I promised ckndave the beginning of a reminder list of things to do to keep an ezip happy.
Here's a beginning, additions more than welcome. As more reminders are posted I'll edit them into this list so that they'll all be in one place.

Tips for CKnDave

Lots of little things, no particular order:

Charge batteries for 8 hours (as an aim) immediately after use

After 'vacation' top them off for 3 or 4 hrs

As has been said be sure batteries are locked in. Push down on battery if necessary to lock

Check the tires for embedded stones particularly after riding on gravel or freshly “Oiled and Stoned” roads, remove any stones, glass etc

Make sure, once a week that tires have 60 psi

Make sure brakes aren’t dragging. Lift a wheel off the ground, listen, observe how long it spins. If one side drags, adjust return spring tension.

Make sure than when the brakes are on HARD that there is still space between lever and handlebar or adjust cable

Make sure all of the brake mounting hardware is secure

Make sure the stem tightening bolt is tight enough that the handlebar can’t be turned while holding the wheel with legs

Oil both chains regularly, wk or so depending on weather

Make sure motor chain is properly tightened per owner’s manual

Make sure all nuts bolts on the battery rack and motor are tight

Adjust the nut on the seat quick release so the lever is hard to move when pointed directly away from the bike and takes real muscle to push the rest of the way back

Check spokes for tightness, yearly, make uniform corrections

Insurance: Record serial number, take pictures of any additions (extra chargers), save receipts

Tools:
To carry: eZip wrenches: Allen, 13/15mm flat wrench
Adjustable wrench, 17 mm cone wrench (to loosen motor mount from axle), Tube patch kit
Spoke wrench (correct size or multi), Tire irons, Bike multitool (like Topeak), Multitool with pliers like Leatherman

To have: Chain buster, crank puller, Park Tool BBT32 Bottom Bracket Cartridge Tool, the only one I’ve found to work with unique Currie Bottom Bracket Cartridge

Extra stuff to carry for longer trips: Extra tube, wire ties, small roll electrical tape, outlet checker, sunscreen, space blanket, velcro strap to clamp brake lever as a parking brake

Be sure to have extra 40 amp fuses, just in case

An extra controller might not be a bad idea if you don't want to miss a week or two

Have a plan to get your bike and yourself home if you should have a flat rear tire

Attach a blinkey butt light to the back of the rack in case your commute home runs late

A helmet light is good to have, works as a flashlight too
