I haven't tried it yet, I'm waiting for the motor, I hope it's a real 48 Volts and not 52V.

I am very happy with my purchase. The product matches the description, arrived in good condition and within the estimated timeframe. The quality is in line with the price and has exceeded my expectations. Without a doubt, I will repeat the purchase and recommend this item to those who are looking for something similar.

Better range than i expected.

With some pedaling, got 2 hours at just 15-20% of battery used.

If not pushed, i bet this can last for a whole day on mostly flat terrain.
