    Electric recumbent bike project finished!!!!!!!!!!!!!

    The setup is an ecospeed 750W... with two 36V 15 AH batteries making for a total of 36V, 30 AH.

    So far I've taken it to ~39 mph on flat ground (could go a bit faster than that!) - maybe even a tiny decimal of a degree uphill. That is without pedalling, and without the fairing! I have yet to install the tailsok as well! I just got done putting on the fairing and installing. The batteries, motor controller, on/off unit (bought from Brent - nice unit!) have all been attached via hose clamps.

    Also - Boblbee (sp?) hardshell backpack, Craft RX6 Evolution helmet, Icon Pursuit red perforated jacket

    The recumbent bike is a Sun EZ1-SX.

    Tomorrow I'm getting the Big Apple 2" wide 20" tires installed.

    It does great with traffic - speed and all! I love it!

    -----------------------------

    I don't know the range yet - but estimates are anywhere from about 20 or 25 miles using full power and no pedalling - and perhaps 60-80 or so with light to very electric use. Once I get a bit more mullah I'll be able to get a Brain Drain... or maybe it's called a Drain Brain... and then I'd be able to figure out the range!

    The batteries weigh about 22 pounds total I think. The motor setup is I believe 12 pounds.

    The bike according to the manufacturer without anything weighs I think ~ 40 lbs. So about 75 lbs would be my guess! The Sun EZ1-SX is an entry level steel recumbent - so it's already a kinda heavy bike to start with. But I feel safer with steel than with something lighter... plus I suppose it's able to flex better and absorb some of the bad road conditions here.

    The motor kit is from www.ecospeed.net ... I got it through and independent resupplier - Brian Howell who runs www.electric-bikes.com.... the site has all kinds of information about all kinds of smaller vehicles.

    A good friend of mine & I have been discussing all the various ways to electrify a 'bent.
    From those discussions, might I/we suggest putting the batteries in a B.O.B. trailer?!
    All those batteries hanging from the frame make it seem more like a "Difcult1", than an EZ1!
    Our next project is to install a StokeMonkey motor on my Greenspeed tandem.

    You've got a cool rig there though. Always nice to see someone doing it, rather than discussing it!

    Does your head not get wet riding a bike with a motorcycle helmet? A face bike helmet is allready uncomfortably hot.

    Thanks!

    It would definitely seem so - but the only time it gets hot is at a stop or when I'm locking the bike up... it has very good ventilation!

    Hmmmmmmmm what's a BOB trailer?

    Hehe - it's actually a good handler! The battery positioning gives it a nice center of gravity .
