HTZ Freehub Kit

A loaded e-bike climbing a steep, chunky fire road at a hard, steady cadence keeps the freehub under load the whole way up, and the WTB HTZ Freehub Kit is the replacement e-bike freehub body for WTB HTZ hubs that handles it. All six pawls engage at the same moment, which spreads motor and pedaling torque across the full set instead of loading a few. WTB makes the body from heat-treated steel, which the brand says resists gouging and pawl socket failure under load.

What Our Gearhead® Experts Are Saying:

“I match the hub family first, because this kit is listed for WTB HTZ hubs at 12 x 148mm and I never assume it carries over to another WTB hub. Then I match the cassette standard, HGR, XDR, or Micro Spline, since the cassette has to slide onto the body that comes out of this kit. A fresh body ends the skipping that shows up on hard climbs once a worn one starts letting go under motor power.”
