FAQ

Common questions

Everything you need to know about the HelixLok

Is HelixLok difficult to mount to my bike?

Not at all! The bracket is designed for universal fitment. You can use the standard water bottle boss screws on your frame or the provided heavy-duty straps to mount it anywhere. Setup takes less than 3 minutes.

How long is the lock when fully expanded?

The HelixLok expands to 85cm in total circumference. This is plenty of length to secure your bike's frame and one wheel to a standard street sign, bike rack, or fence post.

Will it scratch my bike's paint?

No. Each hardened steel link is encased in a thick, waterproof ABS coating. This soft-touch material protects your frame from scratches and dings while providing a weather-resistant barrier against rust.

Can I reset the combination code?

Yes! You can reset your 4-digit combination as often as you like. Instructions are included in the box to set your personal code in under 30 seconds.

Is it heavy to carry?

The lock weighs approximately 800g. While it's made of solid steel, the folding design distributes the weight more efficiently than a U-lock, and the frame mount ensures you don't feel the weight while riding.

What if I'm not happy with the security?

We offer a 60-day money-back guarantee. If you don't feel it's the most secure and convenient lock you've used, just send it back for a full refund. No questions asked.

Is it suitable for motorcycles or E-bikes?

Yes! The heavy-duty 5mm steel links are perfect for high-value E-bikes and can be used to secure motorcycle wheels or helmets. It's built to withstand harsh environmental conditions from -30°C to 60°C.
