Bike Description & Terrain

An amp'd up geometry made to eat up gravel with enough tire to absorb the vibrations of a rutted-rocky trail. Redwood wheels have 27.5" thru-axle/tubeless compatible rims. Allowing a 2.6" tire to clear this frame without issues (tire and rim combos vary). Whether you are on trails most gravel bikes would shudder at or taking in newfound sights on your next bikepacking trip the Redwood is ready.

Gravel, Single-Track, Bikepacking it does it all.

For the Rugged Adventurer
Perfect for Rough Terrain and Long Trips

The Redwood has a setup that allows it to be capable on terrain meant for a hardtail mountain bike while giving you plenty of rack mounts for multi-day bikepacking trips. This is a great option for someone who is looking for a gravel bike that can go out a little further or a person looking for a do-it-all commuter bike.

Great Speed with Steeper Climbs
A Versatile Bike with Excellent Range

The gearing range is set up for folks looking to get up steep climbs while offering a solid top-end speed. At a moderate cadence the Redwood can generate a top-end speed of about 25-26 mph on flat ground. The Redwood's geometry makes it a great bike for climbing.

The best bike out there under 1K

i bought by redwood late 2023 it now has over 2,400 miles on it including the GAP & C&O and the eastern divide route from west VA to Florida in winter just got done , this bike can handle just about anything in my open it’s more like a ridged mountain bike , it’s at home on single track , Forest roads no matter how rough , double track and will absolutely bomb pavement down hills , after all that it’s still a amazing bike no issues on the trip other than a broken chain , I did make a few changes for the eastern divide changed the crank , chain ring to 32T , and added the red shift seat post

if you want a bike that can handle it all and not brake the bank look no further the Poseidon redwood is your bike

Love my Redwood

I bought a Flatbar Redwood about 8 months ago and this thing is a monster. I can roll on mild gravel, single track, and I can do most mountain bike things with it. Definitley plan on getting another Poseidon (probably an Ambition X) in the near future. Also, the customer service is top notch!
