orlieb ebike handlebar mount:Handlbar Bag. I have a Haibike XDuro Trekking bicycle and can mount rear panniers without any problem, but try finding and then mounting a handlebar bag that doesn't interfere with the bosch control unit (mounted on the center of the handlebars) or obstruct the front light. A possible solution is the Sackville Bar Tube bag from Rivendell Bicycles, but unfortunately they didn't have it in the right color with the delivery date of the desired color (Gray) unknown. The shape of the top tube makes it difficult to find a "cockpit" bag to use as a substitute for the handlebar bag. I've checked out gear from Revelate Designs (e.g., "gas tank" and "mag tank" and "jerry can") but don't think they will mount correctly given the shape of the top tube.
Lack of Water Bottle Braze-ons. To make up for the lack of bottle braze ons I purchased and mounted a Topeka Cage Mount to the handlebar and then mounted a water bottle cage to that. It isn't the best solution, but it better than lugging water on my back and sucking it through a tube.
Charging my battery. I really like my Bosch mid-drive system except for one thing - why did they design it so the PowerPack can't be charged while mounted to the bicycle? No work around for that - one has to disconnect the battery and bring it to the charger vs vice-versa.
