    Cafe Racer Bicycle

    My latest project will be an electric bicycle. My intent is to model it after a Cafe Racer. Something like this:



    I thought about adding a gas tank to a bike frame but I found this:



    Waiting on eBay parts. More to follow.

    Thats a pretty cool frame. Is that an actual fuel tank on it?? The seat on that cafe racer looks pretty cool, but im thinking may be a fast ride on the Hemorrhoid express :P

    Yes that's a functional fuel tank. Frame is $120 bucks out of China. I can't source materials for a frame for that price. The seat also has to accommodate the rare possibility of pedaling.
    Another beautiful example:

    Beautiful frame for sure.
    Is the frame SS, Chrome Moly or anodized aluminum?

    Those Triple engines Honda used were killer.

    Use to know a guy from back in my drag racing days that ran a 750 Triple.
    That thing was down right mean & nasty.

    I truly miss my bike days, but these days it seems like every Tom, Harry, Dick & Jane is trying to use bikes as target practice with their vehicles.

    OCD:

    The deer are after bikers too.

    I was driving into work last fall, late October-ish, and I was following a biker. We were doing about 60 mph when a deer came running up out of the ditch and jumped over the biker. I was probably 200 yards behind the bike and from that point it looked like the deer only cleared the biker's head by about 6". The deer may have actually been much farther away than that, but it looked close from my angle. The biker pulled over in the next town so I pulled in behind to ask how close the deer actually was. I asked her, "Out of idle curiosity, just how close was that damned deer anyway?" She jumped about a foot in the air yelling "What deer, where?" She'd never even seen it. Which is understandable, because when I saw the deer it had just come out of the tall grass in the ditch. It looked like the deer was running flat out as it came out of the ditch and crossed the road.

    That's as close as I ever want to get to a deer/bike accident.

    Just getting an idea of how it might look:



    I need ideas for the seat. Not sure how to style the seat front where it meets the gas tank. I figure I could use the rear brake mounts to hold the back of the seat if needed.
    Also thinking about cutting out the filler hole and making a hinged door there. Then I could use the tank for storage. I don't want to weaken the cross bar though...thoughts?
    I still don't have a drive wheel...darn eBay sellers.

    Hmmm, i think you might winde up cutting a u shaped slot in the front of the seat to slip around the gas tank. That way it can sit lower and keep up with the aesthetics.
    How about a pic with you slumped over in riding position on it to get a better idea of where your ass sits. Cardboard templates are your friend. Lol

    All good points. I think it will be important to slide forward on the seat to sit upright when cruising and slide back on the seat when in the "race position." I will get a pic so you can see the frame size with a rider.
    The frame is TIG welded aluminum and then flap disc sanded. It is very well made.

    I just test rode this!



    OK. Ignore the duct tape and lose wires, this is just a test...

    Damn thing it fast. Maybe too fast. I need to add a emergency shut off. I would like to be able to interrupt the 48 volt power from the battery in an emergency. What kind of emergency stop switch can I use?
