- Step 2: Turn bike upside-downFirstly, take all the accessories, like your pump, lights and toolkit, off your bike.
- If your bike has V brakes, now release the brake cables. Starting with the front brake, push the two brake calipers into the rim of the wheel to release the tension from the cable. Then lift the brake cable up out of the retaining clip and repeat with the rear brake cable.
- Now, to protect your grips and saddle, lay out an old towel or something similar on the ground.
- Standing beside your bike, lean over it and grip the frame with your hands - one hand on the down tube at the front and the other hand on the seat post at the rear of the frame, then lift up the bike and turn it over. It's easy to turn your bike over in one go like this.
- Next, open the quick release lever on the front wheel axle and lift the wheel out. Then remove the rear wheel - open the quick release and, as you lift up the wheel, ease the rear cassette housing out of the derailleur mechanism (the part with the two cogs).
- Step 3: Clean drive systemUsing the brush and some soapy water, start by cleaning the rear derailleur, working the brush into all the moving parts.
- Turn the pedals to move the chain round and, holding a wet soapy rag around the chain on the rear deraillear, give it a good wash down.
- Now use the brush with plenty of water to clean the chain ring (the front cog where the pedals attach). Then give it a wipe down with a dry cloth.
- Taking a wet rag, now wash the pedals and then wash the cranks (the bars that hold the pedals on).
- Finallly, clean the front gear mechanism, working the rag into all the moving parts to clean them thoroughly.
- Step 4: Wash underside of bikeStart by washing the front forks with a rag and soapy water, wiping them dry with a cloth as you go. Then, in the same way, clean the centre and rear of the frame.
- Useful tip: pressure washers are great for removing grime but don't use the ones in service stations as they often add detergents to the water which will damage your bike.
- Next, wash the handlebars with a soapy rag, paying particular attention to the brake lever and gear assembly.
- Then, using a damp rag, wash the toptube or crossbar, making sure to clean under the brake and gear cables that run down its length.
- And finally, clean the underside of the saddle.
- Step 5: Wash and remount wheelsTake a wet rag and start by cleaning the rims of the front wheel. Then give the spokes a wash down and clean the axle.
- If you have a disk brake system, use the brush to clean the brake disk rotor with soapy water.
- Now, drop the front wheel back into the forks and tighten the quick release - not too tight, not too loose.
- TIP: When you have tightened the lever to the correct pressure, the quick release will leave a mark on your palm for a few seconds.
- If you need to adjust the tension of the quick release, turn the nut on the far side of the axle clockwise to tighten it, or anticlockwise for less tension.
- Now, take the rear wheel and clean the rims, spokes, axle and rear disk rotor if you have one as you did with the front wheel.
- Clean the gear cassette on the rear wheel carefully using the bike brush - use the lever end to remove any stones between the teeth, then work the brush into the cogs, using plenty of soapy water, to remove any build up of lubricant or dirt.
- Drop the rear wheel back into the frame, eASIng the gear cassette back into the derailleur assembly, then tighten the quick release.
- Step 6: Check wheelsSpin each wheel, making sure it turns freely and that you can see it's straight.
- As the wheel rotates, hold your fingers against the rims, to feel if there are any dents or knocks on either side.
- If you have disc brakes, also check both sides of the rotors on each wheel for true, by holding your fingers against the rotor while it spins, making sure it feels smooth and straight.
- If you have V brakes watch the wheel while it's spinning, to make sure that the brake blocks do not make contact with the rims.
- To fix any problems with your wheels, you need specialist equipment, so visit your local bike shop for professional maintenance.
- Now check the spokes by turning the front wheel slowly and letting you hand fall over each spoke as the wheel rotates. Every spoke should feel taught, but if one feels sloppy it will need tightening.
- While the bike is still upside down, check the tyre pressure and that both tyres are in good condition like this one. If you find any major damage, replace the tyre before your next ride.
- For more instructions on any of these, watch Videojug's other bike films.
- Step 7: Check drive systemFirstly check both pedals by spinning them, making sure that they turn freely and that there's no noise or grinding from worn bearings. If there is, you'll need to replace the pedal unit.
- Next, turning a pedal to rotate the crank, listen out for any noise or signs of wear from the bottom bracket (the assembly that holds the cranks and chain ring in place). If you find any, it will need further maintenance.
- Now, check the front gear mechanism turn the pedal and move the chain up and down the gears using the gear lever. You're looking and listening for signs of snagging which happen when the mechanism is misaligned and needs adjusting. Now, do a similar check with the rear derailleur and gear cogs.
- WARNING: If you ride your bike with a misalinged gear mechanism or derailleur, the chain can easily jump off the cogs.
- Step 8: Wash topside of bikeNow stand by your bike and grab the frame with both hands as you did before to turn your bike back up the right way, then lean the bike against a wall.
- Using a clean rag and soapy water, wash the handlebars and the headset (the part where the handlebars meet the frame). Take care to clean well around the brake and gear levers. Then wash the tops of the forks on the front wheel and, if you have front shocks, give the Seals a good wipe down.
- Moving to the centre of the bike, clean the downtube and the top tube or crossbar.
- Now, open the quick release to remove the saddle. Wash the saddle tube and the seat post on the frame, then remount the saddle, tighten the quick release and give the saddle a wipe over.
- Finally, clean the seat stays (the two tubes that join the seat post to the rear axle) and wash around the bottom bracket.
- Step 9: Check brakesTest your brakes by standing in front your bike holding the handlebars. Apply the front brake and pull the bike towards you. The front wheel should not move at all and if you continue to pull, the rear wheel should lift up off of the ground, otherwise, the brake will need adjusting.
- Now, do the same test with the back brake. When the brake is applied, the rear wheel shouldn't turn round and if you keep pulling, it should skid. If not, the rear brake will need adjusting.
- Also, look at the brake levers - the brakes should start to grip at about 1/3 pull. The levers should not touch the handlebars. If they do, your brakes need adjusting.
- If you have disc brakes, check they are in good condition by standing in front of the bike and looking down inside the disk brake caliper (the bit that fits around the brake rotor). Apply the front brake and you should see both brake pads move across equally to clamp the rotor. If they don't, this indiCATes a problem. Repeat the above test with the rear disk brake, standing where you can see down into the rear caliper.
- If you have V brakes check the brake blocks for signs of wear. They should be free of graphite build-up, and the grooves in the pad should be deep, otherwise they'll need replacing.
- WARNING: never let you brake pads wear down to the point where they scrape the rims.
- With V brakes, also check both brake cables for signs of wear or fraying. Start at the brake levers on the handlebars. Follow the cables along the top tube, then check the other end of both cables where they meet the brake calipers. If you find any signs of wear or fraying in your brake cables, they will need replacing.
- Step 10: Check headsetStand beside your bike, and holding the headset with your left hand, apply the front brake with your right hand and rock the bike back and forth. Make sure you cannot feel any slack or hear any knocking in the headset - if you can, your headset will need adjusting.
- Step 11: Lubricate drive systemFirst place some rag over the rear wheel rims underneath the derailleur to catch any oil drips.
- Then, rotate the pedal anticlockwise to move the chain around. Holding the spray lubricant vertically, spray the chain for a few seconds as it passes over the rear gear cogs.
- Next, moving the chain with the pedal, spray the teeth on the inside of the chain ring near the cranks. Rotate the pedal again and finally, lube the outside of the chain ring in the same way.
- Step 12: Check lightsNow reattach yor lights and any other accessories you took off. Turn the front light on, making sure the light is bright, then do the same check with the back light. Don't ride with dim lights - replace the batteries if necessary.
