Cycle Maintenance

The place in the app to record the work done on your bike.


Pocket CycleTech helps you track the usage of physical parts and also allows you to record when you did service tasks. When you record a service action on your bike, whether you did it or a cycle tech did, you can record replacement parts. The system can then match dates of these events to rides and give you an accurate record of the mileage and time served by components. The app also allows you to record recurring tasks so you can track the maintenance of the bike, so you can record how often you lubricate the bike, or recharge the battery, or check the wear on brakes or chain. A maintenance event always consists of an action (which is a list of tasks) but using parts is optional.

For example, a service consists of checking brakes, gears, cleaning and lubricating the bike, amongst other tasks. You can select the action "Service", and it will note those actions have been done. Having checked the brakes, you may decide to change the pads, you simply remove the old pads and add the new pads with a couple of touches. You don't need a new action of "Change pads" as it is implicit, and the system has all the information it needs to track the pad wear and tear.

Maintenance List

Listing of all work done on your bike.

This allows you to list all thework that has been done on your bike

Top tips:

  • Tap to edit the .details.
  • Summary shows parts added or removed from the bike.
  • Only tell it what you know and what you need.
  • You can go back later and change things. This is not accounting software!
  • You can add events in the distant past. So if you bought your bike 5 years ago, you can record that.
  • From the details screen you can then fit parts to your bike or remove them.
  • The app uses the dates from the maintenance event to work out how much each component has been ridden.
  • Long press on an entry gives a context menu to either amend the entry or work with parts used.

Maintenance Details

Shows what happened to a bike on a date.

Top tips:

  • Items currently on the bike are shown first.
  • Usage is based on any ride that has been done with the part fitted to the bike.
  • To keep the app easy to use, it will not stop you fitting a part onto a bike that has been fitted later to this or another bike. This screen will highlight errors where a part is on another bike at the same time which can then be easily fixed.
  • use usage information to highlight potential issues and resolutions to problems you are having on your bike.
  • Lists mechanical issues you have had in one place to highlight patterns.


  • Event date and time: the date and time of the maintenance. Use the calendar and time buttons for graphical entry, or enter according to the formatting rules for the locale set for the device.
  • Action: a summary of the service action. The app uses this to track the usage of the bike between events if the action contains tasks that are  flagged to be tracked. Use the Maintain Action command to amend these actions.
  • Cycle: The cycle which has been maintained.
  • Notes: Any comments you wish to make. For example, you can use this to note chain wear.

Add/Remove Parts

Use this screen to record parts added or removed during a maintenance event

Top tips:

  • Add parts before this screen by using the My Parts option from the main menu or by the selecting Create Item command, adding any parts and then returning to the screen..
  • Your parts are grouped by part category. As there are quite a list, only existing categories are shown.
  • Parts can be added to the bike simply by clicking on the part, and removed the same way. 
  • The screen shows items that are added, items unaffected, and items removed.

Note: to keep the system easy to use, the system allows you to add or remove parts at any time in the past. This does mean that there are a couple of scenarios which are difficult to handle. Say you had a derailleur on your bike which you had scavanged from another bike. You added it to the current bike but then realised it was not showing its true wear and tear as it had been on another bike which you had records for. So if you then add the derailleur to the old bike in the past, PocketCycleTech will then have a part on two bikes. It will allow you to do this, but it will warn you that it is nonsense. You can then fix the issue by adding another maintenance event to take the part off the original bike before it is used on the current bike.

A second difficult scenario is that you realise that you made a mistake and wanted to show a part was added at a different time, but you already have a record of removing it from the bike. The app will allow you to cancel the addition of the part, and will prompt you to delete the part removal at the future event.

If you get the parts in a mess, not to worry, simply correct the events to how things actually happened and the app will be fine. Use the item usage screen to check for any errors.

Action Maintenance

Use this screen to create new actions you are interested in, and to set trackable tasks.

Top tips:

  • Actions are collections of tasks that you want to track.
  • You do not need specific actions to record part changes.
  • A task can appear in many actions.
  • Use the menu to add and remove tasks.
  • Tasks can be trackable or not and can be flipped off and on as required. As the display of tracked information is dynamic, you can look back at past task detail, even if they were not originally tracked.
