    REVIEW: QR-E 250W ELECTRIC BOOSTER BICYCLE MOTOR AND B60i AND B70 BATTERY

    Yes, i apply tape without removing the motor. Just de-clutch it from tire contact. Its just 3 minutes work to put the tape. I don't have the link because my next door office sell this industrial floor tape so i don't have to order online. hehehe!

    Yes, you need to press the motor hard to the tires, don't let it loose else it worn the tape in an instant. Not sure about normal MUTE motor but my PRO motor even at high press on the clutch it still running fast without load. My tire and roller still exposed to grit and mud but doesn't wear...

    Yes, as seen over 2 years of conversation in this forum i've using that floor grip tape with zero problem. 100% success over various weather including rainy days. Regardless it won't wear your tires. Even yesterday my local bike shop looked at my rear tire says it looks like new even have been...

    Have anyone ordered anything from Qiroll lately? What the ETA time from order to receiving stuff at hand? My late given tracking number given by them last week doesn't work. Expected to work on my QR-E Pro installation this week so i can show off to my office colleague for e-commuting.

    As shown from previous page and discussion i use 3M industrial floor grip tape, have rough solid surface almost like sand paper but really grips and non-slip on roller. Feels faster, impossible to slip and really works in rainy condition. You can feel more torque and assisted power when...

    Go QR-E Pro, you won't regret it. Its a whole new experience making commuting more sensible for me. About S1 and S2, i can't comment much because its a compliment optional package from Jason from backend request rather than front end shop. I'll have to wait for the parcel to arrived to see how...

    The locals get used seeing me on the road daily for years so its normal to share the road and slip through. Yes, can't wait to see Kinhsang review on how it roll on knobby semi slick mtb tires but can be a struggle if the tires are made from hard rubber compound. Schwalbe mostly made to be...

    Still waiting for their reply. Btw mine comes with S1 control and has USB-C connection to the motor unit. I really like S1 because i can easily strip bare bone and slip under the brifter/shifter rubber hood for stealth looks. *Btw i can't pull the connector out, its stuck there with dirt and...

    Sound like good counter measure protection built-in the unit from overvolting above 38v. Good to hear. How much was the Pro model on Ebay? Was it from legit Qiroll vendor/seller? I was thinking buying just the roller unit than with battery attached. My two H70 300Wh battery performed well...
