Bikes & Big Ideas

The frame building community lost an integral parts supplier with the closing of Paragon Machine Works, so today, Mike and Simon talk about what happened and what's next for frame builders. The first race of the Monster Pro Downhill series had some surprises, leading them to throw out some predictions for what is shaping up to be one hell of a World Cup DH season. We also discuss the dangers of kids riding Surrons and why parents might want to pay attention, plus a solid rant on crazy high hotel pet fees, and more.

Hans Rey joins Simon to discuss the letter he wrote to the bike industry about crazy-high eBike power numbers and the total disregard for the existing Class 1 eBike power limits we’re seeing currently. Hans is worried, and rightfully so, that the eBike power war is out of control, and what it means for rider safety and future trail access needs to be considered.

Are 32’’ wheels going to take over the MTB world, or become a flash in the pan like plus-sized tires did a decade ago? How did the bike industry take sudden interest in a unicycle wheel size — and are 32’’ wheeled-bikes even truly new? And, maybe most importantly, how do the big wheels actually ride? We’re joined by Daniel Yang of Neuhaus Metalworks to discuss the burgeoning wheel size, the challenges of designing a bike for bigger wheels, and get a history lesson on the evolution of MTB wheel sizes.

Today, Mike and Simon discuss what's happening, and not happening, with the investigations into the shooting deaths of Alex Pretti and Renee Good, and Kristi Noem’s complete lack of accountability.

On the bike news side, there’s an ongoing power war taking place among eBike drive system manufacturers; bike companies suing to get much-needed tariff money back; Tadej Pogacar dominating the Strade Bianche again; new bikes from Pivot, Specialized, and Kona; plus a whole lot more.

The current Kavenz VHP bikes come with a sticker that says “Made from aluminum: we give a shit,” a nod to the recyclability and (purportedly) lower environmental impact of aluminum compared to carbon fiber.

But Kavenz is also openly developing the next-generation VHP platform — and it’s using carbon tubes bonded to aluminum lugs. So, why change materials, especially when aluminum is such a big part of the brand’s image and ethos? Why document the whole process for the public, rather than developing a new bike in secret, as most brands do? Is the environmental impact of aluminum even really lower? We sat down with Kavenz founder Giacomo Großehagenbrock to discuss all that and much more.
