Sunday Primer 18" BMX Bike-Gloss Fire Engine Red

The Sunday Primer 18" BMX Bike-Gloss Fire Engine Red is a smart step up for young riders ready to push their limits. Sized just right between a 16" and a full 20", it features pro-style geometry, lighter wheels, and a shorter chainstay for better control and quicker progression. With dependable parts like a fully sealed 9T cassette hub, Odyssey Springfield Brakes, and Sunday’s own Freeze stem, this bike is built to handle serious sessions.

NOTE: As with any complete bike, J&R Bicycles recommends that you have a professional bicycle store build your bike. Bikes ordered through mail-order come partially assembled and need to be inspected and assembled by a bicycle mechanic. Failure to do so may void the manufacturer's warranty. Manufacturers’ warranties differ for every brand. You can check the brand's website for warranty information.
