Great shop, excellent products and large selection of bikes. George and his staff are both knowledgeable and very personable. From the time we walked in till we left, George made us feel like his number one customer. Spending time with us explaining the eBike world. We never felt pressured to buy. We have since purchased our first Electra bike and gear and plan to buy the second one when my color comes on.

I recently bought two Rad Mini e-bikes to celebrate the retirements of my wife and I. I asked the crew at Rad Bikes in Seattle, from whom I ordered the bikes, for a recommendation for a bike shop close to me. They recommended Mostly E-Bikes in Oceanside. On both occasions when I had each bike assembled at Mostly E-Bikes, I was incredibly impressed with the quality of the customer service I received. George is a great guy with a calm and friendly presence who had a genuine interest in my satisfaction of the services I received from his company. His communication was consistently prompt and informative. He had each bike ready within the time frame he indicated. He also helped me get a replacement rotor for my front brake. His staff is also great and has extensive experience! On the two occasions I was at his shop, George provided great service and was impressively friendly and personable. He definitely gets a 5-star rating and my endorsement! If you like great customer service - go see George at Mostly E-Bikes in Oceanside !!

In addition to performing a quality major maintenance job on my bike, George and his staff have generously given me tips on daily maintenance and riding safety. As a novice bike rider, I truly appreciate having this business and their services available. And it’s right there off the trail!

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, although he kept me within my budget, there’s no price on the attention and pride he has put into this bike. His service was superior, professional, and suggestions totally accurate! To this day, whenever I have questions, he responds timely even through email! This bike shop is the real deal and have recommended him to friends and family

I couldn't recommend more. I ended up with a bike that far exceeded the capabilities I was looking for at a price below what I was expecting to spend.
