    I was just thinking, reading about e bikes- it is past time for every sidecar company, big manufacturer or small shop, to conference up and standardize a big under-floor battery pack- with standard inputs and outputs, standard sizes, tray for quick replacement, standard wiring harness, and get ahead of the game. The room and good weight placement that hacks have for batteries- it could put them ahead of bikes and cars.... think 2024, you techies.

    Problem is right now if you were going to use the typical 400 to 800 volt battery pack and propulsion system it would cost more than the whole sidecar. For folks that want to experiment, it doesn't take much of a crash to total out a Nissan Leaf EV and they sell cheap...

    I'm with Mule, what better platform than a sidecar.

    Now if you just had the technical know how for all of the controlers and 'puters that go along with it, you might not get electrocuted in you shop!

    I agree about the suitability of the sidecar platform and some of the advantages this would bring.

    Maybe the thing to actually design would be a range enhancing sidecar battery pack for electric motorcycles. Make it a leaner and it might even prove successful with the traditional two wheeled crowd...

    Reading about a discussion on strut angles ( here: Sidecar strut angles

    https://r.tapatalk.com/shareLink?sh...dex.php?threads/Sidecar-strut-angles.1382211/ )

    This threw up another question for me, are certainty types of joints better on certain mounts, I.e. Tube clamp style slip joints(? not sure that's what to call them) vs threaded eye (? clevis) or rose, ball joints??

    I suspect, experience dictates one has greater rigidity vets easier adjustability.. but on an ideal build what or rather what combination is preferable?

    I suspect the lower mounts as larger tube within tube slip/clamp style and the upper ones of an easier adjustment style but frankly I don't know so what do some of the experts think?

    Cheers,

    Rant.

    Quick ? I'm getting ready to adjust the lean out on my rig and know that when that is set correctly, I may need to adjust toe in. The question is do you measure toe in at the center of the contact patch of the front wheel or somewhere further ahead or behind.

    Thanks

    Screw type adjusters are stronger than clamp-type ones, used on the connecting arms. Rose joints and ball joints have published specs, it's easy to find the strength and recommended uses of each size and type.

    Although many of our USA sidecar mfgrs. use two male rod ends, a clevis male/female style is better as the bolt holding the two ends are in double shear rather than single shear.

    On the EZS K connections with double shear you can also adjust the toe without complete detaching the mount.
    Loosen the big nut give it a tap loosen the lock nut on your adjuster and adjust in or out. :hmmmmm:hmmmmm tighten the large nut again.

    Just in case you didn't know, the guy that wrote the article used to race off road sidecars in England, has worked on sidecars all his life, has built custom made dedicated rigs that most people could only dream of. I understand if it's all a little to technical for you.

    It's important to observe a cooling off period before jumping down somebody's throat. 10 years is about right. :lol3

    The Canooks are all getting a little grumpy these days, I guess they are about ready for spring by now.

    I'm going with trial and error. Im going to attach the suspension/axle assembly with clamps about where the conventional formula dictates. I'll throw a few hundred pounds on it and try it out. If needed I can make any adjustments until I'm happy and then weld it up. I cut and redid the rear pivot about 6 times. IMG_20190608_161741299.jpg IMG_20190608_161840384.jpg
