I always put a drop of finger nail polish, or Loc Tight, on the bolts and "screws" to avoid loosening...
I purchased a kickstand because the first one came apart while riding and could not be recovered. I was not "tough" on my kick stand, but the bottom screws on, and apparently had come loose and came off while riding. Unfortunately I didn't notice while riding what the noise was from. When I got where I was going and tried to set the bike up, I went to find it and could not discover where it was lost and had to order a new one. I'm hoping for better luck this time, but I definitely tightened that screw.
Love the bike. Want to buy another battery , but I'm afraid it's going to take a long time to receive it. So I'm apprehensive about investing more money into my ride .
The parts I ordered were of high quality and the shipping was fast. Their customer service has greatly improved. I will be ordering from them again.
