Axle Nut Wrench Set — 15 / 18 / 19 mm

Hub motors use large axle nuts that a normal bike multitool cannot turn.

Hub-drive e-bikes secure the motor axle with heavy metric nuts — usually 15 mm, sometimes 18 or 19 mm. Quick-release skewers and folding multitools are useless here.

• Box-end wrenches in all three common sizes
• Long handle for the torque these nuts need

Required for any motor or rear wheel replacement.
