Highly recommended battery replacement 5th Wheel

Ordered the battery online and it showed up super quick. It was an exact replacement battery to keep on hand. My son loves his new 5th Wheel electric bike. Perfect for a 3-4 year old learning balancing. So far the batteries last an extremely long time (hours) before they need to be switched out. Highly recommended.
