The GMC Topkick 21-Speed Mountain Bike features a full-suspension, strong aluminum frame that utilizes a floating beam suspension design that is mated to a Zoom suspension fork with elastomer/spring technology. The Topkick's drivetrain starts with Microshift push shifters. These shifters control Shimano's tried and true TZ-30GS derailleur. The drivetrain finishes up with a strong aluminum wheelset featuring V-shape rim profile and high-flange alloy hubs. Stopping is handled by Promax disk brakes on the front and rear. These brakes are vastly superior to rim brakes, especially under adverse road conditions. True to it's GMC roots, this bicycle is rugged, good looking, and built for the long haul.
Color: Matte Black/Blue

So if you're one of those types that love a long distance, bike ride (or touring) this bike is for you, just make pretty sure that you got a large hike bag of replacement parts (Water and trail mix is VITAL!!) so you don't end up stuck in the middle of absolute nowhere. However, if you're planning to go on a cross country ride with this model, install reinforced shocks, slightly large disc brakes, off road tires with teflon strips (for more thorn resistance) if necessary install a dual crown fork for unforgiving terrains and utmost importance, GOOD BIKE LOCK!! NOT THE 1/2 @$$'D ONES AT WALMART!! For extra security and anti-theft procedure. Ride like you mean it, PEACE!!
The BAD thing I would like to inform about is the rear tire was flat, and found the tube to be punctured. I capitalize BAD because this was the case for BOTH BIKES. Each bike in their own box and packaging. What are the odds that BOTH rear tire tubes are punctured? Maybe the manufacturer has a disgruntled employee on the assembly line? Or their quality assurance program needs to be reevaluated immediately. None the less I hope the manufacturer learns from this so they can prevent further issues.
Besides that, great looking bikes. Can't wait to try them out as soon as I go get a couple of new tunes and install them. I am really glad that I decided to sneak in an assembly before Christmas otherwise my grandkids would have enjoyed only looking at the bikes on Christmas day. I have no doubt that the bikes will perform above expectations but will pass along any details should things arise.
