    Nice stealth setup, barely looks like an ebike. Keeping things looks like normal commuter bike.

    Looks very minimalist, i like it. Stealthy front motor hubs looks like classic drum brake. Is that led strips around the wheel spokes?

    As a guy who ride fast daily and brakes a lot on Qiroll Pro down the hill don't put 100% trust on regen braking to slow you down completely especially on heavy bikes. Pros: Its slow down "linearly" and recharge back the battery pack. Cons: It doesn't slow down heavy bikes above 20kg especially...

    Definitely agree with that, sometimes when i use regenerative brake button to brake i didn't realized it actual change sport/boost (Red led) mode to eco (Blue led) after experiencing slow paced ride. To confirm i have to bend down to look underneath the bike for LED light confirmation. Hope...

    400W+: Try to install but.... So i did test the 400W+ QIROLL yesterday but i find there some issues. Too long/protruded to fit on standard bicycle such on road bike, gravel bike or other commuter bike with short chain stay. The clutch already extended to max angle. You can see from the...

    Yes it from Qiroll. I don't have permission to reveal it yet but definitely i saw it and will do a test once it arrive at my door step. They didn't have name yet for their new unit, its still a prototype. It claimed to be able to conquer steep hill with power wattage over EU regulation. If...

    The Pro 320W performed well in all weather condition after many months of daily ride. I haven't wash my bike since last installation. It took it all the dirty grimes and soot very well and still perform excellent. Speed dirt is everywhere. I had no complaint. Its perfect! Time for me to clean...

    I saw the setup, looks bigger and bulky than Qiroll. If they make it compact and smaller i might pick one up and mix with my hailong/bafang battery pack.

    How much gradient hill climb you tried? What battery you use? Your setup look perfect, i don't see any problem. My Pro version could keep up climbing between 10% to 20% hill gradient moving at 8~15km/h with 50% leg pedaling effort (34t front chainring and 32t cassette on the back). Does your...
