Fail! Game over mid-drive! Time to switch to Qiroll Pro. Yesterday my n+1 bike mid drive Bafang 750w BBS02B started acting up half way on my commute route to work, the crank drive jammed and unable to turn ended up towing this heavy ass tank on foot around the town. Unable to pedal even...

Hey im back! Good to hear you can use non-proprietary 36v 15ah via step down. I wonder if we could just use raw 48v, might help increase extra KW/rpm on my Qiroll Pro? Glad you got your friction worked on hills. 2024 Updates: Lighter Qiroll Pro E-bike build (now 10kg full weight with...

Hey ordinator! welcome to the forum. Love your bike. Try the industrial floor grip tape, very strong adhesive too. Had 100% success rate and torture em on daily fast commute and wet rides over a year now. Feels like sand paper but it won't harm or worn out my tires, great for hill climbs too...

Try to keep the hinge look stealthy or clean minimalist look on your build. ;) I think for my first priority build i would ended up with a titanium bike as my forever bike that will stick with me till my old end. The build is still long way to go as i need to save up budget for custom chrome...

Have you try ride up hill and going fast downhill? My early DIY have similar like yours have a bit thickness but sputter at high speed going down the hill. Which is why now i prefer thin lighter layer. Hope it works well for you once your weather over there stabilized.

How many month is winter over there? Got roller or indoor bike trainer to keep that legs fit? Its very hard to ride safe here; unleash dogs, sandwich traffic and shared lanes are constant challenging task for bike commuter in this 3rd world country infrastructure. Anyways thinking picking up...

Hey i'm back, so hows the clutch project going on? Steady weather over here, no longer rains and starts to get warmer and hot. Still busting some speed everyday on my Qiroll Pro. Here video commute in the dark. Not much space to bike on the side of the road but the speed helps to sync with...

Can't wait to see your manual clutch fabrication, i think its a great idea to on/off the clutch mechanism 'on the go' to make the bikes pedaling feels normal without extra friction. I might dig into project too if i had time.

Morning Qiroll e-bike photography.

You guys have crazy weather over there, wind, tornado, typhoon, winter, cold and stuff. Btw if you get some wind behind your back on two wheels you can sail freely without e-bike kit.;) We just got summer for whole year; tropic island but causes our rubber tires freckled early than its original...

Back on my mid drive PAS system for commute, need to get my legs muscle moving again than scooting easily around, lol.

Nice! probably gonna try fly there to visit the place tonite in VR sim. :) 19kg is a good number on e-bike that rolls on gravel and off-road. Usually out of factory e-bike ready are around 25kg average and can be hard for those who live in high rise building lifting it and stuff. Hope you...

*Beautiful view on the horizon! What's the name of that mountain in the pic? Mid drive make sense for wet and slippery condition and great for hill climbing. I ride my Bafang 750w mid drive MTB if i want to do leg exercise or pure off-roading but i hate overweighted e-bike. But this season...

Ah!! 38 fahrenheit = 3.3 celsius. Thats it! Cold rubber doesn't grip well on anything; its surface harden and doesn't provide good contact with roller's stock grip tape even with diy floor grip tape. Its shreds the diy tape because hardened tire rubber eats it. Where i live 26~30 celsius is...

I have the feeling maybe their recommendation on tires doesn't count into wet condition scenario and others environmental factor such as slippery mossy soil. Some so called 'durable tires' are less likely to have good traction compound based on my experience riding with several commuter grade...

Is the Gorilla tread tape are same grade as rough sand paper like grip floor tape? https://www.gorillatough.com/product/gorilla-anti-slip-tread-tape/#product-details-accordion Yours looks very rubbery from the photo or is it other material? Is it possible your tire compound made from hard...

Hey all! Happy new year 2024. Just arrived office scoot around with my roadie on Qiroll around traffic this morning. Was after rain leaving with lots of puddle and wet soil, didn't get any slip and had solid torque. I suspect maybe type of rubber tire compound may play much role over grip...

The thinner the adhesive the better especially that already comes with the anti slip tape because it won't get slipped around if the adhesive is too thick. Don't worry about the roller, even in naked/without tape it can handle great amount of torture and abuse. My qiroll roller have been...

That looks quite thick after adding 3M VHB, i hope it holds well and and not squished on by its thickness once the roller clutch tightly on to the tyre surface. I'm sure you'll get 100% grip and anti-slip torque once the roller moves. You'll have great riding experience than default roller tape...

I ride almost 20 days in a month and only need to replace once (1x) the (DIY) floor grip tape.........that will be around 12x per year for just total of $2 per-roll. Cheap! Now already passed more than a year i must say the the floor grip tape is 1000% far better than supplied stock Qiroll...
