Introduction
As a mechanic, I will get booked to spend a day at a workplace checking and making basic adjustments to employees' bikes.I usually encounter bikes where all I need to do are some basic adjustments to transform their performance, making it easier and safer for the owner to ride.
In my opinion, every bike owner should be able to do some very basic checks and adjustments to maintain their bike's performance and safety.
Below is a guide on the checks that you should regularly carry out on your bike.Some of them you should do before every ride (e.g., brakes). Others at least once a week (e.g., checking tyre pressures).
The good thing about these checks and adjustments is that the are as easy as ABC.
The ABC Bike Safety Check
This process of checking your bike is based on the one devised by cycle trainers to teach to theirs students as part of the essential pre-ride checks that every rider should carry out.
The trainer's check list only covers ABC which stands for Air, Brakes and Chain. It has been expanded to include D = Direction, E= Elevation, G= Grime Gleam and Glide and F= Frame, Fastners and Fixtures.
Below I will explain the check list in more detail.
A = Air
This means that you should check to see if your tyres are inflated. You should squeeze your tyres and as a rule of thumb your tyres should be as firm as an apple and not as soft as an over ripe banana.
If your tyres are soft you should pump them up before your ride. You should check the condition of the tyre. Is there any glass or flint embeded in the tread?
Are there any crack in the sidewall?
Once your are satisfied with the tyre pressure( I will go into greater detail in a later blog) you should check the wheel. Check to see that he wheel is securely mounted in the frame front and rear.
Check that the wheel is spinning freely and check for any broken spokes.
Starting at the valve, squeeze the spokes in pairs. A broken spoke will be very loose and it should be replaced asap.
B = Brakes
For me the brakes are the most the most essential part of the bike. If they are not capable of stopping you, the bike should not be ridden.
You should check your brakes in the following way (this method is suitable for all types of brakes).
The Front Brake
With your hands on the handle bars and over the front brake lever push the bike forward and pull on the lever. If the brakes are functioning properly the rear wheel should lift off the ground and the brake lever should not touch the bars.
The Rear Brake
With your hands on the handle bars and over the rear brake lever pull the bike backwards and pull on the lever. If the brakes are functioning properly the front wheel should lift off the ground and the brake lever should not touch the bars.
If you brakes do not function in the way described above you should get them adjusted by an experienced mechanic. The adjustment might also involve having to change brake pads. You should never ride your bike with poorly functioning brakes.
C= Chain
This means checking the drivetrain. The drivetrain, which includes the chain, gears, and pedals. Look for any rust on the chain, ensure that it is lubricated but not over lubricated (too much oil is just as bad as too little). Also examine the chain for wear with a tool called a cahinwear gauge. There are many different makes and price ranges here is one made by Park Tools
You shouhld have one as you need to check on your chain's wear.
Check to see how your gears are cahnging.
And finally check that the pedals spin smoothly. Check the bottom bracket: Wiggle the cranks side to side. There should be no play or looseness. Check the pedals: Make sure they spin freely and are not loose.
D= Direction
Handlebars, Stem and Steering
Test the handlebars: Ensure they are aligned correctly and not loose. Apply pressure to make sure they don’t move out of place.
Inspect the grips or tape: Check for any wear or looseness.
Check the brake levers and shifters: Make sure they are securely attached and functioning properly. Also check that phone/computer holders are secure.
E = Elevevation
Check the saddle height and alignment: Ensure the saddle is at the correct height and aligned straight. Check for any rough edges on the saddle.
Inspect the seat post: Ensure it is properly secured and not slipping. Loosen the seatpost clamp bolt and check to see if you can twist the seat post.
F= Frame Fixtures and Fasteners
Inspect the frame and fork: Look for any cracks, dents, or signs of stress, particularly around welds and joints.
Fixtures: Make sure racks mudguards etc. are sercurely fastened to the bike.
Fasteners: Check that all nuts and bolts are tightened. If you have any bottle any bottle cage bolts missing replace them.
G= Grime Gleam and Glide
Is your bike dirty? Then clean it! A clean bike is a mean bike.

Conclusion
By incorporating the ABC Check into your routine maintenance schedule, you can catch potential issues early and address them before they escalate into significant problems.
Safety should always be a top priority when cycling, and a well-maintained bike is essential for a smooth and enjoyable ride.
If you ever encounter any issues beyond your expertise when carrying out the ABC Check , don't hesitate to seek professional assistance. A bike shop or mechanic can provide a thorough inspection and service to keep your bike in top shape for all your cycling needs.
Remember, proper maintenance not only ensures your safety but also prolongs the life of your bike, allowing you to continue enjoying the benefits of cycling for years to come.
Make the ABC Check a habit, stay safe on the roads, and ride with confidence and peace of mind. Rides become even more enjoyable when you know your bike is in top condition.
