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.

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 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...
