Just purchased a xp4. I’ve never owned a bicycle but I’ve know how to use one since I was a kid. I’m 44 now btw. I have a motorcycle so I’m familiar with that aspect of riding however this question is more regarding the xp4 and its gears. When riding and changing gears to 3rd gear the chain seems to jump around and not settle on that gear. Gear 4 and 2 work fine but 3 just won’t stay put. Am I peddling too fast for that gear? Do I need some adjustments or tune ups? Does lectric cover any initial visit to a shop to check out the bike?
