My current bike is a zeforia, I’ve only had it since the beginning of march and it’s already taking a crap on me. The battery is starting to die faster, I’ve had to replace the tubing on the tires twice, my brakes are starting to get worse, and the bolt on my left pedal is completely stripped. My original plan for a replacement was the ride star q20, my friend told me it was a good starter bike with room for modding, but I’m looking for other alternatives just to keep my options open. Give me suggestions, preferably with a price range of 600$ or lower.
