Hi All,
I've been lurking on the forums for a while but this is my first post. Sorry in advance if I'm breaking any rules or asking something already answered. I've been researching to build an electric bike using a purchased road/hybrid bike and a bafang motor. Mostly, I plan on using it for commuting with a mix of day rides around cities. I'm going to buy the bike first and then buy the middrive (probably a bafang bbso2) later this fall, but I want to try to make sure everything is compatible before buying the bike. The bafang and a battery is ~13 pounds, and I'd really like to keep my bike under 40 lbs and lighter is even better because I'd love to use it (without being annoyed by the weight) with the motor off as well. Also, from what I've read, disc brakes are a must. I'm 6" 1' with longish legs and my lower back tends to hurt on aggressive bike frames, so I'm looking for a bike with a more endurance or comfort geometry.
So, two questions can I go with a carbon frame bike or should i stick to aluminum? Any thoughts on the below bikes generally and would they be compatible with a bafang middrive? From what I can find, Bafang middrives are compatible on any bike that has a 68 mm bottom bracket...but I feel like I'm missing something.
