Not sure which BMX size to choose?
Radio Saiko is a smart pick if a full-size 20" BMX feels slightly too big but you still want proper performance.
The shorter 19.25" frame combined with 20" wheels creates a more compact and responsive setup. It feels easier to control, especially when learning tricks and building confidence.
You get a bike that reacts naturally to your movement, making progression smoother from the start.
Why choose Radio Saiko?
- compact geometry improves control for smaller riders
- easier to handle than longer full-size BMX frames
- strong 3pc crank handles early tricks and impacts
- stable and predictable feel when learning
- great balance between comfort and responsiveness
Who is Radio Saiko 20" for?
This BMX is designed for younger or smaller riders who want a bike that fits properly and helps them progress faster.
Best suited for riders around 135–155 cm tall.
