Geometry and Sizing
Let’s talk about the sizing of this bike so you can decide if it will be the right size for your height. Check out the Dougsterbob Size guide to see what you need to be looking for when shopping for a new BMX bike.
The most common cause of failure in BMX is an improperly sized BMX bike.
Frame Size
| Toptube Size 1 | 20.00″ |
| Height Recommendation | 5′ to 5′ 3″ |
| Big Bike Background | 4′ 9″ to 5′ |
Frame Geometry
| Head Tube Angle | 75º |
| Standover Height | 8” |
| Chain Stay Length | 13.2” |
| Bottom Bracket Height | 11.6” |
This is a standard geometry. The chain stay is about 1″ lower than average and the chainstay length is slightly longer but not much. The geometry on this frame will feel pretty standard.
Other Geometry
| Fork Offset | 30mm |
| Bar Rise | 7.75” |
| Bar Width | TBD |
| Crank Length | 170mm |
| Stem Specs | 50mm Reach Maybe? |
| Gear Ratio | 25/9 |
The fork offset gives this bike a stable feel while the small 7.75″ bars make the bike even more perfect for a smaller rider. I feel like the crank arms are a little bit on the long side for a bike designed for a smaller rider.
Quality & Weight Limit

Conclusion
This is a good bike for some riders. But it will not be a good choice for everyone since it is a very small and compact bike. The price is a little high for the extremely low quality that you are getting but when you look at similar quality options, this bike is par for the course.
