I love those DIY separate buttons. I might do one in the future if my buttons fails.

Let us know the speed, hill climb performance and battery compatibility. Waterproof?

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...

This month i use the flat route. I'll post it if i use the hilly route. ;)

Enjoying my Friday rush hour! Video: https://x.com/SupermotoXL/status/1852313023761010770

Yes, i pressed the roller really hard so that it won't slip and won't worn out the tape, consequently startup pedaling can be a bit stiff but get easier to pedal when it gain rolling momentum. Yeah, i didn't follow Qiroll recommended setting. Another thing is that if the tape exposed to water...

How fast can you ride with 16" with that gear ratio. I have similar gear ratio with Shimano Tiagra group set ready for my folding project. (have problem with dogs around the neighborhood). I can't wait to see how you install Qiroll Pro on this frame. Btw yes Qiroll Pro need to be adjusted...

Should be no problem with quick release adapter if you wanted to be frugal with one unit of Pro swapping about. Btw i love your folding bike, that's the one i'm planing to get for next Qiroll Pro project. I'm aim for Fnhon Gust brand model like yours, looks identical. Is that a 16" wheel? ...

I can't recall if i posted that hill climb video on twitter, however its always keep on pedaling 40% effort with the throttle button keep pressed on giving me a crawl speed of 10~15km/h up the 20% gradient slope reaching around 80 meter elevation.

Yes i've seen the Flex but due to my nature doing daily commute and brushing with road traffic i need 320W for safety reason and getting good sleep after few hill climbs. I don't want muscle pain and get chased by dogs. ;)

Better get the PRO version with H70 battery pack if you wanted to experience actual ebike performance. Its kind of dangerous to use external/non-compatible battery mated with PRO because if the QIROLL PRO unit does an accidental re-gen activation the battery will get hit by unwanted 'recharge...

Yes! That's it! Go get one. When you get your Qiroll try the original friction tape first and ride everywhere including pedalling up the hill before install the 3M to experience the ride differences between each type of tape so you can appreciate the differences. ;) *Ps: Wow $13! Mines just...

I think you should get 3M floor grip tape from local hardware store better, you can test several type of surface rough abrasion that suits your tire and cheaper per-roll tape. Here i can get it around $1~3 per-roll which can last me 1 to 2 year of use. Like this one...

Qiroll Pro: 3M floor grip tape is a must do mods if you wanted to experience 1:1 power transfer ratio full torque transfer to the wheels even when not use for hill climbing or riding on wet road. On stock default supplied friction tape; when riding on flat road i can feel it slipped losses 40%...

I wouldn't recommend voltage regulator unless you know the peak amp (A) current consumption required between the battery and drive unit. Else i would love to use back my 52V 17Ah bafang battery pack on my Qiroll unit. You'll need to contact with Qiroll support, they have engineers on how to...

On my H70 battery pack with continuous pressing the throttle/boost button on my way to office + mild pedaling + half km 20% gradient hill climb + 14km (8.6 miles) trip = consumed 2/4 blue bar on the battery. Means 50% of the battery pack consumed for that mentioned trip. Better to have 2x...

Oh yeah, my fast white stallion (Qiroll Pro) still doing well everyday on the road.

Hi, Sorry for not being here in this forum. Btw for hills PRO is a winner, but you'll have to ditch the manufacturer friction tape and go for those DIY mods using 3M industrial floor grip tape on the friction drive roller else you will loose around 30% torque power slipping all the going way up...

It should fit on Birdy MK2 below rear stay behind the tires, i can see lots of ample space to mount there so no problem. As for assist mode either both ECO and SPORT; if you clutch the friction roller on the rubber tires lightly according to installation manual you can easily pedal without much...
