SimWorks USA Making things for any spaces of in between.. Times are different now. We’ve realized that the reason is based on a lack of understanding through consumption.

Imagination & Creation of your life quality

Human beings have lost a lot of things so far which cannot be regained completely. Nature and society remind us how much we still don’t know about this world we exist and we’ve noticed that the same issue is happening in our bicycle world. In former days, there was a time when bicycles were locally built by hands and welded with carefully selected tubings and probably those bikes went to our own grandparents. After that, over the decades, Japan eventually became the most important place for bike manufacturing especially when people around the world started using bikes more recreationally. A center of manufacturing is located in other countries while companies in Japan receive their ideas and products massively without any hesitation. Has the Japanese bicycle industry lost not only their production power but imagination as well? Radically, a quite different market could be seen here in Japan if we tapped into our roots: we should've made products by our own hands, increased lines on communication, used the knowledge that we did have, and accepted what we had too much and not. Simworks has started taking an action to change the system against the trend of mass production. Our goal is to give our clients the highest quality of product! We think it is necessary in order to guide the next generation. This is what we stand for and this is our passion we’d like to share with you.

【New Color】Doppo Ronin - Golden Moss
We’re pleased to announce that we received an inventory shipment of Doppo Ronin frame sets from Japan on Monday of this week, and they are live in the web store!

This fresh batch is being offered in a really great deep green we’re calling ‘Golden Moss’. It’s got some really handsome golden metallic effect that comes alive out in the sun.

The specification on these bikes is otherwise unchanged. The same great Japan-built ATB allrounder. Set it up 700c as a nimble gravel style bike, or run it 650b with a bit wider tire and explore it’s capabilities as a light bikepacking bike, or adventure bike.

With stable and intuitive handling characteristics, frame specifications that allow for a wide range of parts sourcing from your favorite brands, you’ve got the foundation for a bike that you can build to suit your riding style, and easily adapt should your preferences change.

Built in small batches in Nagoya, Japan by a dedicated 2-person team, Shin Hattori Works, the Ronin is the iconic offering within the Doppo by SimWorks lineup- arguably the most versatile and certainly longest standing model to date.

SimWorks Ramen & Gyoza & RC & Yoyo Party Ride

This was totally the biggest SimWorks group rides in the books. Thank you ALL for showing up, joining the ride and coming to party with us at the SimWorks Showroom.

It means the world to us to see our community show up with so much support, love, and encouragement. Events like this take a huge amount of work to make happen, but seeing everyone together, smiling, riding bikes, eating, playing and having fun makes it all feel entirely worth it.

Our talented content creator put together this wonderful reel that captured the happiness and excitement of the massive group ride and Ramen/Gyoza party, RC/ Yoyo jamboree that we hosted at our showroom during the MADE show weekend in Portland last month.

We were so fortunate to have our talented Ramen and Gyoza chefs come all the way from Japan just to share their love for food and their craft with everyone for this one special evening.

They spent FIVE DAYS preparing everything from scratch. There was so much care, time, and thoughtful preparation behind every bowl of ramen and every plate of gyoza all for those few hours when everyone could simply enjoy it together.

We were floored with the turnout, so blown away with the tremendous show of support that we got from our community, fans and friends who were in town from all over the world as well as locals alike.

And this party definitely didn’t happen by ourselves.

Huge thank you to Chris King for letting us throw this big crazy party on their property!

Big love to our own Aaron from SimWorks for rising to the challenge and leading such a MASSIVE group ride through the city.

From all of us at SimWorks, thank you sincerely and wholeheartedly for being part of this very special day.

🙏 ARIGATO GOZAIMASU!!! 🙏

【NEW】SimWorks Rising Hearts Pocket Ts
Artwork by
We asked our favorite friends Josh and Rachel from Variety Shop to help us update our iconic, much-loved Heart and Arrow logo.

They turned it into something cute and powerful with the hearts rising like the sun. They really knocked it out of the park.

We chose earthy colors that feel right for desert rides like this, nature rides, and everyday city riding.

The T-shirts that we elected to use for this go-around have become somewhat of a go-to around here; Comfort Colors Pocket Ts.

【New Color】SimWorks Rover Socks 2026
Our favorite super comfortable socks are now available in new colors: ‘Mountain Sunset’ and ‘Chestnut.’

They’re a great seasonal option for people just looking for a go-to casual sock that could certainly be worn on a bike ride, thrown on after a chilly day of surfing, or hanging out in camp or just strutting around town.

Some quality merino blend socks are a great staple item that can always find a use in just about anyone’s wardrobe.

The colors are memorable- kind of leaning in to 70s retro vibes, they’re a nice weight that we would probably characterize as 3-season.

Made by / North Carolina, USA

Material Construction:
39% Nylon / 29% Merino Wool / 29% Polyester / 3% Lycra

7” cuff length

【Presale】2026 Doppo ‘High Plains Drifter’
Thank you to folks who placed a Presale Order. We have sold more than a half of this batch so far.🙏

Presale for High Plains Drifter frames is closing soon. The frame & fork sets are shipping sometimes in May 2026.

We will be showcasing this bike at .cyclery for the SimWorks Pop Up Tomorrow, FRIDAY 10am-6pm!

If anyone happens to be at , please come see us and say hi at AMG Cyclery in Seaside (18mins from Sea Otter Event) tomorrow!

The ‘High Plains Drifter’ is handcrafted in small batch production here in SimWorks’ home town of Portland, Oregon.

As we did the 1st model in 2022 is a concerted effort in supporting local tradespeople, and contributing to a local economy of skilled creators that continually demonstrate a commitment to exemplary work within our industry.

High Plains Drifter is not trying to skimp on weight, or offer any performance metrics.

It’s a durable, chromoly bicycle frame with butted main triangle tubing intended for off-road riding applications.

It was designed and built to be a lasting machine to take you on a lifetime of memorable adventures. It has ample clearance for 27.5″ x 2.6″ or 29″ x 2.4″ tires.

【SimWorks by Panaracer】SUPER YUMMY 26”
Our classic Super Yummy 26” has been loved by riders across a wide range of bicycles. It’s also one of our favorite tires, one we’re very proud of.

Rounding out the common all-terrain wheel size options, and allowing riders to dust off a classic hardtail relic or build up a versatile getaround machine, lovers of the 559 size can now rejoice and satisfy their craving for a modern, durable and fun-loving tire.

【NEW COLOR】Sim Works Hoodies!
Sakura Season again 🌸 Spring is here, but it still gets chilly once the sun goes down, so a hoodie is still an essential.

We added fresh new colors on our Hoodies as well. We had fully depleted our remaining stock on all of our hooded sweatshirts, so we reupped on 2 great looking new color- Storm Blue and Olive.

The understated sewn on patch is back. Heavier weight than our new crewnecks.

Little roomier fit. Kangaroo pocket. In these shoulder season months, the perfect post cold-plunge warm up, or cozy layer to lull you in to that sated fireside camp daze before you turn in to sleep under the stars.
