Great bike! I love it for the frame design, how it handles in different surfaces, very confortable an great when biking upslope. Had some issues with the tires and inner tubes when first assembled but thanks to the excellent Schwinn customer support, the issue was quickly resolved. I wish had Schwinn brand tires and inner tubes instead. Handle pretty good in any surface that I ride, smooth, rough, paved, or unpaved with no issues. I'm not very familiar with disk brakes but I'm getting use to it with this bike. I have a High Timber 26 MTB that I bought brand new in 2003. Superb bike. Never gave a flat, still with it original tires and inner tubes. Ran a gravel event with it last year with no issues at all. Bearings never have been lubricated and still looking and working as new. By stating that, I expect a similar quality on my Sporterra. I choose that because is a “Schwinn” and I'm confident. And 20 years from now I will be 80' and hope still able to ride my bikes. Thanks.
