    I finally recieved the tadpole trike for my next build. The other things I'm playing with have been killing time while I waited for this. I'll keep working on them, but this is the priority.



    The engine is sitting in the auto shop at work. I'll get pictures of the components all in one place tomorrow. I'll probably ride it around a bit before I start cutting it apart. I've already noticed that the steering is quick enough that, with an engine, this may be a dangerous machine.

    I will stay tuned to this build van.

    Do you think changing the pivot point would offer safer steering? Just a thought.

    Pete, If it's not something that I get used to as I ride, I might look into changing to indirect steering. I could adjust the steering ratio then. It's common on tadpoles.

  6. Tadpole trike Damaged in shipment?

    HI Van, I like the color, but you might want to check out this one thing I see. That long straight beam on the bike looks to be really bent almost into a crescent shape?

    As big as that tube is I don't think having the chain too tight would bend it like that. Was the shipping box ok?

    Mike, That's the way they are made. My pics may accentuate it. The curve is necessary to get from the back wheel, under the seat and up to the pedals. The tubing is heat treated after the welding/bending process. It's comfortable. I adjusted the seatback down a bit, and it's like sitting in a lawn chair. Where I live is pretty scenic, and with the trike, I don't have to stop and park the bike to take a picture. I just stop, relax, and shoot. One observation, I have one leg that's a couple of inches shorter than the other (a rather uncoordinated, but highly spectacular motorcycle dismount), and though it never made a difference on a conventional bike, it makes a difference for adjusting pedal distance on this.

    Okay, here's the parts for the trike. I will have to have some things fabricated, but this is most of it.


    Anybody got a shoehorn?

    Gratuitous scenic picture. Sagway is up in that right-hand inlet.

    That Lifan engine assy has a transmission...don't it? You better have a **** fer stout rear wheel. :D

    It has a CVT. I'm talking with The Wheelman about getting one built with 10g spokes.

    Wow, Van, looks like a lot of machine for that little tadpole. I bet that felt weird the first time riding it, huh?
    Now thats a first for me, seeing white sand beaches in Alaska! :smile::shock:
  11. Alaskavan

    I wish it was sand. I looked outside this morning and saw dry pavement. I thought, "cold, but ridable." I jumped in the shower, got clean and dressed, looked back outside, and everything was white.

    It's amazing how well that little 1/4" reflective stripe on the tires shines, eh?

    I like the reflective strip, it will be safer for you at dusk even
    (that will help, now you will be so low to the ground)
    nice b-day present to yourself btw :lol:

    The trike is comfy, and it corners more like a gocart than a bike. The tadpole style adds something too. I was coming up on a driveway that I wanted to turn into, but the corner was a little sharp for steering. I just locked the front right wheel and made a 90 into the driveway. And I have a 5 LED light on the front (enough for a non-motored vehicle) and a couple of flashers on the back. I promised the chief of police that I'd put a flag on it too. He thinks it's cool.

    Thanks guys.:grin: I feel like I'm growing younger.
  17. Unbent 'Bent

    Hi Van I was just funnin ya! no-way it could have been bent that much, and still stayed "inline" with itself!

    On another note, hyperextending knees is real bad business, are you considering "Pedal Blocks" on the one side so you can equalize the pedaling function, and take potential stress of of your hips?
    The older we get, the easier we break (and wear out parts)

  18. Dockspa1

    Thats a great point Mike! Van maybe you can find a thicker pedal for on side and yet not noticable. I had to wear a rocker bottom sole boot on one side so, I sorta know the feeling Van.

    Thanks for the suggestions, but I won't be pedaling hard very often. I just shortened the boom, I don't get full extension on one side, but I'm not racing anyone. I passed a bunch of kids on a field trip this afternoon. Mayhem broke out. They think the trike is way cooler than the motored Mtb. I wonder what they would think if they knew what I'm planning to do with it? When I bring it out in public with the motor, I plan to have a rear fairing that will hide it, and I don't plan to ride it much in town. It's for the commute to and from Mosquito Lake.

    Can't wait to see the procedures in the operation room on film.
    After that long wait, Van, I bet it scares you to start the disection.
    Doc :smile:
