Allen & Natasha Mangum 

MTN.TOP is owned by Allen and Natasha Mangum whom you might know as the founders of Timbersled.  They sold Timbersled to Polaris back in 2015 and after the the sale Allen fulfilled a working contract as a technology developer for snow bikes until 2020.  Missing being a part of the industry and knowing it is something they excel at, Allen and Natasha decided to jump back in and develop new products with new technology.  In June 2021 MTN.TOP was born and the development process began.  The Mangum’s launched a new snow bike conversion kit to turn your dirt bike into an extreme backcountry snow machine on September 6th 2022.  The companies philosophy is “All Things for a Reason”.  With all their experience of snow bikes and snowmobiles they were able to produce the best snow bike conversion kit that will lead the industry into a new age.

General Manager

Rush Corder 

Rush’s first ride on a snowbike was a Timbersled back in the spring of 2011 under the wings of early adopter and first official Timbersled snowbike sales rep Randy Siemens.  After one ride he sold his snowmobile and went all in on his first snowbike kit for the 2011-2012 season.  The next year he began a professional relationship with Timbersled through founder Allen Mangum and then later as an Ambassador after the Polaris acquisition.  Rush has always been known as a trustworthy informational resource and as an avid rider and technical ambassador for the sport.  He was approached by Allen Mangum in the fall of 2021 after retiring as a Network Administrator in the IT Healthcare industry to step into the General Manager role at newly founded MTN.TOP Snowbike.  Turning a personal passion into a professional career has been an extremely gratifying experience and he hopes to continue a relationship of trust and respect with those he works with and supports as customers in the snowbike industry.

Factory Representative

Reagan Sieg

For over 10 years I have dedicated a huge portion of my life to helping pioneer the sport of snowbiking utilizing my unique skill set on a motorcycle and epic location.  In 2012 I decided to buy my first snowbike and also seek out the Owner/Inventor of Timbersled, Allen Mangum, so that I could push the industry forward.  After climbing Jackson Hole with Allen we shook hands and made a plan to work together.  The journey has been so wild and it has enabled me to wear many hats in my time with the company: an athlete, a garage dealer, a sales representative for British Columbia, the list goes on and on all the while staying focused on riding and advancing my craft.

I am excited to open a new chapter in my life as both an Athlete and as a Factory Representative with MTN.TOP Snowbikes!  We have a lot of new things to showcase along with some old standards like working with Allen Mangum and a solid team of dedicated individuals, dealers, and riders.  Our mission is to grow the sport of snowbiking through our passion and innovation.  We have come a long way in the last decade and the next decade will be even more exciting.  I can’t wait to show everyone where the team at MTN.TOP Snowbikes will take us!
