Want to buy a bike for junior, but unsure whether to go down the dedicated mountainbike route or something a little more tarmac-focused? The Alpha 24 could be the answer to your prayers

Shipping with both a pair of 1.25" slicks for road/tarmac use and a pair of semi-slick light knobblies for light off-road/CX use, the Alpha 24 represents unbeatable value-for-money; x2 bikes for the price of x1! With an emphasis of fit and safety, at this age we're convinced a flatbar setup is the way to go - scaled-down, jnr-specific integrated shifters might fit well from the hoods but are tricky to reach and operate confidently from the drops.
