Glow Worm Bicycles | Bicycle Servicing and Repairs Sydney

Glow Worm Bicycles has a fully equipped mechanical workshop and carries out quality servicing and repairs on a wide range of bikes, electric and otherwise. You're very welcome to visit with any type of bike for a quote on repairs. We love bicycles but we are not snobs and although we can't fix every type of bike out there, you'll be treated warmly and respectfully regardless of what type or condition of bike you bring in! Our workshop is focused on repairing bikes and won't try to push you into purchasing a new bicycle.

Generally there is no need to book in a repair, it is okay to just show up with the bike. You'll be able to talk to one of our mechanics about what you'd like done on your bicycle. However, our workshop is often booked about a week in advance, and if you want to minimize you time off the bike you can book a service over the phone. Keep in mind that you will need to find a time you can leave the bike with us for a whole working day.


At Glow Worm Bicycles, quotes are always free of charge, however, we don't generally do quotes on the spot. We can give you a rough idea of the possible price, but we need more time to provide an accurate quote. We quote most of our jobs over the phone, but you can arrange to receive an email quote instead if you prefer.

Quick Tune-up   $69 

Sometimes you want your bike to be brought up to optimal order before it really needs a thorough service. The tune-up is appropriate for bikes that are generally in good condition but have some small issues to sort out. Perhaps it hasn't been ridden in a while but has been stored indoors and you just want it cleaned up and checked over to be sure that it's safe and functioning well when you get back on the roads. As a guide, if your bike needs new parts then it needs more than a tune-up. The Tune-up includes:

  • Brake service
  • Gear service
  • Minor wheel true (wheels stay on bike while being trued)
  • Lube chain
  • Safety check
  • Pump tyres to correct pressure

General Service   $119

-For Electric Bicycle $139

-For Cargo Bicycles $169  

The price for electric an cargo bikes are for the same service, but adjusted for the additional challenges of servicing large, heavy and more complex bicycles. 
We apologise for any inconvenience. 


The General Service is recommended about 2-3 months after purchasing a new bike, and 1-3 times a year after that depending how you're using your bike. It will have the bike running safely and smoothly, with the brakes and gears working at their best as well as increasing the longevity of the bike and wheels.

The General Service includes the following:

  • Safety check
  • Straighten derailleur hanger and tune gears
  • Adjust/tighten brakes
  • Lubricate brake and gear cables
  • True wheels on truing stand
  • Wipe down and Lubricate chain
  • Check tightness of all bolts and screws
  • Wipe down bike
  • Pump tyres to correct pressure
  • That little something that you can't get at home


The service price does not include the cost of any parts needed, or the labour for installing them. For example if a bicycle needs a new gear cable, the price will be $119 + the price of the cable ($8) + the labour for install ($5) = $132. If however a whole gear shifter needs replacing the price will be $119 + the price of the gear shifter (let's say $25) + labour for installing the gear shifter ($10) = $154. The service also does not include any repairs or servicing of electrical systems or mechanical systems not detailed above, such as suspension fork servicing or repairing connections on an E-bike.

    Hourly Charges

    Some repairs cannot have a standard labour charge as they are inconsistent in the amount of time they take to complete-but don't worry! We are still committed to providing quotes. If a quote includes an hourly labour charge, that is the MAXIMUM charge. You will not be charged more without consultation, but the charge may be reduced if the job took less time to complete. 

    Things such as repairing a electrical motor with a broken gear, soldering or crimping new connections or converting a bike to electric are all charged as electrical labour at $150 an hour. 

    Similarly, Mechanical jobs such as bare frame bike builds, removing stuck or damaged components and any non-standard jobs are charged as mechanical labour at $100 an hour

    Poor quality bicycles

    We don't enjoy telling people that their bicycle is not worth servicing, but we also don't enjoy servicing very poor quality bikes. They take much longer to service, with unsatisfactory results. This puts both us and the customer in a bad situation where the bike hasn't improved enough to justify the repair bill but we've still worked on it for an amount of time that requires payment. Unfortunately we have to have a policy on bikes below a certain quality level to keep everyone happy. Quality is of course subjective but generally bicycles bought from supermarkets or new bikes bought for a steal online fall into our category of "poor quality bicycles". Please do not be offended by our policy, we understand that people often buy these bikes with the best intentions but that doesn't change the reality of working on the bike. Our policy for these bikes is that we only carry out the following services and repairs: - We can build the bicycle from the box (it won't be perfect!) - Replace innertubes, tyres and wheels - Replace chain - Tighten headset - Install basic parts and accessories such as racks, baskets, grips, pedals.  


    Here is a list of bicycle care procedures anyone can do at home, designed to be as simple and straight to the point as possible. These procedures are in addition to periodical servicing by a bicycle mechanic. 

    1) Keep tyres at correct pressure. Do this weekly, or if you're fanatical and have high pressure tyres, daily

    • A floor pump with a pressure gauge is much easier for this than a handpump. (Hand-held pumps are better suited to carrying with you when cycling for emergencies or long rides.) Make sure your pump can be used with the type of valve you have on your tube. Most new pumps can be used on both of the main types: the Schrader (also called the American valve, used also on car tyres) and the Presta (Also called French valve, high-pressure valve or skinny valve). We sell presta-schrader adaptors for $3 to let you pump your tyres up with conventional or even service station pumps, but it's not an ideal strategy - a good bicycle pump is the best way to go.

    • Remove the plastic valve cap. The Presta valve needs to have the metal tip unscrewed to pump. Keep the flap on the pump head down and push head down over the valve, then lift flap to lock the head onto the valve. Then pump away. For a Presta valve, screw the tip back in all the way after pumping.

    • Your tyres will typically have a minimum and maximum recommended pressure written on the sidewall. Generally pump toward the higher end of this range.

    • Benefits of keeping tyres pumped   

    • A much faster ride. Every bit of pressure reduces rolling resistance

    • Reduces wear and damage to rim, tube and tyre

    2) Keep chain lubricated. Do this at least 1-2 times monthly, or more often if you have been riding on wet days or using a light lubricant.

    • Do not use WD40 as a lubricant. a degreaser can be used to clean the chain when it is filthy, but a lubricant should still be used afterward.

    • The easiest thing to do is get an all-rounder lube from a bicycle store. Apply lube to the chain while rotating the pedals backwards with one hand until the entire chain has been lubed. Try to get every link, but don't overdo it. Run the bike through all the gears, front and back. Wait 5 minutes then hold a rag around the chain with one hand applying light pressure, and rotate the pedals with the other hand. This is to wipe away excess oil which will only attract dust and dirt. 

    • Benefits of keeping chain lubricated

    • Drastically reduces wear on chain, sprockets and derailleur

    • Makes for a smoother, faster, quieter ride

    3) Tighten brakes

    • Most braking systems come with 'barrel adjusters' located where the cable enters the brake lever. These are designed for quick and easy adjustment of the brakes as cables stretch and brake pads wear down. If your brakes feel a little loose, you can unscrew the barrel adjuster by turning it anti-clockwise with your fingers. Unscrewing it too much will result in the brake pads rubbing against your wheel, and also be careful not to unscrew the adjuster all the way out. Secure the position of the adjuster by screwing in the locking nut clockwise all the way. If the adjusters have reached their limit and the brakes are still not tight, it's time for a brake service at your local bike shop.

    4) Storage and inspection
