HOW IT WORKS

What happens when you join the 10k+ happy Huckleberry Customers

order your bike

When your order your bike on our site, it notifies us at the shop.
Day 1

We'll build it and put it in a box

After you place your order, we'll build your bike – so you don't have to. Derailleurs, brakes, and every bolt is adjusted properly. From there, it's time to ship.
Day 2

Your new bike arrives at your door

We ship new bikes 95% assembled. 
It takes 3 simple steps to get your bike rolling: 1. Mount the front wheel. 2. Attach the handlebars. 3. Put on the pedals
Day 4-9

Ride!

It's time to get rolling. You have a new bike to ride.
Day 9, 10, 11, 12, 13... every day.

Great Bag to complete the 1975 collection

This Bottle bag looks and feels great, style like Louis Vuitton designer bag which was inspired by Japanese Kamon Family crest design. Looks tasteful and luxurious, many complements and inquiries from people

Awesome all around

Fabulous company to work with. I sent in my fitting sheet sheet and they set it all up while taking the time to promptly answer all my random questions. Bike rides like a dream and I can finally hang with our club A group. Yay! And thank you!

Tubeless is where it’s at

New bike and new tires. Able to hang with the A group in our club now. 30 miles and just under 21 mph tonight. Used to get a lot of flats with tubes but never had one with tubeless

Fantastic Karate Monkey and Excellent Service!

I am super happy with the team at Huckleberry and my new Karate Monkey! They made buying and picking up the bike seamless and provided great advice and setup.

Outstanding customer service!

Incredible buying experience! When I felt I ordered the wrong size, Rocky did a bunch of research reading reviews and looking at manufacturer recommendations. He explained the tech and various options. In the end, he ordered another size for me and was fully accommodating. After receiving the bike, it came with a mud guard damaged in shipping. They sent me a new one within days. I talked to Jonas and informed him the bike needed a little derailleur tuning and adjustments. Took it to my local bike shop and Jonas reimbursed me so I would be 100% satisfied. And I am! I'm blown away by how helpful they were, super knowledgable and addressed all my concerns without question. Hands down my best online buying experience! Huckleberry will easily get my future business! Thank you guys!

Rocky was Outstanding!

Rocky was incredibly helpful, reassuring and made me feel confident about the bike. He was informative, thorough and didn’t rush through the purchasing process. Thank you for your upstanding service and the joy you brought my family.

Perfect for my daughter!

Great bike. Great bike shop

We got the Compact Neo a few weeks ago and have really enjoyed it. It’s lighter than other e-bikes but manages SF hills and terrain well and has good battery range.
The folks at the shop have been super helpful in getting us set up and adjusting the seat post for one of my kids. I’m glad I found this local bike shop!

Great Support/ Fast Delivery

It's hard buying a bike when you can't throw a leg over it. Huckleberry answered all my questions until I was confident in my purchase and within a couple of days it was at my door. Tuned perfectly and ready to ride once I installed the front wheel and handlebars. Very pleased.

Huckleberry Bikes

I love my Kona Rove LTD! I purchased my bike in person but had it shipped to my home out of state. Everyone in the store was super helpful and my entire experience was positive and easy. My bike arrived packed with care and expert packing. It was easy to complete the couple of finishing tasks (handlebar and front wheel) to be ride ready. Highly recommend Huckleberry bikes!

Great service, great bike!!

Buy your next bike here!

Purchasing my bike from Huckleberry Bikes was the easiest, most pleasant experience for me. Literally, I purchased my bike on Christmas Day. Unlike other places online, they actually had it in stock, as indicated on the website. The bike came promptly, arriving on the exact day they indicated, even though I live nearly 3000 miles away from the shop. When I received the bike, they spent time on the phone with me to help me get it ready to ride. I will be buying my next bike from here, for sure!

Perfect Christmas Gifts!

I ordered accessories for my daughter and her husband, who had ordered gravel bikes from Huckleberry. Jonas helped me with my purchase and made sure the items arrived before Christmas.

Great Delivery

Bike was nicely set up and packing was great.

Salsa Fargo

Bike was packaged well and you handled my upgrade requests smoothly. Deraiiller is out of adjustment and won’t shift into the easiest gear. That is frustrating as it may require $ to be spent at local bike shop.

Great customer service!

I’m so glad I ordered my new Kona Libre EL from huckleberry’s web site. Jonas the owner was very helpful and answered all my questions via email. The bike was packed very well in the box and was relatively easy to assemble except the dropper post that Jeff did a great job explaining me what to do over the phone. The next day after assembling the bike rode it for 35 miles at our annual local bike ride event. It was so much fun and the bike performed very well. I love my new bike and wanted to thank you again guys for all your help.

Awesome Service and Awesome bike!

The folks at Huckleberry were extremely helpful and communicative during the purchase process. They let us know that they would be getting the bike in stock and reached out again when it arrived. Great step up bike for my kid. It's doing great on trails and in the hood
