Re: My Bafang Ultra Mountain Bike! Frey AM1000

I'm considering one of these bikes. How does one customize a bike? I see a bunch on Alibaba, but I don't see any way to customize. Of the bikes on Alibaba, they seem to range from 2200 - $3800 before shipping, but I don't see much difference in the specs for many of them. What am I missing? Just co...

Nice! Where did you get the Tektro HD-E725 brake set?
Funnily enough I recently ordered 120 LiitoKala 26650's myself, along with a "smart" BMS. They should arrive just in time for the holidays for me to be too busy to do much with 'em. :D

Re: Another Stealth bomber (clone) build

Do you have any pics of the guts inside your older Sabvoton, compared to the newer one you're looking at? I'm wondering if it's a difference between the ones you get from qsmotor, and third-party sellers that somehow have custom ones that they pair with their own TFT display, which is what shortcir...

Re: Another Stealth bomber (clone) build

As you know...your Sabvoton is toast. I took it apart, found a blown transistor in the LCD and a bunch of blown mosfets. The filter capacitors in these controllers are horrifically inadequate. Not only are they cheap, but there is about 3-4X less capacitance than what is needed for a 24 fet control...

Re: Another Stealth bomber (clone) build

Yup, based on my experience in the last few weeks, many vendors often (1) don't respond to basic questions about their own products, or (2) at a certain point they stop responding, or (3) can't answer straightforward questions about their own products.. Which is SO damn frustrating. *@!$@# This vend...

Re: Another Stealth bomber (clone) build

@shortcircuit911 Did you get your TFT and controller as a kit somewhere? Seems one can't buy the TFT separately... I even tried asking several vendors, and the only one that would respond, said: ...

Re: Are my expectations as a customer just too high?

IMO, sometimes things happen, but there is no excuse for a consistent lack of communication and over-promising that clearly violates a customers expectations. The first week of October was also the "Golden Week" in China. Because of that, a chinese company I ordered from online, notified me in advan...

A few days ago I contacted Qulbix because I noticed they have a frame sale going on and asked if they offered a frame kit for the Q140MD and they said they didn't - you can only get it in a complete bike. I really like this design - a bike with a center mounted DD motor. The HPC Typhoon Pro and Vect...

Re: How Leili stole and lied to me (most known frame company)

Honestly it sounds to me that if they were really out to "steal" your IP, there would be much easier and insidious ways to get it done. For one the manager wouldn't have admitted taking your work to their exhibit. It sounds to me more like a low to mid-level employee doing his/her own thing and muc...

Sources for battery packs that use ultrasonic wire bonding?

Hi,

Is anyone aware of any other vendors that produce battery packs that utilize ultrasonic wire bonding? Luna is the only one I've come across that does it.
