    hi folks!
    my front wheel has developed a loud intermittent clicking noise. Some times twice a rotation, other times up to 4 per rotation.
    At first I thought it to be the speedo cable so I took that off and it still happens.... Any ideas on what it is and what to check next?
    As far as I can tell the tire isnt binding on anything and is running pretty true...

    Loose spokes will click sometimes. Don't tighten too much or too fast. Give the few loosest spokes a quarter turn and see if it helps.

    I've heard wheel bearings click, too.

    spokes seem fine. the clicking seems to come out of the same place (although not sure where yet....) and at different times.
    Just by having the wheel lifted and spinning it slowly it still clicks... :-(

    Take the wheel off and remove the axle and bearings.
    Clean the bearings ,cups and cones and see if there are is any metallic junk on the rag.
    Look closely inside the hub and make sure there are no hairline cracks where the bearings spin. Youre bound to find something, and if you don't it's a good opportunity to clean and re-grease everything.
    I don't specifically know about Whizzers but the front wheel can't be too complex inside.
    Roll the axle on a flat surface and make sure it isn't bent also.
    Keep digging, you'll find it..
    Keep us posted

    The same thing happened on my Whizzer this summer. In my case it was the speedometer's drive unit. The lubricant had hardened and the clicking noise was caused by the drive's teeth jumping out of the slots in the ring. See the attached pic if you're unsure about the pieces I'm trying to describe.
    In my case, cleaning and re-lubing the drive pieces took care of the problem.

    hi Kilroy! That was my first thought I lubed the cable even detached it but still clicked... glad it worked on yours!!!!
    When I get a moment or three i will have to take the wheel off to investigate further....

    thanks everyone for the input!!!

    What Kilroy was talking about is the drive unit the cable screws into. They are very cheaply made and keeping them clean and lubed is very important.
    Good luck

    Yes, that is what I thought and suspected from the start....I am half tempted to just bend it out of the way and spin the wheel to see if it stops ( read too lazy to remove tire at the moment).

    I have a Black 24" panther with a over head valve motor, mine did the same as yours,I took my front wheel off and the front axle was bent, both bearing dry and one had had a bad ball bearing.
    I put it back together and order 2 new axles and 2 hubs with new bearing that were inside the hubs from Whizzer,thats the way they sold the bearings ,already pressed inside the new hub.

    If someone knows the part number of these bearings, you can probably buy them at a auto parts store?

    Hi Tom!
    Seeing that the strong florida winds have blown the bike over twice in the last year there is a good chance you are spot on.
    Were the parts hard to replace?

    Hi Steve,

    No, the hard part is getting them. I could not find any numbers on the bearing, but it looks like a standard generator bearing to me.

    Just take your wheel off, unscrew the axle ,pop out the bearing with a punch, and press or hammer the new bearings into the hub with a piece of 2x4 wood and hammer,make sure the bearings are greased. The ones I bought from Whizzer are only sealed on one side,the outside side of hub, they were basically dry.

    About 98% of the time the "clicking" noise is from the speedometer drive assembly. It is common for the drive to make a noise, and the best solution is to replace the drive. There are 2 options concerning the speedometer drive, one is to replace with the original part, and the other is to use the drive unit from later speedometers. The Ambassador and NE-r use the later style because of the disc brake system [clearance issues]. The later unit is very common and can be ordered from the average bicycle shop. It is gray plastic and has 2 locations for the cable depending on which side of the wheel it is mounted].

    I would guess the cost is under $10. for the later version. Be sure to get the 26" version as it is the same ratio as the original Whizzer version. If used on a 24" Whizzer the speedometer will be off 10% [all 24" Whizzers use the 26" ratio]. If your speedometer indicates 50 MPH it is actually traveling at 45 MPH.

    If your problem is bearing related, the bearings are available from almost any bearing company. If you find it to be a bearing problem contact me for phone numbers of bearing companies that can help supply the needed parts.

    Have fun,
