Let customers speak for us
Matthew and Drew were great to work with helping me find the perfect eBike!
Great bike and even better service ! Mathew’s energy and passion for cycling is off the charts ! I purchased two bikes from this company and couldn’t be happier
Top shelf all the way. Very knowledgeable and informative. Prompt quick service at a reasonable price . All around a worthwhile experience.
Matt’s a great guy! Knows his products and customer. Recommend buying your bikes here!
I recently purchased a Velotric Summit 1 e-bike from Garage Cycles, and the experience was top-notch. While the bike is available for the same price online, choosing to buy locally was absolutely the right move.
The shop is beautifully maintained, clean, well-stocked, and incredibly easy to access. The proprietor, Matthew, was fantastic to work with. He had multiple sizes in stock, took the time to fit me to the correct frame, and clearly explained all the bike's features and technology before I took it for a spin.
The real testament to their customer service came on Memorial Day. I ran into a minor technical issue, and even though the shop was closed for the holiday, Matthew met me at the shop to quickly resolve it and get me back on the road. You simply don't get that level of dedication with an online purchase. I highly recommend Garage Cycles!
Love my Discovery 3 ebike. Matthew was very helpful and answered all my questions and let me ride the bike I was lookingto buy. Great guy and great bike shop.
Matthew was great love the start up energy great bang for th buck
GC Annual Membership - we'll see you in the garage™
I picked up a Green Bright STW with Shimano 105 from Garage Cycles, and I’m really impressed. The bike is surprisingly comfortable and extremely aero. I always get a bunch of compliments on group rides.
Matthew is awesome to work with. He's been nothing but super helpful, friendly, and really knows his stuff (he rode in the Tour of Utah). Definitely recommend Garage Cycles if you’re looking for a great bike and great service.
Awesome Value! Easily worth the membership, and this organization is awesome to work with. Great folks, great values, and great service!
I recently joined the GC Annual Membership and I couldn’t be happier with the experience! From the moment I signed up, everything felt smooth and professional. The membership has already added so much value – exclusive perks, great community vibes, and that special ‘garage family’ feeling that makes Garage Cycles stand out from other cycling groups.
It’s not just about cycling; it’s about being part of a passionate community that motivates you to push further while still keeping things fun and friendly. Looking forward to an exciting year ahead with GC – see you in the garage™!
Price was outstanding. The e-bike came in excellent condition couldn’t be happier. Thank you.
