    How to protect triangle frame battery from theft

    Hi I would like you advise on how to protect the triangle frame battery pack of my e-bike. I park the bike at the university and I am usually no more than a few hundred feet away from the bike. The battery pack sits inside the frame, in a waterproof case. The case is attached to the frame via...

    Is this 1500W VooDoo HooDoo MTB e-bike worth £1533?

    Lots of questions but I doubt the seller with bother answering them. I've contacted Grin Technologies and they'll help me choose a kit. Then I'll either find someone knowledgeable to install it for me or do it myself.

    Please recommend a high-powered e-bike

    @teslanv Sorry for not replying sooner. I just realised that the thread had been unlocked and order had been restored. 1. Great website, very informative and aesthetically pleasing. Succint too; no walls of text to overload you with info, sometimes irrelevant to the topic at hand, and confuse...

    Please recommend a high-powered e-bike

    Thanks for the support. My initial impression of the forum was a bit disappointing (based on the responses I received...). Now the DIY route seems more and more attractive. Actually, I did ask people on the pedelecs forum if they could build an e-bike for me. There was this one guy, very...

    This bike was even featured on a morning show in the UK https://www.youtube.com/watch?v=mPdXahSoUo4. On teslanv's website https://kinayems.com/Support/HowFastHowFar, at the subsection titled The Calculus of How Speed affects Range it says that a bike with: a) curb weight of 330 lb b) traveling...

    Suggest 52v/30Ah battery for Voodoo Hoodoo e-bike

    I have the impression that this kit was put together by the seller with parts sourced from different companies. He sells these kits but he installs them as well. The batteries he sells use cells sourced from Japan and then assembled in China.

    Damn, I am disappointed to read that. I was fired up and ready to buy that bike after watching this review on TV (https://www.youtube.com/watch?v=mPdXahSoUo4) Was the presenter bribed?!? Or maybe that's not even the bike I would have paid for (even though the seller claims it is).

    60v/30Ah battery from Alibaba for $99?!?

    Great post. Very informative. So if a cell is rated at 4.0V, then a 52V/21Ah battery should contain 52/4=13 cells? Or are there multiple sets of 13-cells pack that are interconnected in some way?

    60v/30Ah battery from Alibaba for $99?!?

    Look around this forum? There are thousands of threads; where should I look first? There should be a sticky with "reasonable prices" for "medium quality" kits/batteries/etc so that people know what prices to expect to pay.

    Suggest 52v/30Ah battery for Voodoo Hoodoo e-bike

    According to the Ebay listing at http://www.ebay.co.uk/itm/1500W-Electric-Bike-Kit-inc-52V-21ah-Battery-121-Build-Assist/222440803370#rpdCntId, Max. Speed: 600RPM. Is that it? Maybe it's 600RPM / 48V = 12.5KV?

    Suggest 52v/30Ah battery for Voodoo Hoodoo e-bike

    I do want to buy that bike but I am concerned that I might be overpaying, especially since I've found other "1500w bikes" at half the price (~800 instead of ~1600). Actually, I attempted to buy the bike via Ebay but the purchase was cancelled by the seller. He did ask me first and I accepted...

    How do I select the appropriate values for the first three parameters in the simulator? The ebay listing of the kit I am interested does not provide this information. Or are you able to deduce them from the specs? Is standard 4T wind hubmotor = CLyte 4xx? There is no 52v/21Ah battery in the...

    Suggest 52v/30Ah battery for Voodoo Hoodoo e-bike

    1. Watch the video again. He mentions that the motor is 1.5KW and then says "It's capable of pushing this bike, unassisted, at up to 75kph". He never says "50 to up to 75kph". 2. I said 50mph in my original post because that's what the seller is claiming on his website. In any case, 75kph is...

    Suggest 52v/30Ah battery for Voodoo Hoodoo e-bike

    The ebike seller is selling a 52v/20Ah battery with top quality Panasonic cells (and the charger) for £500. Is that a reasonable price for a battery of this size? He said the cells are made in Japan and the battery is assembled in China, then imported to the UK.

    I am amazed to hear that! This bike was featured on this British morning show and the resident "gadget guy" specifically mentioned a top speed of 50mph and an assisted range of 150kilometres. https://www.youtube.com/watch?v=mPdXahSoUo4
