The Reacto is a star performer on the road and it’s good enough to justify big upgrades down the line
Superbike-like ride
Ultra-modern design
Clean cockpit
Better wheels and tyres would really let it shine

One month into our longterm test and the Merida Reacto LTD road bike is already impressing us
Effortless straight-line speed
Scything high-speed cornering capabilities
Dampening when dealing with large impacts
Doesn't come with tubeless tyres as standard
The rear light is far from reliable

Some buffeting in crosswinds
Quite high geared
