    tadpoles that fold for storage and transport that also have a coupling option

    Was considering tapole trikes for myself, wife, and handicapped son because they fold for storage and transport in trunk and/or back seat of car. Also need coupling option for my handicapped son. Am told that there are no tadpoles that fit these two criteria and that deltas that do not fold, Greenspeed Anura and Hase Kettwiesel, are the only ones that have a coupling option.

    Are there any aftermarket coupling options for foldable trikes?

    Now that I think about it, the tadpole design probably does not lend itself to this application. On the other hand the back wheel would be just as easy to take off as the front wheel. Appreciate any comments.

    So far as I know, nobody has figured out how to link 2 tadpole trikes together yet and even folded they take up a significant amount of space. My wife used to have a Greenspeed GT3. We bought it because she could fold it and fit it into her compact Saturn by herself but there's no way you could fit two into there.

    We now own a pair of Kettweisels that we link together. We can fit both of them into the back of our Honda Element (with the rear seats removed) but we have to shorten both booms so it's about a 15 minute job to make both trikes ready to ride. The two Ketts, with booms compressed, completely fill the cargo area of our Element. I had to buy a couple of additional soft sided duffels that I can fit into the nooks and crannies to carry on our vacation this summer. There is no room for a conventional suitcase. Home storage of the Ketts isn't too bad because they stand up vertically. There's even a "kick stand" peg on the back of the seat to make standing on end easier.

    The good news is the Ketts feel rock solid to ride even linked together. Each rider can pedal at their own rate and select the gear ratio that suits their peddling style best. I would think that, for your family, it might be a good solution for riding together. Not cheap, though.

    Before we made the decision to buy the Ketts we went to the Midwest Recumbent Rally in Stevens Point, Wi. so that we could test ride a Kett and an Anura one immediately after the other. We chose the Ketts because we felt the handling difference was so pronounced that we wouldn't be happy with Anuras. Either way it's a pretty significant investment so it would definitely be worth your time to arrange a back-to-back test ride somewhere.

    Thanks, retrogrouch. I assume the Hase's had the differential option.

    I am also wondering why there are no front wheel drive tadpoles?

    Differential is an option but it costs more. Ours don't have them and, at least so far, I haven't missed it. Actually, Hase has lots of options but they are real proud of all of them. The hitch for coupling two to make a tandem is around $200.00.

    A front wheel drive tadpole could get pretty complicated with steering and universal joints and maybe a differential.

    fold , HP Velotechnik has two .. http://www.hpvelotechnik.com/produkte/index_e.html


    Are there any aftermarket coupling options for foldable trikes?
    contact a custom frame builder for a retro fit, S&S, Is my guess..

    IDK about Aluminum compatible S&S fittings. most builders use Aluminum ,
    as people can judge and measure weight easily..


    [Def: 'tadpole' 2 steered front , 1 rear drive wheel, 'delta' 2 rear wheels ]

    Another option you might want to consider is the TerraTrike Rover. While it does not fold, it is available with several drive train options, it is easily disassembled into several manageable pieces for transportation and on top of that, TerraTrike also offers a tandem attachment that allows you to convert a standard Rover into a tandem. Couple that with their IPS (Independent Pedaling System), the tandem riders can pedal at their own pace without affecting each other. You might also like the pricing on the Rover; hard to beat. Here are a couple of links for you to look at: Rover spec sheet: http://www.terratrike.com/rover.php Rover tandem attachment: http://shop.terratrike.com/Rover-Tan...p/tt800046.htm several videos of the Rover, how it can de disassembled and how to add the tandem attachment can be found here: http://www.terratrike.com/videos.php

    A Hase Trets on the back of your tadpole would work. IIRC they do have an adapter to use with a regular hub hitch (like a trailer hitch) so you could hitch it up to any bike/trike you like. Voila:

    Thanks a lot guys. Lots of great ideas and insights.

    Went to a local dealer and rode a tadpole Greenspeed GT1 and a Hase Kettwiesel, and then rode coupled Kettwiesel All-Arounders with my handicapped Son and also my riding buddy came along.

