Electric Bike Emergency Repair Kits

July 20, 2012

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.


Eric has been involved in the electric bike industry since 2002 when he started a 6000 square foot brick and mortar Electric Bike store in downtown San Francisco. He is a true believer that small electric vehicles can change the way we operate and the way we think.


  1. I ride solely in urban areas so I carry two things for emergency: iphone with Cabulous app, and cab fair. My Prodeco e-bike folds so if I have a problem and can’t reach a friend for a lift, a cab ride is all I need. =)

  2. This bike I what ride it and to have fun with it and take care fo it and if you what me to buy it or free to ride it to trips if need to and for the speed going to me cool to have fun with it if you what buy it and send it to my e-mail if you what I gave it to you now my e-mail is d.woodson1@yahoo.com

  3. I recently resurrected my Wave Crest Tidal Force after 10 years. To my joy it was just a bad corroded connection in the battery cable. I rode it happily for two days, and then after a 10 mile ride by pedal power alone, the rear wheel motor seized up with horrible grinding noises. I thought that I toasted the wheel bearings. After a long push home, (I could not even pedal it in manual mode), I opened up the rear wheel to find that all the metal clips that hold some electrodes in place had rusted, split in two, and where getting caught in between the rotary magnets and electro magnets. I disassembled and cleaned the corrosion, dust, and rust out of every magnet and part. The sealed bearing was indeed rusted but still functional, but I destroyed it trying to pry apart the cover plate. I accidentally broke one of the arc magnets in half while I was cleaning them. It reconnected with the other magnets with too much force and snapped in two. My ebike bubble has been once again deflated and I am left to store the parts in my garage once again in hopes that I can find a used Tidal Force motor for parts or a replacement at a very low cost. I’m bummed that the great design and technology used faulty metal clips that messed everything up and made my initial $2000+ investment a worthless cause once again. It would be the coolest thing if this product was really built to last and durable enough for the military, because it was really fun to ride 25mph+ with little pedaling effort up hills. Does any one have a connection to old WaveCrest Tidal Force motor parts? Thanks

  4. is like everything else u have 2 prevent

  5. We just purchased our first eBikes- do you know if there is a portable battery that would work for emergency charge?
