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

    Hi, Kouzou: I'm glad the Qiroll system is working out for you. As for the motor's durability, I understand it's virtually indestructible and should last for years. I actually went over a curb and it hit the motor and left a dent in it and it's still working perfectly. It's about a year now...

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

    The tire will engage with the motor as long as the roller is touching the tire and moving in high power mode. It will give you a slight boost. To achieve a constant full boost you must constantly depress the power button, which is no big deal as the button can be positioned conveniently...

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

    The qiroll is VERY quiet...it isn't till the rubber friction tape begins to come off that it makes noise as it hits the motor when it revolves. The friction tape is rated to last anywhere from 300 miles and up to 400. That's the weak point of this system. I have no double the pro model is...

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

    I didn't even know they came out with a 320W version. Thanks for telling me. Because of all the fires and cold weather I have not been riding as much. My review stands as it is and I stand by it. It's a wonderful power assist. If the 320w version is even more powerful I'm for it! Although...

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

    Hi, Good question and the best person to ask that would be the one that sells the kits on ebay as he speaks Chinese and English and can give you an answer directly from the manufacturers of the motor. Search 'Qiroll electric bicycle kit' on ebay and contact the seller. BTW, is the purpose...

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

    Hello, You're welcome. Around where I bike there are tons and tons of electric bikes. You know those big fat tire bike with the powerful electric engines that go 30-40mph. Those are just too fast! I don't want to go 30-40mph. In truth, I don't even want to go 20mph. 12-15mph is a good...

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

    UPDATE... After 2 months of use, I have found the weakest point of this bicycle kit - the friction tape that comes into contact with the tire. The tape has an expected life of about 400 miles on road use. Since I also ride some bicycle trails that are paved but have occasional spots of...

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

    Thanks...yes I am having fun with it. The pressure of the roller against the tire is important so that there is constant contact between tire and roller and hence the most power transfer. The throttle could be better designed with a light indicator that shows you what mode (eco/power/sleep)...

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

    (By a bicyclist with a common man's (not an engineer's or bicycle tech's) POV regarding bicycles and motors used to assist bicycling. In other words: Press button - how fast can it go and for how long, and will it take me up that damn hill without too much effort on my part.) I was looking...

    Qiroll Friction bike kit

    Hi, Harry: Thanks for replying. I've read a review of this Qiroll kit on Alieexpress and it appears to be pretty weak and when no pedal assistance, it might go 8-10mph. Maybe that's enough for my purposes to get up that hill, I have a moneyback guarantee so I might take a chance. Also...

    Mini vs Full Size Bike for Seniors?

    Hi, I realize this is an old thread but I couldn't help but jump in. I am a senior and was looking for a small folding bicycle that would be light and yet ride like a full size bike and be easily collapsible to put in the trunk. (I have a Honda Civic and they have really small trunks!). I...

    Qiroll Friction bike kit

    Hello Everyone: I have a folding 20" worksman bicycle, 7 speed internal shimano, and it's great for those under 7 mile rides. However there is a hill or 2 that make that a bit difficult. All I wanted was some assistance to tackle those hills. I didn't want a heavy front wheel hub motor kit...
