Great replacement battery my bike rides like a dream now. Although I have no idea where to recycle the old one 🙂
Very pleased with the overall service, have yet to fit the battery to my bike as it needs some modifications to fit, this new battery is slightly larger than the one I am replacing, but I'm pretty confident it will fit ok, I hope this new battery will last as long as the old one which was approx. 5yrs. I recommend DYU ebike.
Thank you! Very fast return shipping battery and refund money.
Great battery amazing seller!
Had a problem with shipment and thought I’d just get a refund but seller reached out and made it right! Great battery! Gives me loads of range. Used it to retrofit an older ebike that would have costed way more. I’m very satisfied
Better than expected. Fast shipping, High quality.
Came faster than estimated arrival date. I even emailed the seller to confirm the arrival date and they responded right away to let me know the battery would arrive before I left for vacation.
The battery took 20 minutes to install. No surprises. It worked as expected right away. We've been using the scooter for about 3 weeks and can confirm it has WAY more power than the stock battery, and lasts forever. Used to charge our bike every day or two - now we charge it every week or two.
