After purchasing your bike, a 30-day tune-up is recommended. This is outside of your warranty coverage, and SWFT recommends this for basic bike care and maintenance to ensure that your ride lasts. A local bike shop can tighten anything that could have come loose while you have been riding, and they can set you up for a lot of riding. After this initial tune-up, we recommend a yearly tune up unless you run across other performance issues. Your local bike shop is your best resource to keep your e-bike functioning safely.
