Re: Ebikeling 500w Geared Hub Kit

Which wires need crossed to "hot wire"? Going for stealth on my bike and would like to rid the controller. I am not sure about the type of display unit you have, but the procedure below worked on my 880 and 810 LED units, with a 5-pin connector. The LED display mounts are notorious for br...

Re: Ebikeling 500w Geared Hub Kit

I've used that kit (36v,500w 700c rear wheel) and 24mph with pedaling is no problem on high power. The controller has 2 blue power wires; open = no restriction: shorted = power diminishes to nothing at 20mph. It's really a good feature since the range in low power is fantastic at 19 mph since human ...

Re: Batteries - a better approach?

Just to clarify,... Are you actually using OEM Makita 10.5 Ah packs ? I cannot find any reference to them at tool stores. Milwalkee have 9Ah , and Bocsh have a new 12Ah 18v pack, but the costs is ludicrous..$250 ? If you can find them. Sorry for the long delay in answering. I've spent the the summe...

Re: Batteries - a better approach?

Yes, each has a internal BMS. The BMS in true Makita's balances the cells, but the largest capacity available only 10 cells and 6ah. The BMS in the batteries I have built don't balance the individual cells. They use 15 genuine LG MJ1 cells (3.5ah-10a continuous). I've added a 6 pin header to allow m...

Batteries - a better approach?

I find quality ebikes being dumped for a few dollars on Craigslist. Reason? Battery failure and owner's not willing spend $700 for another proprietary battery that will likely fail much sooner than advertised. I bought a 2014 Izip E3 Dash last weekend. Nice bike, bad battery, very cheap price. Rathe...

Re: connecting five-wire ebike LED display to apparently uncompaible controller

I doubt the 810 display will work or if any display is necessary. That controller is sold by 7 different eBay vendors. One would think one of them would label the wires with clear descriptions. But alas, they are all the same and the English translation..... unusual. With an ohm meter check to see w...

Re: Tandem electrique

Details and pictures would help. I assume the girlfriends bike is a rear drive bionix conversion (135mm) drop space and you tandem' space is 140 or 160mm. If so, not easy to do. Also, rear drive tandems are really tricky if you ever need to ride it solo. Slip and spin. Consider a front gearless kit ...

Re: Stromer Mountain 33 Motor & LCD -- Repair / Hacking

I have 2, Stromer 36v500w Power 48 wheels that look very similar, inside and out, to amberwolf's Mountain 33 motors. I finally have a use for them, so I opened one hoping to remove the controller and connect an external controller directly to the motor's phase wires and hall sensors. I had hope to r...

Help with bike identification

I picked bought this bike last weekend. I thought it was a Ezee Forza RWD from the fuzzy ad pictures. It's a copy of the Forza! Same geometry, Al frame/steel fork, battery slot, rack, and rollerbrake. No decals anywhere except "Mode" on the fork. I can find anything similar on the web and ...

Re: Smallest battery suggestions for 6 mile ride and Bafang BBSHD

I like tool batteries for all builds. For a short trip bike, they are really well suited. My choice is Makita or Makita clones because of cost, compact size and easy to build mountings. The 15 cell clones 5s3p with quality cells is my first choice because they can easily handle 30 amps. Genuine Maki...

Re: Problems with latest Ebikeling controllers

Amberwolf, thank you for responding. After careful comparision, both boards are the same. The outside label is 2016xxx for the ones that work without the 5 wire LED display and 2017xxx for ones that must have the the display. The MCUs are both Infineon F-SC836 2FRI-AB and includes 8K of memory. The ...

Problems with latest Ebikeling controllers

I've done several builds with Ebikeling kits and tool batteries (Makita). The Ebikeling controllers come with a 5 wire connection to a LED Display (Batt+,V+, Gnd, Tx, Rx). You must choose either 36 or 48v model LED display. Until my last delivery, a simple on/off switch between Batt+ and V+ could be...

This is a great thread with good information; well documented. Thanks GCinDC and to all who contributed. I ran across two TDCM Ulta, power 48, 36v, 500w complete rear wheels and bought them for a few dollars! I pretty sure they came off Stomer ST1 ebikes. Since Stomer dealer replaces parts rather th...

Re: Using cordless drill batterys

IMG_2025r.jpg IMG_2026r.jpg Tool batteries are great for ebike power. My experience is with Genuine Makita 18V and much cheaper Chinese clones sold "for Makita". But, I think you can expect the similar result from DeWalt's and other quality tool makers. I've converted 3 tandem using 36V 8...
