Thanks Pablo and Mabman.....I think the in frame with a shift kit would go in easy, and im not particulary worried about the long drive chain. I could use a beefed up bmx chain and probably be ok. The issue for me i guess is the leagality in or. This bike has become my regular rider. We go shopping , picnicking etc and it usually has sumthin in or on the carrier or bags. Soooo, im leaning twards the suburu or honda motor. Now to come up with a mount. It looks to me there is plenty of room and a number of practical mounting points available. The real quandry for me is the drivetrain. Im not sure how an (automatic drive ) works and if you could suggest where i might find a discription or some pics that would be great. I can figgure how to drive the rear wheel but just unsure haw to incorporate the gears wo a jackshaft, which i dont want. I guess i need to get more familiar with how the gebe and station driveterains work. Would one of those options allow me to use the bike and gears without the drag of the clutch .?? i dont care about the weight, its a cargo bike LOL... Jeff
