Strengths
- •Mongoose name brings a long warranty and a consistent retail presence
- •Slightly more aggressive geometry feels more confident on real trails

Sizing Comparison
HILAND offers two wheel sizes (26" and 27.5") so it accommodates riders 5'4"-6'5" with appropriate sizing. The Mongoose Flatrock comes in a single medium frame around 5'8"-6'0". For shorter or taller riders, the HILAND's wheel-size flexibility is the deciding factor.
