Price and performance aside, I find this to be a very interesting time for e-bikes. It reminds me of the pre-1920 motorcycles.
-So many types of motors, controllers and frames are being offered.
-There are so many companies offering e-bikes. Some are huge, like Yamaha, and other e-bike companies involve only a hand full of employees.
-I don't look forward to the time when the e-bikes are all pretty standardized, and a few large companies have gobbled up the more innovative small companies. We must enjoy these times while we can.
