We're re-branding as Glow Worm Electric Bicycles

Glow Worm Electric Bicycles | E-bike Servicing and Repairs Sydney

Glow Worm Electric Bicycles in Sydney has a fully equipped mechanical workshop and offer unmatched service to everyone who owns one of our electric bicycles. Our mission is to keep your glow worm e-bike as your main mode of transport.

In some cases we can even provide a courtesy electric bike while your e-bike is in our workshop!

As of September 2019 we are exclusively servicing the electric bicycles that we sold, raising the level of service to our e-bike owners even higher with faster turnaround times and quicker bookings.

This means we are no longer accepting repair work for any non-electric bicycles or for e-bikes that we did not sell. This was not an easy decision to make and we know it will cause significant inconvenience to many of you who have been coming to our workshop for years. We do apologise - please see our FAQ for previous workshop customers here

We carry out warranty work on eZee and Bosch electric bicycles and we do not charge for labour time for e-bikes purchased from us (original owner only). Both of these systems have a 2 year warranty. 

Our workshop at any given moment is booked full, as most of our customers rely on their electric bikes for the day to day usage! And having operated this way since 2009, we now have a lot of customers and always find it challenging to fit them all in to the workshop schedule. We therefore only deal with urgent matters 'on the spot'. 
For minor repairs such as a puncture repair, it's fine to just drop in unannounced, but it's better to send an email first. If your e-bike has an electrical issue, then please call us or email describing the issue. In most cases we can get your bike seen, even if not repaired, without a formal booking. We may also be able to lend a battery or a courtesy bike or something like that. 
For all other matters, please contact us for a booking.


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
