I have the Fiido M1 and have just tried it on two forest mountain bike trails in the UK, it was fully charged at the start and still had 1 bar showing on my return after 24km having completed the trail although it took a bit of time getting used to how the bike handled it performed exceedenly well and coped with the hills and tight bends of the trail very well and the suspension absorbed the rough trail well and the rugged forrest roads. The brakes coped very well on the very steep downhill sections although it wore out the rear rubber brake pads which I have just reordered. The gearing worked well along with the pedal assist even though only 7 speed.
My overall impression of the bike on my off road adventure is extremely high and totally think it was a good buy.
