The Genesis Day One in Forest Green is what Genesis calls their "triple threat"—a bike that sits exactly at the intersection of a super-commuter, a touring rig, and a gravel explorer. It borrows the heart of the CDA range by using a double-butted ALX8 6061 aluminium frame, but adds a heavy dose of utilitarian dependability with an internal gear hub. The Forest Green gloss finish is classic and understated, designed to look as good arriving at a city office as it does leaned against a fence on a muddy country lane.
The standout feature of this build is the Shimano Nexus 8-speed internal gear hub. By moving the gears inside the rear hub, Genesis has created a bike that is virtually immune to the grit and grime of winter commuting. Unlike a traditional derailleur system, the chain stays in one place, significantly reducing wear and maintenance. Controlled by a Microshift bar-end shifter, it offers a clean "singlespeed" aesthetic while providing enough range to tackle significant hills even when the bike is loaded with panniers.

Key Technologies
Shimano Nexus 8 Hub: Offers a 307% total gear range. Because the gears are sealed, they are protected from rain and road salt, making this one of the most reliable drivetrains for year-round UK riding.
CDA-Inspired Alloy Frame: The use of aluminum makes the bike lighter and more reactive than a full steel build, which is a major benefit when darting through city traffic or accelerating away from lights.
Bar-End Shifting: A nod to classic touring bikes, the bar-end shifter is mechanically simple and less prone to damage than integrated "brifter" style levers, especially if the bike is tipped over.
Unrivaled Mounting Points: With mounts for front/rear racks, full-length mudguards, and triple-boss fork mounts, this bike can be configured as a minimalist city flyer or a heavy-duty trans-continental tourer.
