Douche portable pour VTT et motos tout-terrain

Keep a filled portable pressurised shower in the boot and you can rinse the bike at the trailhead, in the car park or at the lay by before it goes anywhere near the car. The NewFlow 8 Litre Portable Showeris hand pumped, so there's no need for a tap, a hose or a power supply. Fill it at home or from a stream, pump it up and use the jet mode to blast mud from the frame, wheels and drivetrain while it's still wet and easy to shift. Dried on trail mud is far harder to remove later, so a two minute rinse at the trail saves a long clean at home.

Not really, which is why most bike brands and mechanics advise against it. A pressure washer forces water and grit past the seals on your bottom bracket, headset, hubs, pivot bearings and suspension, washing out grease and shortening the life of expensive parts. A portable pressurised shower gives you enough pressure to lift mud without driving water into bearings. Use the jet mode on the frame and tyres, drop to a gentler setting around suspension seals, pivots and hubs, and spray at an angle rather than straight into the bearings. Dry the chain and lube it afterwards.

A proper rinse of a muddy mountain bike takes roughly 4 to 8 litres, so one tank of a NewFlow shower will clean one filthy bike or give two moderately muddy bikes a good going over. Because water only flows when you press the head, you use far less than a hose left running. Start with the worst of it, the tyres and the down tube, then work through the drivetrain, and finish with a gentle rinse over the seals. If you've had a really wet ride, refill from a stream or a trail centre tap and go again.

The best portable bike wash is one you'll actually use: compact enough to live in the boot, pressurised enough to shift mud, and simple enough that nothing goes flat or breaks. The NewFlow 8 Litre Portable Shower weighs about 2 kg empty, has a carry strap and a 10 mode head that goes from a firm jet for tyres and frame to a soft spray for rinsing yourself down. The 3 metre coiled hose reaches round the whole bike with the tank standing on the ground. There are no batteries to charge and no pump to plug in. Add the NewFlow Shower Holder and it sticks to the car window or boot lid so you can wash with both hands free.

Rinse the bike, your shoes and your legs before anything goes in, then load the bike onto a bike mat or an old towel. A portable shower at the car makes this a two minute job rather than a wipe down with a damp cloth. The NewFlow Waterproof Beach Dry Bag and Changing Mat gives you a clean spot to stand while you rinse off and change, then the muddy kit goes into the bag so it never touches the seats. Riders who do this once rarely go back to driving home caked in mud.

Yes, and a low pressure portable shower is actually the recommended way to clean an ebike. Most ebike motors, batteries and displays are sealed against rain and splashes but not against pressure washing. Use a gentle or medium mode, keep the spray away from the charging port, battery contacts, display and cable connectors, and never spray directly into the motor housing. Remove the battery first if your manufacturer allows it, and dry any exposed contacts before you refit it. Rinse from above as if it were raining and you'll keep the electrics happy.

Yes, just don't put it in the tank. Spray your bike cleaner or degreaser straight onto the frame and drivetrain, give it a minute to work, agitate with a brush if you have one, then rinse with clean water from the shower. Keeping the tank water clean means the shower stays fresh for rinsing yourself, the dog or the kids. Keep degreaser off the brake rotors and pads, and rinse the tank with plain water after each session.

No. The NewFlow shower builds pressure with a hand pump, so there's nothing to charge and no cable to route from the car. Fill the tank, close the lid, pump 10 to 15 times and spray. If the pressure fades, pump a few more times to bring it back. That simplicity is what makes it reliable in a wet car park on a winter evening when a rechargeable pump would be sitting flat in the boot.

You'll get 3 to 6 minutes of continuous spray depending on the mode, and considerably longer in short bursts, which is how most bike washing happens. Pressure drops gradually as the tank empties, so give the handle a few extra pumps partway through to keep the jet strong. Eight litres is enough to rinse a muddy bike and still have water left over for your shoes and legs. On a really filthy ride you may want a refill, so keep a water carrier in the car if you're a long way from a tap.
