    Hi all and thanks in advance for any tips or ideas. I have a few bike frames kicking around and what I would like to do is build a trike using what i have kicking around.
    Anyopne built a trike out of a 2 wheeler or know of any good links on same?? Funds are a little tight right now so cant justify buying a kit but have lots out material kicking around ,. just need some ideas.
    thannks again

    i assume you have torch & welder?

    do you have 2 matching frames you can work with to build the back half?
  3. Haggard

    Haggard Guest

    Yes, i have two mountain bike frames i could use for the back and a full suspension will work good for front,if i make it rigid , i havent a welder but have bros that dont mind helping out. Would like to make it posi but even if i run 1 wheel from pedals and other from motor would be alright for now i think until i can afford a proper rearaxle kit or something similar.
    i wonder if a guy could make make use of 1 out of a garden tractor or rideon lawnmower with a little mod??

    Not really into recombents.
    Want to motorize something along these lines.

    Here's a few trikes I found interesting .
    Notice the center of gravity on the first set compared to the second set

    now these ones


    and a couple unique


    Sorry if i'm posting to many. Delete if neccessary. What i'll do is post all the trike pics ,gotta be close to a hundred now,lol on my space and post a link.instead of taking up so much resourses here

    Wow just put them in seperate folder ,198 trike pics!!

    nicely done & properly placed pics are no problem, we prefer to have the data onboard :)

    just make sure to mix a few engines or motors in there once in a while :p :lol:

    the long recumbent with the ice cream cart or whatever would be a perfect "landspeed" candidate for that yamaha 4-stroker i just snagged from wavygravy :evil:

    What size is your yamaha 4stroke?
    I've a Honda 125 4 stroke off an elite scooter that has a cvt built in that did 60 mph on the scooter and will rip on a bike. but is faily large in size to mount hence the trike .
    Now have a gander at this bad boy. its attached with torsion bars and wants to stand up straight , but can be manipulated through corners by the rider.
    Really don't like the trike style at all but the leaning features incorporated in to a different style trike would be awseome don't you think.
    Man, i'm intrigued!! this thing could fly. : )

    Well, a little slow getting started on this one but i got a good idea where i'm headed with it now

    by using a full suspension frame that I had motorized for awhile last summer,I simply removed the rear shock to rake the front end
    oh and the honda seat is just to give me reference on the hight i want it's not staying lol
    and I've enough pedal clearance , I can drop the backend down abit more and add a few more degrees of rake
    gonna run disk aswell as caliper brakes on the front to one control and calipers on both back ran seperately to their corrosponding sides to use as steering aid which gives me 3 brake controls and a throttle which i havent quite got laid out yet.
    Wonder if I could use a twist throttle on both sides , one for throttle and the other for front brakes. dont think i'd have enough leverage with it to activate 2 sets of brakes but might be worth a try??? for lack of a better idea right now l;ol

    check this little demon out!!!! 65 cc pushing 15 ponies with a 6 speed trannie and wet clutch wooohoooooo!!! man i need,,, I mean ""NEEED ""one of these

    Haggard- (or anybody else with Trike experiences)

    PM me your e-mail, a customer of mine has done a lot of research on potential tricycles, sent me an e-mail with a BUNCH of links, pix and info, which I hope you could incorporate into THIS thread. 8)

    I could foward that e-mail to you, I want to learn more, but you guys have the head start, it would be so much better to follow ya'lls advise.

    Tricycles will become very important in the future as retirees get interested, and if we could get a gallery together, it would be VERY helpful.


    I'll post that pic that Papa provided, which another customer is looking to develop for a possible solution...

    looking good , so far.

    I'd like a peek at some of your drive train research.

    your live space is down right now...I'll check back

    Just checked link and is fine now.
    check out all 3 albums almost all bike(trike) pics( a few I got from from the gallery here) hope noone minds , and a couple pics of my computer room which I think is close to where i might or might not say it's done!!???!! heh heh

    Couldn't resist adding my "three cents". Here's a trike I played around with for a while:
    Started with a regular Schwinn, upsized the wheels to 26 inch (unfortunately, used the 28-hole hubs which just weren't enough in back), traded out the "girl's" frame for a "men's" (almost needed a step stool to get on it, you just don't realize how much you lean a bike over when you get on it), electric motors on front wheel from ebay, battery behind seat. Rode "like a cloud I tells ya", easy to forget you were on a trike until you even THOUGHT about a turn. Ever see pics of sidecar racing?

    wow, very nice schwinn . got a nice cruiser frame still aswell but thought this hunk a junk suspension frame would be more worrkable for what i was trying to create and want to Sttrrettccchhhhh this cruiser for some reason
    Yeah ,some crazy fellas back then .
    I think it would be a little beyond me at the moment to try for a leaning trike.
    Just can't get a handle on it.
    Been trying to picture it with a universal joint of sorts but stiffened up. just can't quite picture it .
    so what i might try for is a seat that could be manipulated from one side of the trike to the other to shift your body wieght while cornering. Haven't seen anysuch thing yet so maybe it's a rediculous idea but i think it might be worth a shot. Would have to be on some kind of an arch i think . arched high in the middle so's you could hold it in the inside of the corner against the centrifigal force. or even if a guy had a vertical seat post hinged at the bottom , it would make its own arch as you leaned in.
    Input anyone ??!!!?? lol
    would need stoppers to limit travel and stabilisation of some kind but might be workable

    Low, low, low

    It'd be a lot easier to just keep the center of gravity low. Use smaller wheels and mount the motor just in front of the rear axle, or wherever you could get it the lowest. :wink: You could always just fill the tires with water or sand or something.

    Or, you could always use car wheels...

    I have a pair of 15x7's here that will one day find their way onto a motoredtrike ;)
