If your e-bike lives on a balcony, in a carport or down the side of the house, a good cover is cheap insurance. It keeps rain off the display, controls and connectors, stops the harsh Australian sun from fading paint and cracking the saddle and grips, and hides a bike worth thousands from anyone walking past. The catch is that e-bikes are bigger than ordinary bikes, and a cover sized for a road bike often won't reach over wide bars, a rear rack or a child seat. These are the covers we'd shortlist. They're researched picks based on manufacturer specs, independent reviews and owner feedback, not hands-on tests, and we've listed the size and key features of each so you can check it will fit your bike.
Quick picks
- Best overall: Oxford Aquatex Pro Single Bicycle Cover
- Best padded e-bike cover: Oxford Stormex Single E-Bike Cover
- Best budget: Puroma Bike Cover
- Best for big bikes and child seats: BikeParka XL Bike Cover
- Best for cargo and longtail e-bikes: Oxford Aquatex Pro Cargo Bicycle Cover
- Most compact: Topeak Bike Cover
Before you buy: measure your e-bike
The most common complaint about bike covers is that they don't fit. E-bikes are long, tall and often wide at the handlebars, and accessories add bulk. Before you order, grab a tape measure and check three things:
- Length. Measure from the front of the front tyre to the back of the rear tyre (or the end of the rack if it sticks out further). Most single covers suit bikes up to about 2 metres long. Longtails and cargo bikes need a cargo-size cover.
- Height. Measure from the ground to the top of the handlebars or saddle, whichever is higher. Add a bit if you have a tall stem, a phone mount or a child seat.
- Extras. Rear racks, baskets, child seats and big mirrors all need room. If you have any of these, size up.
A cover that's a little too big is fine as long as it has a strap or drawcord to stop it acting like a sail. A cover that's too small will leave the wheels and drivetrain exposed and tear at the seams.
The best e-bike covers
Oxford Aquatex Pro Single Bicycle Cover
Oxford is a long-established British maker of bike and motorbike covers, and the Aquatex Pro is its everyday outdoor bike cover. It's made from double-stitched 210D polyester with a waterproof PU coating and UV-resistant fabric, and the seams are internally bonded to keep rain out. At 210 x 80 x 110cm it's roomy enough for most single e-bikes. It also has the practical touches cheaper covers often skip: a lock hole so you can keep the bike locked while it's covered, an adjustable belly strap to stop the wind lifting it, reflective strips and a storage bag. Don't confuse it with the cheaper, non-Pro Aquatex, which independent reviewers found thin, with no straps or lock holes.
- 210D PU-coated polyester with bonded seams
- Lock hole and belly strap
- Big enough for most single e-bikes
- Easy to confuse with the thinner non-Pro version
- May be tight over a child seat or tall cargo setup
Oxford Stormex Single E-Bike Cover
The Stormex is Oxford's premium cover made specifically for e-bikes. The big difference is the inside: a soft, padded, heat-resistant lining that helps protect paint and the display from scratches and knocks, which matters if the bike is stored somewhere people squeeze past it. The outer has externally bonded seams, UV colourfast solution-dyed fibres and reflective panels, and there's an adjustable belly strap. It measures 195 x 80 x 110cm. Oxford's own advice still applies: don't put it on while the motor or brakes are hot, and keep it away from sharp edges.
- Padded, heat-resistant lining protects paint and display
- Bonded seams and UV-stable fabric
- Designed for e-bikes
- Premium price
- No lock hole listed by the retailer we checked
- Slightly shorter than the Aquatex Pro
Puroma Bike Cover
Puroma has been one of the best-selling bike cover brands on Amazon for years, and it's the pick if you want something cheap that does the basics. It's a waterproof, UV-protected polyester cover with a lock hole and a double-stitched hem, sold in sizes for one, two or three bikes. For an e-bike, choose at least the XL size, and consider the two-bike size if your bike has a rack, basket or child seat, because the extra length and height make it much easier to get on and off. The trade-off is lighter fabric than the Oxford Pro covers, so expect it to wear faster in full sun.
- Budget price
- Lock hole
- Sizes for one, two or three bikes
- Lighter fabric won't last as long outdoors
- Sizing names can be confusing, so check the dimensions
BikeParka XL Bike Cover
BikeParka's XL is built for exactly the bikes that standard covers struggle with: larger bikes, wide handlebars and bikes with child seats, and the maker markets it for e-bikes. It's 225cm long and 140cm high, suits handlebars up to 100cm wide, and is made from ripstop polyester with sealed seams, rated waterproof to 2,000mm. An adjustable sewn-in elastic and toggle snug it down, and it packs into its own stuff sack, so you can carry it on the bike. Cyclingnews noted that BikeParka's larger covers have lock access, but check the listing for your exact version.
