The task was clear: build the lightest junior 29“ for good money. And it turned out well. We complemented the lightweight frame with the custom made alloy fork, we even lightened the crankset and brakes and equipped the bike with ONE1 carbon seat post. Shimano Deore 1x11 set provides the gear shifting. The bike geometry was chosen for maximum control off-road, speed on-road, and gravel. Thunder 29 VB is also suitable for shorter adult riders who look for an easy and lightweight 29“ bike.

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!
