    ebikes.ca Ezee hub motor kit with LiFePO4 4.5 years on.

    Thanks Dogman. That made a lot of sense. I teach Maths and a bit of Physics, so probably should have figured that out by myself. Can also get access to school power supplies as well I'm sure.

    ebikes.ca Ezee hub motor kit with LiFePO4 4.5 years on.

    As I understand it the BMS is a balancing type, but I suppose that is designed more to keep a currently balanced pack in order than fix a badly balanced pack correct? I am currently flat out with my position at the new school, jobs around the new house, and other bits and pieces. If I get some...

    ebikes.ca Ezee hub motor kit with LiFePO4 4.5 years on.

    Well they still get me the ~10km return, but the voltage seems a bit more saggy. I pedal a bit harder to get up the hills. I'll hook up the CA when it arrives and report here.

    ebikes.ca Ezee hub motor kit with LiFePO4 4.5 years on.

    This is my first post in about 4 years. I bought a ebikes.ca Ezee kit around about August 2010 and installed it into a Kona smoke (all chromoly). Rode it regularly for a year and a half then got a job in South Otago NZ, (wet, windy and cold) and lived literally next door to the school I taught...

    Recommended electric bicycle kit for educational workshops?

    How about brushed DC motors, BMX pegs as a friction drive roller, a simple controller/switch and a 12v deepcycle battery. Doesn't get simpler than that.

    hightekbikes.com motor kit review. Electric bike kit.

    Back EMF is basically Newton's third law in the context of electromagnetism. Magnets spinning near a conductor induce a current in that conductor. This current has to oppose the movement that created it, otherwise the magnets would speed up and up and you'd soon be going faster than an F-15...

    LiFePo4 Batteries: Care and Feeding For Beginners

    Yes buying a 300+ USD battery and then not spending another $50 to properly mount and protect it is false economics. Factor in the case to your battery price when considering purchase. http://www.carradice.co.uk/index.php?page_id=product&under=range&product_id=31 I've ordered one of these...

    Hyena's e-bike builds (now with HD video)

    Hey you should put the LiPo in one of these. I've just ordered one from England for the kit you're sending me. If it will fit LiFePO4 then it will fit LiPo for sure. http://www.carradice.co.uk/index.php?page_id=product&under=range&product_id=31 That's a big ass seatpack. It was actually...

    Cytronex system

    It's not aimed at the American market. If you were a Brit with the power limitations and speed limitations that they have, then it would seem a fair bit more inviting. The bike itself is supposed to be like a roadbike with a little extra. I'd love one to supplement a stable of bikes.

    The Good, the Bad, and the Ugly with my new Bionx PL350

    There's custom electronics in both the battery, motor and handlebar console. They all talk to each other making simple replacement of a part a non-starter. It is possible however to recell the BIONX battery, I believe that there's a thread somewhere on this board about how to do that. It would...

    LiPo battery care and basic information

    I have a question. If one got a prebuilt LiPo pack from a reputable supplier, what would be the actual chances of this over voltage->boom occuring? Asking because ebikes.ca now has LiPoly options for their Ezee kit. I'd assume that that pack has a BMS to ensure proper charging, so I shouldn't...

    First bike- Finally!

    It really doesn't say. But it's got to be at the wheels. There's no other rational way to interpret a limit on power. How much goes into my lights and ohmic heating is really irrelevant. Anyway after looking at the feedback I've gotten here, I think I'm gonna take the route taken by most put...

    First bike- Finally!

    That's funny. I've got the RST 2010 catalog right here in My Documents, and for the 790c it says quite clearly that the steerer Stanchion and castings are steel and the crown is Al. Maybe the specs changed? Anyway I'll be sure to do the magnet test. Can't argue with a magnet. Or I may replace...

    First bike- Finally!

    If it's over 300watts then it's 'possibly a motor vehicle' the law is simple but vague. They intentionally left between 300 and 600 watts as a grey area and anything over 600 is a moped pure and simple. One thing about this law is that it makes it really simple to import EU and UK spec bicycles...

    First bike- Finally!

    Absolutely I'd love to get a x5. I'd also love not to have my bike impounded. :wink: I'm reconsidering the Elation. I'm not married to any particular idea at this stage, except getting the best for my money, not getting in trouble with the law and keeping out of hospital.

    First bike- Finally!

    Oops. I'd checked a bike that was in the next range, and I posted a picture of this one. Brain fart there. Anyway here was the bike I checked. In my defence I'll say that they are practically the same in all other respects. http://www.avantibikes.com/adventure/discovery8-c.aspx?bid=254 It's...

    First bike- Finally!

    I guess I need to clarify one thing. The 300w limit is current NZ law. There's also a provision that motor power between 300W and 600W 'may not' be a motor vehicle according to the discretion of the transit authority. I want some kind of future proofing for higher powers later. The Ezee kit is...

    First bike- Finally!

    One thing about hub motors is that at the high end of the range- where it really counts- they really do only put out 300watts or less. It's for hill climbing where the extra wattage shows up in the midrange. I could always derestrict it for hill climbing if it's an issue.

    First bike- Finally!

    I've certainly thought about that. But I want to keep it legal at least at first. If I was in an accident and they find my bike is illegal then it's big trouble. I want to be a schoolteacher as well and even minor legal problems can really through a wrench into your career. But yeah after a...

    First bike- Finally!

    If I need more power I'll get a motorscooter or similar, or just take the car. I also want something legal as a starting point. When you learn to drive your instructor doesn't teach you how to run red lights. If 300watts isn't enough then I guess I can always turn off the current limit on the...

    First bike- Finally!

    I have certainly considered Alan's Elation kit. I think it's a very good kit. I've also considered a 9c with Nicads and just buying a ready made bike available in NZ, the Wisper 905. First did I mention safety? I could fool the cops but "mother Nature can not be fooled." Feynman said that of...
