E-bikes add more to the trail-riding experience—more distance, more laps, more climbs, more descents—and the WTB HTZ i30 rim is built to be burlier to combat the additional wear and tear of that more.


  • With the thickest rim walls WTB offers, proven I-Beam center support and asymmetrical spoke hole drilling, this a great choice for your e-assist trail, enduro or downhill bike
  • Most trail and enduro tires are designed to be installed on a 30 mm rim; doing so will optimize the air volume, sidewall support and tire profile of those tires
  • Increased wall thickness is capable of withstanding the forces of a modern e-bike
  • Vertical support within the inner rim cavity drastically increases the strength and rigidity
  • The additional reinforcement counteracts spoke loads and provides lateral rigidity, which is increasingly important for e-bike rims
  • Durable nylon TCS Solid Strip lies between the rim and tubeless tape to prevent the tape from pushing into the spoke holes, ensuring a smooth interface between tire and rim
  • The smooth surface makes it easier to mount a tire by preventing air from escaping around the bead at each indent during inflation
  • Solid Strip also protects the airtight system from puncture in the case of a broken spoke
  • 6069 aluminum alloy is excellent at absorbing massive impacts, so you don't have to compensate for the additional weight of e-bikes with high tire pressures
  • Designed for use with disc brakes
