It indicated slipping = means the clutch is not tight enough. Mine still use 1x layer and lasts me few months.

Tips going up hill to avoid killing the friction tape > Use easy gear, slow down don't force pedaling more than what Qiroll can pull but try pedal sync to Qiroll speed. If both roller and tire rotate it sync and equal torque/force even in wet condition it won't worn the friction tape. Mine...

I think roller too tight. Here quick tip how to get it right depends (on type of riding you want: full boost or pedal). If want full boost while pedaling + non slip in the rain (my way) here's my setup: 1. Tighten the clutch, then turn ON the battery. Wait until the LED light turn "RED"...

Are you using Qiroll grip tape? Ditch it. Because even if you clutch it right it does not provide full 1:1 ratio power. Somewhere along the ride i can feel it wasted/leaked out 30% of the roller through slippage.

Well, have to live up to the jet sound if you wanted to continue using it unless you can send to Qiroll for engineer inspection. I'm sure they can help out.

For the MAX (400W) 13km x 2 way should be no problem. Hefty amount of power left inside H70 battery. I put my 400W (MAX) on my folding bike just to scoot around the town with zero pedaling. I don't put the Qiroll original friction tape..that tape fail me. I use 3M grip floor tape as...

I got there test demo version before they called it MAX, i did some comparison back several page in this very thread forum. It consume more power and good torque when climbing hills. Its a good unit but i don't like the size and weight. Just heavy and wider than Pro. Good use on heavy duty bike.

That Pro with whining sound i knew very well happened on my Merida (white bike), is it continuous? Mine like that, sound like jet turbine engine when throttle. I suspect the clutch mechanism inside making some scratches or something. Happened twice on same Pro unit. My other Pro so far was...

Clicking noise? Is it happened on Mute or Pro unit?

Evening, it started to rain... Video:

Morning power! my usual morning routine ride to work on Qiroll. Video:

This sticker is very useful if you traveling on board planes because they need to know battery ratings capacity before allowed on board.

Without the friction tape you'll lost lots of torque..you may not feel it but it slips a lot even when dry but super worse on wet roads like 0 torque. I ditch the stock Qiroll friction tape 4 years ago and go for 3M flooring friction tape (those looked like sandpaper surface) gave me powerful...

New battery tested, felt like super human again. Gonna order 2nd one so i could daily rotate its usage.

New Qiroll H70 battery arrived! Finally i need to replace my 4 year old H70 battery..nothing wrong still works but sag 2 LED blue bars (voltage sagging) when i ride just doesn't have that "OOmmpphh!" power like it used to recently this month. However consider this old battery have been survive...
