    I have a Golden Eagle setup I got together, though I haven't rode it much yet as the weather's been bad (IL winter).

    I though about doing this all summer long and when I finally decided to do it, I went to buy the bicycle I wanted (Rans Fusion) and it was backordered a month. So it all got pushed to later in the year than I had hoped, and I don't like riding in cold weather if I can help it. So I don't know how much I'll be riding it until springtime.

    One thing I noticed about the drive ring is that it keeps a lot of tire pumps from fitting on. I have presta tubes but I don't know that schraders would do much better..... there's only a few micro-pumps that will fit, did anyone else notice this? (-I didn't have any other problems that weren't caused by the oddball bike choice-)

    My problem with pumps was I chose the cheapest one to take on the road with me, and when I had to use it on the Florida trip, but it would get me enough to get to the next service station, to purchase 50 cents worth of air.
    My bike shop showed me Pesta, and I knew that would not give clearance under the ring, but I've never had a problem with Shraeder.
    The "bicycle meditations" after that Florida trip (which was the warm-up for the Denver trip) made me interested in trying to build the indestructible rear tire/wheel/tube. I described it somewheres else in the forum.
    But I was new to the whole "bike thing" last year, I had to go through Avalon/Huffy/Schwinn and WesternFlyer before settling on the Sun Cruiser models, and the feature I liked best was that it had the fattest tires as standard equipment.
    Anyway, welcome to the forum.

    Nice work & webpage. I liked the Episode 5 Gas vs Electric. I could cause alot of drama on the Tidalforce page with those comparisons & probably will! I can only speak for myself & say there is no comparison and that e-bikes are overpriced pains in the arse. For me-- the battery technology just isn't there yet-- not to mention I kinda like the fumes & a little noise.

    DBR :twisted:
  4. the main reason I got the 2 stroke is $$$$$$$$
    I can't afford $400 for the setup with the li-ion batteries,
    $300 is a tease with the giant lead-acid batteries.
    $200 for a gas engine $100 on replacement parts for an old junker bike and it's a sweet ride.

    You forgot to mention going less than 15 miles on a charge and going no faster than 20 mph if you weight is less than 150 so goinggrocery shopping would be out

    GEBE Comments

    Were included above in GEBE "Sticky" above and maybe should have been inserted here or in one below???

    This was an early post, back when we were just getting acquinted with Tom's new forum setup, then Augie's active moderation (I think it was before we knew how to upload pix).

    I'm about 170 pounds, and the smallest engine has carried me thousands of miles, but I am STILL in the minority, the GEBE's that have arrived thus far are mostly in the 35cc category.

    So, just like the early days of the forum, I'm still learning about stickies and a clear way to organize the discussions.

    NOTE TO EVERYBODY- I know zilch about any other system besides GEBE, I found out about them in a 2004 Popular Mechanics article:

    I understood the premium pricing for the mileage acquired, and have personally tested the endurances.

    AND I found a bike shop/Snapper dealer who takes care of both parts of my equation. I will slowly gain "engine knowhow", but I haven't even had to change a spark plug/air cleaner yet !!!

    Anyway, I think folks over 200 pounds should look at the 35, and folks under 199 pounds can get there as fast, or faster and quieter, using the 25.

    I am clocked constantly and consistently at 33-34 mph on the 25cc., both by neighbors speedometers and those flashing speed warning signs.

    Anyway, I'll put a sticky up for each type of engine, and then common ideas and topics can go below the stickies.

    Once more folks arrive, we should have enough experts to answer all the questions.....

    Yes, I think you have got it

    right there.

    I am on the cusp with winter weight at 210 and fighting weight at 180.

    Need sun...still, the 33 Tanaka may be best of both worlds, but I love that GX25. When I return from Springfield tournament, will make decision.

    Need all advice I can muster.

    I ended up with the little Tanaka, but as of 5/11 have yet to mount it and run it. Will post pics etc when I do.

    Doug's observations are very interesting. Got to hand it to him, powering a Rans CF (Crank Forward) is very mod. I bought used Burley Sand Point and put the Tanaka on the back to go up hill. Plan to pedal mostly, but it is nice to know I can flip on the power when I want to do it.

    Lots of insight from Doug on needs for suspension frames etc to consider when buying a bike. I agree too that 20 - 25MPH is about tops, if not too fast, and very tough on frames, not to mention a person's bod.

    I've got a Worksman on order for the GEBE kit.

    I ordered it off the website, they charged my credit card and I didn't hear anything for two weeks..... So I phoned and asked, and they tells me that the typical delivery wait time is 30 to 45 days.

    I haven't put anything new on the website because the engine's just been sitting.

