I have a chariot 2 bike trailer that mounts in the 'typical' way: an arm extends from the front left corner of the trailer and attaches to a socket joint on the left-side axle of the rear wheel on the bike. Here is a picture of the trailer:
This trailer works well for a standard bike using the axle that came with the trailer. I am now trying to mount it to an electric bike as well, which has a motor on the left-side of rear wheel that is in the way of where the trailer arm would typically go. Here is an image of the electric bike rear left side:
I think this is an old-style electric bike because the motor placement is not like many other bikes I have seen around.
How can I safely attach the the trailer to this electric bike? Some things I have considered:
Extend the rear axle away from the bike by a couple inches somehow, and attach the socket as usual. I could probably find a custom axle to do this, but that axle is already holding some weight and doubling its size may not be prudent. Plus, adding the trailer off-center like that might throw the bike balance off.
Switch the arm to the right-hand-side of the trailer and mount it to the right-side of the rear wheel. This seems possible, but the arm I have is not reversible even though there is another mounting area on the right-side of the trailer. Also, the right-hand-side of the rear wheel has the gearing system, and bike balance may also be an issue?
Abandon this idea - the electric bike is not suitable for attaching the bike trailer and any attempt to do so is unsafe or unreasonably difficult or expensive. Buy a child seat mount instead.
