    Tandem Trike Fat Bike

    I know most of you have seen a picture of my trike floating around the internet, so today I decided to take a few pictures of it.

    The frame is a late 1970's Worksman Tandem Trike, made in the USA of course! I reamed out the 1" headtube to handle a 1-1/8" fork and headset. The rear wheels I had to use the stock hubs with spoke washers since the original spokes were the thickest gauge I've seen. 100mm rims with 4.0" tires all around, beer cooler in back, AirZound Air Horn to scare people with (ha!), the front hub used to be a drum brake and I replaced it with a disc, now this thing can do simultaneous front & rear wheel skids that stops crazy fast with 2 people on it. The fork is a Moonlander fork.

    It actually doesn't ride too bad in the packed snow on the streets. My wife and I use this to ride down to the local ale house, keep in mind South Dakota lets you bike intoxicated legally and the bike path near my house almost goes straight there, perfect combo!

    Should I be worried that the first thought that jumped into my head was "I SO need to move to South Dakota"?

    Lol! If you are a big Mountain Biker like I am, the Black Hills, where I live, are amazing (think Mt. Rushmore).

    Love It!

    Have you seen the Trykit Axle assemblies? Lightweight Racing and Touring Tricycles and Conversions

    It was pics of your build that inspired me to study up on trike differentials/axles. The Trykit is pretty interesting. It uses a split, double freewheel that works like a limited slip differential. True two wheel drive when you going straight, and the bound wheel slips when turning.

    Just awesome. Well done. Way more jealous of you than I am of anybody with a carbon fatbike.

    Fat tandems seem only so useful because the tires are trying to spread out about twice the weight, so I bet the extra tire helps quite a bit with snow ride ability.

    Nice
    EDIT in fact, the bestness of this bike exceeds my comprehension.

    What's the gearing of that beast?

    Yeah I remember talking to you about them. Those kits cost a little more than I can spend on the trike but cutting the axle, adding a freewheel and for the axle might be more doable!

    Glad you like it, I was keeping the goal of the project a secret while doing it. But now it's been finished for months just never got a chance to post some pictures!

    Haven't taken it in deeper snow but so far so good! The trike is definitely 3 times the fun, ha!

    The gearing would need to be calculated, there is a change in gear ratios to the back crank, I'd have to say it's close to 2.5/1.

    The original wheels were 24" now there are 26" wheels that are as big as a 29, so the gear is even harder. Maybe I could get a gear/inch measurement tomorrow.

    No doubt eah? Would it be possible to source/locate a chest/cooler to match the era without being uber heavy?

    This thing is so cool! It would also make a perfect summertime beach bike!

    I winder how hard it would be to make a front end with 2 wheels? Like a quad...

    My son w/Autism has a trike, now I regret selling my Pugsley fork.
    His has 24" wheels so the On-One baby fatty wheels would work.

    Only downside I've noticed is the larger the wheel size on trikes, the scarier cornering is. That thing must be a real bear to keep rubber side down with one rider. Must get real exciting after a few beers!

    My 34 year old son also has autism and never rode a bike before. I took a 20" three speed Trifecta Worksman with a 36v ebikekit front wheel drive in trade for a 26" Crystalite 48v MTN bike. I really didn't expect too much. However, for the first time in his life, my son loves to ride a bike. I can't keep him off of it. Everybody loves it too, kids and adults alike. Most popular bike in my shop.

    I think you need another coil-over back there. Dayum, that thing is cool!
