If you are a passionate biker or only a seasoned mountain cycler, this GMC Topkick Dual-Suspension Mountain Bike is a best mountain bike you should have. This mountain bike is ideal for both trail riding and rough city riding. The MTB frame is made of 26-inch full-suspension aluminum, which is very strong. The bike uses a floating beam suspension design combined with a Zoom suspension fort with special elastomer/spring technology. This super suspension system can allow a very steady and smooth performance, no matter on what types of terrains, even on the rough terrain.
This bike features a 7 speed Shimano RD-TZ30GS SIS rear derailleur and a 3 speed Falcon MF 31 T front derailleur. This specialized derailleur system allows 21 speeds and the rear derailleur smoothly shifts without jumping clicks because of the unique Microshift push shifters. The wheels are a set of strong aluminum wheels. The rims are 6 x 1.5 inch V-shaped alloy black rims, which complete with a pair of Kenda black with yellow band 700 x 25C bike tires. Front and rear Promax disc brakes make it smoothly brake in any situation. Disc brakes are more reliable and superior than usual rim brakes, especially on terrible track condition.
Like other GMC mountain bikes, it is very rugged, comfortable and sturdy for a long time and distance ride. It doesn’t only provide superb performance, but it is also full of fashion. It’s stylishly designed.

This rating is the highest rating for a mountain bike on Amazon. Although this mountain has many high-end features, but this Mountain Bike has its drawbacks. Some bike accessories such as rear tray are difficult to buy because of unique rear suspension system. But they provide good customer service to support. I think this is not a big problem anyway. Because it is a mountain bike, so it’s not suitable for light riding. This bike is ideal for professional mountain cyclists.
