  • 6 lighting modes for every ride. Day, night and rain.

  • 100% battery display, always. No guessing if you'll make it home.

How does the brake sensing actually work?

The taillight uses a high-precision accelerometer sensor that detects the moment your speed decreases. When braking is detected, the light automatically increases in brightness to alert drivers behind you, no wiring, no brake lever attachments needed. It works completely autonomously.

Will it fit my bike's seat post?

Yes. The West Biking taillight features a universal saddle rail mount that fits virtually all road bikes, mountain bikes, and commuter bikes. Installation is tool-free and takes under a minute.

How long does the battery last on a full charge?

Battery life varies depending on your lighting mode, but you can expect anywhere from 5 to 20+ hours of use. The built-in LED display shows your exact battery percentage in real time, so you'll always know before heading out. Recharges fully via USB in around 1-2 hours.

What happens if it gets caught in the rain?

The taillight is built with weatherproof construction, making it resilient against rain, splashes, and wet road conditions, perfect for UK riding where the weather rarely cooperates.

30-Day Money-Back Guarantee

Not satisfied? We'll make it right. If for any reason you're not happy with your taillight within 30 days of purchase, contact us for a full refund, no questions asked. We're confident once you ride with it, you won't want to ride without it.

I was sceptical, felt too light to be real. Then I did a 90km race and didn't pump up once beforehand. Rolled the whole thing on the same pressure from the week before. Converted for life.

Reacts in milliseconds

Brighter when it matters most

Real-Time Display

A tiny LED screen on the body shows your exact battery percentage at all times. Short press the button even when the light is off to check your charge before heading out to avoid any mishaps, no more unexpected dead lights mid-ride.

Always know your charge

Never caught in the dark

Hear From Daniel James, Cycling Coach

Founder of Road Cycling Dvelopment Programme

Title

I recommend this to every cyclist I coach, from beginners to seasoned commuters. Most riders don't realise how little time a driver has to react at 30mph, a standard blinker just isn't enough. The moment I saw the brake sensing technology automatically flare on deceleration, I knew this was different. I've had two near-misses in my cycling career that a light like this could have prevented. It's not a gadget, it's genuine protection.

Stop Riding With a Light That
Let You Down

Basic taillights were never designed with your safety in mind. They blink and that's it. No awareness of when you're stopping, no intelligence, no real warning for drivers. Cyclists have quietly accepted this for years. This changes that. Same size, dramatically better protection.
