3 out of 5 are motor bikes... so you really mean 3 ebikes and 2 amazing bikes you've never heard of. Accurate titles are important in journalism. Otherwise you waste your viewers/readers time and then we go watch and read something else.
Been using them since October & I think they are amazing. Price is ridiculous for what's in the box, but I suppose early adopters pay for development, hopefully that will drop. They have saved me from certain rim damage a couple of times so perhaps paid for themselves in a way.
