I'm currently looking to get my first ebike, and have a budget of $3-5k. I'll be using the bike everyday for commuting to my office in downtown Manhattan, and would like something that will be very reliable, comfortable/safe andfun to ride. As far as features are concerned, it seems like something with a removable battery would be ideal for apartment living, and i don't have too much preference between 20mph and 28mph-rated bikes so long as the drive system works smoothly (a belt drive and hub shifter would be nice if there's one in/around my price bracket). I’ve seen products from Bulls, Specialized and a few other brands that seem to fit most of what I want, but wanted to ask for some suggestions. Thanks for your help!
