E-bikes mostly use motors and battery options from a few major suppliers: Bosch, Yamaha, Shimano, and Brose. A few other brands exist, but are less reliable or powerful. Some, like the Yamaha system, have more torque, and others, like Bosch’s Active Line, are nearly silent. But, generally, all four make good options. Look for motor output (in torque), which will give you an idea of total power. Just like car engines, more torque equals more power off the line and more boost to your pedaling. But watt hours (Wh) is perhaps a more important figure to use—it takes into account battery output and life to give a more accurate reflection of power (higher Wh equals bigger range).
The gears don't seem to keep up on this bike. There are 21 gears, same as my other bike, but there is much more resistance at the highest gear on my other bike going 20mph than there is on this bike. The reason that is an issue is that during pedal assist, the bike goes pretty quick and I don't want to be pedaling air, I want some, just a little, resistance. I don't know the mechanics of it or how this would be the case, perhaps because this bike has smaller wheels than my other bike? The bike came pretty well adjusted on the derailleurs. I haven't touched the back but the front I've had to mess with a little. The chain fell off outboard once, so had to adjust. Chain guard did its job well. The chain got stuck pretty good, but once I loosed the chain guard everything was easily moved.
