Onza Mini Master 18-Inch Trials Bike
The Onza Mini Master is Onza's smallest trials bike with an 18-inch wheel and XS frame, aimed at anyone between 5-9 years old or anyone older who just likes to fool around.
It has a light high-grade 7005 Alloy frame for low weight and high stiffness and compliance, ensuring younger riders get the most out of it. High volume tacky tyres are able to cling to many surfaces and obstacles, and the v-brakes are super sharp and responsive. The cassette also has an excellent rate of engagement which ensures that minimal energy is spent unnecessarily.
