I love this bike! I have been asked to review the battery I just bought but I only used it once. The bike however is the greatest purchase since my kayak 15 years ago. I cannot think of any negatives which is unusual for me.
Aventon Pace 500 E-Bike Replacement Battery
The life of the battery is not at full capacity according to light bar indicator. I regret buying it for $400.00.
Battery was shipped in a well padded container, double boxed. No issues with it. Worked as well as the original, and let me go full speed on my commute without fear of running out of juice (now that I carry 2 batteries).
Only hiccup was with FedEx delivery. Since it's classified as hazmat, I could not re-route the shipment for pickup at store. Even though I requested a drop off time, they showed up when no one was home (have to pay extra for an appointment delivery). It seemed that I was really stuck, and may not ever get the battery at all as they needed a signature, and I could not get an option online for alternative pickup. The thing that worked at the end was calling FedEx ground, and arranging for a pickup there. There was still a series of screwups there, as they never called us back for when the driver returned. But in the end was able to find the package in the trailer when we were there in person, and facilitated the pickup of the package. Having the bike delivered was not nearly so difficult as just have an extra battery delivered.
I bought a second battery for my Pace 500 so I could alternate between a charged battery and the one being charged. The battery is also great as a spare when I go out on our 34-mile trail, just in case I don't make it back on one charge. The battery is less expensive than ones I've seen for other bikes, so that is a plus.
