You can tell a lot about a man about how he handles times of tribulation and challenge on his rides. Here is a write up on how different writers of electricbike.com prepare for the inevitable break downs and let downs that electric bike riding inevitably brings.

Dogman’s Emergency Repair Kit:

If you are riding a distance longer than you want to push a bike home
with a flat, you need a survival kit. This is my emergency toolbox. It’s very
complete because sometimes I go on weekend rides of more than 50 miles.
Not shown is a large quantity of chunky 4×4 grade slime in the extra thick
tubes on the bike. I carry a wrench for removing the motor wheel, tire irons,
patches, a new thin tube, and a tire pump. Other repairs might be splicing
a wire, so tape, and a small knife in the tiny multi tool. Chain breaker
will save you if you ruin a chain. Zip ties could save you in many ways,
including clothing malfunctions. Allen wrenches and hex wrenches in the
bike multi tool. The plug adapter can be needed if you are charging out on
the road and the plug is an old fasioned ungrounded one. Huge plastic bags
can be raingear or a tent for the bike if needed. Carry a voltmeter if you
don’t have one built into the bike. I have a cycleanalyst on my bike.

Deerfencer’s Emergency Repair Kit

I have a dedicated fanny pack for this strapped
on top of my battery packs on my rear rack. In it you’ll find about
(4) CO2 cannisters and an applicator (I don’t bother carrying a
pump–too old school and bulky), spare tube, rim tape, tire patch kit,
extra chain links, spoke wrench, allen wrenches, screwdrivers,
electrical tape, some spare 10-12 gauge insulated wire for emergency
electrical repairs, wire nuts for same, an electrical
crimper/stripper/cutter, and an emergency ID card.

Roger Recumbents Emergency Repair Kit:

I really don’t have much besides a couple tubes, a small pump, some tire irons, and a big 21mm wrench to get the front wheel off if necessary.  Boring!  However it’s better than before, which was nothing.

Cell phones are nice pieces of equipment!

 

Green Machine’s Emergency Repair Kit

no room left for survival equipment

Cell phone, folding cash, 2 friends with trucks I can possibly call in a jam, a minivan  at home with a hidden key, a flask of rye whiskey and a Patagonia sweater jacket in case it gets dark…and  a hammock (stuffs to the size of a grapefruit) and some hammock straps. The hammock straps are great because I usually ride with a friend and the straps double as tow straps. Also when you ride with friends, if one bike breaks the other person can go back and get the van.  Also in San Francisco  we have a good public transport system, and buses have bicycle carry racks robust enough for an electric bike.
