A good trials bike gets you over any obstacle or terrain. Those from brands such as from Onza differ from BMX by having a longer frame, larger wheels and disc brakes for precise manoeuvring.


Motorised bikes in particular make for exciting rides. Models from Gas Gas and Sherco have powerful engines to conquer large boulders and rocky hills. Most even omit a seat to ease balancing and control. Be the king of all hills with a trials bike.

About Trials Bike

Trials riding began in Scotland in the early 1900s. In those days, trials events were just a matter of climbing hills, attempted on crude, four-stroke bikes with lots of low-end power and big fly wheels. Today there are still special classic classes for vintage bikes dating from pre 1965 The first important milestone in trial?s history came when the Ariel HT5 was produced in the early 1960s. It was a more sophisticated bike than its predecessors and heralded a new breed of bike that was lighter and, due to the angle of the steering head, could better perform tight turns and manoeuvre around obstacles. Bultaco, one of the big names in trials bikes, had been watching quietly in the wings and had success on the heels of this with their two-stroke engines. Montesa soon followed. And so?the era of modern trials was born. Other big names in Trials companies are Beta, famed for their revolutionary Evo series. Gas Gas, Sherco, Jotagas and Ossa Oset are all respected names in the industry. Recent bike frames are narrower, engines rev faster and damping is light to make hopping the bike easier. The seats sit low in modern bikes and recent makes don?t have seating at all as the aim of trails is to ride standing up. Recent bikes are generally water cooled two-strokes with reed-valve induction and short suspension travel. The typical weight of a modern trails bike is around 185 pounds with a 6 speed gearbox. As well as the machines themselves, even the tyres are manufactured to be lightweight as well as durable and combine flexibility, grip and strength. They are tubeless with flexible carcase construction. Designers update their machines regularly to give the rider the ultimate throttle and machine control and a bike that enables the essential perfect balance.
