Greetings, I'm really enjoying this firmware with my VLCD6 display. Particularly great is sensitivity to sub-revolution pedal strokes, at least when coasting or accelerating from stopped. One challenge I find is when coming to a stop, the torque sensitivity is still higher than I like even when...

I recently purchased a battery from dhgate that was advertised as 48v and 15 amp hour bottle battery (full specs below). Upon delivery I was quite surprised to find that it was half the length of another bottle battery I have on hand, rated 48v and 14.5 amp hours. I know little about batteries...

I tried the bafang lock ring, but it was too small. Are there other options out there? A double setup like the bafang seems ideal, as the single backs out even after threadlocker and heavy torque on the nut.

Would anyone have have advice on how to tune the soft start parameters? It is far too soft for navigating in traffic. I want rapid acceleration. I'm an avid cyclist and prefer to modulate torque with my feet rather than software, and am willing to risk damaging the nylon gear.

Okay, I tried tightening the 5 bolts closest to the drive-side crank that hold the spider to the main drive gear. I gave them 5nm, didn't want to give more for fear of stripping. The spider was still loose. I then removed the main drive gear and noticed that I lack the brass spacers behind the...

I'd be curious about your input on lateral play of the chain ring spider on the axel: https://www.youtube.com/watch?v=I7ueCrxFKOU You can feel the chainline changing under torque. Is this something worth repairing?

I'm interested in marcoq's firmware for VLCD6. I've installed both JRE and SDCC compiler, but am unable to flash the firmware within the configurator (I am in an OSX environment). I can install his firmware with stm8flash, however the stock eeprom settings are for the 36v, and I have a 48v...

Tried the following: echo "00 00 ff 20 df 00 ff 00 ff 00 ff 00 ff 00 ff" | xxd -r -p > option_bytes_pwm_n_channels_enabled.bin stm8flash -c stlinkv2 -p stm8s105?6 -s opt -w option_bytes_pwm_n_channels_enabled.bin stm8flash -c stlinkv2 -p stm8s105?6 -w 48vprogrammemory.hex stm8flash -c stlinkv2...

The display is larger than I want on my bike for the open source solution.

eco-ebike.com now offers some customized firmware for the TSDZ2 that I'd like to try: https://www.eco-ebike.com/blogs/eco-cycles-instructionals/tsdz2programmingfromscratch They offer instructions on how to flash with the st-link software, but I don't have a windows machine. My plan was to try...

I've noticed a few mm of play in the spider of my Tongsheng motor: https://youtu.be/I7ueCrxFKOU I've removed the five bolts, applied blue loctite, and reassembled with torque at 5nm, but the play persists. Is this normal? I noticed a large bearing inboard of the spider that protrudes from the...

I'm thinking about getting a shimano di2 alfine hub for my commuter, which is set up with a TSDZ2 motor and 48v bottle battery. Has anyone tried to power di2 systems with an ebike battery and can point me to some resources on how to set it up?

If you'd like the VLCD6 to display mph, simply take the circumference values listed in the manual and multiply them by 0.62. If you want to set the speed limit to 45km/h hold down the power and + button for 10 seconds.

Interesting, thanks! I've had luck adjusting the speed limit and circumference on the VLCD6, but not the power. I fear that I'm not getting the most out of my motor. Does anyone have any tips for adjusting power on that display?

Would you be willing to elaborate on the performance characteristics of VLCD-5 vs. VLCD-6? I chose the latter because I was looking for a low key display, but am wondering what performance downsides it might exhibit.
