Brother Cycles Kepler│House Build

Finance options available with:

Built for city cruising, big pushes, and even bigger skids, this custom Brother Kepler in 'Teal Is Real' is a flat bar rig with timeless charm and a modern twist. This one's for the in-betweeners - riders who clock commuter miles during the week, then point their wheels toward weekend excursions.

✅ What we like about it

Well, aside from the obvious - the colourway 😍 - we love how niche you can take this build. It all starts from the frameset. A lugged steel fork with dynamo routing means you can set it up to run lights that never need charging. Add sleek internal cable routing, a beautifully classic brazed seat collar, and Brother’s signature oak leaf head badge, and you’ve got a bike built for the connoisseur.

We leaned into the everyday urban side of the Kepler here - ditching drops for flat bars to keep things casual, but playful enough for a jib or two on the ride home. With a chrome Ritchey finishing kit to tie it all together in timeless fashion. A tough-as-nails GRX groupset takes care of the shifting. And rounding it out? Velo Orange hubs and pedals for that final flourish.
