My first Beach Cruiser Limo Stretch build in 2007! Went very well, so I had To build another one! It has a Subaru 33.5 cc 4 stroke engine, friction drive. At the time I was around 225 pounds!!!! This thing would still go 29 to 30 MPH!! I'm now around 207 pounds, and this GTS with me now go's around 32 MPH!!!!
