Fit first, electric second.

Luma is a lightweight all-road bike built around the ride, with discreet assistance that feels natural when you need it and disappears when you don’t.

A special milestone in Alex Albon’s Williams career provided the inspiration for a custom FiftyOne Sika.

Here’s a first glimpse of Alex’s Sika, drawing inspiration from his helmet design. The Sika will sit alongside his FW14-inspired Assassin pit bike.

The full video lands tomorrow.

A raw carbon Sika, Campagnolo Super Record and SES 3.4s, built up by Peter with the attention to detail that makes the difference.

Built for Alex Albon. Inspired by the FW14.

A one-off FiftyOne for a record-breaking Williams weekend, as becomes the team’s record holder for Grand Prix starts.

The bike takes its cues from the same place as his special helmet: Nigel Mansell’s 1992 championship winning Williams.

A small nod to a big piece of Formula 1 history.

Still earning its keep.

An 80s drill press, a diamond hole saw, and a proven process that’s changed very little over the years.

Cycling Weekly reviews the Sika. The bike had to do the talking. This time, it did.

Delighted to support local club Gravel Extravaganza 2026 right here on our doorstep.

Irish gravel is still in its infancy, but all the ingredients are there. The trails, the scenery and the community. Events like this are what push it forward.

We’ll have the FiftyOne Assassin involved on the day, with a limited number of demo bikes available to ride.

We’ve also limited numbers left of our current Assassin offer at €2999, fully available through the Bike to Work scheme. A bike built exactly for this type of riding.

See you in June!
