A bolt-on spider, bashguard and 34-tooth chainring built specifically for eBikes running a DJI Avinox motor, giving the motor case and chainring real protection from rock strikes and kerb hits.

Highlights

• 104BCD spider splined to the DJI Avinox motor output shaft
• 34T narrow-wide chainring in 7075 aluminium with e*thirteen's M4 tooth profile
• Composite bashguard shields the chainring and motor case from impacts
• 55mm chainline, 8mm offset — set for the Avinox's output position
• Compatible with Shimano, SRAM (including T-Type) and TRP 11/12-speed drivetrains
• Includes chainring, spider, bashguard, bolts and nuts

Built for Avinox-equipped eBikes

DJI's Avinox motor doesn't have the ISCG mounting tabs that most mid-drive eBike motors use for a bashguard, so e*thirteen built this spider to bolt straight to the motor's own output shaft. It keeps the chainring, motor case and surrounding frame protected from rock strikes without adding a separate mount.

Compatibility & fit

Fits eBikes with a DJI Avinox mid-drive motor only — the spider's offset and splines are motor-specific, so it won't fit a Bosch, Shimano STEPS, Brose, TQ or Fazua motor. 34T is the only tooth count e*thirteen offers for the Avinox version. Chain compatible with Shimano, SRAM (including T-Type) and TRP 11- and 12-speed chains.
