in my opinion, i would too, i bought the lei 140cc and every little thing apart from the engine was rubbish, you are better off getting a pit pro 125 or dHz for the same price
If you want a cheap bike I wouldn't go any lower than an atomik nitrous. TDR, LEI, Motoworks, atomik motoX are all complete garbage. the Atomik nitrous isn't very good but at roughly the same price as the rest of junk it is much better.
If you want a cheap bike that's actualy half decent look at a pitpro 125rr or any of the DHZ bikes
