    Homemade Throttle Lock

    The recent long road trip discussion got me thinking about a throttle lock. Here is my freebee homemade and improved throttle lock.

    Made out of 3/16" thick HDPE plastic. Used a heat gun to heat the plastic and form into shape.

    Advantages over a store bought throttle lock:
    Cost less, used a piece of scrap plastic, cost = $0.
    Adjustable clamping force by changing rubber band.
    Offset arm provides more room for hand on brake.
    Easier to set with index finger.
    Ratchet action makes it easy to set and release but hard to engage unintentionally or by gravity.

    Maybe the only disadvantage is that many folks will not have any HDPE plastic laying around. Maybe some other plastics that can be heated and formed into shape would work just as well.

    Seems to work great.

    How would I know if I had some HDPE laying around? What kind of things are made out of them?

    Would a plastic coat hanger work?

    Not really any different then a cruse control. It keeps going till you turn the throttle back, a normal reaction when you want to slow down.

    Many things are made of HDPE from tupperware to water, sewer and corrugated culvert pipes. Just a matter of finding some that is about the right thickness size to use. Any thermoplastic should work. A thermoplastic gets soft when heated and harder again when cooled. Items that are marked with a recycle number of 2, 3, 4 or 5 should work.

    Other polyethylene items are plastic barrels, lawn furniture, plastic reclaimed lumber, electrical and plumbing boxes, some water, natural gas distribution pipe and many more.

    The free play on my bike brake lever when I got it was about 1 1/4" and if the lock was in the wrong place the brake lever would contact and push the lock out of the way. I adjusted the free play correctly and now the brake lever does not come close to the lock when fully engaged.

    Go to a "Dollar" store or Harbor Fright and look at the small white plastic "cutting boards" they sell cheap.
    I think they are polypropylene plastic, might still work.
    These little cutting boards have many other uses on bikes & around the shop!
