Tonight's question: Direct v. linkage steering. Pros & cons of each?

It all depends on the particular bike or trike design.

Direct-Handles like a Porsche
Linkage-Handles like a luxury car
You have to ride each to find out what you like best

Linkage requires twice as many (at least) pivots built into the frame, along with a fair amount of specialized hardware. Direct can use mostly standard bicycle parts.

Linkage is useful in cases where the bike or trike's design precludes direct steering. Beyond that, the geometry of the bike (fork, frame, angles, trail, wheel diameter, etc.) determines its handling qualities.
