Description

Give your youngest the best start in their BMX racing career by getting a Chase Race Series Mini under them. If your rider is just getting their first serious race bike, then this mini is the perfect sized race bike for them.

Chase know a thing or two about winning and this experience flows all the way down to their smaller bikes, and entry level bikes like the Race Series. With an all aluminium frame and chromoly forks, it's built from the same race winning materials as the bigger bikes in the range and means that it'll handle anything your youngest racer can throw it at.

Add in double-walled alloy rims and this Chase Mini will take on biggest, baddest tracks with ease and when your rider is ready to move up to the next sized bike, the build quality and reputation that the Chase name brings ensures that this race rig will be ready to pass down to the next rider coming up in the family, or passed onto another young shredder.

Available in two contrasting colour schemes, the skittles version will suit your little extrovert, while the quiet achiever will pick the black/grey Chase to let their riding do the talking out on track. Either way, they will love their first race bike.
