    interesting issue with Nyon between bikes.

    I use several Nyons (first generation, the oldest one is from 2014) on multiple bikes with different generations motors (2, 3 and 4) from 2014 to 2021 and I don't know how many different batteries. Never had any issues, it just works fine. The customized screens update immediately when switching...

    Battery dropping fast after charging. Hum ??? BOSCH Li ION PowerPack 500

    Yes, that is the best way to figure out the remaining charge. You will get a feeling for how far you can go with each LED. The last one is of course a little less as there is a reserve for the light left. If there is only one LED left, it is time to get back home. Since I am using the old Nyon...

    Battery dropping fast after charging. Hum ??? BOSCH Li ION PowerPack 500

    Correct. And for me it does not work anyway because my 400Wh batteries are 500Wh and one of the 500Wh is actually 1kWh. But after over 10 years with the Bosch, I do exactly know how many batteries I need on a camping weekend. But more important: I know exactly how far my ebike buddy can go on a...

    Battery dropping fast after charging. Hum ??? BOSCH Li ION PowerPack 500

    Yes, that works if you are riding a pretty simple profile - continuous speed on a flat road. If you are doing a lot of uphill and downhill, it will change all the time. Just imagine this: you ride the last 15 km flat with tailwind over 25km/h (or 20Mph) with your battery below 10%. It will...

    Battery dropping fast after charging. Hum ??? BOSCH Li ION PowerPack 500

    As we explained before. You erased the memory of the last 1.5 miles of use. It has to start with some realistic range and starts calculating again as soon as you start riding. It can not look into the future and know how you will be riding. Those range numbers did start the longest threads in...

    Do the same when it displays the range. Press and hold the RESET button.

    Depends on what computer you have. You can find it in the manual.

    Troubleshooting Ebike Lock

    Just FYI if you want to use the lock function (I don't use it for a reason). I was out on a 3 days trip a while ago and forgot my USB-C charging cable for the phone (no big deal, I just turn the phone off then). But imagine going up those hills with all the camping gear with no assistance after...

    Battery dropping fast after charging. Hum ??? BOSCH Li ION PowerPack 500

    If they buy the well overpriced capacity tester. I only paid 1/4 of the US dealer price for that thing in Germany. The dealers will charge you an arm and a leg for just checking the battery.

    man getting the tandem wired for two batteries is a bit crazy.

    We have done the dual battery setup on countless motors and there is definitely nothing the Bosch rep has to configure (or even can configure - I have configured motors with them). However, the most important part is that it works. My easiest dual battery conversion is to connect a second...

    man getting the tandem wired for two batteries is a bit crazy.

    All motors from 2016 or later support dual battery. But it is always good to do a software update (no need to call Bosch for that though). Also the batteries require a software from 2016 or later to support dual battery setup. The one with the higher charge is the active one when turning the...

    Battery dropping fast after charging. Hum ??? BOSCH Li ION PowerPack 500

    This is how it is supposed to work. The system cannot look into the future. It is recalculating all the time based on the past minutes/miles of riding.

    Battery dropping fast after charging. Hum ??? BOSCH Li ION PowerPack 500

    So when you have 25% left in the battery, you just turn it off and ride back home with no assistance? There is a BMS, Battery Management System in the batteries. And it works really well so you don't have to waste any time thinking about how to manage the batteries. Just ride and use them and...

    Battery dropping fast after charging. Hum ??? BOSCH Li ION PowerPack 500

    You can reset this at any time. It will adjust according to how you are riding and draining the juice. I am riding Bosch for over 10 years and never even looked at the range. After riding it for 1500km you should already have a feeling for how far you can go. If there is only one LED on the...

    Low Battery Cutout for Bosch Gen4?

    Confirmed. I have my bikes all set to 3W (lowest) as we are usually riding with multiple batteries. And rarely in the dark. So even if the light would drop the battery to 0%, we could just swap the battery.

    man getting the tandem wired for two batteries is a bit crazy.

    Those Gepida tandems were always a pain to get the chain and gears adjusted. And if the battery mounts are not close enough to each other, you will have to cut and extend the battery cable anyway to get it all connected on the Gepida. I would have spent the extra $ for the Moustache tandem which...

    Bosch Solar Charging

    It does. I have a brand new 625Wh horizontal PowerTube but no bike for it. Unfortunately nobody wants to buy it.

    Bosch Solar Charging

    Correct. And a car USB charger (12-24V) connected to the solar panel side (input) to get the 5V signal. That signal only goes to the first battery. From there you need the CAN bus connection to the second battery and of course the power connection. As soon as one battery turns on, they talk to...

    Bosch Solar Charging

    Parallel charging of two 500Wh Bosch batteries with a 50W panel. Works just fine, takes just a bit over 4 days until both batteries are 100% charged. After both are fully charged, they just turn on and off every few seconds which is no problem. Even with a smaller 30W panel I could create a...

    Now I know why my motor rusted.

    This is known since 2016. You can even get a replacement kit from Bosch (includes the right motor cover, bearing etc.). I already replaced that bearing on over 20 motors and always add that ring and grease. This plastic ring became standard on new motors later. Here you can find my post in the...