    Hey DougC,
    I'm really anxious to see a Worksman installation because I have one too. Did you order the one speed and does it only have the coaster brake and have you considered adding a front caliper brake?

    Guessing (and hoping) you'll start a new thread for your conversion. Mine is a used Worksman, (my Hum-Vee). I bought it last week but haven't started reconditioning and have'nt ordered my GEBE kit yet. It's a one speed and rides nice. I believe it only has 1 inch spoke to frame clearance (s/b 1-1/4") but will get an accurate measure when I align the wheels.

    BTW, I enjoyed reading your blog about your Lans conversion but I need to go back to see which GEBE kit you have. (Edit: just spotted it in your handle-DOH)

    I ordered a 3-speed coaster-brake with a front drum brake. I figured I *might* have to pedal it home at some point, and I am moving to an area with mountains, so I really wanted two different brakes on it.

    I had no way to measure if the spoke ring would fit, I really hope it does. I'm guessing I'll modify ithe frame if it don't. I've got nothing else to use the bike for.

    I couldn't find anyone who'd ordered one off the site direct. Many people seem to get them from industrial surplus sales, so they don't get to pick exactly what they want.

    Holy smokes...... :shock:
    Assuming the UPS truck is on time, it's gonna be exactly two months from order until the bike arrives. I placed the order 4/30 and the tracking number says billing info was received 6/27. The actual transit time is only three days.


    Assuming the bike is as good as I've heard, I had planned on ordering another one for regular (non-engine) use--but that will be some months off, after I have relocated. Should be entertaining to see how long that one takes.

    This all American business has been making bikes for what?? a hundred years?? You'da thunk they would know how to make and ship in a coupla days and compete like the younger companies have to do.
    Go figure!!

    Got the bike in today.
    Right off, it looks like the GEBE ring will NOT fit inside the Worksman frame, as-is.

    The seatstays seem to have just about enough room, but the chainstays do not--you need 1-1/4" of clearance, and they only give about 1". I may try jacking it, haven't decided yet. I wanted to ride it with no engine for a few days anyway.

    Towards that end, the cockpit is rather short for a 6'2" person--the 1" quill stem only extends an inch or so forward, and doesn't have much of any vertical adjustment either. I plan to get another taller & longer stem for it already.

    Overall it is rather heavy, but much of that weight is in the wheels. The spokes are HUGE, they're easily twice the diameter of the "regular" bikes I have. You can't even try snapping the normal spoke ring on, I'll have to drill out the slots bigger or something.
  16. Worksman Rims and belt sheaves

    Hi i don't know anything about GEBE.
    BUT I do build Whizzers, with belt-drive sheaves, and use Worksman wheels exclusively.
    Whizzer sheave bouls wonderfully to Worksman, what type of drive belt will your engine use?

    Re: Worksman Rims and belt sheaves

    I already have a Golden Eagle kit.
    The sheave is a plastic molded ring that has keyhole-shaped slots cut in it to properly snap on to either 32- or a 36-spoke bicycle wheels.
    I'll have to email GEBE and ask if anyone has done a Worksman this way.
    A few possible problems I notice:
    ...the 3-speed rear hub doesn't have a lot of extra axle to play with. It's hard to tell how much room there is to put on the engine mount. I know that you can get longer axles for single-speed hubs, but I don't know about a 3-speed.
    ...the front wheel looks like it might have enough clearance for the sheave inside the fork, but I got the front drum brake wheel. Because of the drum brake's diameter the spokes cross farther out than usual, and they won't come close to fitting into the regular cut slots.
    ....The spokes aren't drilled on the centerline of the rims. On the "downhill"/MTB rims I have on one bike, the spokes are drilled about 1/16" apart, on either side of the centerline. On the Worksman rims, they are drilled about a quarter-inch apart. This seems like it would push the sheave out even further than normal, with respect to the engine mount.

    ....In general--the front drum brake needs help. It barely stops at all, I have to open it up and see what's going on in there. Also the cable stop is super cheap and slides if you squeeze the brake lever very hard. The drum brake has no brand markings and looks pretty crude, so Worksman may have made it in-house.
    ....The rear coaster-brake makes scary grinding noises when stopping... I don't ever remember new coaster-brake bikes making such a noise, but it's a Shimano Nexus, so I'm guessing it just needs to break in.
    ....I shoulda got the 12" hi-riser handlebars! The regular ones put the handgrips about 2" below the seat. I'm used to my recumbent bikes! Agony!!!

    Hi I've used a bunch of worksman wheels with the shimano, mine dont make any noise, open yours up and grease it good, Mike

  20. belt specs

    Hi well I dunno what that means, we use Ax type fracional hp belts is that what yours is or is it some toothed belt like on a cam or blower? Mike
