    Latest Build Nearly Complete After Over a Decade

    The last bike I completed myself was over a decade ago, a 2005 Giant Rincon. It had a blowout $250 EBikeKit.com 9 Continents hub motor kit from a dealer that was going out of business and a battery that comprised of six 7Ah lead acid batteries wired up for 36 volts at 14 Ah. I couldn't keep a...

    I cheated this time

    Wanted to get back into the game on the cheap, to help me get back in shape. Looking around, technology has made big leaps since 2009, but there aren't any more $250 shipped 9C kits kicking around. I scoured eBay until I came across this bike, a Schwinn Transit Electric 700C. Has a 24 volt...

    What have I done wrong???

    I have spent all night working on this piece of shit battery, and after getting it done, it reads 4 volts at the outermost two points, where it should read 40V. On the next two innermost points (8s) I get 24V, like it is only 6S! Measured at any 9S, I get 32V, like an 8S pack.. There are no dead...

    Name that BMS!

    Can anyone help me out here? Specifically looking for the wiring diagram, any features, and the current limit. Came off of a working 36v (10S) Li-Ion pack. Thanks, Brandon

    Using Accucel-8 as a BMS?

    BMS: ~$40 for cheapest Charger: ~$50 for cheapest Total: $90 Accucel 8: $45 If I'm using an 8s pack (I am), why couldn't I just leave an accucel 8 hooked up to it all the time to balance the batteries and charge them both, instead of buying a low end BMS and charger? The Accucel chargers have...

    Venturing into the world of inexpensive LiCo batteries...

    Just bought five of these for a total of $52 shipped: http://www.legendmicro.com/store/more_info.asp?Product_ID=6019&OpenTreeBranches=0&SortBy=0 A 12 cell pack @ 5.4Ah and 14.8V tells me that there are 1.8Ah cells inside the pack, in a 4S3P configuration. 5 packs at 12 cells each gives me 60...

    Tekocell Li-Po batteries?

    While surfing eBay, I stumbled upon these: http://cgi.ebay.com/Tekocell-Li-Po-Battery-Cells-10Ah-3-9V-Litium-Ion-/360268666468?pt=LH_DefaultDomain_0&hash=item53e1af9664 I made an offer, then later retracted it. I don't have the money to throw at a battery that may not be sufficient, but maybe...

    Cheap Controller Base

    Recently I bought a floor buffer motor on eBay to toy around with driving a motor through the gears on my bike in an attempt to get more torque. The only brushed controller I have is the huge YK42-3 that I did not want to or have the room to use. I spent a few days scouring eBay to find the...

    Got tired of the pansy rear racks...

    After 200 or so miles of riding, my rear rack finally gave in a few days ago. I totally bent the rails connecting the rack to the seat post, so I ordered some more...went to put them on, and the rails that hold the rack to the bottom of the frame were bent about 45 degrees out of place and ready...

    Crystalyte 4820R Controller to EBikeKit 9C Motor?

    Would the Crystalyte 4820R Controller work with an EBikeKit 9C motor? Are there hookup diagrams avaliable? This controller would be perfect for me, but I don't want to chance blowing up my hall sensors. Thanks!

    Battery Connector Wiring on EBikeKit Controller

    Hey guys, I'm pretty sure of what to do here but wanted to get confirmation before I mess something up. I am changing the battery connector on my EBikeKit controller from a Molex connector to a Deans style connector, and as shown in the picture, I have two ~14GA wires and an ~18GA red wire. Am I...

    What do you think/what is this motor?

    I bought one of these last night just to have....it has a standard sized shaft, so it'd be alot easier to adapt to a minibike. Does anyone here know anything about it? http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=130362543208 Thanks

    Tire size on 26" EBikeKit motor?

    I recently purchased what I was told to be a 26" EBikeKit kit, and just now got it mounted. The sticker on the wheel says 26" 9 x 7. I couldn't find a tire this size at Wal Mart, so I bought an inner tube for a 26" 1 3/8" tire which I already had at home. When I tried to mount the tire, there is...

    Charging in series at 48V or parallel at 12V?

    Hello, I am building a bank of SLA batteries totaling 48V, four 7 amp batteries wired in series for my EBikeKit hub motor. I don't like the taste of paying $25+ for a 48V charger, and I already have multiple 12V smart chargers for car batteries that can charge at up to 8 amps. Would charging...

    Feasible Idea?

    I got to thinking about how to achieve higher speeds with an electric bicycle, you have to use a bigger motor, and in turn bigger batteries, to have a reasonable range. After thinking about it for a while, I came up with a solution that may work if the bicycle is mostly used on flat ground. What...

    Scored these today...

    Both for $50...two Razor Ground Force gokarts. I had to travel 70 miles and back to get them (and got lost of the way home :|) but I think it was worth it. One's batteries were ballooning and the motor cover was broken, but the other is in very good condition and the batteries look to be fine. I...

    My bike conversion

    Here is the bicycle that started it all, from my local Habitat ReStore (which I volunteer at) for a whopping $5: Note that when I got it the tires were flat, and the handlebar was very badly rusted. After an hour or so with some power tools, I got the handlebar rust free and shiny and found out...
