The Worksman Wheels are mounted.

    Well with working out of town for the last 6 and a half weeks I have not had the time to put the finishing touches on the wheel changeover until a few minutes ago. I did put a few miles on the wheels and I am very pleased with the results. I must first state how difficult it is the mount the sheave on a rear drum Worksman Wheel. I had to purchase the sheave mounting clips for a vintage Whizzer with the 5" rear drum brake. They are not cheap and do not fit exactly the way they should. I did finally get the sheave mounted but I will be checking it frequently to make sure I don't have a catastrophic failure. The other issue was the brake cable adjusting fixture. The stock adjusting fixture is not usable because it puts the brake cable at a very sharp angle and is at a very tight spot in the frame. The brake arm itself is another problem. I was able to clamp it with the brake arm clamp from a Whizzer coaster brake setup.
    It will be much easier to mount the sheave on a Worksman coaster brake wheel. The only modification needed for that is to enlarge the spoke groves on the mounting clips for the larger spokes and use the Whizzer brake arm. The front was much easier but you still have to be creative with the brake arm mounting. Be very careful to make sure you keep the distance correct between the forks. If you pinch them in or splay them out you could have a catastrophic fork failure.
    The Worksman Wheels are a big improvement over the stock wheels as far a strength goes but installing them on a Whizzer is not an easy task to say the least. If you are not comfortable with tools and modifying things you should probably not try this yourself.
    I'm glad I did because it changed the whole feel of the bike.

    HEY WAVY:

    Call Worksman at 1-888-394-3353 and ask to talk to "AL".

    Al told me that Whizzer owners are some of Worksman's biggest customers, and he'll help you with technical details, such as choosing between alloy or steel rims, chrome or black finish, standard or clincher rims, etc.

    I ordered a 26" chromed steel wheel with the Shimano coaster brake, because I'm converting from auto to manual clutch.

    My wheel is really heavy-duty with those 11-gauge spokes...like a motorcycle wheel!

    With the information listed here, I'm going to add this thread to the "Common questions and links to the answers (Whizzer)" sticky. Thanks Jim and Hal!

    HEY JIM:

    Did you mount the NE5 front brake to your new Worksman wheel, or did you order a wheel with the brake installed?

    I'll be ordering a Worksman front wheel later to match my new coaster brake rear wheel.

    Thanks...

    The 77A wheel is a 26"front drum brake wheel. I did not use the front Whizzer brake hub.

    I installed the sheave on my new Worksman Coaster Brake Wheel yesterday...easy as pie!

    I have a full set of toolmaker's pattern files, so I selected a rat-tail file the same diameter as the spokes and opened up the pockets in the spoke clips until the spokes nested pefectly in them, with no "biting" or "pinching" of the spokes.

    I used a #31 drill bit to simulate the spokes (0.120" diameter), and it took about a minute of filing per clip to get 'em all done. (I did stop about halfway through to mix me a Rum & Coke...it was afternoon, so that's OK...)

    Centering the sheave was virtually automatic...the angle of the spokes and the angle and spacing of the grooves in the clip made the positioning correct without even measuring!

    I installed the clips on opposite sides of the wheel, until all nine were in place, then mounted the wheel on Oscar's bones and gave it a spin test. If I had a dial indicator, it would probably have shown a few thousandths of radial runout, but I sure couldn't tell by eye!

    Now I'm awaiting Quenton'e go-ahead to ship him my auto clutch!

    Kilroy will be glad to hear that. He has the same wheel to install on his Whizzer.

    Jim

    PS On another note I was not too impressed at first with the Worksman drum brakes. Now that they are broken in they are much better than the stock Whizzer drum brakes. With the stock brakes I could not stop on the slope of my driveway. It is just too steep for those brakes. Now I can launch myself over the handlebars if I am not careful. They work that much better but they do have to break in first.

    HEY JIM:

    I'm glad you posted that!

    I was just about to ask about the stopping efficiency of the Worksman Drum Brake on the #77A wheel.

    Thanks...

    Hi guys, I would like to put a wider rear wheel on my 24" 2007 NE5 to match the stock 2.125 wide tire. The bike has the 90mm auto clutch, which I will retain, and the band brake on the rear. It would be nice to up grade to a drum brake on the rear but not absolutely necessary (cost). Could you guys tell me what parts I would need and where to get them. This is not something I can do right away, honey dos, but I want to in the future.

    Thanks,

    Randy

    Hal, just a note about the brakes. The Shimano CB-E110 you have on your Worksman has very good stopping power. Today I just fitted a rear wheel equipped with that same brake to another motorbike I recently built, and almost went over the handlebars the first time I used it.

    Good to know...good to know!

    Do you have both Worksman wheels on your ride yet?

    Ren, if you decide to have a wheel built up using a coaster brake (I'm asssuming your band brake is just that) I would suggest using the Shimano CB-E110 which I now have on one bike, and will be mounting (with my 24" Worksman wheels) on my Whizzer when time allows. It is quite reasonably priced. My local bike shop got me the complete 26x2.125" wheel (laced with standard gauge spokes, not the heavier ones) with the Shimano brake for $30. Prices will vary I'm sure, depending on where you shop.
     
  17. How much better

    PS On another note I was not too impressed at first with the Worksman drum brakes. Now that they are broken in they are much better than the stock Whizzer drum brakes. With the stock brakes I could not stop on the slope of my driveway. It is just too steep for those brakes. Now I can launch myself over the handlebars if I am not careful. They work that much better but they do have to break in first.[/QUOTE]

    It sure looks attractive to swap my front wheel with one of these. How much better is it than the Whizzer brake? My stock Whizzer front brake isn't that bad, just would hate to rely soley on it if the rear failed. So is it 40% better??? After break in?? Give it a ballpark % amount better. Sure sounds better than me welding another disk caliper mount eyelet to my springer front end. That's why I have been resistant to the disk change.

    Hi Ren,

    I have a few of the replacement band assemblies in stock if needed. I have both the riveted and glued version. The easiest conversion is to replace the band brake assembly with the drum brake kit, however removing the current hub [part that band wraps around] can be difficult. The Whizzer replacement brake isn't as good as the Worksman drum brake wheel, but won't require buying or making special brackets for the sheave.

    wider rear wheel

    Thanks for the info. My rear band brake isn't a coaster brake, It has the brake leaver on the handle bars and the band assembly is still in good shape. I'm mainly interested in the wider wheel.

    Thanks,

    Randy

    Here's a comparison between the stock 26" Whizzer rim and the Worksman:
