Bleed kit? Not a likely injury, but if you want to carry the weight - whatever. Most snow bike injuries involve broken bones and sprains. Need fire starter and shovel. The rest of his kit is ok.
Anything is possible and a bleed kit hardly weighs anything. I'd rather be overprepared than under prepared. We got fire starter, shovels, saw, probes, the whole shebang. WE don;t mess around in the backcountry.
There are many Snowbike kit manufacturers out there but ultimately you have to piece it together with the bike. So you purchase the kit and the bike then build it. But the kits are designed to fit on just about any modern day dirtbike. You can always book a tour with us, try one out and we can help you get dialed on what setup works best for you. Just hit us up with any questions!
