This video was filmed before Cruise left to go to the USA. He is starting his 40 hour journey back to Vietnam today and will be slower responding to comments because of this.

[@ChoaYeon]

Thank you for updating us about cruise!

[@keithandes2804]

Safe travels Cruise!!

[@swissride4k]

Thanks for sharing a nice piece of a cycle with us! I appreciate your efforts 😇

[@VicariousWalker]

thanks for sharing this bike review!

[@jjgpio484]

Very informative review. Thank you for sharing.

[@giancarlorivera8113]

Size 20 wheels are the best! Just did a 203km ride using my Dahon Boardwalk, equipped it with Schwalbe Marathon Plus tire, Brooks B. 17 leather saddle (champion special) and drop bar, you have a folding touring bike. Upgraded to a 9 speed cassette to have that 34T chain ring at the back paired with 52T front and your good on any uphill or long flat roads.

[@daviddjerassi]

I Love that bike in 20" form thank you for all your videos great information in each one keep safe i hope your sisters chemo is working well for her big hug.

[@TwoWheelCruise]

Thank you!

[@UserIDAlreadyInUse]

Another great video 👍. Keep it up guys... to add, love my Dahon Hit (Cheap and cheerfull starter foldable bike) that i got a few months ago. And Happy Thanksgiving to you two and your followers that celebrate it.

[@TwoWheelCruise]

Awesome! We really enjoyed the HIT when we tested it last year. It's a great starter folding bike.

[@virginianalangan6786]

I’m thinking getting a foldable bike myself. I live here in North Dakota USA. Thanks for the info. 😊

Thank you! It was a beautiful sunset this day.

[@jerryarnson2956]

I just bought the Mariner D8 International version in Osaka a few weeks ago and I'm lovin' it. I have an older Mariner that I use in Michigan during the summers so I am familiar with Dahon's quality. Keep up the great videos.

[@TwoWheelCruise]

Nice! I don't think I ever saw anyone riding a folding bike in Michigan when I lived there 10 years ago, hope more people have them now.

[@mercesletifer9553]

Where did you buy your d8 mariner? I'm also here in japan! Thanks

[@km2052]

Great review

[@DF-dd5nf]

Thanks a lot for the thorough information, I am also tall, so I am pleased that you have stated that it is suitable for tall people. I really enjoyed your video, it is very helpful. ❤❤❤

[@TwoWheelCruise]

Glad to help. Dahon is usually better than other folding bikes for taller people with their extra long seat posts.

[@georgehiphopforever]

I own Dahon Boardwalk nearly 18 years they are the best bikes,very reliable and can last for decades...not any problems even after all these years.

[@Toogoodtobetrue458]

I’ve been riding this bike for work commute now. I like it cuz I can take it in the passenger elevator in the office without the hassle of locking it up outside in NYC.

[@raysclim]

Great review as always ! Your positive review on marina D8 plays an important role for me to pull the trigger on this against brompton c line . ( I admit , I am not bromptonly rich ) 😊

[@TwoWheelCruise]

Half the price and more comfortable to ride 😉

[@raysclim]

Yes ! 16” & 20” wheel foldies review please !🎉

[@TwoWheelCruise]

Gotta make this happen

[@ph2869]

I am also curious about taking an old 20 inch folding bike and changing it to smaller wheels.. crazy or practical??

[@maryl.7226]

Yes, please do a video comparing 16” to 20” wheels. Thanks!

Love the pose beginning of video. Yes would love see comparison 16 versus 20 inch. Great camera btw.

[@TwoWheelCruise]

Thank you! We will try to film a comparison video too.

[@stevengoomba6490]

Nice review! I’m debating on whether to find a mini velo or a folding bike

[@zeniktorres4320]

Very nice bike alright. Also have a Dahon Mariner D8 (for 1.5 years) in black. It is the best I have every owned. It is a very comfortable stable quiet agile ride, as good if not better than my full size bike. It comes with mud guards, rack, strap, stand. Brakes and seat are good, and the Dahon gears are smooth and quiet. Well made and folds easily. I can put it in the car no problem and I just leave it folded inside my front door, ready to be used (it came with a Dahon bag which I place over it to keep it clean). I ordered a Dahon Landing Gear, which just bolts on, so I can wheel it around instead of carrying it. Thoroughly recommend this bike.

[@kelalamusic9258]

Great bike, Cruise. It's identical to my Dahon Vitesse i7. Only difference, other than color (mine is red), is the gearing. i7 means internal 7 speed hub. The quality of Dahon is superb. I think you both will truly like it. The only issue I had with mine, and that is I found the ride a little squirrelly. Hard to maintain a nice straight line. I mentioned that to you before, and you where right. Time and practice. As far as folding is concerned, I prefer to keep mine unfolded as well. I have no need to fold it up unless I want to pack it in the car. My wife has the Dahon D3. It's smaller than the Vitesse/Mariner. It has 16" wheels with fatter tires and a three speed internal hub. I enjoy riding that as well, and at 6'1" tall, it's not that bad. I hope you both switch over to the Mariner. You won't be disappointed. Enjoyed your video. Can't wait to see you both Merrily/Mariner roll along together in your next video. 👍

