My son, David is building a FWD MBB recumbent. The last couple of years has produced several successful home-built MBB from which he has drawn inspiration. The Cruzbike conversion has also influenced his choice of frame and design. For the frame he is using a Walmart 24″ suspended MTB Tiara Pro. The Tiara Pro has a lightweight aluminum Y frame with room for a curved wood seat.
Rear suspended stays and front forks were modified to hold 700 c wheels and fit the aluminum Tiara Pro frame. An anAtomic curved seat was constructed to fit Tiara Pro frame in a reclined position. My construction process of the seat can be found here and a link to the PDF instructions are included on that page.
A 3/4″ conduit seat post was fabricated with a shim to fit the down tube and the curved wood seat attached.
David modified the rear triangle from another bike so that he could put a 700 rim from a road\race bike on the back as well. He will remove these brakes and stick regular road brakes on it as well.
This is the latest picture I have of the MBB FWD sans the 700c wheels. Last week I went to visit David and work on my suspended stick bike. While there, David took the MBB on a ride around the neighborhood. On his return down the street, he look like he was running near 30 mph although he complains of it still being a bit shaky.
This weekend I’m to return to finish my stick bike and I’ll get recent pictures of the MBB and a video of David riding.
