Hybrid & City Bicycles

Hybrid, as name states, brings a mixture of a road bike and mountain bike. They tend to have narrower tires than mountain bike and usually they have a front suspension (but sometimes comes with rigid fork too). Hybrid frames falls into the specific category between road and mtb bikes. They never come with drop bar, which differs them from road bicycles. They are ok choice for commuting and excellent one for casual fitness riders.

City bikes, as their name say, are intended for urban use on paved, asphalted roads. Main use is for transport and not for recreational riding.

Road Bicycles

Trek road bicycles are being made in four different categories, depending on the riders needs. Aero road bikes have excellent aerodynamics and they are the choice for riders who are looking for speed and performance. Lightweight road bikes are excellent climbers and all-around bicycles. Endurance road bikes are built for those riders who spend a lot of time in the saddle, their intended use is to make riders as much as comfortable as possible during the long hours of riding. Gravel road bikes are for use on gravel and dirt roads.
