wheel swap the bike still retains correct geometry thanks to the set of offset shock bushings that are included. The lowered BB and slacker head angle optimize the handling of the bike for bigger kids (that will most likely will ride faster and more aggressively). Developed and tested by the NS Bikes founder and his son, this is really a dream kids bike.

 

MAIN FEATURES:
Alloy frame with 120mm travel
24” wheels (will accept 26”)
Air shocks front and rear
Hydraulic disc brakes
Shimano Deore 1X drivetrain

The Nerd bikes are all about fun - light, efficient and strong.

 

Kid’s bikes are a top priority for us, and the development of the Nerd JR and Nerd Mini was personally overlooked by our CEO and the NS junior test riders which include his son Max and his friends. The whole team started on the smaller bikes with 24” wheels, then switched to 26” and are now riding the 27.5” bikes. One of the key things we noticed during the process of developing the kid’s bike range was that most young riders are on bikes with wheels that are too small. We all know the benefits of big wheels, don’t we? More stability on downhill sections, more grip, ease of rolling through roots and rocks etc. So why force the young ones to roll on these shopping carts? Well there’s one catch – the geometry of the kids bikes with relatively “bigger” wheels needs to be designed in a different way. The BB and cockpit must be as low as possible. Standover must be taken into account and many other factors must be taken into account otherwise the kids will end up being too far from the ground, with their legs dangling in the air at every stop, and a high front end will make it hard to climb. So, that’s what we did in our kids bike range – we went loooow. But that’s not everything. Other details that include the crank length, saddle shape, resulting riding position have been taken into account and the result is a bike that we feel is one of the most dialed offerings on the market.
