Primer 18" 2020 BMX Stunt Bike

Explore your first tricks with the 18" Primer

The Primer 18" by Sunday is a fun and easy-to-ride freestyle BMX for kids and young riders who aren't quite ready for a 20" yet. Every part on the Primer 18" stays true to BMX geometry, meaning the transition to a fully sized setup will be much easier than it would be coming from a regular kid's bicycle.

For this 2020 model, the guys at Sunday decided to throw a fully sealed cassette hub into the recipe, providing a great roll and minimum need for maintenance.

Technical features

• Easy maintainable 3-piece cranks with shortened 140mm arms for enhanced pedalling
• Integrated 1-1/8" headset for smooth handling and steering
• 19mm mid bottom bracket with sealed bearings
• Grippy Sunday Current tyres in a semi-fat 2.2" design for maximum traction
• Aftermarket Sunday Sabertooth V2 sprocket - same as on many high-end completes
• Classic 2-piece bars in a scaled-down 7.65" tall and 25.5" wide version
• Fully sealed cassette hub with 14mm axles and a 9T driver
• Sized to be as easy as possible for kids and younger riders to manoeuvre and control
