User Manual Gotrax ES4 Electric Scooter

No it does not have brake lights.

I was actually amazed at how smooth it rides, and how stable!
The air filled tires really do a good job holding on a corner.

I don't know. Because I never replace battery yet after
purchase. It is only two and half month old.

Yes the tires do come inflated. However, if you ride it often you
can get a flat tire.

As weird as this sounds, try unscrewing the clip on the fender
and turning it around. we have found that this will work
sometimes if the front hook is either catching too hard or not
enough.

Make sure the light on the charger turns green. Ignore the
display on the scooter.
