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 so I've done a lot of research and found a friction drive motor kit with battery that comes in under 5 pounds and cost around $350.
I've searched all over and can't find any user reviews of this though so I'm asking anyone if they've tried this particular kit.
The website is: http://www.qiroll.com/
There are youtube vids of the kit, installation, advertisement as well. The seller told me the battery has 300 cycles till 80%. Which is good?
Also, from the explanation on the site and from asking the seller who is Chinese, I got the impression there are two modes for the roller in regards to it's contact with the tire. You can manually separate the roller from the tire. The other is where the roller is manually set against the tire and you can use the throttle which will set the roller in motion to get the assistance.
My question is, how much drag if any wouild one feel in this mode where the roller is in contact with the tire? Because of the language difference, I don't quite understand what the seller meant:
"QR-E uses a virtual electronic clutch to eliminate the resistance of the motor, and will not feel the resistance when installing the battery."
Anyone who has used this kit and can answer my question especially about the drag one feels when you are in the mode where the throttle engages the roller please let me know. Also, how well does it help you up a hill?
Here's a pic of my bike attached.
Thanks again everyone!
