    Nine Continent hub motor and vertical rear dropouts

    I actually haven't put the 9C motor in the front yet, owing to a bunch of delays, but if I'm going to change anything, it would be now. Do you suppose an eZee front motor would be any better in terms of maintaining handling? I was planning on putting the battery onto a rear rack to offset the...

    Fellow Torontonian here. I'll keep my eyes open for it in the northern suburbs.

    Nine Continent hub motor and vertical rear dropouts

    The rear dropouts on the Dahon Jack measure 135mm in width. They won't take a 7 speed freewheel normally, though; you'll have to stretch the clearance to about 139mm, which is generally not recommended with aluminum because of its rather sudden mode of failure under stress, but I'm guessing you...

    Its all in the name

    Personally, I doubt lycras will ever adopt electric technology, since that would be an implicit admission of the inferiority of the "pure" human-driven method. I rather suspect they'll be more like the entertainment industry, dragged into the future kicking and screaming, hoping to legislate...

    Its all in the name

    I bet that person thought you were cheating, in the same way that knights thought muskets were cheating. The difference between you and him is that there's going to be more people like you, and less people like him in the future as the technology continues to push electric bikes into the...

    Limiting Factor for Ebike explosion?

    There are two key limitations to Ebike explosions: The amount of energy carried in the battery, and the stability of the chemistry. ... Whaaaaat? >_> Seriously, though, I think ebikes will really take off when they become at least as idiotproof as a standard bike, and the cost is driven down...

    Nine Continent hub motor and vertical rear dropouts

    After yet more research, it turns out that the forks of the bike I'm looking at are, in fact, made of steel and not aluminum as I previously believed (ambiguous specs FTL!). Hence, I'm now looking at putting in a front 9C hub motor, but still using a torque arm to be safe. I've seen the blog...

    single speed electric cruiser?

    Well, for starters, you're going to want a bigger battery - a good rule of thumb is to assume a use of about 10 watt-hours per km travelled. The watt-hours of a pack (a measure of total energy capacity, and therefore range) is equal to the battery voltage (V), multiplied by the ampere hours...

    Nine Continent hub motor and vertical rear dropouts

    With a little more research, it seems that the prognosis for fitting an eZee front hub motor to the Jack are good enough to warrant further study. I do understand, though, that there is a general aversion to using a front hub motor on aluminum forks, even if it doesn't have suspension. In this...

    Nine Continent hub motor and vertical rear dropouts

    Thank you to everyone who's posted replies with suggestions. It seems, though, that in the expert opinion of the mechanics, there is no combination of axle grinding and dropout deepening that will produce a safe fit for the 9C on this particular bike. Hence, I'm currently exploring whether an...

    Nine Continent hub motor and vertical rear dropouts

    Oh, damn >_< The bike's got an aluminium frame. I was aware of aluminium not being good for bending, which may have been a problem with a front hub motor even with a torque arm, which was why I went with the rear hub motor in the first place. Is there anything I can do to avoid throwing out...

    Nine Continent hub motor and vertical rear dropouts

    <Dr. Nick> Hi, everybody! </Dr. Nick> I've been lurking these boards for a few months now, gathering information on electric bikes. The idea of a bike with an electric assist has always fascinated me, and the past few months, I've been quietly siphoning up information on these forums...
