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

    Nice job with your mounting solution! Just messing around I've put my Qiroll on 4 different bikes in several mounting locations and like best on the seat stays where possible. That way I could easily look down and back at it to see what mode (red or blue) the motor was in as it wasn't always...

    I bought a few of the waterproof momentary lever action micro limit switches and since the braided USB micro cords came as a pack of two I'm going to make another controler using them. Both the push button and lever action switches are much easier to feel and hear when they have been...

    BTW, nice bikes and I'm envious that you had the foresight to buy a Pro instead of Mute, wish I had. Edit: I took a small ride with the DIY actuator and like it. As a bonus the braided cable is somewhat stiff unlike the floppy OEM so routing is neater.

    I just bought what was convenient off of Amazon, two pack of stick on push button momentary micro switches. There are a couple sellers of the same product for $10 or less. Not waterproof, the lever switches that I may or may not try depending on how I like the current setup are even less...

    The DIY switch that I posted above works with same functionality as the stock S2 control. If I like it I'll leave it, if not I might try lever actuation momentary micro switches instead of push buttons or one lever actuated for the "throttle" and a push button for the "mode" selector. Easy and...

    Crater Lake Ride the Rim

    It's a great ride that I try to make every year when life allows, I never get tired of it. It can be done on regular non-closure days also but more fun with the east rim and road to Pinnacles closed to car traffic. This year there were fewer riders which was nice, but even on busier days it is...

    Thank you blueberry. I'm not interested in a brake cut-off myself but I dislike the S2 control so I'm going to see if I can make my own. Ordered a 6ft braided USB micro and a couple momentary push button switches that should arrive sometime today. Plan is to put one button on each handlebar...

    So allow me to show my ignorance. If the Qiroll switch is normally open couldn't you just put a simple in-line on/off switch in series with a normally closed brake cut off switch and avoid having to use a NOT gate (I'm not sure if there are normally closed brake cut off switches but I've read...

    Buck converter worked for me. Enclosed in a handlebar bag it didn't even get warm. Since these motors draw low current there are Buck converters for the load. I did find a 36v output Buck 10a max (not sure what continuous it would support) that might work with a pro but I'm more wanting to...

    I re-read your posts from back in 2022 and see that you are the one who also reported that the Pro wouldn't run on >38v which is only 3v above the 35v charger for the stock 33v Pro battery. Maybe 36v would work (two 18v power tool batteries in series)?. I've run my 24/25v Mute version on 24v...

    Thanks for the reply, beyond my ability to replicate what you did but might be something that someone else could accomplish. Do you have any suggestions regarding Tuono's switch alteration question? Regarding the friction tape, it sounds like most Qiroll users have similar issues with the...

    Here is a link, not what you are asking for: https://github.com/edasmalchi/qiroll-pedal-assist Apparently he was trying to incorporate a cadence sensor and brake cut out.

    I haven't seen anything that was reported as sucessful. At one time I did see one blog post where someone was attempting a revision but provided no follow up - which makes me think that perhaps it didn't work out for him. The S2 activation control leaves something to be desired.

    I hope that the friction tape works well for you and you post up your experiences one way or the other. I've mentioned before that it didn't work for me. I started with a generic product, then 3M Safety Walk and finally Gorilla brand. The grit on all three quickly wore off exposing the...

    I'm not saying it'd work, but maybe a step down to actual 36v could possibly work with the 33v Pro. You'd have to check but I think a prior post several pages back indicated that 38v didn't work but maybe 36v is close enough? Personally I don't think that I'd risk it but I did use a similar...

    Just my opinion but I wouldn't worry much about physically disengaging the drive unit unless you ride in mud or other debris that you don't want to wedge between the tire and the roller (I addressed that somewhat by mounting the unit on a spring base so it can be pushed away from the tire...

    The Mute Plus does have regen, it just isn't much, when it's activated regen slows the bike to a small degree. No idea regarding the Flex version and I can't comment on performance with the Pro other than what I've read as I've never used one. You're probably better off directly asking Jason...

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

    Yes and no. My Mute Plus does have working regen and while it doesn't gain charge or slow the bike much it is slightly noticeable on long downhill runs. Both of the buttons have to be pushed and held at the same time to activate regen. Regen (and the associated braking) is supposed to be more...

    Interesting that Shimano Steps will work on batteries without data ports to communicate with the Shimano controller. Is this the battery? Light and small. You do have to stop to disengage the Qiroll from the wheel. It keeps running in the "electronic clutch" mode until you've slowed down to...
