Frequently Asked Questions

How long does delivery take?

Free worldwide shipping on every order. UK orders usually arrive in 7–12 working days, international orders can take a bit longer. You’ll get a tracking link by email.

Will it fit my bike?

Yes. It hangs from a stretchy silicone loop that goes under the back of almost any saddle, or onto a bag or seat post.

How do I turn it on?

Squeeze the button once for a steady red glow. Double-press for flash mode.

Is it a proper bike light?

It’s a fun extra rear light that makes you more visible. Keep using your road-legal lights too — GlowSack is the cheeky bonus.

What if I don’t like it?

You’ve got 14 days to return it. If it arrives faulty we’ll replace or refund it, no need to send it back.

Tonight, not someday

Make every car behind you laugh.

One squeeze and your bike has the cheekiest light on the road. Perfect stocking filler for the cyclist who has everything.
