Like any mechanical device, your e-bike has a break-in period. We recommend doing an inspection and tuneup after the first 100 miles to review any changes and adjustments needed. This also helps you to get acquainted with how your riding habits reflect on your e-bike.
A standard multiple-point security inspection costs around 30 to 75 USD at any local bicycle repair place. It's basically a multiple-item inspection done by a mechanic. If you have bike experience or a cyclist friend, these are the things you can review at home. We have handy videos that are available on our YouTube channel.

Fork turning freely and smoothly
Check they are properly lined up with the front tire
