Cotic BFe Review: Burly Metal, Soft Touch

Jul 2025 · By Logan Watts

Read our full Cotic BFe review to see why the 7th generation model might be one of the most balanced and capable hardtails Logan has tested…

Highs
  • Superb geometry that’s progressive in the right places, making it an excellent trail bike and a very confident descender that’s not over the top in other areas, allowing it to feel great climbing and pedaling for hours on end

  • Tubeset feels sublime; it perfectly toes the line between comfort and responsiveness

  • Very long front-center and relatively decent stack is a great fit/feel combo

  • Sharp paint and subtle graphics

  • Good tire clearance and a decent set of bottle/cage mounts, although a third under the down tube would be welcome

  • Thread-in cable routing under the top tube (and additional down tube bosses) provides plenty of mounting points for a full bolt-on frame bag

  • 6.66 pounds for the size large frame🤘

Lows
  • Dimpled chainstay and external gussets aren’t perfect, aesthetically

  • Stacked dropouts are clever, but I’d prefer a slider for easy singlespeed conversion; this would be a stellar singlespeed trail bike

  • In my experience with the SolarisMax, the dropper cable entry at the front of the seat tube isn’t ideal for a full frame bag or adjustments

  • Lower rear rack mounts would be a welcome addition; as would a bottle bracket (a la Neuhaus) on the down tube

  • Double Decker dropout is not compatible with Transmission derailleurs
