Big wheels = big smiles. That is why we decided to offer the benefits of quick 29“ bikes to children and shorter bikers. Thunder 29 HD LTD is the top bike for young riders who want to speed on the trail and uphill. New Junior Trail Advance geometry helps with perfect controllability on singletrack and speed on XC trails. We have chosen easily controllable and lightweight components for the young bikers, so that they could control the bike perfectly. Shimano Deore 1x11 set provides 30x11-51 gear, light suspension fork Suntour with 80 mm travel, and ONE1 carbon seat post offers maximum comfort and control.

2021 NOTE: Due to the pandemic and difficulties in the delivery chain arising worldwide & extreme demand for our bikes at the same time, we reserve the right to replace some parts with those at the same level of performance (e.g. different brand, the same level of parts) to keep the overall quality of our bicycles. We’re sorry about that. At the end of the day, riding a bike is the best way of #staypositive ever, no matter what brand your handlebar or any other part is!
