Why this bike is for you
You are an intermediate rider scaling up to 152 cm – 168 cm (5'0"–5'6") in height and need a more accommodating 20.5" top tube frame.
You want a setup that features fully sealed internal components like the headset and bottom bracket to significantly reduce maintenance.
You are ready to push your boundaries across multi-discipline riding, from local skateparks to hard-packed dirt jump lines.
Why this bike may not be for you
You are a tall, advanced pro rider who requires a 21-inch top tube and a 100% full 4130 Chromoly frame matrix to survive extreme street gaps.
You intend to travel long distances or require front and rear handbrakes, gear ratios, or utility mounts for everyday cross-country trekking.
For safety reasons bikes can not be shipped partially assembled; they must be fully built and inspected by an authorised technician prior to collection or delivery.
