We’ve waited all week for this: the final photos of Paul Brodie’s completed eBee electric bicycle. By the time you read this, it will have been unveiled at the 2013 North American Handmade Bicycle Show, at the University of the Fraser Valley’s Booth — number #736, if you’re fortunate enough to make it along. Paul has been graciously updating Cycle EXIF with the steps he took in constructing the eBee piece-by-piece and finally completed it, after 485 hours of work, just in time to hit the road for Denver.

Now, I’ll let the photos do the talking:

    Trying to wrap my head around it, but I’ll say this: love those Hookworms!

    Very interesting. I want to hear tech specs and performance/ride.

    First, the build is amazing, and the skills that went into it are elite. However, while I respect the craftsmanship, it does seem needlessly complicated. I’d love to see a build that makes the application of electric propulsion nearly invisible. A road frame with a Gruber Assist seat tube motor, tweaked for long distance riding by mating it to a large battery that runs the length of a top tube (perhaps a battery that also functions as the top tube?). A simple, spring-loaded thumbie control for speed, with all wiring hidden. Such a bike would also be pretty light-weight, relatively speaking. The specs don’t need to be crazy – who needs an ebike that can go 30mph? A top speed of 15-20mph for a distance of 10 miles or so would be all a daily commuter would need. Something like that – an ebike that doesn’t scream “ebike!” – would be really, really cool.

      30 mph bikes are great for riding up steep hills at 15 or 20 mph.

    I like this bike a lot. Obviously there are a lot of electric bikes that one could build, for different uses, but for me this one’s close to perfect.

    I actually put together an ebike with the same concept — a bodger’s version of it. If I had the skills and equipment to build from scratch, this is roughly what I would make. The advantages of this design are:

    (i) mid-drive motor uses all 14 gears, so you get maximum power and efficiency over a huge speed range. This is especially useful for towing heavy loads (e.g. 4 kids) and going at high speeds.

    (ii) Unlike virtually all mid-drive systems (including mine), this one’s silent.

    I notice that there’s 2-stage speed reduction for the motor, requiring 2 chains. I guess this is due to the use of a 52V battery. At 36V would one chain suffice? (Lower power would be the drawback, of course.)

    The only think missing from the bike is the storage panniers that I have! (See attached pics.)

    Richard Johns, I love your rat!

    Good design for a handlebar Fairing. Does it house, houzze? a volt meter, ammeter, or any other electronic devices?

      I see it does house a speedometer, but maybe the device can read voltage, or amps?

    You say “Rohloff”, I say “unobtainium”.

    OK, that’s not a great chant…
