🛞 Replacing the Tire on Your Front Hub Motor Kit
Every front hub kit arrives with a heavy-duty, puncture-resistant Maxxis Pace hybrid tire already mounted — for most riders there's nothing to do. If you want to change it (for example, a narrower tire on a road frame, or a knobbier tire for trails), here are the rim specs you'll need to choose a compatible replacement.
Our front-hub rim specs:
- Inner width (between the rim hooks): 18.8mm
- Outer width: 24mm
- Included Maxxis Pace tire sits ~42mm across
- Smallest tire we've found that works: about 25mm — go narrower than that and the tire may not seat safely on the rim
- Match the tire to your wheel size (26" / 27.5" / 29" — printed on the current tire and rim).
- Use a tire-to-rim compatibility chart (WTB publishes a good one) to confirm your intended tire width is rated for an ~18–19mm internal rim.
- When in doubt, have a local bike shop confirm the pairing — they can check seating and clearance for your fork.
