About Dan
📍 Boulder, Colorado
Software architect and e-MTB rider based in Boulder, Colorado. Former mountain biker (Yeti SB130, Santa Cruz Tallboy), regional cyclocross racing background. Rides a Specialized Turbo Levo on Front Range trails and bikepacking routes. Reviews gear based on real climbing loads, motor characteristics, and field conditions — not flat-ground spec sheets.
The switch to e-MTB wasn't an exit from mountain biking. It was an extension of it. The Specialized Turbo Levo is his current daily. Before that, he owned and sold a Trek Rail (found the geometry too XC-focused for his preferences) and built a Bafang BBSHD-converted hardtail for around-town and gravel riding. He hauls bikes in a Toyota Tacoma with a 1Up rack, does week-long bikepacking trips on Colorado Trail sections and in the San Juan Mountains, and pays more attention to motor torque characteristics and range under climbing load than to any lifestyle framing.
The day job is software architect at a mid-size SaaS company — enough engineering fluency to read a motor spec sheet without help, enough distance from the industry to not be a brand advocate.
Ten27 is where that perspective lives in public. Technical evaluations, sourced framing, honest takes on every price tier, no fabricated testing claims.
