I use tubes from the brand Gaadi. ...works fine. You cut out the punctured inner tube and replace it with this sausage-shaped one. They come in a size close enough to the right one. You could continue using it as a fixed solution then. However, the small opening will remain noticeable.

In the past I could climb the same Dutch "hill" (3,2% slope) with 25mph with ease. And 500-600watt is a lot of course. I can maintain this only for a fraction of a second. ;) It feels that the bike only produces about 100watt. (It's a shame I can't see this figure at the screen) Luckily I'm...

The 2x500Wh batteries is giving me real problems now (20.000km, 28 mph version) The range isn't the issue, (yet?) it's the power delivery. My bikeshop measured normal voltages, but it's probably at load only. A little head wind or little incline combined with 400, 500, 600 watt pedal-power...

yet again a broken cable, fixed by the R&M importer. Still at 105rpm @ 45 kph. According to the importer is't due to wear and tear.

Still no working Bosch-engine. The update did not fix the problem. The bike shop (official R&M importer) is now trying to find the cause surrounded with a lot of self-pity.

The symptoms: - no response when I use the buttons on the handlebar. - The Kiox switches off in 1 minute. (=No power for the Kiox device) ...but strangely enough there IS a speed signal coming from the engine. Multiple error codes from the Bosch system. Currently it's at an official R&M...

8100 miles with my second bosch powered bike... And I encountered the first problems already. Just have to wait for the answer from Bosch if it's the hardware or software. (with 930 miles a month this is silly, not a decent replacement of a car of motorcycle this way)

The source is an official response of a Bosch employee. He expected the law to be changed in the future... etc. And with my limited knowledge; I don't now any other german-e-bike-engine brands. Stromer is Swiss for instance.

I have been told it's due to German law. The bikes have to reduce power ...far before... achieving the "real" 25 or 45 km/u. To make this less obvious the displayed speed is exaggerated.

@actaswu You were right about that. I brought my bike to the dutch R&M importer. 10 minutes work and it was fixed. 😒 My small town bike shop replaced the whole device... a waste of time and effort . The new harmony sounds ok. But I think I will stick to the manual one and replace the...

I have a 2019 R&M supercharger HS . It started with 80 rpm @ 45 kph. Which is fine for me! After a broken kabel (coincidence?) this became much much higher; 105rpm @ 45 kph. According to Enviolo a common problem. They replaced it (the whole device) and now it's spinning at 100rpm @ 45 kph...

I sold my bike with 17500 miles... the only thing ruined was the battery.

Of course only Bosch has the definitive answer. But 75% is the maximum assistance, and that's the info you get with this graph. - downwind the assistance is close to nothing - faster than 25mph the assistance is throttled back progressively

I received a fast charger... coupled with a R&M super charger or the other way around. :D I expected just a normal charger, but with 2x500wh it's no luxury after all.

ok, the "problem" was solved after the following update: drive unit: 1.8.3.0 > 1.8.4.0 battery 1.8.0.0 > 1.9.1.0 The next charge after this update gave me the "100%" for the first time. ;)

I get the same questions all the time, I don't mind. People are really interested. 1. How fast? 2. How expensive? 3. How far can you go on one charge? (good question, but too many variables)

Hi, not much extra info from this side... ...but I also have a Supercharger, not super-charging ;) to 97%. A first the Kiox-display will tell you it's 100%, but it's 97% after disconnection the adapter. Riding less than a mile this will quickly be lowered to 94-93%... after that it's fine...
