FIRST IMPRESSIONS: WTB HTZ EMTB WHEELS

Beefy wheels

WTB has introduced its first ever electric bike specific wheelset called the HTZ designed to withstand the demands of full powered eMTBs. The walls of the HTZ rim are 20% thicker than WTB’s KOM Tough rims. These rims are 30mm wide internally and are tubeless-ready. These wheels are laced up with 13-gauge butted (2.3/2.0mm) spokes that are oversized at the hub.

WTB’s HTZ hubs are also beefed up with a heat-treated steel freehub body and a simultaneously engaging six-pawl freehub design for maximum strength and evenly distributed torsional forces. The outer diameter of the rear axle sleeve is increased from 15mm to 17mm to eliminate flex for better bearing life. The rear hub is still 12mm axle compatible. Finned heat sinks on the brake rotor mount are claimed to reduce heat by 10% over non-finned hubs.

These wheels cost $770 per pair or $230 front and $440 rear. They are available in 29” and mixed wheel 29/27.5” combos as well as with XD, HG, or MS driver body options. They weigh in at 1,479 grams for the rear 29”, 1,422 grams for the rear 27.5”, and 1,259 grams for the front 29” wheel.

We have been riding these wheels for a few weeks now and so far they seem to be living up to their claim of being durable. They have remained dent free and true on trails that we’ve recently broken carbon wheels on. This includes riding over our heads a bit in the bike park. Keep your eyes on the pages of Mountain Bike Action for a full long term review. Check out WTB’s website for more information.
