Overview
The Sunday Park Ranger is a bare BMX frame, not a complete bike, built from 4130 chromoly steel with a 20.5 inch top tube for park, transition and street riding. It ships in the Toothpaste green colorway with round Nightshift-style tubes.
This is a frame only purchase, so a fork, wheels, drivetrain and cockpit all have to be sourced separately to build a complete bike. Sunday pairs a steep head tube angle with short chain stays for sharp, quick turning, and combines that with a tall bottom bracket and low standover height for pedal clearance through tricks. Hollow 8mm dropouts with internal chain tensioners and removable brake mounts keep chain tension and brake setup simple to adjust.

- Hollow 8mm dropouts with internal chain tensioners
- Toothpaste green finish with round top and down tubes
Who it's for
Riders who already run their own build kit and want to swap in a lighter, more aggressive chromoly frame for park or street riding. Not for anyone who wants a ready to ride bike straight out of the box.
Strengths and trade-offs
Drawn from this product's published specifications.
- 4130 chromoly steel for durability
- Removable brake mounts simplify setup changes
- Internal chain tensioners keep dropouts clean
- Frame only, no fork or components included
- No rating or review data available yet
Performance notes
The steep head tube angle and short chain stays quicken the steering and make tight, technical turns easier to hold. A tall bottom bracket combined with a low standover height gives extra pedal clearance during tricks without changing the seated riding position much. The hollow 8mm dropouts with internal chain tensioners let riders dial in chain tension without external tensioner hardware.
