WebCyclery.com is the biggest trials dealer in the US. We import Echo, Inspired, Trialtech, Jitsie, Crewkerz, Racing Line, TNN and many more trials brands and we've got more trials bikes, frames, and parts than anybody in the country. We have a real brick and mortar shop, with real mechanics, real tools, and real inventory. As you might expect, we get a lot of questions about bike trials. We've created this Bike Trials FAQ page to try and answer some of the most common questions people have when first exploring the sport.
TGS stands for Tap, Gap, Sidehop and is used to describe a style of trials riding that is mainly performed in urban areas. It tends to focus on going as high or as far as possible and is usually less creative and dynamic than street trials. Dropgaps (a gap where the landing is significantly lower than the takeoff) also feature prominently in this style of riding. It emerged and is still most prevalent in the U.K., due in part to the concentration of cities and urban riding opportunities there. TGS bikes are often heavier and more durable than other bikes so that they can take the stress the riders put on them.
Competition style riding is, as you might expect, a style of riding used primarily by riders who compete in trials events. Competition riding focuses on using efficient technique and form with as little wasted energy as possible. Riders practice very technical and precise moves that are often required in competitions. Comp style riders usually prefer light bikes that are as efficient as possible at getting them through a section in competition. Competition bikes usually bear the least resemblance to normal bikes both in geometry and appearance. Comp style riding and TGS are less distinct from one another than from street trials, and sometimes there is little difference between the two.
These different styles are constantly evolving and riders are frequently blurring the lines between different styles. Many talented riders can ride street trials lines on a comp bike or vice versa. And of course there are riders who may not fall under any of these styles.
