Living in a dirt and mountain bike paradise I decided to get one of the best 3-wheeled recumbent bikes (trike) made, the HP Velotechnik Scorpion fs 26 Enduro. I have no intention of riding the trike on the open road. Given the mountainous and rough off-road / dirt / gravel terrain I opted for the deep knobby tires. The `Scorp' has incredible suspension. Combine the suspension with the knobby tires and there isn't much that this machine can't cover.
Some pics and description of how I have the `Scorp' set up.
Bike full setup
Rather than install a metal frame over the rear wheel to carry gear I use two Fastback Norback Flash frame backs under the bike frame. One pack (rear) for tubes and other pack (front) for tools, etc.
I mounted a bright white flashing strobe light on the left dropout (Planet Bike).
I mounted a Dinotte Quad Red taillight behind the carbon fiber hard shell seat.
In front I attached a Bacchetta One Armed Bandit light mount. To the OAB I attached another Planet Bike strobe light. I also attached a KOM Elemnt Bolt mount.
