Restoring a Tempest Blue Brompton back to life
A few months ago I picked up a blue Brompton as a new restoration project and a way to learn something different. I specifically wanted a Brompton because the whole folding system makes it completely unlike working on a regular bike — more complicated in some ways, but also way more interesting. I figured it would force me to learn new things, and it definitely did.
At first glance the bike actually looked pretty decent, but after a quick wash I decided to completely strip it down anyway so I could inspect every single component properly and restore anything that needed attention.
In the end I replaced the tires, cables, saddle, grips, mudguards, and one of the shifters that was completely trashed. I also polished the entire frame to bring the paint back to life. The transformation was honestly bigger than I expected — the bike barely shows its age now, and the blue really shines again.
What I enjoyed most about this project was discovering how cleverly engineered these bikes are once you fully take them apart. Every little mechanism feels intentional, and restoring one gave me a whole new appreciation for why people love Bromptons so much.
I documented the whole process along the way, from the first cleaning to the final rebuild, and I thought some of you might enjoy seeing it.
For those of you who’ve worked on Bromptons before: what part surprised you the most when you first tore one down? And for the longtime owners — what’s the one upgrade or detail you think makes the biggest difference on these bikes? 🚲✨
