Life's better with a Bunch Bike and a Labrador

We are having the most fun you can have riding a Bunch Bike with my best friend Shelby (my service dog.) She goes everywhere with me now because of the Bunch Bike. We're either in the truck or riding around on the Bunch Bike. We've been downtown on Main Street, at the mall (Security allows me to ride the bike inside the mall) and at our local park enjoying time together. I've been asked a lot of questions about the bike. Did I make it? Where can I get one of those? Its been a showstopper for sure when we're inside the mall. And of course, Shelby enjoys all the attention when we stop and answer questions. Looking to ad a few accessories in the coming days and we're having a absolute blast.

This sounds amazing, I'm so glad you and Shelby are having fun together! Makes me very happy to hear that you're able to get around and have new adventures with your service dog. Thank you for taking the time to share your feedback - bet you turn some heads at the mall!

The pups are loving this bike! We are still all getting trained on this (myself included), and the dogs are taking to it quickly! Stay tuned for more great pics! @onthetrailnorthshore.

Hi Rachael, so glad to hear the pups are loving your Bunch Bike! Looks like a great way to get the word out about On The Trail too. Thank you for taking the time to share. Wish my dogs could come hang out with you!

We love everything about this bike

We have had our bunch bike for 3 months and we can't imagine trail work without it. We use the bike at least once a week to haul tools to our volunteer events. However, one thing we didn't anticipate is how much our adult volunteers love hopping in the bike and riding down the trail to do different tasks. This bike isn't just for transporting kids! Adults love it too.

If you are on the fence for buying a Bunch Bike take advantage of test riding one. Ask questions! Talk to other users. Figure out if it is a good fit. Another awesome thing about Bunch is after you purchase a bike you aren't left hanging if you have any issues or questions. The customer service with Bunch is truly amazing. Buying a bike you are part of the Bunch Bike community. If Bunch Bike can't answer your question, another user is there to help.

Excellent customer service, great biking experience

I test rode a Bunch Bike four years before I purchased one and my only regret is not buying one sooner. The bike itself is great. What impresses me most about Bunch is their customer service.

I do the big grocery shop, tree hauls from garden store and recycling runs with ease – faster than I did with a truck.

The bike takes some practice to ride to become proficient at handling cambered roads and turns. I also found that my 33kg dog requires more than one anchor point to keep her secure the cargo box. I live in a dense, urban area and I am satisfied with the ability to lock up the bike even on crowded bike racks. I would recommend, the rear wheel lock and alarm system to any potential buyer concerned about security.

I love the extra battery I bought. I can get to my regional park with gardening gear (70kg) across 24km on two batteries.

Hi Kimberly, we're so glad you and your pup are enjoying your Bunch life! You're not the first to tell us you wish you'd taken the plunge sooner - you know what they say, the second best time is today. Thank you for taking time to share your advice about security for your dog, and for your bike. We love that our owner community is always here to support each other and share tips!

Finally invested in a cargo bike this summer after talking about it for 5+ years. After riding 2 wheel options in Europe, I was nervous about getting a trike, but I’m so happy I went with a Bunch. I bought it to transport our dogs, but have found myself using it for everything. After about a month, I’ve replaced all my around town car trips with this bike. The Bunch team was great to work with and added many cute additions after I mentioned our dogs in the order notes. It arrived fully built and charger and hit the road 5 mins after unboxing. So far, on our local roads, it’s been handling fine at ~15mph. My gf rides in the box and has mentioned it’s a bit bumpy, but part of that could be our roads. The dogs like to chase bikes more than ride in them, but we’re training them to enjoy sitting in it and it’s improving. It is such a mood boost to run errands on, listening to reggae and getting plenty of smiles/comments from neighbors, other pedestrians, and even people in cars. If you’re teetering on whether to invest in one or not, I recommend doing it.

Hey Alex, I'm so glad you're loving your bike life! Definitely the most fun way to tool around town with your pups and your best girl. Like you say, it's a mood boost - which is more than I can say for running errands by car!

Bike is great for us and service even better

We purchased this bike after a brain injury limited my wife’s ability to ride on her own. Bunch talked me thru options, providing excellent pre- and post-sale service. I appreciate the focus on inclusion for people with special needs.

We have been enjoying it for about six weeks and are very happy. She and I can easily ride with our 60 pound pooch. And, it’s a hit with the grandkids.

Glad we found the “bucket bike” and their team.

Wow Jeff, that is great to hear - I'm so glad you are back to enjoying the bike life together. That's what our inclusion program is all about! Hope you have many happy rides together over the holiday season.

Lelac is the best!

Lelac went out of her way to make our shipping of my bunch bike perfect and smooth and quick. The shippers took horrible care of the bike and she made everything perfect for us and replied to all emails promptly and really cared that I got my trike. I have stage 4 cancer so stress is the opposite of what I need in my life and she made everything stressless. She was very help. I love my bunch. Only wish I would have gotten the mesh to put my drink in it and snacks. Since I have to drink water constantly I wish I would have ordered the mesh holder. I recommend for myself the mesh than the cup holder so my son and I can keep or goodies in it. I’ll have to order when I feel better. Thank you Lelac and Bunch!!

Hey David, thank you for sharing this - it's an honor to be able to support your family and help you get out and about with your son. I know you probably have your hands full handling the medical - I'm glad our team could help make your bike life stress free!

The best dog cargo bike!

With our new K-9 Bunch Bike we are able to transport our two golden retrievers all over our bike friendly city. Everyone loves to see the dogs in their new ride, it brings a smile to everyone who sees them. Our 7 year old grandson loves the rides too. The best purchase of 2023 for us. Thanks bunch bike!
