    researching custom tandem trikes

    We are researching custom built tandem trikes and are wondering what an "adjustable boom" is. Is this a way of adjusting the seats? Sorry if it is a dumb questions, we are newcomers in the land of recumbents. Thanks.

    The boom is the big forward tube that connects the crank axle on a tadpole trike or a short wheelbase recumbent. It is often 1.5" diameter or larger and usually has a telescoping arrangement that allows the cranks to be adjusted fore and aft to fit riders of different leg lengths (or X-seam).

    There's a highly adjustable ICE trike listed on BentRider Online.

    BF prohibits sales attempts except in sales formums. This is not my trike and I have no interest in its sale

    Thanks for the reply. If a trike had an adjustable boom, would the term adjustable seat mean that the reclining position of the seat would be adjustable but the seat wouldn't move forward or back?

    It could be either. Some trikes have seats that adjust to different angles by changing the length of the piece behind the seat while at the same time moving the seat back and forth on the frame (e.g., Terratrikes) and others have the seat angle fixed while you can still move the seat along the frame. There are a few old Linears out there that allow you to move the seat along the frame but they are rare as hens teeth in the tandem format. I've ridden a Tandem GS GTO. It's a fantastic trike but the cost will make your eyes pop. I have the single version of the GTO and love it.
