We went to Mostly E-bikes to look for ones to purchase. George, the owner, was more than accommodating. He let my husband and I test several models, taking them out on the road as long as we needed. He suggested routes to take to really get a feel for each bike we tried. George is very informative about the different models of electric bikes he sells. He gave us the pros and cons of each one we took out for a ride. Once we decided on the Electra Vale Go for each of us, he assisted us in choosing accessories we wanted. When our bikes came in, George made sure that everything on the bike was adjusted to our liking and answered any and all questions we had. Since making our purchase, we have dropped in to see George a couple times. He is always more than happy to make fine adjustments, etc. I highly recommend Mostly E-bikes when looking to buy an electric bike. It will be a positive no pressure experience thanks to George.

Highly recommended. Knowledgeable and honest. Trust them to help match you up with the right bike. There's an adjacent bike path that's perfect for test rides. Their service team really knows their stuff, too. They just did a 2,000 mile maintenance on my Tern E-bike.

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...