[@TwoWheelCruise]

The internal hub sounds really nice! And yeah, the handling on most folding bikes can be very twitchy at first, but you get used to them. We really like the change of pace being back on some 20 inch wheels

[@zeldajunkielol2]

Really cool bike! I've heard Dahon bikes are pretty good and the 20in wheels are very efficient, I think the ease of use in certain cases differ when it comes to wheel size so I'd think a 20in bike is better for long commutes and a 16in bike is better for taking on public transit and airplanes. I just recently bought myself a Brompton for my birthday and I love how small it is and it's perfect for me because I live close to the train station and it's a 40 minute walk vs a 10-15 minute bike ride and I can go straight to the airport from the train so it really opens up my travel options to live car free. Apparently Bromptons are never on sale but Amazon US has them heavily discounted right now. Hope you and your family are well Cruise. Btw I love your Snoopy shirt Thuong!

[@TwoWheelCruise]

That about sums it up. Wow, I didn't know Bromptons were sold on Amazon US, and with a discount to boot.

[@keithandes2804]

I'm thinking about getting an E bike!! I think it will be fun to ride!! Would love your thoughts!! Love the review of the Dahon Mariner. The taller wheels appear to be a more comfortable ride!! Great job as always!! Praying your family is well in the U.S. and my condolences to Thuong and her family!! Love your channel always puts a smile on my face!!

[@TwoWheelCruise]

Thank you! Ebikes can be a lot of fun

[@clee6746]

Dahon Mariner is a great bike and I almost bought one but in my shopping process, I ran into a small brand Solorock with similar quality and feature except it came with disc brakes and a curve upward back on the frame selling roughly at 60% of the price of the Mariner. The Solorock came with identical rear rack and elastic cord as well. I live in Canada, the other reason I did not get the Mariner is Dahon does not sell their bikes here, I'd have to order it from the U.S. and have it shipped over, that translates to extra cost(custom duty) plus the risk of being damaged on the way here.

[@714SNF]

thx for the video! do you recommend dahon or brompton?

[@HallOfFantasy]

Good opening shot.

[@TwoWheelCruise]

Thanks!

[@johnolsen394]

I use to have that bike that I used for work. On my way home , I don’t think I locked it right but the steering came unlocked and landed on my face. Never again. Locking it was always very difficult

[@betweenyouandme]

i like the 16 vs 20 inch comparison of foldies...

[@amigosmtb...alicanteespana727]

Buen video amigo 👌😃🇪🇦🇪🇦🇪🇦🇪🇦

[@briantyhy4880]

I have a montague 700mm folding bike and used it to tour. I developed problems with the rims and spokes braking. Not a recommendation for long distance touring with a load. I do like the folding ability for transport on planes.

[@grecinos2]

Love those foldable bikes! I’d like to get one so that I may put one in my car when I want to do a park and ride (explore). I’m interested in one with a belt drive drivetrain. The rationale being maintenance is easier than a conventional chain and cassette drivetrain. If you get a chance to test one out, you have my vote.

[@TwoWheelCruise]

They are great for fitting easily in your car! I haven't tried a belt drive folding bike yet, but I really want to.

[@bluefishblitz9577]

20-inch means less pedal and lower pulley scrapes, but my attention is currently focused on 1960's Schwinn Krates and Mantas. And yes, I'll even install grip streamers. Five speed Manta Ray with ram-horn bars for the win!!!

[@TwoWheelCruise]

Going full classic, nice!

[@simonsheena]

For easier rolling when its folded, pull out the saddle and use it as a handle so you don't have to bend down when rolling it.

[@TwoWheelCruise]

Thanks for the tip!

[@absolute_abundance]

Great video , please do a Brompton to do comparison with this Dahon

[@TwoWheelCruise]

Will try to do that

[@sktub569]

Rode a Dahon MU P8 for years. Dahon bikes are really good all around. I actually like it better than Brampton’s. The bigger wheel sizes are definitely a better ride and less twitchy.

[@TwoWheelCruise]

Yeah, the bigger wheels are much more comfortable.

[@evasossnitza]

Thanks for the video, very informative. I have a Dahon helios xl which is also 20", super comfy to ride on. But for a trip on an airplane I am still thinking of a 16" bike. Your royale is probably nearer to a brompton in design and material (steel?) but the Dahon curl is also made of alloy and therfore lighter. (I can't carry my 20" bike when folded.) If you ever get the chance for testing a curl that would be interesting. I can't find that many reviews of that bike here. Have a safe trip!

[@TwoWheelCruise]

Yeah, the 16" bikes are much better and simpler for international travel since they can fit down smaller.

[@chuongng]

Nice & detailed review. Which part of VN was the video was recorded?

[@TwoWheelCruise]

Da Nang

[@thecrazyToolfan]

5:05 enter vacation Cruise with the beard moustache and clothing, looks so relaxed. Chill 😎

[@TwoWheelCruise]

Da Nang is all about chill haha

[@Colombia20102018]

What’s the difference between the vitesse and this bike? Thanks

[@LaOwlett]

I'm short (5"2) and I'm concerned about the distance from the seat to handle. She has her arms out almost straight. I notice the stem has a tilt forward, I wonder if that could be reversed, and if so, how much that would mess with the folding...

