These are my current bikes:
1991 GT Timberline mountain bike
1994 Diamondback Apex mountain bike
1994 GT Tequesta mountain bike
My first foray into vintage bike repair
2014 (Gen 2) Tern Link D8 folding bike
I bought this used and it was my commuter bike for many years. Starting to use it again for a commute segment. I just redid all the brake and shifter cables, relubed the derailleur, and replaced the chain. I also added the v2 front luggage rack and a Kanga rack.
2022 Specialized Sirrus X 4.0 flat bar gravel/fitness hybrid
This bike got me back into cycling after a few years off, it's great for anything from rough country roads to gravel and I even rode it in a cyclocross race!
2021-2023 Soma Double Cross drop bar CX/gravel bike
I cannibalized the Royce Union RGF into this beast. It's geared like a mountain goat with 46/30t in front and an 11-36 9-speed cassette in the back, I wanted a bike that would handle everything LA has to offer.
2024 GT Sensor Sport full suspension mountain bike
My first real mountain bike. A completely different riding experience from the rest of my bikes.
