Fiido D4s - Top Speed 50KM/H!? And how to increase it?

I have received my Fiido D4s electric bike. First things first. Lets remove the legal speed limit and check how fast does the new bike go? Buy Fiido D4s - All Fiido D4s models - If you want to receive bike in 1-2weeks. Get Fiido D2 that are still in stock.
