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

[Tuono]

They list weight as 1.5kg, not sure if that includes the control.

Not to bad. I'd give up a couple of lb's to not manunually engage every time.

Przykro mi to słyszeć. Czekam z niecierpliwością na obejrzenie Twojego filmu.

Juz wszystko ok bateria była na maxa naładowana dlatego nie działa hamowanie silnikiem jak poziom spadnie to bedzie ok wszystko

How do I translate karkodup86 messages into english?

 

[EMGX]

Google translate. It'll even translate text in images which is amazing.

No i zamantowane przetestowane teraz człowiek myśli nad wersją pro

 

[EMGX]

I'd be interested in the Pro too but I'm not going to spend over $500 just to find out if it would be adequate for my use or not. I ordered something else instead and when I recieve and install it I'll post up my experience, good or bad, it'll probably take a few weeks.

Byłbym zainteresowany również wersją Pro, ale nie zamierzam wydawać ponad 500 dolarów, żeby się przekonać, czy będzie odpowiednia do mojego użytku. Zamiast tego zamówiłem coś innego i kiedy ją otrzymam i zainstaluję, zamieszczę swoje wrażenia, dobre lub złe, prawdopodobnie zajmie to kilka tygodni.

To co zostało zamówione pochwal się

I did end up buying one of these. Weighs almost 4# which is heavier than I would have preferred but it has a very solid feel to it. There a few versions of this type friction drive that I have seen on Ebay and AliExpress. Mine has an interesting control which not only has a thumb throttle but 5 cruise control settings and brake cutoffs whereas the other common control only appears to consist a thumb throttle. The servo clutch seems to work well providing adequate pressure on the tire but I've only test fitted it on a bike while on a stand so I don't have any idea of actual performance at this point. I'm cautiously hopeful that it will provide better assist than my Qiroll Mute Plus.

Let us know the speed, hill climb performance and battery compatibility. Waterproof?

It's IP67 rated which seems pretty good for this type device.
I'll post up my impressions, good or bad (hoping for the former).

Any luck yet with the new system? Love the electric servo. I had a little more luck with my flex after but still working on it. The switch is a real pain, you guys think a simple toggle to keep it on could work....I hate holding it down

Weather isn't cooperating with riding right now with cold temps and ferocious wind which is typical seasonally where I live. Given the time of year I might not have much opportunity to test until the odd nice weather day if I don't have other plans or spring. The throttle mechanism seems well thought out in that besides the thumb throttle there are + and - buttons that allow for toggling between 5 levels of continuous assist along with brake cutoffs (besides a shut off button) so a quick blip of the brakes cuts assist. I'm hoping it will work well enough to use on train and ride plans for the spring/summer. Amtrak has restrictions on ebikes so that even my Yamaha powered bike technically wouldn't be allowed as it isn't UL approved. This friction drive is much quicker and easier to install than the Qiroll so I'd carry it seperately from the bike and install it at the destination.

I finally got around to make the DIY S2 switch with the 2 flat buttons that EMGX recommended. It feels much more natural on the grip. I haven't had a chance to really test it on a ride yet because the weather has been below freezing temperature. I also ran the micro usb cable inside the bike so it looks much nicer now.

 

[EMGX]

Not surprisingly the stock friction layer slipped some on a wet tire so I decided to try something else.


When I get another chance I'll retest it.

BTW the throttle mechanism is a step up from what Qiroll offers. Besides the thumb throttle there are 5 levels of assist that remain constant until either of the brakes are blipped which turns off assist and retracts the roller until it is reactivated or the thumb throttle is used.

Cześć. Kupiłem. Zamontowałem na tern verg d9. Dokładnie to, czego szukałem. Mam pytanie. Czy ktoś zna przybliżoną żywotność silnika? Teraz zamów akumulator b70 na zapas i na duże odległości.

Kurcze fajne ale qiroll lepiej wygląda bardziej dyskretnie
