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

    It's been quiet here for a while so here's a bit of an update. I did a bit of testing of the non-Qiroll friction drive and hope to do a longer test ride on a 15-20 mile hilly route tomorrow. It is much more powerful than the Qiroll Mute, automatically retracts from the wheel when not in use...

    Show us pictures of where you ride your ebikes!

    Columbia river gorge in Oregon from Troutdale Glenn Otto park east to Bridal Veil falls and back. I had planned to ride futher east but there was construction delays past Bridal Veil. There are some steep grades, thankful for ebike assist on the climbs and a heavy ebike makes for thrilling...

    Yesterday was a sunny warm day for a ride, 27 miles round trip with 2500ft elevation gain.

    Has anyone tried building a hub motor wheel with your rim? Is it complicated?

    You guys crack me up. There's no adaptor that would make a drop out hub motor work with a thru axle frame although there are adaptors for standard thru wheelhubs to work with drop out frames. And as I've posted before there is a torque sensing thru axle compatible aftermarket kit that works...

    Has anyone tried building a hub motor wheel with your rim? Is it complicated?

    Keyde makes a thru axle compatible rear hub motor that has torque based assist (and reported to have an inclinometer to help on hills?). Appears to be a very clean install because the controller is enclosed in the motor housing and has a wireless control so the only exposed wire is to the...

    Has anyone tried building a hub motor wheel with your rim? Is it complicated?

    My BH gravel "X" mid drive ebike has 24 straight pull blade spoke wheels. No broken spokes but the thing I like about them best is that if I ever have a broken spoke it can be replaced easily roadside without having to remove any hardware like cassette or brake disc. I carried a couple spare...

    Riding without the motor

    I'm not advocating for anyone buying a Qiroll friction assist motor but it could be a solution for someone who doesn't need the capability, or want the weight, of a traditional ebike but would like occasional assist. Total weight is ~3.5 pounds including battery so a typical aluminum bike can...

    Nice day for a ride yesterday on my favorite bike, a Walmart Schwinn hybrid that I've had for many years. In the past I've added a mid drive TSDZ2 with performance approximating a Yamaha PW-SE gravel bike that I have. Unfortunately the TSDZ2 adds about 7#plus battery weight of 5-9# depending...

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

    I found the stock Qiroll two button actuator difficult to use while wearing gloves, the old version with a toggle along with a mode button would have been better for me but unfortunately discontinued. A while ago I made an actuator switch with these momentary push buttons. It worked well but...

    Any update on the more powerful Qiroll prototype that you are testing 3dxl?

    REDUCE AIR PRESSURE WITH TANNUS INSERT!

    I've used Tannus Armor in both Schwalbe G- one 700x40c at max 70psi and Continental Doublefighter 700x37c at 80psi (max for that tire is 87psi). No problems with either tire blowing off the rim. I've also used larger tubes than recommended without an issue. They are some sort of foam so they...

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

    I gave the Qiroll Mute Plus another test run yesterday on a 19+ mile ride that doesn't have steep grades - total 600 feet elevation gain per Google Maps. The battery wasn't fully charged at the start but all 4 indicator lights were lit, at the end of ride one was lit and another flickering. I...

    What assist levels do you usually use on e-road bikes?

    Strange, their own web page description states 55nm with no mention of 23nm. Maybe a matter of max vs continuous or to meet regulatory requirements. https://www.scott-sports.com/us/en/product/scott-addict-eride-30-bike maybe you'd need to test ride one to see how it works for you.

    What assist levels do you usually use on e-road bikes?

    I think that I saw you quote that torque value before - but from their specs they state 55nm which is substantial boost. At your weight a 10% slope should be a piece of cake with that bike. BTW here is another screaming deal on a '22 model year medium...

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

    There are pictures of carbon bikes with Qiroll installed including one somewhere in this thread. Some people have used what looks like a putty substance between the attachment plates and the carbon tubes, I assume for protection - I'd be cautious to avoid crush damage. The roller can be easily...

    Any recommendations for a lightweight ebike conversion kit for road bikes?

    One very last post +2, but this time I mean it. Good luck and I hope you end up with what works for you. If you mean too heavy the motor itself adds 5# (minus the weight of your bike's current hub), the 7ah battery <3# - if listed weights are accurate. So if your current bike weighs 18# you...

    Any recommendations for a lightweight ebike conversion kit for road bikes?

    I don't think it is "fake", it's just the way they made their motor work with a thru axle frame.

    Any recommendations for a lightweight ebike conversion kit for road bikes?

    One very last post on this thread. OP, post up what you decide to do, if anything. I see the Keyde, laced into a 700c wheel with phone app and no battery, is now on sale for $516.96 and there is an AliExpress $70 discount listed for a total of $446.96. Battery sold separately or choose your...

    Any recommendations for a lightweight ebike conversion kit for road bikes?

    It sounds like you want a Mahle system and assuming you like your current bike why take a chance on disappointment and regret buying a $1000 - $2000 add on kit when there are better options for a complete bike for not that much of a premium? video worth watching for scenery alone...
