    Need Advice on Price... Enduro SL

    Local Bike Shop has a demo they are selling... a 2007 Specialized Enduro SL Expert some upgrades with a bit of use for $2200... it was originally higher (listed at $4600 back in '07) they wanted $2500, however, I fought and got the price down to $2200. I think this is still a little high for an...

    Need Help with Battery Purchase

    Looking for help with the purchase of a new battery pack. Love the one I have now 36v 10ah lifepo4, however, the cells inside are 2C and I would rather rebuild than try to make this work. Want 35mph + on flats with 9C 2807 plus good acceleration (and thus a high C battery is required)(This...

    Spring '10 Battery Build

    Pics to come in a bit but the rough idea is matching 9C's front and back... kinda like ??Methods?? dual burnout bike. Huffy frame solid as a rock after 850 miles... weighs almost 35 lbs without electronics but I'll trade weight for safety anyday ;-) The rear wheel I grabbed used and worked on...

    How to Upgrade my Build ?

    Right now I have a standard EBikeKit Front wheel on a Huffy steel frame. Over 800 happy miles on it and loving it... however... Earlier tonight I sliced the motor cable when the cable became loose and swung into the path of the wheel. (One of the zipties holding the motor wire to the side of...

    Boom... A question about -||- tolerences

    So you overload a capacitor, the dielectric breaks down and it goes boom. I understand that, however, how high above nominal do you need to take a cap before it (on average) explodes? I presume 63 volts is continuous so surge should be a bit more, however, most destructive tests I've seen take...

    Show me your Ebike silly pics

    In response to some of the more serious topics on the board I've decided to open one where you share a silly picture which would only make sense to ES members and then a short caption/ explanation. Mods feel free to move if you want, however, because every picture is about ebiking I believe...

    Ebikes + cold + large motors = ??

    Steel, one of the accepted materials of choice becomes brittle as it cools. I'm no Mech-E so I was wondering if it's more likely in winter to have dropouts crack vs deform. Simple question, however, I have no idea :-)

    20 amp infineon controller question

    I'm looking at adding regen to my controller for a multitude of reasons (mainly b/c the standard brakes could use a little help on long hills/ emergency slowing) I have the 22amp Infineon from ebikekit and as I understand it, all I need to do is run a wire across BK to ground. Then the ebrakes...

    I Busted My Rack... :-P

    Name says it all. After 350 miles of mostly pothole-free riding one of the supports to my Blackburn MTN-1 rack gave out. I guess I will try their warranty because they rate it for 30 or 40 pounds (I can't remember) and I only had 13 on there. Add to that the fact that I'm not riding off-road...

    Trek 6500

    Never too early to start thinking about the next build, right? I would probably eventually just transfer the existing motor, batter, controller, etc because they are working great A friend of mine is getting rid of his lightly used trek 6500 for around $400 with some upgrades which sounds like...

    Looking to build a 3s4p 18650 pack for ebike... need help

    I originally started this in the ebike forum, buried in another thread, however, it has to do more with batteries and as such really belongs here (plus it got lost rather quickly in the other forum) I have a 36 volt battery pack for my bike right now that I'm really happy with, however, once a...

    Help with Battery recomendations/my addiction

    It's official... I've spent way too much time the past week continuing to read about ebikes and being around you guys and gals is not helping :-P Now that my first build is a week behind me and I feel like I'm lost without an ebike (I hate walking anywhere anymore... just too slow :-P... (plus...

    E-BikeKit 36volt Front Hub on 1980 Huffy Frame

    About a week ago the much anticipated parts for my first conversion came in and I spent the afternoon installing everything. I used a 1980 Huffy Echo Valley as my host because it was cheap, in good condition, and made out of steel which I wanted. The downside to this is that the frame was...

    Building an Ebike but need help

    First off let me introduce myself... I'm a university student going to a large university in the USA. I'm in decent shape (6' 165lb) and love to ride without any assist, however, there have been a few times when I really needed that extra boost. I regularly have to climb a 10-15% incline for...
