BootSaver was founded in 2018 by TNR Machine Works, LLC with a simple goal: build better parts for snowbikes. What started as a small in-house machining operation producing shifter and footpeg extensions quickly gained attention from riders looking for stronger, better-designed upgrades for riding in the snow.
Over time, TNR Machine Works expanded further into the snowbike world, including building complete snowbikes, developing specialized accessories, and continuing to refine new ideas for riders who spend their winters in the mountains. With a background in machining and fabrication, the focus has always been on building parts and equipment that solve real problems and hold up in harsh winter conditions.
That same passion for snowbiking eventually carried over into the RC world. TNR Machine Works began developing snowbike conversion kits for the Losi Promoto-MX RC Motorcycle platform, bringing the experience of real snowbiking to RC riders through realistic suspension design and purpose-built components.
Today, BootSaver and TNR Machine Works operate side by side—designing, machining, and building products proudly in Montana. Everything is made in-house with pride, with a strong emphasis on quality craftsmanship, practical engineering, and American manufacturing.
