Hi StriderZE,
SADDLE
Riding the Strida requires an upright seating position so a saddle that is wide will help a lot in distributing the weight of the body. I used Brooks B67 for this purpose. It’s wide and has springs for a more comfortable ride.
LIGHTS
I used Cateye TL-LD560 front and rear. It fits on the rear rack. Not only that it’s a reflector it also has 5 modes of lighting. The front light can fit on the front tube without obstructing the fold.
SAFETIES
I use Hornit DB140 Bike Horn to warn motorists and pedestirans.
