I arrived to Mostly E-Bikes about a quarter before they closed, needing a tube/tire on my semi-new Trek road bike. George dropped what he was doing and immediately gave me and the bike his full attention. However, he didn’t just patch it up and hand it back - he inquired about my uses for it, and thereafter informed me about its potential and its performance. The bike had the original super thin racing/road tires. If I was gonna move around on it, this wasn’t going to be practical, let alone comfortable. He then made some suggestions on how to make some basic changes and keep them inexpensive. The bike was patched. I rode it around for a few days, experimenting, and after a few visits to George’s shop and gaining inspiration by his own bikes, I decided to convert this Trek road bike into a commuter! He gave me many options and suggestions, educating me on tire types, their sizes, rims, calibration, break pads, drive-train, gears, seating, and pedal strokes, etc. I gotta say, althou...

My husband and I were in Oceanside preparing to head out for a pleasant bike ride when we discovered my tire was completely flat. Fortunately, we found "Mostly E-bikes" and George was incredibly helpful, changing my tube and tire in time for us to enjoy an afternoon ride. This was our anniversary weekend, so we were especially grateful for George's skill and willingness to help us out. We wish him all the best!

George is terrific. I bought a bike about a year ago, which I use to commute across the valley and back. Took it in to him after about two thousand miles for a tube-up, and got it back looking and feeling like a brand new bike, with updated software, new chain, and gleaming gears. Great bike at a reasonable price combined with excellent service. Highly recommend.
