List of Common Bike Problems

This section provides an index of issues described by non-technical jargon to help you identify the problem with your bike and find a solution! The severity of items listed here goes from:

Difficulty

  1. EASY - Easily repaired with basic tools
  2. BASIC - You can follow a guide and repair it with instructions and basic tools
  3. INTERMEDIATE - Requires some generic tools that come with some repair kits, and understanding to repair
  4. ADVANCED - Requires tools that aren't normally provided in repair kits and a good knowledge of bike functioning to repair.
  5. EXPERIENCED- Requires specific tools and knowledge to resolve and will probably take a while (why not consider sharing tools in your neighbourhood?)

Severity

  1. LOW - You can ride on this for a while without problems
  2. MEDIUM-LOW - It'll get worse, but not really a big issue
  3. MEDIUM - It will get worse, and could lead to more repairs in the future
  4. HIGH - Repair very soon - fix it so you can ride home, but don't ride it again
  5. SEVERE - You need to repair this immediately, and it'd be dangerous to ride while in this condition.
