    Re: Is tilting the answer ?

    Hi Paul.

    I also have taken a closer look.
    You are right, he pushed the cornering too hard by leaning too much too sudden.
    The dust/grit on the road did not help at all.
    I don't think stops...

    Re: Is tilting the answer ?

    Hi Paul.

    I've edited my comment in the meanwhile ;)
    Main reason he fell is the gravel on the road made his front wheel (the only one offering grip/limit tot the leaning) slip.
    He basically...

    Re: Is tilting the answer ?

    Hi Paul.

    He fell over for a very simple reason : the front wheel, which is the only thing offering some grip and limiting the tilting slipped on the road gravel.
    Maybe if there were limits in the...

    Re: Routing cables with pulleys

    You should have no issues with ball bearings on pulleys.
    I've used lathe made polyamide pulleys that went directly on the bolt ... too much friction.
    And i had 8 of them used on the steering so a...

    How to make longer cables

    Hi folks.

    I'm having some issues with cables (brake, derailleur) not being long enough.
    I've tried some homemade clamps but they all tend to slip.

    What do you do to make a cable long enough to...

    Re: Calling trike owners with suspended rears ???

    You only need what you already have and weld "slightly" the spring in one place (no seat post / brace needed at first).
    Support the front end of the boom on something up from the ground so i't about...

    Re: Calling trike owners with suspended rears ???

    Well, since the seat brace/post thing is a triangle, considering the loads (you), one part will be in compression and the other in tension.
    However, the the tension is not large from what i can see...

    Re: Calling trike owners with suspended rears ???

    Hi Paul.

    The 2 ways of making the "seat brace" that you show depend more on how you want to have your seat positioned - therefore how will it load the members.
    You would want to stress the...

    Re: Calling trike owners with suspended rears ???

    Willy M is correct.
    I was trying to simplify things for Paul since they are somewhat confusing.
    Guess i over did it.

    Emma, yes, more travel but that's irrelevant.
    If the end result is the same...

    Re: Calling trike owners with suspended rears ???

    Paul, you can make an adjustable mounting for the spring, just for testing or permanent.

    In your config, making it to adjust the leverage won't be easy peasy but not very hard either.
    Think of...

    Re: Calling trike owners with suspended rears ???

    Paul, Cambiker.

    Whenever you combine springs, you affect total spring length + travel and spring rate.
    This depends on the type of combination - series or parallel.
    In series:
    - total length is...

    Re: Calling trike owners with suspended rears ???

    Paul,
    If you want to have the spring in a horizontal direction while the wheels go up and down, you need a system to change force direction.
    The most simple and most performing is a simple...

    Re: Calling trike owners with suspended rears ???

    Hi HHJJ

    For most people that only have to pedal on proper roads with bike lanes, handling the odd pothole, a soft seat with balloon tires might be enough.
    But if the roads are cubic stone, or...

    Paul,

    Sorry if i was too cryptic, not a native speaker / thinker.
    Spring direction does not matter as long as framing can direct forces in such a way as to operate the spring (push or pull, most...

    Re: Calling trike owners with suspended rears ???

    Stormbird,
    The springs on bikes used by "ordinary" people are about 650LBS around here.
    I've had 2 child bikes, 20" wheels, that used 450LBS springs.
    The market has only 850LBS springs for sale...

    Re: RPM tachometer, cadence meter

    Ok, so this one looks better.
    Here the oscillator seems to be the R14, C2, C1 group.
    And it runs on 5v like you wanted ;)

    Re: RPM tachometer, cadence meter

    Allrighty then.
    On the left there's the 7805 - a standard 5V regulator.
    It has 3 pins: input, ground,output.
    For input between 6-30V output is always 5V.
    If you just have 5v, connect those 5V to...

    I've looked around and all the luminous ones are made for high rpm (car / motorbike).

    Your only bet is to use the highspeed one shown in the first post with either the following:

    So you want bright display (LED) large enough to see, in the proper rpm range and not break the bank :juggle2:

    Honestly, the 10 magnet thing is WAAAY better from this POV.

    Remote steering options for a LL fork

    Hello builders.

    I used Leading Link front fork with scooter coil over shock suspension.

    For that kind of terrain, low COG, you and the dog in the back, the regular Timberwolf rear suspension is enough.
