The X2000 is lighter than the X3000. This is a noticeable plus.
But at the same time, the battery is also noticeably smaller, only 12.8 ampere-hours. This reduces its maximum current and significantly limits the speed. For my weight of ~100kg, this is 25 km per hour - the limit for a charged battery, but it quickly drops to 22 km per hour. The speed uphill is also noticeably lower, 12-18 km per hour.
Otherwise, it's a very good bike.
After installing the trunk, backpack and battery, it weighs 29 kg.
It would be very desirable in future to have a 15-18 ampere-hour 48 volt battery compatible with this model of X2000.
The product is good, I recommend it to everyone.
