I recently bought a Class 1 long tail cargo Ebike. I had hemmed and hawed about getting one for years, and I finally pulled the trigger. And it has been great! I wish that I had bought it years ago. I have two young kids and riding around Minneapolis with them is so simple, easy, and fun. Obviously, I knew certain things, like going up hills, would be much easier on an Ebike. But something that I was not expecting an Ebike to do better over an "acoustic" bike: defensive riding around town is more relaxed and therefore more enjoyable.
Prior to buying the Ebike (and the birth of my second child), I had been using an old Specialized Sirrus (a fitness/hybrid style bike) with a rack on the back and child seat to carry my first kid. In this configuration, riding around town could be frustrating and scary at times. It felt like I could never make the timing of the lights. I'd have to come to a stop at nearly every signal. Sometimes, I'd have the signal to cross, but a car would cut me off anyways. Again, I would have to stop and then get going. Drivers would get frustrated with my slow acceleration. All and all, it was a lot of work and anxiety.
But with the Ebike, a lot of these issues don't matter. I can get up to speed faster, so I find myself making the signals more often. When approaching intersections, I find myself going slower than I did on the acoustic bike. There is no desire to try and carry my momentum like I had with the acoustic. The electric motor nearly instantly helps me regain it. So I'm able to approach intersections more slowly and cautiously, and then proceed through. If I have to unexpectedly stop, no big deal. I'll just downshift the internal gear hub and keep going. Easy.
Now, I'm not saying that an Ebike is plain better than an acoustic bike. Plenty of people will do just fine on an acoustic. But I am saying that they can be a better tool for a lot of people trying to get around Minneapolis. For all its high rankings as good bicycle city, Minneapolis still has a very patchy bicycle network. An Ebike can help most people smooth out the bumps of trying to get around.
It really has made defensive riding much more relaxed, and I was not expecting that. So if you are like me, and thinking of buying an Ebike: I say do it. As expensive as they can be, they are still the fraction of the cost of a car. And even if you already have a car, buy an Ebike and just plan to hold on to the car longer than you would. You'll be surprised how much you use the bike and how often the car stays home.
