I've had virtually no problems with my babymaker, the only thing I had to replace was the controller as the original one was overtightened and eventually the plastic cracked.
The bike rides much like a regular road bike and not some creepy coaster electric bike (think Aventon)! I replaced the seat, tires and handlebars since this bike is aluminium and every bump is transmitted through both. Otherwise it's very stock.
It seems to love working with the gatorskin hardshells that I put on it.
It was one of the best purchases I made last year.
