    Videos from my ebike

    Bike is a Rocky Mountain Experience with a Crystalyte X503 hub motor and controller, 91v x 20Ah of NiMH cells. Rock Shox Boxxer fork, Hope Mono 6 Ti brakes and a few other custom bits. The display is a DrainBrain from www.ebikes.ca.

    0-45mph and back to zero in 15 seconds flat. Video shot while trying to hold the camera with my left glove as well as hang on to the bars:

    0-75km/h, standing start on a 4.25% grade. There's a motorcycle behind me...

    DrainBrain much more visible (the the cam anyways) at night:

    Going fast IF you like to is great on flat lands but try some long, steep hills AND go fast with the same set up that will also go 47 mph or more on the flats both using under 1300 watts (without pedaling)that you can do for hours EFFICIENTLY not just a few minutes.

    There aren't any steep hills on my daily commute. And if I need to go up hills, 40mph on a 10% grade works for me.

    Lets see a video of a hub motor ebike go up a 10% grade hill for over 10 minutes

    I'd love to shoot that video, unfortunately there aren't any 7 mile long, 10% grade hills nearby.

    Good for your motor/controller and batteries.

    It's mighty convenient that almost no one else has climbs high enough to satisfy your requirements. Anyone with extra cash to burn could put together a bike to do that climb in well under 2 hours.

    That setup you have there is very impressive. I watched your videos in the kitchen while I was cooking dinner this evening, and I'd like to know more about how you did that stuff.

    The motor is an off the shelf Crystalyte X503, controller is a 72v x 35A Crystalyte with upgraded (IRFB4110) MOSFETs and adjustable current limiting. 76 NiMH 2D cells make a 92.1v x 20Ah pack, and the best part is anyone could build this power system with no special tools, machining or fabrication. All parts including the DrainBrain were purchased from www.ebikes.ca and mostly assembled in my living room. Installing the high performance MOSFETs requires some soldering skills, and there's an excellent tutorial here:
    http://endless-sphere.com/forums/viewtopic.php?t=764

    Most of my commuter riding averages 30-35mph, but it's nice to have extra power to maintain speed on hills, as well as going with the flow of traffic to take the shortest route.

    Simplicity and availability rules.