- Fits child seats, wide bars and big frames
- Sealed seams, 2,000mm waterproof rating
- Packs small for carrying
- Mid to premium price
- Less widely stocked in Australia than Oxford
Oxford Aquatex Pro Cargo Bicycle Cover
Cargo bikes and longtails are too long for any normal cover. Oxford's cargo version uses the same 210D PU-coated, UV-resistant polyester and bonded seams as the Aquatex Pro, but adjusts from 215cm to 280cm long (80cm deep, 110cm high) to suit different cargo bike designs. It has lock holes at the front and rear, two adjustable belly straps, an elastic pull cord at the back, reflective strips and a storage bag. If your cargo bike has a tall canopy or a high kids' seat setup, check the 110cm height against your bike first.
- Adjusts from 215cm to 280cm long
- Front and rear lock holes, two belly straps
- Same tough fabric as the Aquatex Pro
- 110cm height may not clear tall cargo setups
- Overkill for a standard e-bike
Topeak Bike Cover
If you want a cover you can take with you, say for a bike parked at work or a holiday cabin, Topeak's Bike Cover is the light, packable choice. The version for 27.5-inch and 29-inch mountain bikes measures 200 x 105 x 81.3cm, weighs about 330g and folds into an attached zip pouch. Cyclingnews found it kept water out in a soak test and rated it the most commuter-friendly cover it tried. The compromises: it's a snug fit with little spare room, it has no lock holes, and Topeak says it's for storage only, not for use on car racks or public transport.
- About 330g, packs into its own pouch
- Kept water out in independent testing
- From a well-known accessories brand
- Snug fit, may not cover racks or large frames
- No lock holes
- Not for use on car racks
Buying guide: what to look for
Fabric and waterproofing
Thicker fabric lasts longer outdoors. Denier (D) is a rough guide: 210D polyester with a PU coating is a good middle ground between strength and weight, while very light "190T" covers are cheaper and pack smaller but wear out sooner. Look for sealed, taped or bonded seams, because stitched seams are where water gets in. Some brands give a waterproof rating in millimetres (a "hydrostatic head"); higher is better.
UV resistance
In most of Australia the sun does more damage to a cover than the rain. UV breaks down fabric and coatings over time, so a cheap cover left in full sun can go brittle and split within a season or two. If the bike lives outdoors, choose a cover that lists UV-resistant or solution-dyed fabric, and park it in shade where you can.
Lock holes and straps
A lock hole lets you run a chain or cable through the cover and around the frame, so you don't have to choose between covering the bike and locking it. A belly strap or drawcord matters just as much: an unsecured cover can blow off in a gusty change, or flap against the bike and scuff it. For locking advice, see our guide to the best e-bike locks in Australia.
Breathability
A fully sealed cover can trap moisture underneath, especially after a wet ride or on cool nights, and condensation is bad news for chains, bolts and electrical connectors. Let the bike dry before covering it if you can, and choose a cover with a little room to breathe rather than one stretched tight.
E-bike tip: a cover is for storage, not charging. Take the battery out and charge it inside, on a hard surface, with someone nearby, not under a cover in the carport. Our guide to e-bike battery fire safety at home has the official SA fire service advice. Also let the motor and brakes cool for a few minutes after a ride before you put a cover on, as several cover makers warn against contact with hot parts.
Does a cover help with theft?
It can. A cover hides what kind of bike is underneath, and an e-bike is a much more tempting target than an old commuter. It's not a lock, though. Pair it with a good lock and a fixed anchor point, and if you live in a unit, read our tips on stopping e-bike theft in an apartment.
FAQ
Do I need a special cover for an e-bike?
Not necessarily, but you need one big enough. E-bikes are usually longer and taller than regular bikes and often carry racks, baskets or child seats, so look for a cover at least 200cm long and 110cm high, or one sold for e-bikes or larger bikes.
Can I leave my e-bike outside with a cover?
A good cover protects against rain, dust and sun, but storing an e-bike indoors is still better for security and the battery. If it has to live outside, use a UV-resistant cover with a strap, lock the frame to something solid, and take the battery inside, especially in hot weather.
Should I take the battery off before covering my e-bike?
If the bike is stored outside, yes. It's safer to bring the battery inside, out of the heat and rain, and to charge it indoors where you can keep an eye on it. Many e-bikes also let you remove the display, which stops it being damaged or stolen.
Can I use a bike cover on a car bike rack?
Usually not. Most storage covers, including the Topeak Bike Cover, aren't designed for highway speeds and can flap, tear or blow off. Use a cover sold specifically for transport if you want to protect a bike on a car rack.
