Years of satisfaction
I have 5,600 miles on my trek ebike. At around 3,000 miles I purchased a second battery so I could take longer trips. I am about to replace my original Bosch Power Pack 400 because it finally gave out. For the last couple of years I could get 20+ miles at the second highest power setting on my class III ebike. On the first setting of support I could get 30+ miles. My second battery is the 500 and I do not think it is worth the extra money for the small increase in capacity, and I have to wonder if it will last as long as my original 400. So I am buying another 400.
Worthless garbage
I bought a Trek Vista 2+2 e-bike in September of 2020 to begin e-commuting 15 miles to work in AZ. I bought the bike in Montana. The very next day when I got it home, the PowerPack 400 went dead. I took it to a Trek dealer who confirmed the failure, and I made a claim under warranty. The replacement lasted till November of 2021, when it suffered total failure again after less then 1800 miles and 100 charging cycles. Then, while shopping for a replacement, to my astonishment and outrage, I found a replacement would cost, with tax, over $700. In terms of miles per gallon, at 25mpg and $3.50/gallon, $700 would provide 5000 miles of travel on gasoline. At 1800 miles before failure, his battery cost, ignoring charge cost, the equivalent of $9.72 per gallon of gas.
Battery is Worthless
I bought the electra townie go bike brand new. The battery had maybe 10 charges on it before it died and wouldn't charge again. Super frustrating.
dead
It worked fine for about 4 years, and then suddenly just totally stopped charging. This is way too short a lifespan for the replacement cost, but then what can you do? I have to buy another one, but I'm not happy about it.
