    Electric drift trikes

    I see a lot of front hubs here but traditionally in cars rear wheel drive is better for drifting. Is front or rear better for drift trikes? Front is certainly easier to install

    Charging connector for BOSCH battery question?

    Thanks for the suggestions. My main problem is I don't have the components in front of me - and chargers for these bikes are $200 to $300 so I want to avoid purchasing initially if possible. For memory, I thought there were 4 pins but from a picture it looks like there are just three -...

    Charging connector for BOSCH battery question?

    Does anyone have any experience with the charging connector (from charger to battery) for the BOSCH battery (400 Wh) from a Hai Bike? I'm asking as I have a customer wanting me to set up a solar charging system for this type of ebike. It's a typical 36V lithium ion battery but the plug has...

    CAD diagram of 1968 VW 1500 Beetle

    Hello, Does anyone know where I may find a CAD diagram (or even accurate PDF or other file) of a 1968 VW beetle gearbox? Would like the diagram for making an adaptor plate and the spline for a coupler. Thanks in advance for any leads, Matt

    What's the best method to put out an ebike battery fire?

    Not too much left of fuse or BMS (see images) so hard to know exactly what faulted. My feelings now are that anything can and will fault if given enough time and frequency of use, even a top of the range battery - especially after a couple of years riding where things can get shaken around a...

    What's the best method to put out an ebike battery fire?

    Thanks for the info, all batteries are locked into a holder, either within the frame or in a double layered rack. Not sure how practical a shovel would be to get them out of this - whilst it would be good for moving it to a safer and well ventilated place. The switch was a relay type that...

    What's the best method to put out an ebike battery fire?

    Hi, am hoping for advice to ease my mind and reduce any likelihood of suffering to customers or shops who purchase Li-ion batteries (all main chemistries for ebikes) in the event of a combustion like that happened to me this morning. Particularly, what are the best methods to contain or...

    Fastest and Most Powerful Electric Bicycle Possible?

    Jeepers, harsh but fair enough. Knew there would be some pretty decent beasts out there that would put this to shame. Was hoping to see some pics or vids and find out what is available and from where. Seems that need there is a need to set things at 120V plus and do the controller yourself to...

    Fastest and Most Powerful Electric Bicycle Possible?

    Hi, I was pushing to see what I could make in terms of fastest and most powerful and also what a bicycle could "hold" in terms of electric conversions. I've put up my review on how mine came out and a few problems along the way but I'd be very interested to see what others have come up with. The...

    With or without Hall Sensors?

    Does anyone have any suggestions on getting a motor (Crystalyte High power one) with or without sensors? What are the main differences and pros and cons of each style? Typically, I find that motors I get have very few problems (nearly always ends up being the battery BMS). The only motor...

    Short tour through electric motor factory in China

    Hi all. May be of interest to some out there. Here is a short collection of photos I took on a recent trip to the motor factory to check out some kits I ordered, describes the motor production process a little...

    Suitable Suspension Forks for 500-1000W conversion kit

    I see suntour now have an "ebike" set of suspension forks. Anyone have any opinion on these ones? http://www.srsuntour-cycling.com/dstore/products/Suspension+Fork/3287/CT-SA/SF-CT-SA+26%27.html Will have to get a sample and see how adequate.

    Suitable Suspension Forks for 500-1000W conversion kit

    I'm aware that there are quite a few modifications that can be done to existing suspension forks to secure the front hub motors a lot better but I'm just looking for a production line set that needs no filing at all, is good quality, chromo (preferably) and the motor just slots straight in with...

    Suitable Suspension Forks for 500-1000W conversion kit

    Hmm, still no super suggestions. I'm quite happy to install up to about 750W on the front as long as torque bars are put on and good chromo forks. I've not had a problem with running my bike with a 750/1000W kit but I'd like to get a good supplier of forks for even the 350W direct drive motors...

    Suitable Suspension Forks for 500-1000W conversion kit

    Does anyone know of a well known brand of suspension forks (preferably easily available in Australia) that is suitable for conversion with the typical axle and wheel nut size present on most of the direct drive motors (500W - 1000W)? I do quite a few installations with the mini-motors (180-250W)...

    Solar Powered 1000W ebike and algae

    Tube cell chemistry was LMO, was stated to be 6.6Ah but it cut out at about 4.5. Can push it up to about 5Ah but the voltage drops too low on acceleration and cuts out.

    Solar Powered 1000W ebike and algae

    This was a video review I made to show a few methods of solar powering electric bikes but mainly to review the practicality of using a tube style 48V battery that can fit within the frame of the bike. This has advantages for performance and light weight but obvious disadvantages with range. The...

    How to Solar Charge an Electric Bicycle

    Yeah, this is a good way for option 3. I thought of this and pulled a charger apart to have a look at it after seeing the youtube clip of someone doing this. I have little electric ability so got someone to make a regulator for me instead of trying it but I think this would be great to use the...

    How to Solar Charge an Electric Bicycle

    If I had enough money to buy a house and then a bit spare then of course the best option would be to have a grid connected system. Second to that, I like the 36-48V panel regulated down to 42.5V and then directly hooked up to the bike battery. Even though I'll never recover the expense of it all...

    Pictures of Electric Fixies

    Yeah, that'd be pretty sweet actually. Though riding single speed is pretty fun too, no hassle, good speed and low maintenance. I've tested a few different motors and found that 350W works pretty well with the gearing with this bike, I even downgraded from 500W. You can really get the motor you...

    Pictures of Electric Fixies

    It actually has a flip flop rear wheel. Fixed and single speed. It's kind of fun fixed but not so relaxing when you're travelling quite long distances, also a touch on the dangerous side with the extra weight of the front hub motor. I've also reverted mine to single speed. Matt

    How to Solar Charge an Electric Bicycle

    There are four ways to solar charge a lithium ion battery that I know of; please comment if you know of others or better ways. Each has their advantages and disadvantages. A difficulty with solar charging lithium ion batteries for electric bicycles is that the best voltage to use for motor...

    Electric Bicycles in China

    China really is the home of the electric bicycle. I read in a review by TIME that in 2007 there were 23 million electric bicycles sold world-wide - of these 21 million were in China. Being in the electric bicycle business I had to go and check things out. Here is a short video I made of my trip...

    Pictures of Electric Fixies

    I am of the opinion that gears are just extra hassle if riding electric. Get rid of them and simplify the bicycle. Here's my design with a friend on it. The design of this electric fixie can be read here: http://www.solarbike.com.au/fixi%20story.php and a review of it here...
