With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

The Sirius, once the best of the best “to be seen” front light, now with the output increased to 950 lumens, can easily light the road ahead when required. The Sirius hits the sweet spot for power to weight, housed in a CNC machined aluminium body that features 240° front and side illumination, giving the flexibility to be used for the daily commute or longer rides.

Weighing in at just 90 grams, the Sirius 11 has been designed with weight efficiency in mind, without compromising on durability or quality.
