Our King max speed is 50km/h.

All AOSTIRMOTOR E-bikes are water-resistant. You can ride in wet conditions, but we strongly recommend that you do not ride in rainy or overly wet environments to protect the bike and to ensure rider safety.

Perhaps you could have a look at our Queen. These two electric bikes are of the same series. Right now, we only have two options. No more colors for now. Of course, if you want to give us feedback, you can contact our official email address (aostirmotor@gmail.com). We are willing to listen to whatever our customers have to say.
