To back up this off-road performance, you will need disc brakes, and the Traxion has them, and they will be very helpful on a trail. Like the other bikes, the Traxion has a Shimano triple front crank, but it is equipped with an 8-speed cassette on the rear. It’s going to give you a few more gears for those demanding climbs. The brakes are rim brakes on the Mesa 3, but on the Mesa 2, you get mechanical disc brakes which give good stopping power. The gearing is Shimano, and they make excellent quality components. You won’t struggle with hills as there are many options. Testing determined the safety harness does not comply with voluntary industry safety standard, ASTM F , and the stitching can rip, posing a fall hazard to the user. The strap anchor can become dislodged from the helmet when sufficient force is applied, and therefore violates the CPSC federal safety regulation for bicycle helmets. Full Suspension Just like it sounds, full suspension mountain bikes have suspension built into both the fork and frame. These bikes are great for riding on super rough terrain, though they tend to be heavier than hardtail bikes. Hardtail Hardtail mountain bikes have front suspension and a rigid frame. This style of mountain bike is best for dirt paths and trails. Hardtail bikes are lighter and more agile than their full suspension counterparts, but they’re not as well suited on ultra bumpy, rough terrain. Schwinn mountain-tuned aluminum frame and suspension fork are great for exploring beyond dirt paths and gravel trails. Great for riders who want to take their mountain biking to the next level. Schwinn’s mountain bikes are all single frame size bikes, which are designed to fit most adults. Single frame adult bikes may be available in a range of wheel sizes, from 24” up to 29”. While the wheel size can offer guidelines for the recommended height range, always check the product description for each bike, as it may vary a little by model. Check out the chart below for a complete list of height ranges. Featuring front suspension, 21 speeds, and all-terrain tires, these bikes are built for grand adventures. Mountain tires rovide traction and stability out on the trail. Aluminum double wall rims offer lightweight strength that won't weigh you down. Commuter bicycles are built to take on the city streets. This bike is suited to shorter people than the Traxion, so Schwinn has given it smaller wheels at the size of 26?. This makes it much better for the user and does add a lot of control to the rider but takes away some top speed. Schwinn High Timber, like the Mesa, is a hardtail mountain bike and comes in many different models. If you’re at the height of 5’8? to 6’2?, this bike is going to suit you. If you require smaller, the Protocol below is the right bike for you. Then we come to wheels, and unlike the Mesa, the High Timber has various sizes. You have wheels as small as 24? for juniors, and then it goes to 26?, 27.5?, and 29? for tall adults.
