The color options for both bikes are pretty cool! I’m leaning towards the white Brompton, but the brushed finish of the Dahon is sleek too. Decisions, decisions…😅 Anyone have pics of their rides?
Colors definitely add a personal touch! Share those pics, everyone!
I’ve got a black Dahon, and I love it! I’ll post a pic! 📸
I think the Dahon Mariner is such a good value! I’ve had mine for over a year, and it’s still going strong. I’m not a pro cyclist, but it handles my daily commute like a champ!
Glad to hear you’re enjoying your Dahon, Rachel! It’s definitely a solid option for daily commuting.
That’s awesome, Rachel! How does it compare on hills? I’m curious since I live in a somewhat hilly area.
Brompton’s marketing is on point! But does anyone else feel like they’re charging a premium just for the name? I mean, it’s a bike, not a fancy watch! 😅
That’s a common sentiment, Tommy! Brand value often affects pricing. Both bikes have their dedicated fans!
Right?! I love my Dahon and it didn’t break the bank. Seems like you pay extra for the Brompton’s reputation.
I’m kind of skeptical about foldable bikes in general. Are they really as sturdy as regular bikes? I’ve heard mixed reviews.
I get your skepticism! I was worried too, but I’ve found my Dahon to be really solid. Just make sure everything’s tightened up before you ride!
Great advice, Julia! Proper maintenance can make a huge difference.
I have a Dahon Mariner and I love it, but I did notice it can be a bit bulky when folded. It’s not terrible, but definitely takes up space. Anyone else experience this? 🤔
Totally! I have to rearrange my trunk every time I take it out. 😂 But once it’s set up, I enjoy the ride!
