the Juexing is a company from China making E-Scooters since 2004, delivered in two days tracking delivery was real, if i may add info for the seat my model didnt need all the hard wear to attach the seat removed the bolt took out the cirular two inch metal tube to harness the seat i did need the metal brakets that the bolt went through put them back in place so the bolt needs them , theres a black five inch lever attached to the pole on the top it needs to be pushed downto clip onto the pin, then the seat fits that lever should be faceing toward the front of the scooter , the brakets and bolt to tighten the seat in place is all you need you wont need the metal tube like hardwear take it off, push the bolt back through with the brakets side it over the five inch lever to fasten it in place, it dose not have a manual, i think it should to explain the the details more clearly, thier very clear on charging the battery, so read that its very important to know when and where and why to follow these directions or it could cause fires , charge out side in a garage, or park or charging station, the charger as a open vent fan it needs to pull in air to keep the elements cool, charging only took seven hours, it came with tools you dont need except to attach the lights the throttle control remove the lock bolts attach and put the bolt and lock nut tighten with the L in wretch, Thanks ,Juexing Company ,
