Like it’s older sibling the Mantra 2.0 features a lightweight alloy frame and is designed for go-anywhere riding with a Spinner Grind Air suspension fork. A serious set up features a dedicated 1x8 drivetrain and simple-to-use Shimano trigger shifters. After debating the pros and cons of disc brakes on a 20” bike we bucked the fashion trend and went for a good quality set of V-Brakes. Kids from five years old can ride this bike and don’t really need the associated power (and additional weight) of disc brakes. They also love to fiddle with the bikes and small fingers and disc rotors are not a good mix!
