    Apples and oranges: Converting to Lithium

    Hello everyone, I haven't posted in this forum for a while. But I have a damn good reason. I've been very busy with my studies getting a BS in electrical engineering, and after 4 years I discovered that someone converted a miata to electric (Don't laugh!) and donated it to the university.I am...

    LiPo-phobia Immersion Therapy

    I used to be very afraid of LiPos, but I'm working in a robotics lab over the summer, and am surrounded by LiPos for their flying machines. I have four of them charging 2 feet from my face as I type. I suppose this will make me more confident to use them in the future. :twisted:

    What can you tell me about Tidal Force motors

    Apparently they are American made (For military use originally), and the company stopped making them. Also, they had an odd system of butting an 8AH 36V battery in one of the wheels. That's all I know so far. The reason I ask is because someone in my county is selling a non-working bike with one...

    Automatic hub

    I know internal gear hubs are very easy to use anyway, but as a thought experiment, would it be plausible to use one of the automatic hubs (Like the SRAM Automatix or the Shimano Auto 3) as a final stage in transmission? I think running a small 24 volt motor through one of these should not cause...

    Making a cheap 24V brushed controller run on 12v

    I have a couple of cheapie brushed controllers that I want to hack so I can run them on 12V (My reasons are my own :wink: ), and I would like some advice. I suppose I just have to defeat the low-voltage cut-off circuit (LVC). If I post a picture of my controller's circuit board, could you folks...

    Installing Turn Signals and a Brake Light.

    I am planning on installing the above-mentioned features (along with a head and tail light) on my 36 volt bike, since it is often used as if it were a moped in a 20mph zone of my hometown, and I thought it would be a good idea for safety and convenience. I am going to use Lyen's handy DC-DC...

    Blueb0ttle2's Lithium Noob Project Thread

    After almost a year of mulling over and reading about the subject, I am prepared to get a lithium pack. And I am open to suggestions. But first, some back story... I got a Tres Terra Europa electric bike, which runs on 36 volts and (I presume from the brushed Heinzmann motor's specs) will take...

    Headway Headquarters, Any Good?

    Anyone have good experience with these folks? They are in the USA, assembling packs from headways. Their prices are comparable to pings, and IMO these packs would be easier to repair if a cell fails, since they are screw tops. What do ya think?

    Plotting on making a bicycle-powered dynamo

    I know, it sounds a bit Rube Goldberg (Or Heath Robinson) like, but since I can't afford solar panels, have an extra brushed motor lying around, and a junk bicycle, I thought, what the heck. I sense that energy shortages may be coming soon and I want to charge batteries to run other devices in...

    MORGAN 3 Wheeler is back!!!1!

    All right! If only I had the dough for this! Might make an interesting conversion. Apparently it will be available without the tacky bomber pilot paint :wink: But that may be part of the charm.

    Using a Sturmey Archer Fixed Gear Hub

    I've mentioned in several articles my desire to change gear ratios without giving up my Ezip's convenient motor mounting arrangement. Many have suggested Jackshafts, but I think I may have hit on a simpler solution. Sheldon Brown, perhaps in a fit if unorthodoxy, made a LH drive fixed gear...

    Where to get some dual-freewheel thingamies

    I'm looking for one of these in the USA. It's not too pricey to get it from these guys in France, but I would really like to reduce my carbon footprint (and save a bundle on shippin') :mrgreen: .

    Strumey Archer 2-speed kickback hub

    I stumbled across SA 2-speed hubs on amazon, and am interested in them due to their simplicity (Less things to go wrong). They have 100% and 138% drive, which would be adequate for my needs on an ebike (Torque n' speed!) I was thinking of making a chain-drive project with this, and kicking back...

    Reducing RPM by reducing voltage

    I know what you guys are thinking, why reduce voltage? Well, in my musing about what to do with the parts I have lying around, I was thinking that my MY1016 motor could be hooked to my Strumey-Archer 3-speed hub with one of these wonderful things. The biggest #25 sprocket that I could find that...

    Ezip battery connection problems

    First of, thousands of folks own ezips and I bet the forum would benefit from having it's own ezip area so that newcomers with ezips would have a place to look, and so we don't clutter up areas that would otherwise cater to more sophisticated or extreme ebikes. Second, I am beginning to see...

    Average lifespan of lead batteries

    Before you folks make the usual jabs at lead, how long would you say lead batteries are supposed to last? And what criteria would you use before going out and replacing them? One of the battery packs on my ezip is beginning to behave sluggish after 6 months of (almost) daily use, and range is...

    Changin' GEARS!

    I look with envy at the cyclone set-up, and wish I could switch gears on my ezip. I'm locked in one ratio which is only adequate. But, I want maximum efficiency and speed! I'm thinking about all sorts of Rube Goldberg (Or Heath Robinson, depending where you're from :P ) set-ups for changing the...

    Belt Drive, Some Thoughts

    The first time I built an electric bike, I used chain drive and my ratio was inadequate... http://evalbum.com/3389 I really liked the way I mounted my motor though, and I've been thinking about more ways to drive the back wheel. Then I saw this gasoline motor kit.. And it turns out that they...

    Aluminum Vertical Dropouts

    I am helping a friend build an ebike, and his bike has full suspension and disc brakes! Whoa, I thought to myself, a dream come true! But then I noticed that the frame was aluminum, and had VERTICAL dropouts. :cry: Can I use a hub motor on his bike, as long as it's got a torque arm? I am...

    converting this???

    I am just musing, since I ain't got the dough, but would it be possible to convert this thing to electric? http://www.hammacher.com/Product/11078?promo=search It is a three-wheeled "Scooter coupe", but I think with a bit of tinkering it could be made into a 3-wheeled car. Since it has two front...

    Pimp My Ezip

    When my Ezip failed me I decided that it was time to improve it. It was slow to accelerate, and the 10 AH SLA Batts suck. But I had no extra cash. So what did I do? Connect BOTH sides of the Battery Rack in parallel of course! :idea: The Ezip has space for two battery-packs, and you are...

    My Ezip crapped out today

    Somehow I don't think Ezips were designed for commuting, after 4 months of almost daily use, a fresh battery and a pleasant morning brought me a dead ezip. I can't run any electrical tests on it since I'm at work now, but the wiring seems (physically) intact. First it motor-boated, then all the...

    A Power Sidecar?

    I've been looking around and see a lot of power trailers, but has anyone tried a sidecar? As far as I can tell, It would have the advantages of stability, not forgetting it's there,and not taking up so much space. Cons, I gather, would be finding a way to secure the motor. I'm partial to using a...

    Flying Pigeon

    WHAT! Why is someone reviewing that hunk of junk here?! :shock: Well, I grabbed a new one at a decent price (1/6 the price of a Pashley, 1/2 the price of an old Raleigh DL-1 on ebay) and thought it could be fun as an extra commuter bike. But, can it be converted to a stylish electric cruiser...

    Fun with a Heinzmann

    I installed a 400 watt Heinzmann motor, and my battery is charging. I'm anxiously awaiting the test, since I've never used a hub motor before. Pity I'm using 24 volts worth of lead :( The Heinzmann is supposed to be torquey, right?
