    Well my kit came. I wanted to put it on my mountian bike but had
    frame clearance issues. So I dusted off my old ZAP bike and now I
    have the Prius of MBs. LOL. Gas for the road and electric for the bike paths.
    Here it is!!

    way to go, outstanding! how much does it weigh? if you could power a trickel charger while on gas it would even be closer to a prius. congratulations! call mechanix illustrated, they might do a spread.

    please, i am serious about the magazine!! your idea could turn on other ideas and people in the thousands. just submit some good pics. with an explanation and approximate cost and benefits. you could be the next poupil pocket fisherman, and you only need sell plans. wat an oppertunity.

    Dude that's awesome.
  7. Will the Zap motor charge your battery when your GEBE is running?
    This is an amazing example for it doesn't look at all bulky.

    Thats an excellent TRIbrid you have there. If you coordinated controls between leg, gas, and electro power that thing could accelerate like crazy, uphill would pull really hard too.
    I would bet with the right brushed electric motor and controller regen is possible and probably fairly easy to mod.
    I like it MORE PICS!

    Boy, howdy!

    I like the way you think. Got me too brainstorming something fierce. Why not take a mini-generator, say the Briggs & Stratton 1532, and stat modding? Decouple the generator from the engine, swing it thru 90 degrees, mount it to a common baseplate, with an electromagnetic clutch mounted on the engine crank, to a same size pulley on the generator shaft? This allows the footprint to go from being an elongated rectangle, to being basically square. Frame it above the generator so you can mount a jackshaft, second electromagnetic clutch on the engine crank out board of the generator clutch (switched so that one or the other, but never both clutches) can be engaged to drive a jackshaft (maybe make the jackshaft from a modified Shimano 3-speed hub), then either chain drive to your rear wheel, or whizzer drive? Set up one of those RC type high power electric motors e-clutched to the jackshaft for when you want to use strictly electric drive, with LiPO batteries to maximize power density while minimizing battery weight.

    I bet it can done for about a 40-50 lb weight package, and a dimensional requirement that will fit in a slightly stretched bike frame.

    SimpleSimon that doesn't sound very simple :p

    You could take a mini-generator and put it in a trailer. Then just run wires up the stalk of the trailer and power the electric motor. Even running on low the gennie will put out enough amps to run the motor and charge the battery. One of the honda eu1000i inverter gennies would work well b/c they make DC naturally then invert it to AC, just hack the DC portion off.

    I pulled a 120VAC motor out of a cord powered weed whacker. It is rated at 4 amps at 120VAC so 480 Watts. That should be about right for a bike. With a Honda 1000W generator on the back putting out 120VAC, it might be an easy, just plug the cord in hybrid. It runs at 9000 rpms so it might need a jackshaft. I have run it on the workbench in a vise, it has lots of power when plugged into house electricity. It is pretty light in weight too.

    Maybe im wrong, but could you hook a electric hub to the front wheel and use it as a generator for the battery pack while cruising on gas?

    Well guys, I hate to admit this but I pulled all the electrics off.
    The differance between the gebe kit and the ZAP stuff is to large.
    I dropped 21 lbs getting rid of the 12mph, 10 mile distance dead battery.
    Zap does sell a duel motor kit. If I had that I might have left it on.
    As it sat, the friction drive motor did charge the battery.
    Three hours of gas time scrubing with the zap motor will charge the Battery.
    It just was not worth the weight.

    However as eljefino had mentioned, If the gebe turned a small generator instead
    of a clutch and it ran a good electric motor (20mph) or better it would be like a
    modern freight train. The most efficent way to move things.

    anyone want to buy a full ZAP setup? LOL

    Thanks for all the comments guys!

    I think it was a good setup, just needed some tweaking and maybe a lighter battery pack.

    I will admit, with me pushing, and the fully charged ZAP, and the gebe wide open.
    She would take lanes at will.

    I was really hoping to see you hook up a good sustainable lighting system on that thing. While the zap may not have had too much power with old batteries it would have been great for hill climbing and acceleration to take the strain off the GEBE. The purpose of having it regenerate wouldn't be to fully recharge the batteries but only maintain them for those times you needed a little bit of extra push and to run a sweet lighting system. 10 miles is also plenty for using the zap on shortcut bike trails and such and im sure you could push the electric range much further with new or better chemistry batteries. You should reconsider and be an MB god not just another one of many GEBE riders :)
