Small Town Business Serving a World-Wide Racing Industry

For a little over a year, Grothus Dragbikes (GDB) has been proud to call the welcoming and  flourishing town of DeWitt its new home for both our motorcycle dragbike product manufacturing & sales as well as our professional race team headquarters. With involvement in the motorcycle drag racing industry for well over twenty-five years, we at GDB are proud to be an industry leading manufacturer of 200+ mph motorcycles built in the Crossroads (to Opportunity) Business Park.

A vision of a motorcycle drag racing team that started in the 1980’s has now grown into a world-wide business serving customers from all across North America to as far as Greece and Saudi Arabia. With a desire to pursue our manufacturing interests, we are constantly innovating and engineering products to take motorcycle drag racing to newer and safer heights. While doing so, we are able to put our STEM skills to use day in and day out as we build drag racing components and a knowledge database that helps ourselves and our customers win on race day. Grothus Dragbikes allows us to combine two things we are passionate about – first and most obviously, Drag Racing – secondly, manufacturing. Merging both of our passions allows us to be a unique business as we truly “race what we sell”. This means that we are able to rigorously test our products at both the shop and racetracks across the nation in order to make beneficial changes to them prior to their official release to the consumer.

Many of our high quality components, now all manufactured in DeWitt, were on display as part of Manufacturing/STEM Fest presented by the DeWitt Chamber & Development Company and the Iowa Governor’s STEM Advisory Council earlier this month. We were proud to exemplify our exciting contributions to manufacturing with over 1,000 engaged students from rural Clinton County School Districts, including the Central DeWitt Community School DistrictSt. Joseph Catholic School & Calamus-Wheatland Community School. From the Science behind rotating mass and enhancing combustion, to the Technology we use with CAD CAM software in the designing, testing and machining product phases, to the Engineering of lighter, stronger components, to the Math of calculations of weight distributions and forces, STEM is very much a part of the racing industry. STEM Fest was an incredible opportunity to help showcase the varied and exciting industries where manufacturing plays a pivotal role. Speaking to students about their interests and what excites them about manufacturing made for a successful event indeed!
