I was recently fantasizing about my next trike (bought my used Rover in mid June with the idea of adding a tandem section and riding with the wife... then she decided she wanted her own trike, so current thinking is convert Rover to electric assist for her, and get another trike (probably foldable) for me) when I noticed a 10" variance between Catrike models (36" for the Villager and 46" for the 700), and half that (5") between TerraTrike models (40" for the Rover and 45" for the Rambler). This got me wondering about advantages and disadvantages for shorter and longer wheelbases.
The advantages that jump out at me for shorter wheelbase include: lighter, tighter turning, easier to transport & store, and maybe faster.
The only advantage that jumps out at for having a longer wheelbase - and it's a big one - a smoother more comfortable ride.
Can anyone add advantages for a short wheelbase (swb) or longer wheelbases (lwb) to this discussion?
Which is more aerodynamic? Which more stable? Would a shorter wheelbase make hill climbing any easier? any other thoughts?
