AMBASSADOR SPOTLIGHT
Michael van den Ham is one of the nicest guys you'll meet. He's also an elite level professional cyclist, with multiple UCI and Canadian National Titles under his belt in the demanding sport of cyclocross.
Lately he's transitioned into endurance gravel and mtb racing, while still being involved in cyclocross as a coach for the Canadian National team.
He recently competed in the 2025 Canadian Gravel Championships, and while he didn't achieve the result he was hoping for, he did get into the final sprint, missing the win by mere milliseconds! Very impressive finish!
We're proud to support him with all of his cycling endeavors!

Got an eBike and a trailer but no way to connect them? We've got you covered. Our adapters swap out the stock nut for a stainless steel one with extra threads, giving your hitch a solid, secure mount. We throw in a beefy nylock nut and stainless washers to keep everything locked down. Simple, strong, and ready to roll.
