My overall opinion is, that I am happy in general terms, but..... Maybe, your new batteries design like ipad model, and the suitable places to fix along the bike, would be better in stead of the "box battery" placed in front on my handlebar, that causes unstability with oscillations, when you loose yours hands. Another little problem that I solve atfer your recomendatios, was the cleanning and adjustment of the "connectors piano" between battery and handlebar connector to avoid the fluctuations in the continous power cycling assistance. Maybe the Brexit for the rest of the UE's countries, increases and feed the hardest burocracy customs and money uprised. When my battery comes to an end, maybe, I will get in contact again with you, for the new battery design buy. At last but not least, sorry for my poor english answers.