    Found out that my Son really enjoyed riding so this is very promising as a family activity and he also pedaled appropriately, so well in fact, that I would now consider a dedicated tandem.

    After riding a tadpole and delta not certain but would almost consider a delta over a tadpole now that I have had some experience. Would have to do some more research to get the differences straight and then ride them again. The coupled Kettwiesels rode great. My buddy wants to ride them coupled on the Ride Across Indiana instead of riding our diamond framed bikes.

    He offered the 2 Kettwiesel All arounders,and the coupler, for $6,700. Appears to be $1,000 off list? Good price?

    Central Indiana is very flat but I think it would be prudent to add the triple option, $379 to one of the models. Also want to add the fender bags because although not likely, don't want to take any chance that my Son might drop his hands down and get them caught in the rear wheels of disc brake rotor. Besides, need ability to carry tools and spare tubes/tires for roadside emergencies.

    No opportunity to ride an Anura unless I travel significant distance. Read specs and if I understand correctly the Anura price is less, smaller tire, different front gear changing mechanism that I am not sure I understand, triple instead of single chain ring, and rear differential is standard. Appreciate handling observation but Anura seems attractive spec wise.

    Appreciate any more advice and observations that you guys can give. Wife and I both think it is a lot of money but it would be worth it if my Son enjoys it as much as he did on the test ride and sticks with it. Really need something the whole family can enjoy and get my Son some exercise and fresh air. Would also be really important if he could eventually ride the trike as a single, if only around our neighborhood, for something that he can do independently as possible.

    Did not give details but my Son is 18 years old, 5'6", and 110 lbs so appears to be too big for the Hase Trets does not appear to be an option? He suffers from Epilepsy and is on the Autism spectrum.

    No nothing about Terra Trike but there is a local dealer so will contact them.

    At 5'6" he'd be too big for the Trets- but coupled Kettwiesels would be a great set up. You'd never be sorry getting a triple (even where it's flat). That's a good price for a trike that usually goes for $3500+ bare. Ask about a harness (I know Hase makes them). It'll keep your boy in the seat in the event of a seizure.

    Very nice!

    One advantage of trikes that are coupled instead of dedicated tandem is that it's usually easier to transport two single trikes than one tandem. If that's important for you, keep that in mind.

    You mean like the Sidewinder?

    David Bruce is also working on a FWD recumbent trike design.

    A friend got the trident trikes, the model is stowaway that can be folded when the seat is removed.

    DSCN1008.jpgDSCN1009.jpgDSCN0999.jpgDSCN1016.jpg

    The hinge is slightly slanted so that when it is folded, the rear wheel clears the crank and pedals. When folded he is able to load it into the back of his Suzuki Swift. The stowaway I is US$1499
    and the stowaway II is US$1699.

    On Saturday morning I am taking my wife over to ride the Hase Kettwiesels. She is warming up to the idea. Even suggested we should get three to couple together and even inquired if the dealer had three. I was toying with the idea of getting a single tadpole for a third trike to ride solo. Get something fast that I could ride by myself sometimes and we could take turns riding with my Son. It appears I could get a hitch mounted rack to transport two but three would require a roof rack. Hoping to get a folder that will fit inside the car. Lots of money but would be worth it if we can do this together as a family.

    Wife enjoyed the trikes and I really liked riding with her again. Talked ourselves into purchasing 2 kettwiesels. Emailed the dealer over the weekend and waiting for a reply to determine pickup or delivery. Want to wait until we get the over the fender bags that will prevent my Son from getting his hands in the rotors or wheels. Might ride with my wife in the meantime. Looking forward to having lots f fun.

    What dealer?

    Kettweisel has TONS of adaptive accessories for various needs. I've had nothing but good service from them so far, even when stuff had to be shipped all they way from Germany.

    Hope everything works our well for you.

    . My 15 year old daughter with Down syndrome and arthrisis is interested in trikes and we have considered the Hase Trix. Hoping our insurance will help out after her Doctors perscribe the trike. Just wondered how it is going for you guys when in tandem?
