Waterproof E-Bike Covers for Electric Bikes

An e-bike costs more than most bicycles, and it usually lives outside: in the garden, down the side of the house, in a bike rack at work. Rain on its own won't ruin one overnight. Months of it will, working its way into the battery contacts, the display, the motor seals and the chain. A waterproof e-bike cover is the cheapest way to stop that happening.
BikeParka makes waterproof covers for every shape of electric bike, from e-hybrids and e-MTBs to longtail and front-loader e-cargo bikes. Every one is seam-sealed ripstop, PFAS-free and packs into a small Stuff Sac.
Which electric bike cover do I need?
Choose by the shape of the bike rather than the motor. An e-hybrid takes the same cover as a hybrid, and the handlebar width is usually what decides it.
| Your e-bike | Key limit | Cover |
|---|---|---|
| E-hybrids, e-city and e-commuter bikes, and other standard e-bikes | Handlebars up to 63cm | STASH or URBAN (URBAN has lock-through panels) |
| E-MTBs, bulkier e-bikes with wide or high bars, or a standard e-bike carrying a rear child seat | Handlebars up to 100cm | XL / MTB |
| Longtail e-bikes with no child seats fitted | Up to approx. 210cm long, bars up to approx. 80cm | Longtail |
| Longtail e-bikes with rear child seats fitted | Up to approx. 210cm long, bars up to approx. 80cm | Longtail WS |
| Front-loader and box e-cargo bikes | Handlebars up to 120cm | Cargo |
If your bike sits close to a limit, or carries a big front basket, a child seat or a tall cockpit, size up. A slightly generous cover cinches down with the toggles; a slightly tight one never quite works. Not sure? Find Your Fit searches our database of around 979 bike models by make and model.
How to measure your e-bike for a cover
- Handlebar width: end to end, including the grips. This is the measurement that most often decides the size.
- Length: front tyre to back tyre, including a rear rack, deck or front box.
- Height: ground to the highest point, usually the handlebars, the saddle or a child seat.
Measure with any mirrors, baskets or phone mounts you leave on the bike, because the cover has to go over them too.
Why an e-bike that lives outside needs a cover

Modern e-bikes are built to be ridden in the rain, and a wet ride is not the problem. The damage comes from standing wet day after day, where rain, road salt and damp never get the chance to dry out.
- Battery contacts and connectors. Terminals and plugs are bare metal, and bare metal left damp is where corrosion starts.
- Display and controls. Handlebar displays and remotes are built to shrug off a wet ride. Keeping them out of the weather between rides is simply kinder to them.
- Drivetrain. Chains, cassettes and derailleurs are the first parts to rust on a bike parked outside, and they are expensive to replace on an e-bike.
- Cables and brakes. Water sitting in cable housings and around disc brakes is what leads to seized cables and noisy brakes.
A fitted cover keeps all of that dry for the 23 hours a day the bike is parked. Our guide to storing a bike outside covers the rest: getting it off the ground, locking it to something fixed and picking a sheltered spot.
Looking after an e-bike stored outside
- Charge indoors. Never charge under a cover. If the battery is removable, bring it inside to charge, and keep it indoors in freezing weather. Your manual gives the temperature range it should be charged and stored in.
- Let it drip first. After a wet ride, give the bike a few minutes before covering it. A cover keeps rain off; it cannot dry a bike that went under soaking wet.
- Keep the chain oiled. Wipe and re-lube after a wet week. That, plus a cover, prevents most of the rust you see on bikes kept outside.
- Lock it properly. The URBAN has lock-through panels, and the Longtail, Longtail WS and Cargo have lock-through slots, so the lock goes through the cover and around the bike. The STASH and XL / MTB have none: lock the bike as normal and fit the cover over it.

What the reviewers said
Bicycling named BikeParka its Best Overall Bike Cover, Cyclist named the STASH Best Bike Cover in its 2026 guide, and Cyclingnews made it a top pick and best for commuters. Bicycling also picked out why it suits bikes kept outside: "Unlike many designs, the Bike Parka is breathable, which helps reduce corrosion and mildew."
E-bike cover questions
Which cover do I need for my e-bike?
It depends on the shape of the bike, not the motor. Standard e-bikes with handlebars up to 63cm use the STASH or URBAN. E-MTBs and bulkier e-bikes use the XL / MTB, which takes handlebars up to 100cm. Longtail e-bikes use the Longtail, or the Longtail WS if child seats are fitted. Front-loader e-cargo bikes use the Cargo.
Is a BikeParka safe to use on an electric bike?
Yes. It keeps rain and road dirt off the battery, motor, display and connectors while the bike is parked. Do not charge the battery while the bike is fully covered.
Can I charge my e-bike with the cover on?
No. Take the cover off, or take the battery out and charge it indoors. If the battery is removable, charging it inside is the simplest habit to get into, and your manufacturer's manual gives the temperature range it should be charged in.
Which cover fits an e-MTB?
The XL / MTB. It is cut for mountain bikes, e-MTBs and wide-handlebar bikes with handlebars up to 100cm.
Can I lock my e-bike through the cover?
On the URBAN, yes: it has lock-through panels so a lock passes through the cover and around the bike. The Longtail, Longtail WS and Cargo have lock-through slots. The STASH and XL / MTB have none, so lock the bike as normal and fit the cover over it.
Do you make a cover for longtail or cargo e-bikes?
Yes. Longtail e-bikes such as the Tern GSD or RadWagon use the Longtail, or the Longtail WS if rear child seats are fitted. Front-loader e-cargo bikes such as the Urban Arrow or Riese & Müller Load use the Cargo.
Do you make a cover for folding e-bikes?
Not specifically. Our covers are cut for full-size bikes, so send us your bike's measurements before ordering and we will tell you honestly whether one works.
Will moisture get trapped under the cover?
Not if the bike is reasonably dry when you cover it. BikeParka covers are elasticated at the wheels rather than sealed to the ground, so air moves underneath and condensation vents away. A sealed plastic sheet is what traps water against a bike.
Keep your bike snug, dry and clean.
