C5 lowers the max current, right? Have it apply only for PAS1 -3, and not on PAS4. Not really a big deal I often lower C5 to keep the same speed in PAS 1/2 when switching between 36V and 48V batteries. Would be nice to keep the max current in PAS 4. STill, it's 30 seconds of button pushing...

You can set the standard BBS02B firmware to run on 52V. That's different from installing the Nilssen firmware, which is what I think the Biktrix video does. I have a BBS02B and program cable, and it would be simple to do the new firmware.However, there doesn't seem to be a way to save the old...

You know about the custom firmware project on Endless Sphere? It went on for a while, but is no longer supported. My wish list for KT firmware would be 1. Input wheel diameter in mm, not presets. 2. Keep a default C5 of 10 on assist level 4 always, Then you don't lose max current. However, if...

Has anyone else had trouble with caliper screws that appear to be Torx head, but are not. Just crappy machining and neither a metric or Torx wrench can grab them.

Voltage sag in the battery will trip the controller LVC before its actual cutoff. You can get a little relief by adjusting C12. Might get you an extra mile or two. Sag is worse on smaller capacity batteries, so your results will vary,

I like the LCD3's because it's easier to view in sunlight, has bigger letters and the all important thermometer so I know the temperature inside the case. I wish KT allowed tire diameter in mm instead of the presets. I mostly go by voltage and miles, as I know my range. It's nice to see the...

Sorry you blew it up. You were trying to jump the throttle connector red-to-white to make the motor turn? In my opinion, you can't test the throttle that way, white has to be a little lower in voltage than red to make it work. Anyway, that should not have damaged anything. You didn't grab the...

No feedback on doing the learning connection for the controller?

An S866 display usually means it is a brainpower controller with self learning. I could not find an akozon listing on amazon.uk, but found plenty of S866 controllers with the same picture for about half your price. Brainpower controllers have two green wires for "intelligent identification"...

Update: TSDZ2B outer clutch started slipping at 1550 miles. Cleaned with brake fluid and re-oiled. Has been working fine for 846 miles,

Nice bike. I've built three hub motor bikes for my wife, and she's ridden over 11000 miles on then, but her favored bike for the past 2500 miles is a 26" bike with a TSDZ2B mid drive. For me, the mid drive kit is less money than spoking a q128H (AKM128) motor into a custom rim. I still have to...

That's a pretty chain ring from China. My BBS02B bike could use a blue one. Tempted,

Like many others here, I've converted many bikes to electric. Tried various kinds of motor systems too. My wife and I have ridden about 12000 miles together over the past 10 years too. We average 12 mph, although I ride faster on solo rides. I find rim brakes fine, although I do own bikes with...

I started ebiking on both 36V and 48V batteries. While there is more power on 48V, I'm happy with performance of my hubmotors with dual voltage KT 20A controllers at 36V since our average speed is under 13 mph, 20 km/hour. However, I thought our 48V midmotors TSDZ2 and BBS02B were too weak on...

I'd go with RC control. A long wired throttle cable is going to get fouled up.
