Your hinge looks like it might be galvanized/zinc steel which should drill fairly easily with standard drill bits if they're sharp. If it's stainless then cobalt bits might be necessary (Home Depot has a sale on a good looking Milwaukee cobalt drill set this weekend). Use a center punch to...

When I submitted a warranty claim they sent a automatic confirmation email and contacted me back and resolved the claim shortly. Maybe warranty isn't applicable in your case since it is a North America warranty and you purchased from UK "we offer a comprehensive warranty policy on all Schwalbe...

My first thought is that it is a stone bruise causing damage to the internal plies and bulging of the overlying rubber compound. Regarding Schwalbe warranty, I had a 2 year old OEM Schwalbe G-one with a couple thousand miles on it, but with substantial remaining tread, that developed cracks in...

Still trying alternatives to the stock control switch. This time using latching pushbutton switches instead of temporary blade. The mode button can remain latched for the regen function or blipped on then off to switch between low and high assist levels. The other button to actuate boost...

Just for the sake of discussion, not really for the OP for whom this all seems to be a thought exercise - besides the Keyde torque sensing 142mm thru axle compatible rear hub motor kit (which is 2 pounds heavier than the Mahle hub and offers 35nm torque vs Mahle 23nm) there is the ultra light...

I didn't so much like the qiroll hanging down from the kickstand bracket so I attached it from the topside. Less prone to damage and looks better to me.

Interesting, post up when you get your custom printed adapter - I hope it works out like you want. I had my reasons for the non Qiroll purchase but my experience with it is a reminder for me to not have a credit card close by while browsing on the computer with my morning coffee - lesson learned...

The spring hinge is 3" stainless steel that I got off Amazon. I needed cobalt drill bits to make the Qiroll attachment holes and one for a bolt to the kickstand platform, if you don't have cobalt bits it might be better to source a hinge that isn't stainless. I have used a similar 4" hinge on...

Would the Qiroll quick release help with your folding/seat post interference issue? It's not expensive, $24 USD. At one point I installed my Qiroll on the front fork of a 26" bike that had an easy install unlike your Brompton. It seemed to work as well as it does on the rear wheel (caveat, I...

The non-Qiroll friction drive in the image above burned out after 7-8 miles of riding on a hilly route. Up until that point I thought it worked pretty well with significant assist although I was putting in a good amount of effort pedaling. It died suddenly on a 12% incline (per Garmin) in...

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...

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.

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...

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...

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...

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...

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?
