I rang the place in Niddrie today to ask them some more details... The guy said that only some of them are allowed to be ridden on the streets. The ones that aren't are generally the racing looking ones.
They have only gotten the bikes in the store this week so they havent got the internet site set up properly and haven't decided on an exact price.
He said that some kind of modification needs to be done to the others to make it legal to ride them on the streets. They don't need to be registered because they are all less than 50cc. 49cc and 47cc
Price wise I am not sure. There was one on Yahoo auctions for US$270 + US$140 shipping. And there's a mini harley in a shop window near my house for $750. The woman that I spoke to was a clueless bitch and let her stupid rat dogs jump on me and bark. I felt like grabbing the bike and running over the dogs on my way out.
