Bike Safety

Contrary to popular belief, tamper-proof locks do not exist.
Bike locks are intended to act as a deterrent, making it more complicated to steal a bike.

A good lock has an anti-pick locking mechanism and is made from materials that can only be cut or broken with special tools, which makes theft more difficult.

Safety

The security rating helps you choose the lock that’s best for your use. Btwin and third-party laboratory CNPP created a test protocol based on real-life theft techniques.
This unique protocol assigns each lock a rating from 0 to 10 that indicates how theft-resistant it is.

Poncho designed for bike commuting, with a loose fit so you can wear it over your normal jacket and a 20 L backpack. 
The unisex cut covers you from head to thigh.

Adjustable hood that moves with you.
Store easily in the pouch: W 26.5 x H 22.5 x D 5.5 cm (10 1/2 x 9 x 2").

Urban mobility design

Even though this poncho protects your upper body really well, it’s vital to pair it with overpants to protect your legs from the rain. The poncho doesn’t protect your shoes, so in heavy downpours, this could leave you with wet feet. The poncho is easy to put on and store your bag. Put it on in seconds!

How to stay dry

This poncho’s durable, coated fabric and sealed seams make it entirely waterproof. We measure the fabric's water-resistance to the pressure exerted by a water column, expressed in mm (test based on ISO 811 standard). The product is resistant to pressure from 2,000 mm of water after 5 washes. The finished product is approved in a shower test in the lab, where we recreate the conditions of an average downpour: 60 L water per square m per hour for 2 hours.

Waterproofing

This poncho is certified for night visibility (EN17353 standard), with reflective strips to make cyclists visible even at night.
The reflective elements have been carefully positioned to account for the constraints of cycling so that they guarantee 360° visibility at 50 m at night when car headlights are shining on them.

Certified visibility

Hydrophilic coating (RET = < 12): Limits condensation inside the garment. To determine a fabric’s breathability, we test its evaporative resistance or RET (based on the ISO 11092 Standard). The lower its resistance, the more the fabric allows perspiration to escape, increasing its breathability. For example: RET < 9 = extremely breathable fabric. 9 < RET < 12 = highly breathable fabric. 12 < RET < 20 = breathable fabric. RET > 20 = slightly or not breathable fabric.

Waterproof and breathable

Developed by our apparel team, this poncho allows you to enjoy your urban rides even in the rain!

How to choose your helmet size

European standard sets the requirements and test methods for helmets to be worn by users of rollerblades, skateboards, scooters, and bicycles. The corresponding requirements and test methods cover the following aspects: construction, including field of vision; shock absorption properties; characteristics of the retention system, including the chinstrap and tightening devices; and marking and information.

EN 1078 Certified

We recommend replacing your helmet in these two cases:

1. After a fall:
In the event of a fall, the material of your helmet can deteriorate or even break. Sometimes, you won’t even notice. That’s why we recommend replacing it if you have the slightest doubt.

2. After five years of use:
The foam deteriorates. It can deteriorate due to impact, storage location, the climate, and its use. We therefore recommend replacing your helmet at least every five years.

When should I replace my helmet?

Three easy steps for adjusting your helmet in two minutes:
1. If necessary, pull your ponytail through the back of the helmet (lower the dial’s rim).

2. Clip the straps together with the buckle and adjust: make sure you can slide two fingers between the strap and your chin.

3. Adjust the tightness around your head using the rear dial.

The helmet should be in contact with your head without tipping forward, backward, or sideways, even when you’re moving.

How do you adjust the helmet?

Based at the Btwin Village in Lille, our product design team constantly works to make Biking more comfortable for our users.
Our goal is to create products that respond to our users’ needs and promote a good Biking experience.

All of our "FastFlow" bottles use the SureSnap® valve, the best on the market. This valve controls the flow of water effectively and precisely. When you press down, water squirts out of the mouthpiece.
Plus, the anti-leak mouthpiece can stay open while riding without water dripping onto your bike's frame.

SureSnap® valve

The mouthpiece is 100% watertight in closed position. Use this position for mixing the isotonic drink in the bottle or for carrying it in a bag.
Once on your bike, leave it open. The SureSnap® valve prevent leaks. Drink quickly and safely!

How to use the FastFlow valve

There’s nothing worse than a plasticky taste or smell in a water bottle. But this is the case for most cycling water bottles. 
We tested numerous plastics before finding just the right one, which is supple and has a neutral taste and smell. When blind tested against bottles from other leading brands, ours were the most neutral-tasting.

No more plasticky smell or taste.

Clean the water bottle thoroughly after each use. If you use isotonic drinks, rinse all parts of the bottle, cap, and mouthpiece to make sure there is no liquid remaining inside. Use liquid detergent and a long brush to clean the bottom of the bottle. 
Dry well and store with the cap off. Otherwise, mould could develop in the bottle.
Do not put in the dishwasher (particularly above 70°C).
