The Sunday Primer Park 20" BMX Bike is a great entry-level BMX bike. The bike is designed with pro-level frame geometry and sealed bearings in the bottom bracket and cassette hub. The Park model includes a detangler kit, which allows you to spin the handle bars around as much as you want without tangling the brake cable. This is perfect for riders looking to learn barspins or tailwhips and still wants to be able to do brake tricks (or just to simply have brakes to stop!). Note: This is the 20.5" toptube version of the Primer model.
