Rider Profile

Best For	Best suited to riders with genuine trials skill or those actively learning technical balance and clutch control, as this is a specialist competition tool rather than a beginner road bike.
Purpose	Built purely for technical trials competition, tackling rocks, steps, and slow-speed obstacles rather than covering distance or carrying passengers.
Rider Fit	Its extremely light dry weight and tall, slim chassis reward standing, active riding and good core balance more than raw strength.
Character	A featherweight, high-clearance single with minimal power but razor-sharp agility, designed to be flicked, hopped, and balanced over obstacles.
Not Ideal For	Not suitable for riders wanting highway speed, long-distance comfort, or a bike capable of carrying a passenger.
