Spacehorse is a fat tired road bike with a touring slant.
This blend of geometry and our 612 Select tubing creates a bike that is capable of quick road centuries, gravel racing, commuting, and of course loaded touring.
Gorilla Monsoon is a rigid mountain bike with drop bars.
Want to do mixed pavement and single track rides? Put in long days off-road? Do some fire road touring? Camping? Ride across the continent? No problem.
The Wolverine is more similar to the Spacehorse than the Gorilla Monsoon. It rides a little better too IMO but they're both fairly similar. The Wolverine has also had some issues with dropouts failing prematurely which has lead to the new 3.0 models. Some believe the changes are merely cosmetic and do not correct the overall design issue. Quality control for Soma is always much less consistent than All-City in my experience.
I have not ridden the Gorilla Monsoon but feedback from a friend that has one is that it is very much a mountain bike. Rides stiff and sorta dead on the road but comes alive on singletrack and rough gravel. Also much heavier than a road-focused bike.
