Re: Which kit.. Stealth Geared hubs

As someone who owns both a full-suspension MTB with a mid drive and a single-speed track bike with a small geared hub motor, I also vote going with the mid drive approach. Here's why: You can get the same performance at lower total wattage with a mid drive because you have the benefit of running thr...

Re: New Generations of BB Torque Sensors (Bafang and Sempu)

I got the Bafang/EURONAU bottom bracket today. I'm not sure I'm going to be able to make it work with the Phaserunner on the throttle connection. While the input and output voltages are correct to use as a throttle, this bottom bracket has 6 wires in the cable rather than just 3 as you'd find in a t...

Re: Xiongda YTW-06 mini hub motor

I wanted to update this thread with preliminary results of running this motor with a peak amperage of 20 A. First I would absolutely not recommend this power level for anyone who's controller limits voltage instead of amps. I would only recommend this for those with a field-oriented controller like ...

Re: Xiongda YTW-06 mini hub motor

HI when uo say that at top speed you were ghost pedaling with q100 i dont understand what you mean. do you mean the bike was going so fast that you did not have enough gears to add power? is why are you not ghost pedalling with de ytw since it goes faster than the q100? tx It's a long story, but th...

I really wish it was possible to buy direct from Bafang. They have 4 items on their site that I would buy today if they had direct sales. I haven't found the Bafang BB with ISIS shaft standard on AliExpress. The EURONAU BB is listed 3 times, but it's the same square-taper JIS BB. I personally think ...

It does, but not sure if its supported by the CA as pre-controller ?
Probably it has its own "intelligence" inside ?
I don’t use a CycleAnalyst, just the Phaserunner by itself

Re: New Generations of BB Torque Sensors (Bafang and Sempu)

That Bafang BB crank looks really promising with those input/output voltages. Since I have a Phaserunner that has programmable throttle levels I think I’m going to pick that up for my bike.

I can't wait to see the shakedown test ride video. Watching the build progress and trials in development has been really awesome.

Re: Xiongda YTW-06 mini hub motor

Is the q100h much more powerful? I m considering adding a front geared motor to my cargo bike. It would complete my rear DD as there are lots of load I don't know if I'd say "much" more powerful, but it seems so far like the Q100 can take more. The Q100h was easily taking 20A from a 13s pack (1,092...

Re: Middrive or HUB on Single Speed Bike

I just finished building a single speed ebike. I have a build thread documenting it. One thing you’ll need to keep in mind is that the single speed frame has a rear axle length (the distance between the dropouts) of 120mm - not the 135mm like bikes with multiple rear cogs have. So when picking a mot...

Re: Xiongda YTW-06 mini hub motor

I forgot to mention, the Phaserunner doesn’t have any input for motor temperature or speed.

Also, the PhaseRunner is designed for up to 72V so both your 20s and 21s batteries are going to be too much for it

Re: Xiongda YTW-06 mini hub motor

I don’t think any geared version of this motor will sustain 30+ mph. And this is definitely not a motor to use if you want torque or to carry cargo like a kid and another bike. The 17.5:1 geared motor, with a fully charged 48V pack (54.6V), tops out at about 28 mph. That’s a guess though because I d...

Re: Swapping Freewheel Side Cover for a Freehub Cover

I believe that the Q100 series have faceplates that can be swapped. For example, you could get a Q100H and a Q100C then swap the clutch and ring gear (not sure if the ring gear can come off or not) between the faces and use the freehub on the Q100H. I haven't done this myself, so I honestly don't kn...

Re: Advice needed - charger connector burned out

Yeah the charger was plugged in to the wall outlet.

Re: Single-speed track stealth ultralight

How many miles so far? Is the motor still loud? Still working fine? I'm probably just a bit over 250 miles now. I'm not really keeping close track TBH. The motor has quieted down a bit both during operation and when rolling. It's still a slight touch louder than a Q100 at certain RPMs and power lev...

Re: Looking for rear Hub motor for hitting 40mph on flats

My advice would be to not worry about who's d*ck is bigger, and let the gasser go. Take the money you save trying to get another 10mph out of your bike and treat yourself to something that will make you happy for more than the 10 seconds you get passing the moped that one time. You can feel good abo...
