On the downside, while it’s well-equipped for its price, the Spectral 125 AL 5 is best suited for intermediate riders rather than beginners, and some assembly is required out of the box. Its slightly higher price within the budget category might also be a consideration if you’re strictly looking for the cheapest bike. Nevertheless, this bike offers a good mix of quality components and features that make it a fun, capable mountain bike for trail enthusiasts who want value without overspending.
