Spokes

Spokes join the hub to the rim and carry your weight and, on a hub motor wheel, the motor's torque. Replacements must match your wheel's gauge, length and nipples.

Spokes are the thin steel rods that join the hub to the rim. They hold the wheel round and straight, carry the rider's weight and, on a hub motor wheel, pass the motor's pull to the rim. One broken or loose spoke lets the wheel wobble and puts extra load on the spokes around it.

What it's used for

Replace a spoke that has snapped, bent or come loose at the nipple, then bring the wheel back to true. Work through Check spokes and wheel true first, since a loose spoke can often be tightened instead. On a rear motor wheel you may need to take the wheel off first, as in Fix a flat on a rear hub motor wheel.

What to look for

  • Gauge (thickness). Grin Technologies notes that hub motor wheels usually come with 13 gauge spokes while bike shops tend to stock 14 gauge, and it suggests butted spokes that are 13 gauge at the hub end and taper to 14 gauge at the threads (Grin wheel building guide). Don't assume your bike follows that pattern. Check it.
  • Your model's numbers. Lectric says the XP uses 12 gauge stainless spokes, 2.6 mm thick, with a 4.2 mm nipple, tensioned to 50 to 80 kgf (Lectric help center). Tenways publishes specs per model. On its CGO600, for example, the front spokes are 14G at 2.0 mm and the rear spokes are 13G at 2.2 mm, with different lengths per side (Tenways spoke specs).
  • Exact length and position. Length depends on the hub, rim and lacing, and hub motor flanges are much larger than a normal hub's, which changes the lacing (Grin). Aventon sells OEM sets of six spokes and nipples that you pick by bike model and spoke position (Aventon spoke set). Velowave sells front and rear packs per model (Velowave spokes).
  • Matching nipples. Aventon sells nipples in 12 and 13 gauge (Aventon nipples). Grin warns that thicker spokes need larger rim holes, and that reducing nipples used to fit them to standard rims become the weak point (Grin).
  • Kit wheels. E-BikeKit sells 12 gauge spokes, butted to 13 gauge at the threads, cut for its own rims and motors, and says they may not fit other wheels (E-BikeKit spokes).
  • Measure if unsure. Park Tool measures spoke thickness at the middle of the spoke with calipers or a gauge (Park Tool tension guide). Tension targets vary by rim, so use your maker's number where it gives one.

Typical price

  • Velowave lists spoke packs for its own bikes from $15 for the Spirit to $29 for the Ranger, with the Ghost rear pack at $22 shown sold out (read Nov 9, 2026) (Velowave).
  • E-BikeKit lists its 12 gauge spoke with nipple at $2.00 each, with every length shown sold out (read Nov 9, 2026) (E-BikeKit).

Where to buy

  1. Your bike maker's parts store or support team, for example Aventon or Velowave.
  2. The kit or motor maker, if your wheel came in a kit, such as E-BikeKit.
  3. Independent specialists in Where to buy e-bike repair parts.
  4. A local shop, through find a shop. Several broken spokes, a cracked rim or a motor wheel that won't true are shop jobs.
