The Bunch is a really enjoyable and practical way of transporting multiple kiddos. Before this bike, and while we only had a single child, I would ride my solo e-bike while baby-wearing our daughter. However, at 3-years-old, she was starting to get a little heavy and too tall to continue this for much longer; and once we had two kids and our youngest could be apart from his mother long enough, I needed to up my game. I wanted to keep having the kids in front where I can see them and interact with them rather than put them in a bike trailer, so I searched around and found Bunch as the perfect solution. The Bunch has been great for that -- a ton of fun for me to ride, and with both the 3-year-old and the 10-month-old (in a toddler seat) enjoying it as well. We've taken in on several rides already, both during daytime and night-time -- and both rain and shine -- and it's been a blast in each of those conditions!
The bike handles pretty well on a gravel road, and up a pretty steep (~18% grade) gravel hill -- though of course it feels smoother to ride once we get to pavement or a well-packed gravel road.
The bike isn't perfect, but I think it's the best that exists on the market today. There are a few improvements I would love to see Bunch make, and I've given feedback on some of those items already. Most notably, the thumb throttle being impacted by the passive-assist setting is a poor design choice (i.e., you can't be on level 0 and still use the throttle, you need to bump up the PAS level first; however, I hear that it's on their radar to improve eventually, decoupling the throttle from the pedal-assist level). The motor isn't silent, which is a bummer (by contrast, it's silent on my solo e-bike from Rad Power Bikes), but it's also not too loud -- and on the flat I just put the bike into assist level 0 and get some excercise, whereas once I need the extra help I don't care how loudly the motor whines. Other small things: the headlights could be brighter (but it's easy to just attach a standalone bike light); and the toddler seat faces forward rather than backwards by default and doesn't have shock-absorption (but I did a DIY modification to have it face towards me, and sit atop the cushion for some shock-absorption on the bumpy gravel road).
Overall it's a great family bike, by a company that's got fantastic customer service and a really positive and helpful Facebook group (search for "Bunch Bikes Club: Owners & Friends"). I'm glad I got the bike, have already recommended it to friends, and look forward to riding it with the family for many years to come!
