Congrats you've completed your build! Looks very classic without too much of an ebike. I think the battery need to be wrapped with chrome to look like thermos water bottle for stealth looks. Looks like you've worn out the friction tape quite a bit for just 15 miles. Put that floor grip tape...

For my Qiroll Pro: - If my wheel moving; when i press and hold the mode button the regen brake kick in slowing down the bike. - When at stop wheel not moving; holding further the mode button for few more seconds (probably longer than braking mode) puts it to sleep....sometimes its a hit or miss...

No problem with my Qiroll Pro even after a year worth of abuse commuting to work. I only need to lube & grease the internal rollers/bearing as it made squeeky sounds few months ago on Oct 2023 (after a year of usage). I must say its a great all weather minimalist ebike kit after the last mods...

Still here riding my ebikes. Nice bike to mods, how's the progress?

If you trim the tape rough surface at right texture it will last or equal to the same friction of tire would roll on the road surface.

I use 150-CW grade but it doesn't matter, just use any sand paper enough to blunt off the grip tape surface.

Try it, before stick the grip tape on the roller don't forget to sand paper it to trim the roughness first so that i will not shred the tires. ;) Mines worked and no longer need any tape placement or maintenance. Perfect! :)

Oh, not at all, my tire not damage nor wear after a month. If the tire already made friction on the road everyday why not just do the same thing with the roller. So the idea hit me and i use the grip tape. All i did just use sand paper to trim (blunt it) the rough texture on the tape to match...

Hey there EMGX, i can answer that since i got the PRO version and ordered firectly from Qiroll official website. The motor roll Qiroll Pro do make some electric noise but not so noisy and not noticeable to people around me. Frankly speaking i feel my bike are far more stealthy than normal...