[@rafriedman]

Really curious about which panniers work.

[@endtimeslips4660]

i also use Dahon Dove sometime. it crazy light bike. but it fixgear bike.

[@cesarmejia.8038]

Como es posible que las dos ruedas de la Dahon no queden alineadas para poder empujarla cuando esté doblada? Gran error.

[@paul.steckler]

I've had a Dahon Helios P8 since 2005, still ride it frequently.

[@TwoWheelCruise]

Awesome!

[@myfreakyvalentine]

That's a coincidence, I bought a Mariner 8 recently for travelling. I swapped out the bars for some wider ones and put on some better pedals, but apart from that it's pretty good. Mine does have markings on the seat tube though, strangely.

[@TwoWheelCruise]

Nice, enjoy! Maybe there are some regional changes.

[@myfreakyvalentine]

@@TwoWheelCruise Possibly? I am in Australia. Also they only came in silver where I bought mine.

[@zeniktorres4320]

@@myfreakyvalentine Also in Australia. Bought mine here, in black. But you're right the silver here was most commonly available for some reason.

[@donjohn2239]

Might buy a second hand restored Dahon classic California for work and train commute. Can someone tel me if they are good? Or should I go for a new decathlon foldable?

[@fredmcgough748]

How much do these kind of bikes cost? Is hard to find tires,etc. For them?

[@gregholbut7431]

Unfortunately, I bought a GLO version, cheapest bottom bracket had to replace it to stop creaking, two spokes broke after a few miles and the black paint? On the seat and handlebar rubs off.

[@Ancorarte]

Any other video testing the gears? Did you also test the Dahon Vybe D7 ( it's half the price of the Marine D8 )? Your model looks so sweet :)

[@zeniktorres4320]

The Dahon made gears are fine, smooth hassle-free changes. Had my Mariner D8 for 1.5 years. It made need adjusting now as there could be some cable stretch over that time (it has never been adjusted). Very happy with it.

[@JaredUnashamed]

Looks great! Safe travels back to Vietnam!!

[@TwoWheelCruise]

Thank you!

[@bengt_axle]

You're ready for a Charlie Brown Thanksgiving Thuong-san! Let's go.

[@BRecuyer]

Tern node d8 is better?

[@seemovielove3597]

I just check their warranty that Dahon requires user to have routine/yearly maintenance performed by Dahon's authorized dealer only. If you do not it will not honor the warranty. What do you think about this? Are you going to have routine maintenance by Dahon dealer? I would say it would cost $100 USD yearly for this maintenance service at dealer which I do want to perform the maintenance by myself. Thanks

[@12823matthewkao]

I like broadwalk more. much cleaner and classic look. you guys should check out Dahon D zero too. pretty nice retro bike.

[@TwoWheelCruise]

Yeah, the boardwalk is a beautiful bike

[@theaveragejoe5781]

The thumbnail is amazing. If you can get hold of an ebike, especially foldable, and can test it, I would be very interested.

[@TwoWheelCruise]

Thanks! Harder for us to work with Ebike brands here in VN since many do not ship here.

[@thecrazyToolfan]

Safest locks, securing folding bikes, are they easier to steal or keep safe? Can we get a small conversation about that?

[@meilong2338]

Wow, is that in Vietnam? It looks so modern and cool

[@TwoWheelCruise]

Yep, Da Nang

[@deborahclayton7105]

Didn't realize Dahon still had their brand of tires. Had to resort to some bargain-basement Schwabes to replace the dry-rotted tires mine came with. I live in the northeastern US, btw.

[@TwoWheelCruise]

I thought it came with Schwalbes but I guess some regions may still have them.

[@seemovielove3597]

It is on sale now during the week of Thanksgiving

[@TwoWheelCruise]

Perfect!

[@Ratlins9]

You really didn’t cover much as far as reviewing this bike. Maybe tell us how were the brakes, the shifting, any vibration, were the hand grips comfortable, did your feet slip off the pedals?

[@JamesWood-dj1lf]

I've been riding this bike for about a month kzbin.infoUgkxwC0IIeIomGQVeBWg-kKJaToZkLEFIA2W and a half now and I think it's fantastic. It helps me get to work on time every day since I'm able to fit it inside of public transportation rush hour. The price is great too, people are always shocked when they ask me how much I paid for the fold up and I tell them "200". It's easy to fold and installation when it ships is insanely easy. All you have to install when the bike arrives is one foot pedal, everything else is done for you. I do recommend you carry some sort of wrench to tighten any loose screws on the handle bar and seat whenever they get a little bit loose. Other than that I think it's a fantastic bike. Easily fits in the home, can fit inside a car trunk and can even fit in subway rush hour.

If only the third party brands would build a 20 inch brompton. There is actually! Mobot has a 18 inch carbon brompton. Too expensive and carbon folder would stress the frame.
