Really? that is awesome 👌 thank you so much mate

Best regards from Denmark

no problem. keep in mind that a battery that large 10kg, a whopping 22lbs will make your bike quite a bit heavier and cumbersome. not ideal for mtn biking, DH/XC or anything rough. smooth roads for touring? just fine. also im guessing with 1960 watt hours you could get about 50-80 miles of range on a charge dpending on how efficient you ride and the terrain. it will take a long time to charge that battery so, if you do go for it, i would opt for the highest Amp charger you can get for 52v batteries - more amp current on the charger = faster charge time. i opt for lower weight batteries and get a couple of them. but it all depends on what youre aiming for.

My trip starts in Denmark and ends in Switzerland, so lots of mountains and stuff, but I'm sure I'll encounter some dirt roads along the way.

I really hadn't thought about the weight issue, I'm not even sure, that the frame can take the weight of my fat behind (209lbs) the motor and the batt.

I think the max load capacity on the Marin Gestalt x10 gravel bike is 264lbs. So no luggage.

bicycle trailer is my only option for food, tent etc.

Thanks again for your expertise
