Threads on to the axle of Trek and Electra bikes fitted with a Hyena hub motor, so a hitch-mounted trailer can attach where the motor hub has no thru-axle to adapt.

Compatibility & fit

Fits Trek and Electra bikes with a Hyena hub motor. Works with any hitch-mounted trailer with two wheels and a single point of attachment - Thule, Chariot, Burley and similar. Confirm your hub against Robert Axle Project's Axle Finder, or have the Tune workshop check it.

Robert Axle Project's lifetime warranty covers defects in material and workmanship to the original purchaser, for the lifetime of ownership - it excludes misuse, neglect, improper installation or maintenance, accident damage and normal wear and tear. For warranty support, return the product to Tune Cycles and we'll manage the claim with Robert Axle Project's Australian distributor. This is in addition to your rights under the Australian Consumer Law, so keep your proof of purchase.
