2002 Lafree Sport (built by Giant)
I have tried E-bikes. I think they will do better in everyday use, such as Bike-Share, as opposed to personal use, which had battery issues. I don't necessarily have the 5 hours after each use free time available to nurse the battery pack, without overcharging or burning the house down. I could see it would be just as easy to watch voltage and temperature of 20, or even 100 batteries, rather than devoting my time to just one battery. Also, today's Battery Management System 's are much more reliable and can shut off when the charge is full , autonomously.
