I'm a first time builder and decided on a specific build project. I plan on using the Marcagi 26" Island Tandem bike as the basis. I'm looking for recommendations and what is needed to be able to frame mount in the captains area a 2 stroker, and be able to install the sick shift kit to take advantage of the multi gear ranges that will be needed. I live in an area of souther PA which has lots of gentle rolling hills. I've been following this forum, but can't seem to come up with what is needed. I do plan on leaving the other components of the bike (brakes, wheels, etc.) all original. Thanks for helping out. I'll certainly post pics and info for others to follow in the future.
