I am looking to "e" my wife's tadpole. I would much rather go with an "assist" system than "aux power" type system. My searches have only turned up the BionX, which on first appearances seems to be a good system...until you dig a little deeper. I find that there are some significant quality issues with the wheel build, and also some serious issues with battery problems exacerbated by the shipping regulations on them.
I don't know if the problems are a real issue, or just more being made of them than what they really are, and have yet to find another (affordable) system that does the same. I have noted that Bosch has a system like it that doesn't appear to be set up for use on a 'bent, nor can I find a price on it...which usually is along the lines of "if you have to ask".
I had started off considering a mid drive system, but find they are out of the price range I would like to stay in. The BionX offers features and price I like, but am concerned about the quality and replacement part issue. Is there anything else I should be looking into?
Just for reference, the bike will be ridden no more than 10-15 miles at a time on relatively flat ground with a light rider. Bike and all will be under 180#.
