Skip the coaster brake and get right to it with a handbrake/cassette hub
The "HB" in the product name is short for "handbrake". It's very standard, that smaller BMX bikes come with a coaster brake instead of a handbrake, but that is not the case here.
The guys at Stolen decided to throw a fully-functional handbrake on this 12" model, and leave out the coaster brake to get it right in the first place.
Built for the smallest riders around
The 12" Agent is the smallest of its kind. It's built from strong parts and is meant for 3-5-year-old kids to ride.
