    Yeah, I was surprised by the price...thought it would be higher

    With something in tow...the perfect beachcombing rig?

    The specs on the $6885 one doesnt say anything about it being fat.

    At the top of that column, it says "Mountain/Sand & Snow". I took "Sand & Snow" to mean the fat version.

    I mostly quit riding my Kawasaki because the riding areas are overrun with Quad-tards. Does this mean they will be ruining the MTB trails too?

    You will never see one of these on a MTB trail. I'm still waiting to run into someone on a fat bike and fatbikes are infinitely more plentiful than these quads.

    wow. with those closeups, the sub $7k price seems very reasonable.

    edit: looking closer, I don't see how they can make any profit at that price.

    what IGH is in that relay shaft/transmission setup?

    the rear diff looks too small to be anything but a spool.

    It could probably float over soft sand where my 4.8" tires would be getting bogged down.

    I had a Rhodes Car 4 wheeled passenger bike. That thing wasn't a fat bike by any means but it literally sucked the life out of every pedal stroke. The turning radius was also horrible! I couldn't sell that beast quick enough once I realized that unless you live on a pancake flat paved island, that thing was NO FUN WHATSOEVER(and seriously, nobody loves things that pedal more than me!)

    It may offer more float, but its also as much fun as riding a bike with training wheels...

    mmm hmmm, and having all 4 wheels driven rather than just the rear wheel of a bike is a sizeable advantage as well.

    Kinda looked like the barefoot toddler at the end of the video was moving at least as fast as the quad and the guy riding was spinning those cranks at a non-leisurely cadence.

    Seems like a fast walk would be quicker, simpler, easier and $7k less.

    But utterly cool at the same time. Years ago my grandfather told me about the first time he saw a car. He was born in 1891. He thought why would anyone want one of those? Sound familiar?

    All four wheels are not driven. It is rear wheel drive only.

    It's a brilliant piece of work.

    I'm sure there will be people who are otherwise unable to ride fatbikes who will be able to use this to enjoy some of the cycling pleasures we have. I'm looking forward to seeing them on the trails.

    I hope the builders do well with it.

    Oh you mean for people with poor balance and thus cant ride a 2 wheeled bike... They already make something for that.

    I don't think we need to worry about pedal-quads taking over the trails. At $7K and 70lbs there will never be many of them.
    There has already been the Lightfoot Cycles quad:

    And the Utah Trikes quad:
    Fat bike quad!-main.jpg

    I think the two telling points in the video are 1) the gear he's pedaling (low, with high cadence) and 2) the fact that he stops pedalling at one point and stops immediately. Ok, so this is on dry beach sand and those are 4" tires. He should have twice the float, but he's also got twice the rolling resistance.

    Technically speaking, this is a masterpiece! At least in the suspension/steering parts. It looks like the front and rear share parts, so it wouldn't be too hard to make it a 4x4 - just need 2 more differentials! I think the frame is overbuilt - looks like they tried to make it still look like a bicycle while adding things to it.
    This isn't a "you're doing it wrong" topic.

    Really? I have to admit thet I didn't look that closely. I bet I was looking at the rear. Well, that is a shame.

    I'm building one of these myself. I used 4 Lefty forks and a Walgoose. I put a hitch rack on the back and I'll use it to haul my fatbike to the trailhead. It will also have stickers on it.

    Impressive engineering, though it's not my particular flavor of "crazy". Now balance impaired people have a radical solution, if not completely practical. Who knows? Maybe someone has a damn good use case.

    A replacement for a bike?

    No.

    But IMO a very well engineered quad. A perfect grocery getter / beachcombing rig, a different sort of play thing for kids and adults alike. As others have pointed out, a smooth ride for the balance impaired...make that an E-Quad.

    Honestly, I think they are on to something here, just need to apply the right marketing approach. True, the price is high, but IMO a good value for the $. Lets not forget that 78# machine was with Bud & Lou on clownshoes...I think, and Surly tubes, I suppose...
    room for improvement!

    An off topic note...yesterday I saw a homeless type on a bicycle towing 3 trailers; could not believe it...going at a fair clip too. The stop sign was too far back for me to watch for that aspect...(????)

    If I were a double amputee then I would want to convert one of these to a hand-pedal system. It would take a lot of work and I wouldn't get far but I could at least get myself to the waterline. It would sure beat sitting at home on the couch.

    I don't think rolling resistance would be much more than a normal fatbike. Rolling resistance does not double with twice as many wheels, unless the total weight of the rider and vehicle is double.

    look at the recumbent trikes that are so popular. they are very fast. rolling resistance on a quad will be slightly more than a trike, but aero drag slightly less with only two tires in the cross sectional area.

    I would like a recumbent version of the Contes Fat tire Quad, with the nice SLA suspension, and a Rholoff as the transmission.

    I did a quick search to see what these were, and wow, that's a lot of weight for a single mechanical disc brake.

    It has padded captain's chairs from a boat.

    the advertised weight is 178lbs, and that's probably before adding the canopy, fenders, etc. with a load capacity of 700lbs that makes an 878lb rolling death trap with one single mechanical disc. All that weight and 20" tires would make for some horrible rolling resistance with any kind of bumps and no suspension.

    I guess they are good for going about the same speed as walking while probably using just as much or more energy to do so, but you get to sit on a cushioned vinyl seat with armrests, and some shade from the canopy. I bet they have cupholders too.

    It's a good thing if it doesn't go very fast.

    The 4 seater is even heavier(913lbs GVW), still with one mechanical disc.

    I beg to differ.
    With lightweight and appropriately strong wheels spaced correctly width wise, I think it might come handy in the post-apocalypse - using the railroad network to avoid using the zombie infested roads.

    I was surprised they didn't use something like this for the South Pole race rather than a trike. It certainly looks like more than 2 wheels was a big advantage there.

    One thing to think about..... a two seater , two pedaler quad would have the same rolling resistance per person as one person riding a two wheeled bike. I think it could have awesome application being used for comfortable exploring especially at Moab. Geared super low for crawling but still have decent top speed. I'm not a fan of the bike saddle high COG type quad. I would go the kart type quad.

    Can electric assist be added? My automotive driving days are finished. I want even try a golf cart. Just built a Schwinn Meridian 26" with 36 volt 500 watt front hub motor.
    Since I live on an island (Mustang, in Port Aransas, Tx.) this would be great for streets in town an riding on beach. Gas Engine assist is not an opton for me. Subject to seizures.

    I know nothing of this, but please do it and post a video of you on the beach. Sounds awesome.
