Your first BMX doesn't need to be the most expensive one: it needs to fit you, be tough and easy to maintain.
1. Pick your discipline
- Freestyle (street/park): 20" wheels, steel frame, small gearing (around 25/9), wide tyres.
- Racing: light aluminium frame, low-tread tyres, sizes by top-tube length (Micro to Pro XXL).
2. Size: the top tube (TT)
BMX bikes are sized by top-tube length. As a rough guide: 20" TT for riders up to ~5'7", 20.5" up to ~5'11" and 21"+ above that. Small kids start on 12–18" wheels. Test-ride when you can.
3. Materials
Look for a chromoly steel frame, fork and bars (at least the frame) and a sealed-bearing rear hub. Hi-ten steel is heavier and bends sooner, but is fine for a first taste.
4. Brakes
A rear U-brake is the sensible way to start. Many street riders remove it later, but learning with a brake is safer.
5. Budget
Complete bikes from specialist brands (Kink, Cult, Sunday, Haro, Mongoose, Fit, Colony, Chase, Elite...) cover entry level to pro. Keep some budget for a helmet and pads.
