Our Team

We are an experienced engineering team with decades of experience working with the best riders on the planet.

Through testing and data analysis from professional riders and legends of the sport, our system has quantified what a well tuned bike looks like.

We've been able to replicate this to any bike, assuming the suspension has the range. Our system has also uncovered hidden benefits of existing products. We can also highlight where things can be a lot better. Product managers, engineers, and suspension tuners have had early access to our product and have used it to produce some really exciting results.

Friends of Motion Instruments

Woodside Bike Shop

Greg Dertorossian, owner of WBS, introduced us to Greg Minnaar when all we had as a prototype was a bent curtain rod connected to some dubious electronics taped to our handlebar. If you need a bike and want to visit a really crazy (hair on fire busy) bike shop, hit them up in Redwood City. Greg has done a lot for the community and has sponsored the Woodside Beasts, a local high school mountain bike team, for many years.

Santa Cruz Syndicate

We’ve learned a lot about our product and how to make it better working with the Syndicate team. This is a fantastic group of dedicated folks pushing the boundaries of Downhill racing. They have been very generous with their time and have included us in some really fun events. For us, working with The Syndicate put us into situations that really stressed out our product. Our technology made a huge leap forward working with this team.

Santa Cruz Bicycles

The engineering team at Santa Cruz Bikes, led by Nick Anderson, helped us a TON. From modifying a shape of a link on the V10 to accommodate our sensor, to providing proprietary leverage curves for prototype V10s. They have gone out of their way to support us. This is a fantastic company.


A heavyweight in the industry, Fox builds some of the best suspension out there. We have learned a lot testing alongside Greg with Fox. If everyone could have a Jordi Cortez or Ariel Lindsley by their side, there would be no need for our product. This is a great company focused on high quality.


Adam Krefting has built up an exceptional product line for mountain bikes and motorcycles. We have used CushCore in our MTB testing and we can quantify the benefits. We have also used KreftMoto on our dirt bikes. We are big fans. If you’ve got a KTM, Husky, or a modern mountain bike, you need to hit them up.

Ibis Cycles

Ibis is an iconic mountain bike brand founded in 1981 by a young hippie named Scot Nicol. We've partnered closely with Ibis on developing our data analytics platform. To date, they have generated more data than all of our internal testers combined. Their insights have allowed us to improve our product, specifically in the areas of dynamic Front/Rear balance. If you own an Ibis or are in the market, just know they're the real deal. They leave no stone un-turned during the development of their bikes.


We’ve worked with Ian Massey from Trail Technique. If you are a bay area or northern california rider looking to unlock the mysteries of going fast, check out Ian. I (Rob P) took a class from Ian and was surprised to discover how big of a difference tiny changes in body position and weight can have on your riding ability.

Yeti Cycles

We have worked with Yeti for a while. We’ve participated in their legendary lunch rides (and got smoked). We are lucky to work with this team. We will be introducing products and technology conceived from interaction with the Yeti team.

Brian Lopes

We have had great test sessions with Brian Lopes & Mike Davis from Mad Racing. Brian is a beast on a bike. If you’re racing against him as a pro half his age, best of luck to you:-) We look forward to continued testing with Brian and Mike in the coming months.

DVO Suspension

The guys at DVO rock. Bryson Sr. has built a great company and assembled a great team. It boggles my mind how difficult it is to build any hardware, but then add on the intricate tolerances needed to build suspension, wow. DVO is a smaller scrappy team and we are happy to be able to work with them.

DirtLabs Suspension

This is a fantastic suspension shop located in Longmont, CO. Owned by Mike “Luby” Leubesmier, these guys service 1000s of dampers per year and can provide custom tuning. We have discovered a lot of over damped bikes out there and these guys can help get you the perfect ride if a hardware change is needed. DirtLabs has been an early user of our technology and has provided great feedback.

A Singletrack Mind

Dylan Renn was one of our first riders on our system. If you are trying to become a better rider, make sure to look him up. While we believe a properly tuned suspension will unlock the door to speed and comfort, proper technique trumps setup any day of the week.

Launching 2020

We are excited to get our product to market. Stay tuned for our launch. Send us an email to pre-order@motioninstruments.com to be first the first in line.
