Sunday Primer Park 20" BMX Bike Description:
The Sunday Primer Park BMX Bike is designed for all the park riders ready to stomp some 360 double tailwhips and flip whips! Okay, so given that this bike falls closer to the entry-level end of the Sunday lineup, that may be a bit more than this bike was designed for. It is, however, based around modern, pro-level geometry and comes with a full Odyssey Gyro kit, which is typically geared towards skatepark riders. The gyro 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!). Although aimed more towards beginner riders, this bike still offers chromoly 3-piece cranks, sealed bottom bracket bearings, a sealed cassette rear hub, and equipped with several Odyssey components.
Note: This is the 20.5" toptube version of the Primer model.
